HISTORY New entity in IFC Release 1.5.1

SELECT

IfcOrganization An organization. IfcPerson A person. IfcPersonAndOrganization A person related to an organization.

typedef IfcUtil::IfcBaseClass IfcAppliedValueSelect

IfcAppliedValueSelect defines the selection of whether a value (expressed as a ratio) or an amount should be used as the value for an IfcAppliedValue.

Select from:

IfcMeasureWithUnit IfcMonetaryMeasure IfcRatioMeasure

HISTORY: New SELECT type in IFC 2x2.

Use definitions Selecting IfcMeasureWithUnit allows the specification of both the actual figure for the value together with the currency in which the value is represented. Selecting IfcMonetaryMeasure allows the specification only of the value, the currency being as set by the global context Selecting IfcRatioMeasure assumes that the amount is a percentage or other REAL number. Note that if the amount is normally specified as -20%, then this figure will need to be converted to a multiplier of 0.8

typedef IfcUtil::IfcBaseClass IfcAxis2Placement

Definition from ISO/CD 10303-42:1992: This select type collects together both versions of the placement as used in two dimensional or in three dimensional Cartesian space. This enables entities requiring this information to reference them without specifying the space dimensionality.

Select:

Type Definition

IfcExternalReference Light distribution is represented by a standard photometric data file such as Eulumdat, IES, CIBSE TM14.

IfcLightIntensityDistribution For representing a light distribution directly the following values needs to be given in a table like structure with column and row headings. These headings should contain the angles (C/γ or B/β ) and the table body contains the intensity values, (normally normalized to cd/Klm). The angles can be non- equidistant and the angle steps can be almost any value in the valid range, so a list of all available angles in both directions covers all cases.

A request is the act or instance of asking for something, such as a request for information, bid submission, or performance of work.

Requests may take many forms depending on the need including fault reports for maintenance, requests for small works, and purchase requests (where these are to be made through a help desk or buying function).

HISTORY: New entity in IFC2x2 IFC2x4 CHANGE RequestID renamed to Identification and promoted to supertype IfcControl, attributes PredefinedType, Status, and LongDescription added.

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Refer to the documentation at the supertype IfcControl and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ActionRequest

Declaration Use Definition The IfcActionRequest may be declared within the project using the IfcRelDeclares relationship where RelatingContext refers to the single IfcProject and RelatedDefinitions contains the IfcActionRequest. Alternatively, if the IfcActionRequest is aggregated within an IfcWorkPlan, then it shall not have a direct declaration relationship (whereas the containing work plan may have a declaration relationship).

Composition Use Definition As shown in Figure 155, an IfcActionRequest may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcActionRequest and RelatedObjects contains one or more components. Aggregation use is defined for the following predefined types:

(All Types): May contain IfcCostSchedule components. A cost schedule may indicate costs and quantities where the cost schedule type may designate whether rates and/or quantities are estimated or final. Such cost schedule may have assigned cost items indicating detail, where each cost item may have assigned products, processes, or resources.

The IfcActionRequest may be nested into sub-items using IfcRelNests where RelatingObject refers to the enclosing IfcActionRequest and RelatedObjects contains one or more sub-items. Nesting use is defined for the following predefined types:

(All Types): May contain IfcActionRequest sub-items. A request may be nested into follow-up requests, in order of issue.

Figure 155 — Action request composition

Assignment Use Definition As shown in Figure 156, an IfcActionRequest may be assigned to the following entities using relationships as indicated:

IfcActor (IfcRelAssignsToActor): Person or organization issuing the request such as a tenant or owner.

The IfcActionRequest may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcActionRequest and RelatedObjects contains one or more objects of the following types: IfcActor: Person or organization(s) fulfilling the request such as a facilities manager or contractor.

Figure 156 — Action request assignment

Approval Use Definition Approvals may be associated to indicate the status of acceptance or rejection using the IfcRelAssociatesApproval relationship where RelatingApproval refers to an IfcApproval and RelatedObjects contains the IfcActionRequest. Approvals may be split into sub-approvals using IfcApprovalRelationship to track approval status separately for each party where RelatingApproval refers to the higher-level approval and RelatedApprovals contains one or more lower-level approvals. The hierarchy of approvals implies sequencing such that a higher-level approval is not executed until all of its lower-level approvals have been accepted.

class IfcAnnotation : public Ifc2x3::IfcProduct

Definition from IAI: An annotation is a graphical representation within the geometric (and spatial) context of a project, that adds a note or meaning to the objects which constitutes the project model. Annotations include additional line drawings, text, dimensioning, hatching and other forms of graphical notes.

NOTE Additional presentation information (often 2D) such as tag number, hatching, etc., that is directly related to a particular product representation is included within the IfcProductDefinitionShape having various IfcShapeRepresentation’s of the IfcElement (and its subtypes). Only those presentation information, that cannot be directly related to a single product, have to be wrapped within the IfcAnnotation.

If available, the annotation should be related to the spatial context of the project, by containing the annotation within the appropriate level of the building structure (site, building, storey, or space). This is handled by the IfcRelContainedInSpatialStructure relationship.

HISTORY: New entity in Release IFC2x Edition 2.

Use definition

The IfcAnnotation can provide specific 0D, 1D, and 2D geometric items as representation of the annotation, offering annotation point, curves, and surfaces.

‘Annotation point’ is an annotation provided by a point that has additional semantic. The inherited attribute ObjectType should be used to capture the type of point annotation, some predefined values are:

‘Survey’: A survey point has a set of cartesian coordinates determined by its location at point. These coordinates are determined relative to the coordinates of a reference point, which acts as the datum for the survey. The difference in elevation of the survey points enables terrain to be determined.

‘Annotation curve’ is an annotation provided by a curve that has additional semantic. The inherited attribute ObjectType should be used to capture the type of curve annotation, some predefined values are:

‘ContourLine’: A line of constant elevation typically used on geographic maps where the spacing of lines at constant intervals of elevation may be used as an indication of slope.

‘IsoBar’: A line of constant pressure typically used on weather maps or to show pressure gradient in spaces, chambers or externally.

‘IsoLux’: A line of constant illumination typically used to show the distribution of illumination levels and/or daylighting in a space or externally.

‘IsoTherm’: A line of constant temperature typically used to show the distribution and effect of heating or cooling within a space or to show temperature distribution on a geographic map.

‘Annotation surface’ is an annotation provided by a surface that has additional semantic. The inherited attribute ObjectType should be used to capture the type of surface annotation, some predefined values are:

‘SurveyArea’: A surface patch based on survey points.

Geometry Use Definitions

The geometric representation of any IfcAnnotation is given by the IfcProductDefinitionShape and IfcLocalPlacement allowing multiple geometric representations.

Local Placement

The local placement for any IfcAnnotation is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement, which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that.

If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations

The standard representation of IfcAnnotation is defined using ‘Annotation2D’, when using 2D geometry, hatching and text, ‘GeometricCurveSet’ when using points and curves, or, when including als surfaces, the ‘GeometricSet’ geometry. Geometric representation items may be styled items by adding the style information.

Annotation2D Representation This representation is used, when the representation of the IfcAnnotation includes specific drafting representation elements. The Annotation may have:

subtypes of IfcPoint, IfcCurve being 2D

directly as Items, or within an IfcGeometricCurveSet

subtypes of IfcAnnotationFillArea for hatches

subtypes of IfcDefinedSymbol for symbols

subtypes of IfcTextLiteral for text

subtypes of IfcDraughtingCallout for dimensions

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Annotation’

RepresentationType : ‘Annotation2D’

Annotation Curve Representation This representation is used, when the representation of the IfcAnnotation does not includes specific drafting representation elements. The Annotation may have:

subtypes of IfcPoint, IfcCurve being 2D

directly as Items, or within an IfcGeometricCurveSet

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Annotation’

RepresentationType : ‘GeometricCurveSet’

Annotation Surface Representation This representation is used, when the representation of the IfcAnnotation does includes surfaces. The Annotation may have:

subtypes of IfcPoint, IfcCurve, or IfcSurface

directly as Items, or within an IfcGeometricCurveSet

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

class IfcAnnotationFillArea : public Ifc2x3::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-46:1992: An annotation fill area is a set of curves that may be filled with hatching, colour or tiling. The annotation fill are is described by boundaries which consist of non-intersecting, non-self-intersecting closed curves. These curves form the boundary of planar areas to be filled according to the style for the annotation fill area.

NOTE: A curve that is not surrounded by any other curve is a border between an unfilled area on the outside and a filled area on the inside. Another curve may surround an unfilled area if it is surrounded by another curve whose inside is a filled area.

Figure 300 (from ISO 10303-46) illustrates annotation fill area.

Figure 300 — Annotation fill area

NOTE Corresponding ISO 10303 name: annotation_fill_area. Please refer to ISO/IS 10303-46:1994 for the final definition of the formal standard.

The IfcAnnotationFillArea defines an area by a definite OuterBoundary, that might include InnerBoundaries. The areas defined by the InnerBoundaries are excluded from applying the fill area style.

Informal Proposition:

Any curve that describes an inner boundary shall not intersect with, nor include, another curve defining an inner boundary. The curve defining the outer boundary shall not intersect with any curve defining an inner boundary, nor shall it be surrounded by a curve defining an inner boundary.

class IfcAppliedValue : public IfcUtil::IfcBaseEntity

IfcAppliedValue is an abstract supertype that specifies the common attributes for cost values.

HISTORY: New Entity in IFC2x2. Modifed in IFC2x4 to use IfcDate for date values.

Use definitions The extent of the IfcAppliedValue is determined by the AppliedValue attribute which may be defined either as an IfcMeasureWithUnit or as an IfcMonetaryMeasure or as an IfcRatioMeasure via the IfcAppliedValueSelect type.

Optionally, an IfcAppliedValue may have an applicable date. This is intended to fix the date on which the value became relevant for use. It may be the date on which the value was set in the model or it may be a prior or future date when the value becomes operable.

Similarly, an IfcAppliedValue may have a ‘fixed until’ date. This is intended to fix the date on which the value ceases to be relevant for use.

An instance of IfcAppliedValue may have a unit basis asserted. This is defined as an IfcMeasureWithUnit that determines the extent of the unit value for application purposes. It is assumed that when this attribute is asserted, then the value given to IfcAppliedValue is that for unit quantity. This is not enforced within the IFC schema and thus needs to be controlled within an application.

Applied values may be referenced from a document (such as a price list). The relationship between one or more occurrences of IfcAppliedValue (or its subtypes) is achieved through the use of the IfcExternalReferenceRelationship in which the document provides the IfcExternalReferenceRelationship.RelatingExtReference and the value occurrences are the IfcExternalReferenceRelationship.RelatedResourceObjects.

Note: As well as the normally expected units of measure such as length, area, volume etc., costs may be based on units of measure which need to be defined e.g. sack, drum, pallet, item etc. Unit costs may be based on quantities greater (or lesser) than a unitary value of the basis measure. For instance, timber may have a unit cost rate per X meters where X > 1; similarly for cable, piping and many other items. The basis number may be either an integer or a real value.

Note: This attribute should be asserted for all circumstances where the cost to be applied is per unit quantity. It may be asserted even for circumstances where an item price is used, in which case the unit cost basis should be by item (or equivalent definition).

class IfcAppliedValueRelationship : public IfcUtil::IfcBaseEntity

An IfcAppliedValueRelationship is a relationship class that enables cost values to be aggregated together as components of another cost value.

HISTORY New Entity in Release IFC2.0.

IFC2x4 CHANGE Subtyped from IfcResourceLevelRelationship, attribute order changed.

Use definitions Dependency relationships can exist between applied values on the basis that one particular value may be determined by operations on one or more other values. This is captured through the IfcAppliedValueRelationship entity. In this relationship, one instance of IfcAppliedValue acts as the principal (IfcAppliedValueRelationship.ComponentOf) whose value may be determined from the instances of IfcAppliedValue that are defined as its components (IfcAppliedValueRelationship.Components) An IfcAppliedValueRelationship has an ArithmeticOperator attribute that specifies the form of arithmetical operation implied by the relationship. A practical consideration when using the applied value relationship is that when the arithmetic operator is ADD, then the type of the IfcAppliedValue.AppliedValue attribute will be IfcMeasureWithUnit or IfcMonetaryMeasure while if the arithmetic operator is MULTIPLY, then the type of the IfcAppliedValue.AppliedValue attribute for one instance of IfcAppliedValue will be IfcMeasureWithUnit or IfcMonetaryMeasure while for other instances it will be IfcRatioMeasure. If the arithmetic operator is SUBTRACT or DIVIDE then there can only be two occurrences of IfcAppliedValue that can contribute and the order in which they occur is significant. The value of (A - B) will usually differ from the value of (B - A) whilst (X / Y) is the reciprocal of (Y / X).

Figure 239 illustrates one level aggregation of applied values. A relationship exists between applied value A and applied values B, C and D such that the value of A is determined by the addition of B, C and D such that: A = B + C + D

Figure 239 — Applied value relationship single level

Figure 240 illustrates two level aggregation of applied values. It is possible to develop more complex applied value specifications by creating hierarchies of applied value relationships. In the diagram, the development of a applied value is shown whereby, because B = E * F and D = G * H * J, then: A = ((E * F) + C + (G * H * J)).

class IfcAsset : public Ifc2x3::IfcGroup

An asset is a uniquely identifiable grouping of elements acting as a single entity that has a financial value or that can be operated on as a single unit.

An asset is generally the level of granularity at which maintenance operations are undertaken. An asset is a group that can contain one or more elements. Whilst the financial value of a component or element can be defined, financial value is also defined for accounting purposes at the level of the asset. There are a number of actors that can be associated with an asset, each actor having a role. Actors within the scope of the project are indicated using the IfcRelAssignsToActor relationship in which case roles should be defined through the IfcActorRole class; otherwise principal actors are identified as attributes of the class. In the existence of both, direct attributes take precedence. There are a number of costs that can be associated with an asset, each cost having a role. These are specified through the OriginalValue, CurrentValue, TotalReplacementCost and DepreciatedValue attributes.

HISTORY: New entity in IFC2x. In IFC2x4, all attributes made optional and date values changed to use IfcDate.

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Refer to the documentation at the supertype IfcGroup and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_Asset

Classification Use Definition Classifications may be applied using IfcRelAssociatesClassification where RelatedObjects contains the IfcAsset and RelatingClassification refers to an IfcClassification or IfcClassificationReference.

IfcClassificationReference: The operating function of an asset within an organization may be particularly valuable in situations where one organization provides and maintains core services and another organization adds and maintains terminal services. It can classify who owns and is responsible for the asset. Operating function can be designated through the use of one or more classification references.

Assignment Use Definition The IfcAsset may be assigned to the following entities using relationships as indicated:

IfcActor (IfcRelAssignsToActor): Indicates the actor who owns, uses, or is responsible for the asset (as indicated by role in relationship), if such actor is within the scope of the project. IfcCostItem (IfcRelAssignsToControl): Indicates a cost item encompassing the asset.

The IfcAsset may have assignments of its own using the IfcRelAssignsToGroup relationship where RelatingGroup refers to the IfcAsset and RelatedObjects contains one or more objects of the following types: IfcElement: Physical elements that comprise the asset.

class IfcAsymmetricIShapeProfileDef : public Ifc2x3::IfcIShapeProfileDef

IfcAsymmetricIShapeProfileDef defines a section profile that provides the defining parameters of a singly symmetric I-shaped section. Its parameters and orientation relative to the position coordinate system are according to the following illustration. The centre of the position coordinate system is in the profile’s centre of the bounding box.

The inherited attributes are redefined as:

OverallWidth BottomFlangeWidth FlangeThickness BottomFlangeThickness FilletRadius BottomFlangeFilletRadius

The overall width of the profile is implicitly given by the maximum of the bottom flange width and the top flange width.

IfcAsymmetricIShapeProfileDef can also be used to model rail profiles if the application scenario does not require a full explicit shape model of the rail profile. Alternatively, IfcArbitraryClosedProfileDef can be used to provide the exact shape of rail profiles. Either way, a reference to an external document or library should be provided to further define the profile as described at IfcProfileDef.

HISTORY New entity in Release IFC2x Edition 2.

IFC2x3 CHANGE All profile origins are now in the center of the bounding box. The attribute CentreOfGravityInY has been made OPTIONAL.

IFC2x4 CHANGE Bottom flange is not necessarily wider than top flange. TopFlangeThickness changed from OPTIONAL to mandatory. Type of TopFlangeFilletRadius relaxed to allow for zero radius. Trailing attribute CentreOfGravityInY deleted, use respective property in IfcExtendedProfileProperties instead.

Figure 310 illustrates parameters of the asymmetric I-shaped section definition. The parameterized profile defines its own position coordinate system. The underlying coordinate system is defined by the swept area solid that uses the profile definition. It is the xy plane of:

IfcSweptAreaSolid.Position

By using offsets of the position location, the parameterized profile can be positioned centric (using x,y offsets = 0.), or at any position relative to the profile. The parameterized profile is defined by a set of parameter attributes. In the illustrated example, the ‘CentreOfGravityInY’ property in IfcExtendedProfileProperties, if provided, is negative.

class IfcBeam : public Ifc2x3::IfcBuildingElement

Definition from ISO 6707-1:1989: Structural member designed to carry loads between or beyond points of support, usually narrow in relation to its length and horizontal or nearly so.

An IfcBeam is a horizontal, or nearly horizontal, structural member that is capable of withstanding load primarily by resisting bending. It represents such a member from an architectural point of view. It is not required to be load bearing.

NOTE The representation of a beam in a structural analysis model is provided by IfcStructuralCurveMember being part of an IfcStructuralAnalysisModel.

NOTE For any longitudial structural member, not constrained to be predominately horizontal nor vertical, or where this semantic information is irrelevant, the entity IfcMember should be used.

The IFC specification provides two entities for beam occurrences:

IfcBeamStandardCase used for all occurrences of beams, that have a profile defined that is swept along a directrix. The profile might be changed uniformly by a taper definition along the directrix. The profile parameter and its cardinal point of insertion can be fully described by the IfcMaterialProfileSetUsage. These beams are always represented geometricly by an ‘Axis’ and a ‘SweptSolid’ or ‘AdvancedSweptSolid’ shape representation (or by a ‘Clipping’ geometry based on the swept solid), if a 3D geometric representation is assigned. In addition they have to have a corresponding IfcMaterialProfileSetUsage assigned. NOTE View definitions and implementer agreements may further constrain the applicable geometry types, for example, by excluding tapering from an IfcBeamStandardCase implementation.

IfcBeam used for all other occurrences of beams, particularly for beams with changing profile sizes along the extrusion, or beams defined by non-linear extrusion, or beams having only ‘Brep’, or ‘SurfaceModel’ geometry.

HISTORY New entity in IFC Release 1.0

Type Use Definition IfcBeam defines the occuurence of any beam, common information about beam types (or styles) is handled by IfcBeamType. The IfcBeamType (if present) may establish the commontype name, usage (or predefined) type, common material layer set, common set of properties and common shape representations (using IfcRepresentationMap). The IfcBeamType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute. If no IfcBeamType is attached (i.e. if only occurrence information is given) the PredefinedType should be provided. If set to .USERDEFINED. a user defined value can be provided by the ObjectType attribute. Material Use Definition The material of the IfcBeam is defined by the IfcMaterialProfileSet or as fallback by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Note It is illegal to assign an IfcMaterialProfileSetUsage to an IfcBeam. Only the subtype IfcBeamStandardCase supports this concept. Material information can also be given at the IfcBeamType, defining the common attribute data for all occurrences of the same type. It is then accessible by the inverse IsTypedBy relationship pointing to IfcBeamType.HasAssociations and via IfcRelAssociatesMaterial.RelatingMaterial to IfcMaterialProfileSet or IfcMaterial. If both are given, then the material directly assigned to IfcBeam overrides the material assigned to IfcBeamType. Property Set Use Definition The property sets relating to the IfcBeam are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcBeam are part of this IFC release:

Pset_BeamCommon: common property set for all beam occurrences

Property sets can also be given at the IfcBeamType, defining the common property data for all occurrences of the same type. It is then accessible by the inverse IsTypedBy relationship pointing to IfcBeamType.HasPropertySets. If both are given, then the properties directly assigned to IfcBeam overrides the properties assigned to IfcBeamType. Quantity Use Definition The quantities relating to the IfcBeam are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to MethodOfMeasurement. Quanties shall be never assigned to the IfcBeamType.

Qto_BeamBaseQuantities: base quantities for all beam occurrences.

Containment Use Definition The IfcBeam, as any subtype of IfcBuildingElement, may participate in two different containment relationships. The first (and in most implementation scenarios mandatory) relationship is the hierachical spatial containment, the second (optional) relationship is the aggregation within an element assembly.

The IfcBeam is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, refering to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes of IfcSpatialStructureElement are valid spatial containers, with IfcBuildingStorey being the default container. The IfcBeam may be aggregated into an element assembly using the objectified relationship IfcRelAggregates, refering to it by its inverse attribute SELF\IfcObjectDefinition.Decomposes. Any subtype of IfcElement can be an element assembly, with IfcElementAssembly as a special focus subtype. In this case it should not be additionally contained in the project spatial hierarchy, i.e. SELF\IfcElement.ContainedInStructure should be NIL.

Geometry Use Definition The geometric representation of IfcBeam is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are: Local Placement The local placement for IfcBeam is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement, which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that.

Exception: If the IfcBeam is part of an assembly, the PlacementRelTo relationship of IfcLocalPlacement shall point to the local placement of the container element, e.g. IfcElementAssembly,

If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representation Currently, the ‘Axis’, ‘Body’, and ‘Box’ representations are supported. The ‘Box’ representation includes the representation type ‘BoundingBox’ and is explained at IfcBuildingElement. Axis Representation The axis geometric representation of IfcBeam is defined using the ‘Axis’ representation.

RepresentationIdentifier : ‘Axis’ RepresentationType : ‘Curve2D’, ‘Curve3D’

The ‘Axis’ can be used to represent the system axis and length of a beam that may extent the body length. Body Representation The body representation of IfcBeam can be represented using the representation types ‘SweptSolid’, ‘Clipping’, ‘AdvancedSweptSolid’, ‘MappedRepresentation’, ‘SurfaceModel’, and ‘Brep’. The representation types ‘SurfaceModel’ and ‘Brep’ are explained at IfcBuildingElement. SweptSolid Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SweptSolid’

The following additional constraints apply to the ‘SweptSolid’ representation type:

Solid: IfcExtrudedAreaSolid, IfcRevolvedAreaSolid shall be supported Profile: all subtypes of IfcProfileDef (with exception of IfcArbitraryOpenProfileDef) Extrusion: All extrusion directions shall be supported.

Figure 71 illustrates the ‘SweptSolid’ geometric representation. There are no restrictions or conventions on how to use the local placement (black), solid of extrusion placement (red) and profile placement (green).

Figure 71 — Beam swept solid

Figure 72 illustrates the use of non-perpendicular extrusion to create the IfcExtrudedAreaSolid.

Figure 72 — Beam non-perpendicular extrusion

Clipping Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Clipping’

The following constraints apply to the advanced representation:

Solid: see ‘SweptSolid’ geometric representation Profile: see ‘SweptSolid’ geometric representation Extrusion: see ‘SweptSolid’ geometric representation Boolean result: The IfcBooleanClippingResult shall be supported, allowing for Boolean differences between the swept solid (here IfcExtrudedAreaSolid) and one or several IfcHalfSpaceSolid (or its subtypes).

Figure 73 illustrates use of IfcBooleanClippingResult between an IfcExtrudedAreaSolid and an IfcHalfSpaceSolid to create a clipped body.

Figure 73 — Beam clipping

AdvancedSweptSolid Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘AdvancedSweptSolid’

The following additional constraints apply to the ‘AdvancedSweptSolid’ representation type:

Solid: IfcSurfaceCurveSweptAreaSolid, IfcFixedReferenceSweptAreaSolid, IfcExtrudedAreaSolidTapered, IfcRevolvedAreaSolidTapered shall be supported. NOTE View definitions and implementer agreement can further constrain the allowed swept solid types.

Profile: see ‘SweptSolid’ geometric representation Extrusion: not applicable

MappedRepresentation Representation Type The ‘MappedRepresentation’ representation is supported as it allows for reusing the geometry definition of the beam type at all occurrences of the same type. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘MappedRepresentation’

The same constraints, as given for the ‘SweptSolid’, ‘Clipping’, ‘AdvancedSweptSolid’, ‘SurfaceModel’, and ‘Brep’ geometric representation, shall apply to the MappedRepresentation of the IfcRepresentationMap.

class IfcBeamType : public Ifc2x3::IfcBuildingElementType

Definition from IAI: The element type IfcBeamType defines commonly shared information for occurrences of beams. The set of shared information may include:

common properties within shared property sets common material information common profile definitions common shape representations

It is used to define a beam specification, or beam style (i.e. the specific product information that is common to all occurrences of that beam type). Beam types may be exchanged without being already assigned to occurrences. Occurrences of the IfcBeamType within building models are represented by instances of IfcBeamStandardCase if the IfcBeamType has a single associated IfcMaterialProfileSet; otherwise they are represented by instances of IfcBeam. Occurrences of the IfcBeamType within structural analysis models are represented by instances of IfcStructuralCurveMember, or its applicable subtypes. HISTORY New entity in Release IFC2x Edition 2. Material Use Definition The material of the IfcBeamType is defined by the IfcMaterialProfileSet or as fall back by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Note: It is illegal to assign an IfcMaterial to an IfcBeamType, if there is at least one occurrences. of IfcBeamStandardCase for this type. Property Set Use Definition: The shared property sets relating to the IfcBeamType are defined by the IfcPropertySet and are attached by the HasPropertySets attribute. The following property set definitions specific to the IfcBeamType are part of this IFC release: NOTE There is no differentiation between properties within the property set that are only assignable to IfcBeamType and those that are only assignable to IfcBeam. If the same property is assigned to the IfcBeamType and the IfcBeam being an occurrence of the IfcBeamType, then the occurrence property overrides the type property.

Pset_BeamCommon: common property set for all beam types.

Profile Use Definition: The shared profile definition is defined by assigning an IfcMaterialProfileSet (see material use definition above). The IfcMaterialProfile refers to the subtype of IfcProfileDef that is the common profile for all beam occurrence, if used. It is only applicable if the IfcBeamType has only occurrences of type IfcBeamStandardCase (see definition of IfcBeamStandardCase for further information). NOTE The attribute ProfileName of the IfcProfileDef subtype, referenced in IfcMaterialProfile should contain a standardized profile name according to local standards. However, an additional geometric representation of the profile is necessary (e.g. as IfcExtrudedAreaSolid). An importing application is allowed to check for the existence of the profile name: in case of identifying it as a standardized name, the corresponding profile geometry and possibly other cross sectional properties can be read from a library. Otherwise the geometric representation and possible non geometric IfcProfileProperties have to be used. Geometry Use Definition: The IfcBeamType may define the shared geometric representation for all beam occurrences. The RepresentationMaps attribute refers to a list of IfcRepresentationMap’s, that allow for multiple geometric representations (e.g. with IfcShaperepresentation’s having an RepresentationIdentifier ‘Box’, ‘Axis’, or ‘Body’). It is only applicable if the IfcBeamType has only occurrences of type IfcBeam (See geometric use definition of IfcBeam for further information). NOTE If the IfcBeamType has an associated IfcMaterialProfileSet, then no shared geometric representation shall be provided. NOTE The product shape representations are defined as RepresentationMaps (attribute of the supertype IfcTypeProduct), which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[n] being an IfcMappedItem. See IfcTypeProduct for further information. NOTE The values of attributes RepresentationIdentifier and RepresentationType of IfcShapeRepresentation are restricted in the same way as those for IfcBeam and IfcBeamStandardCase

HOLLOWCORE: A wide often prestressed beam with a hollow-core profile that usually serves as a slab component. LINTEL: A beam or horizontal piece of material over an opening (e.g. door, window). SPANDREL: A tall beam placed on the facade of a building. One tall side is usually finished to provide the exterior of the building. Can be used to support joists or slab elements on its interior side.

NOTE They are also referred to as “spandrel

The IfcBlock is a Construction Solid Geometry (CSG) 3D primitive. It is defined by a position and a positve distance along the three orthogonal axes. The inherited Position attribute has the IfcAxisPlacement3D type and provides:

SELF\IfcCsgPrimitive3D.Position: The location and orientation of the axis system for the primitive. SELF\IfcCsgPrimitive3D.Position.Location: The block has one vertex at location and the edges are aligned with the placement axes in the positive sense.

The XLength, YLength, and ZLength attributes define the size of the IfcBlock along the three axes. The following definitions from ISO 10303-42 apply:

A block is a solid rectangular parallelepiped, defined with a location and placement coordinate system. The block is specified by the positive lengths x, y, and z along the axes of the placement coordinate system, and has one vertex at the origin of the placement coordinate system.

Figure 250 illustrates geometric parameters of a block where the block positioned within its own placement coordinate system. The values for XLength, YLength, and ZLength are applied to the positive direction of the X, Y, and Z axis.

class IfcBooleanResult : public Ifc2x3::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-42:1992: A Boolean result is the result of a regularized operation on two solids to create a new solid. Valid operations are regularized union, regularized intersection, and regularized difference. For purpose of Boolean operations, a solid is considered to be a regularized set of points. The final Boolean result depends upon the operation and the two operands. In the case of the difference operator the order of the operands is also significant. The operator can be either union, intersection or difference. The effect of these operators is described below:

Union on two solids is the new solid that is the regularization of the set of all points that are in either the first operand or the second operand or in both. Intersection on two solids is the new solid that is the regularization of the set of all points that are in both the first operand and the second operand. The result of the difference operation on two solids is the regularization of the set of all points which are in the first operand, but not in the second operand.

NOTE For example if the first operand is a block and the second operand is a solid cylinder of suitable dimensions and location, the boolean result produced with the difference operator would be a block with a circular hole.

NOTE Corresponding ISO 10303-42 entity: boolean_result. The derived attribute Dim has been added at this level and was therefore demoted from the geometric_representation_item. Please refer to ISO/IS 10303-42:1994, p.175 for the final definition of the formal standard.

Definition from ISO/CD 10303-42:1992: A box domain is an orthogonal box parallel to the axes of the geometric coordinate system which may be used to limit the domain of a half space solid. A box domain is specified by the coordinates of the bottom left corner, and the lengths of the sides measured in the directions of the coordinate axes.

Every semantic object having a physical extent might have a minimum default representation of a bounding box. The bounding box is therefore also used as minimal geometric representation for any geometrically represented object. Therefore the IfcBoundingBox is subtyped from IfcGeometricRepresentationItem.

NOTE Corresponding ISO 10303-42 entity: box_domain, please refer to ISO/IS 10303-42:1994, p. 186 for the final definition of the formal standard. In IFC the bounding box can also be used outside of the context of an IfcBoxedHalfSpace.

HISTORY New entity in IFC Release 1.0.

As shown in Figure 252, the IfcBoundingBox is defined with its own location which can be used to place the IfcBoundingBox relative to the geometric coordinate system.

class IfcBoxedHalfSpace : public Ifc2x3::IfcHalfSpaceSolid

Definition from ISO/CD 10303-42:1992: This entity is a subtype of the half space solid which is trimmed by a surrounding rectangular box. The box has its edges parallel to the coordinate axes of the geometric coordinate system.

NOTE The purpose of the box is to facilitate CSG computations by producing a solid of finite size.

The IfcBoxedHalfSpace is used (as its supertype IfcHalfSpaceSolid) only within Boolean operations. It divides the domain into exactly two subsets, where the domain in question is that of the attribute Enclosure. The purpose of the attribute Enclosure is to provide a search box for the other operand in the Boolean operation. It shall be sufficiently large to fully enclose the resulting solid after the Boolean operation with the half space. It however does not alter the final result. The result of the Boolean operation would be the same, as if executed by the supertype IfcHalfSpaceSolid. See Figure 253 below.

Figure 253 — Boxed half space operands

NOTE Corresponding ISO 10303-42 entity: boxed_half_space, please refer to ISO/IS 10303-42:1994, p. 185 for the final definition of the formal standard. The IFC class IfcBoundingBox is used for the definition of the enclosure, providing the same definition as box_domain.

HISTORY New entity in IFC Release 1.5.1, improved documentation available in IFC Release 2x.

IFC2x4 CHANGE Usage correct, position coordinate system for Enclosure is the object coordinate system.

The IfcBoundingBox (relating to ISO 10303-42:1994 box_domain) that provides the enclosure is given for the convenience of the receiving application to enable the use of size box comparison for efficiency (for example, to check first whether size boxes intersect, if not no calculations has to be done to check whether the solids of the entities intersect).

The Enclosure therefore helps to prevent dealing with infinite-size related issues. The enclosure box is positioned within the object coordinate system, established by the ObjectPlacement of the element represented (for example, by IfcLocalPlacement). Figure 254 shows the Enclosure box being sufficiently large to fully enclose the Boolean result.

class IfcBSplineCurve : public Ifc2x3::IfcBoundedCurve

Definition from ISO/CD 10303-42:1992: A B-spline curve is a piecewise parametric polynomial or rational curve described in terms of control points and basis functions. The B-spline curve has been selected as the most stable format to represent all types of polynomial or rational parametric curves. With appropriate attribute values it is capable of representing single span or spline curves of explicit polynomial, rational, Bezier or B-spline type.

Interpretation of the data is as follows:

All weights shall be positive and the curve is given by

k+1 = number of control points

Pi = control points

wi = weights

d = degree

The knot array is an array of (k+d+2) real numbers [u-d … uk+1], such that for all indices j in [-d,k], uj <= uj+1. This array is obtained from the knot data list by repeating each multiple knot according to the multiplicity. N di, the ith normalized B-spline basis function of degree d, is defined on the subset [ui-d, … , ui+1] of this array.

Let L denote the number of distinct values among the d+k+2 knots in the knot array; L will be referred to as the ‘upper index on knots’. Let mj denote the multiplicity (number of repetitions) of the jth distinct knot. Then

All knot multiplicities except the first and the last shall be in the range 1 … degree; the first and last may have a maximum value of degree +

1. In evaluating the basis functions, a knot u of e.g. multiplicity 3 is interpreted as a string u, u, u, in the knot array. The B-spline curve has 3 special subtypes (Note: only 1, Bezier curve, included in this IFC release) where the knots and knot multiplicities are derived to provide simple default capabilities. Logical flag is provided to indicate whether the curve self intersects or not.

Figure 277 (from ISO 10303-42) illustrates a B-spline curve.

class IfcBuilding : public Ifc2x3::IfcSpatialStructureElement

Definition from ISO 6707-1:1989: Construction work that has the provision of shelter for its occupants or contents as one of its main purpose and is normally designed to stand permanently in one place. A building represents a structure that provides shelter for its occupants or contents and stands in one place. The building is also used to provide a basic element within the spatial structure hierarchy for the components of a building project (together with site, storey, and space). A building is (if specified) associated to a site. A building may span over several connected or disconnected buildings. Therefore building complex provides for a collection of buildings included in a site. A building can also be decomposed in (vertical) parts, where each part defines a building section. This is defined by the composition type attribute of the supertype IfcSpatialStructureElements which is interpreted as follow:

COMPLEX = building complex ELEMENT = building PARTIAL = building section

HISTORY New entity in IFC Release 1.0.

Property Set Use Definition The property sets relating to the IfcBuilding are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcBuilding are part of this IFC release:

Pset_BuildingCommon: common property set for all types of buildings Pset_BuildingWaterStorage: specific property set for buildings to capture the water supply requirements Pset_BuildingUse: specific property set for buildings to capture the current and anticipated real estate context. Pset_BuildingUseAdjacent: specific property set for buildings to capture the use information about the adjacent buildings.

Quantity Use Definition The quantities relating to the IfcBuilding are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, can be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement has to be provided.

Qto_BuildingBaseQuantities: base quantities for all building occurrences.

Spatial Structure Use Definition The IfcBuilding is used to build the spatial structure of a building (that serves as the primary project breakdown and is required to be hierarchical). The spatial structure elements are linked together by using the objectified relationship IfcRelAggregates. The IfcBuilding references them by its inverse relationships:

IfcBuilding.Decomposes referencing (IfcSite || IfcBuilding) by IfcRelAggregates.RelatingObject, If it refers to another instance of IfcBuilding, the referenced IfcBuilding needs to have a different and higher CompositionType, i.e. COMPLEX (if the other IfcBuilding has ELEMENT), or ELEMENT (if the other IfcBuilding has PARTIAL). IfcBuilding.IsDecomposedBy referencing (IfcBuilding || IfcBuildingStorey) by IfcRelAggregates.RelatedObjects. If it refers to another instance ofIfcBuilding, the referenced IfcBuilding needs to have a different and lower CompositionType, i.e. ELEMENT (if the other IfcBuilding has COMPLEX), or PARTIAL (if the other IfcBuilding has ELEMENT).

If there are building elements and/or other elements directly related to the IfcBuilding(like a curtain wall spanning several stories), they are associated with the IfcBuilding by using the objectified relationship IfcRelContainedInSpatialStructure. The IfcBuilding references them by its inverse relationship:

IfcBuilding.ContainsElements referencing any subtype of IfcProduct (with the exception of other spatial structure element) by IfcRelContainedInSpatialStructure.RelatedElements.

Figure 20 shows the IfcBuilding as part of the spatial structure. It also serves as the spatial container for building and other elements. NOTE Detailed requirements on mandatory element containment and placement structure relationships are given in view definitions and implementer agreements.

Figure 20 — Building composition

Systems, such as building service or electrical distribution systems, zonal systems, or structural analysis systems, relate to IfcBuilding by using the objectified relationship IfcRelServicesBuildings.

Attribute Use Definition

Figure 21 describes the heights and elevations of the IfcBuilding. It is used to provide the height above sea level of the project height datum for this building, that is, the internal height 0.00. The height 0.00 is often used as a building internal reference height and equal to the floor finish level of the ground floor.

base elevation of building provided by: IfcBuilding.ElevationOfRefHeight, it is usually the top of construction slab base elevation of terrain at the perimeter of the building provided by: IfcBuilding.ElevationOfTerrain, it is usually the minimum elevation is sloped terrain total height of building, also referred to as ridge height (top of roof structure, e.g the ridge against terrain): provided by BaseQuantity with Name=”TotalHeight” eaves height of building (base of roof structure, e.g the eaves against terrain): provided by BaseQuantity with Name=”EavesHeight”

Geometry Use Definitions The geometric representation of IfcBuilding is given by the IfcProductDefinitionShape and IfcLocalPlacement, allowing multiple geometric representation. Local Placement The local placement for IfcBuilding is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if relative placement is used) to the IfcSpatialStructureElement of type IfcSite, or of type IfcBuilding (e.g. to position a building relative to a building complex, or a building section to a building). If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations Currently, the use of a 2D ‘FootPrint’ representation of type ‘GeometricCurveSet’ and a 3D ‘Body’ representation of type ‘Brep’ is supported. Foot Print Representation The foot print representation of IfcBuilding is given by either a single 2D curve (such as IfcPolyline or IfcCompositeCurve), or by a list of 2D curves (in case of inner boundaries), if the building has an independent geometric representation. The representation identifier and type of this geometric representation of IfcBuilding is:

IfcShapeRepresentation.RepresentationIdentifier = ‘FootPrint’ IfcShapeRepresentation.RepresentationType = ‘GeometricCurveSet’

Body Representation The body (or solid model) geometric representation (if the building has an independent geometric representation) of IfcBuilding is defined using faceted B-Rep capabilities (with or without voids), based on the IfcFacetedBrep or on the IfcFacetedBrepWithVoids. The representation identifier and type of this representation of IfcBuilding is:

IfcShapeRepresentation.RepresentationIdentifier = ‘Body’ IfcShapeRepresentation.RepresentationType = ‘Brep’

Since the building shape is usually described by the exterior building elements, an independent shape representation shall only be given, if the building is exposed independently from its constituting elements.

Property Set Use Definition The properties relating to the IfcBuildingElement are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties. A detailed specification for individual property sets applicable is introduced at the level of subtypes of IfcBuildingElement. NOTE The applicable property sets are provided by an xml property set definition that includes multilingual translations for each property. The xml definition file format, psdXML, can be used to automatically configure the properties for each building element. Quantity Use Definition: The quantities relating to the IfcBuildingElement are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties. A detailed specification for individual quantities is introduced at the level of subtypes of IfcBuildingElement. NOTE The applicable element quantities are provided by an xml quantity definition that includes multilingual translations for each quantity. The xml definition file format, qdXML, can be used to automatically configure the quantities for each building element.

Geometry Use Definitions The geometric representation of any IfcBuildingElement is given by the IfcProductDefinitionShape and IfcLocalPlacement allowing multiple geometric representations. Local Placement The local placement for any IfcBuildingElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations. Further constraints are defined at the level of its subtypes. Geometric Representations An IfcBuildingElement can be represented by one or several geometric representations. The following representation identifiers are used for building elements ‘Box’, ‘Axis’, ‘FootPrint’, ‘Surface’, and ‘Body’. A detailed specification is introduced at the level of subtypes. NOTE Some subtypes of IfcBuildingElement may exclude one or several geometric representation types, e.g. standard case elements, such as IfcWallStandardCase, do not allow the use of ‘SurfaceModel’, ‘Brep’, ‘AdvancedBrep’, and ‘MappedRepresentation’. In addition view definitions and implementer agreements may restrict the use of geometric representation types, e.g. the use of ‘AdvancedBrep’. Box Representation Any IfcBuildingElement may be represented as a bounding box, which shows the maximum extend of the body within the coordinated system established by the IfcLocalPlacement. The bounding box representation is the simplest geometric representation available. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Box’ RepresentationType : ‘BoundingBox’

As shown in Figure 22, the bounding box representation is given by an IfcShapeRepresentation that includes a single item, an IfcBoundingBox.

Figure 22 — Building element box representation

Axis Representation Some IfcBuildingElement may be represented by an axis as an abstract geometric representation. See each subtype for specific guidance. The following attribute values for the IfcShapeRepresentation holding this geometric representation are used:

RepresentationIdentifier : ‘Axis’ RepresentationType : ‘Curve2D’, ‘Curve3D’

Surface Representation Some IfcBuildingElement may be represented by an surface as an abstract geometric representation. See each subtype for specific guidance. The following attribute values for the IfcShapeRepresentation holding this geometric representation are used:

RepresentationIdentifier : ‘Surface’ RepresentationType : ‘Surface2D’, ‘Surface3D’

FootPrint Representation Any IfcBuildingElement may be represented by a footprint as a specific floor plan geometric representation. See each subtype for specific guidance. The following attribute values for the IfcShapeRepresentation holding this geometric representation are used:

RepresentationIdentifier : ‘FootPrint’ RepresentationType : ‘GeometricCurveSet’, ‘Annotation2D’

Body Representation The body representation of any IfcBuildingElement can have the following representation types: ‘SurfaceModel’, ‘Brep’, ‘AdvancedBrep’, and ‘MappedRepresentation’. Other representation types might be specified at the level of subtypes. SurfaceModel Representation Type Any IfcBuildingElement (so far no further constraints are defined at the level of its subtypes) may be represented as a single or multiple surface models, based on either shell or face based models. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SurfaceModel’

In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape.

As shown in Figure 23, the surface model representation is given by an IfcShapeRepresentation, which includes a single item which is either:

IfcShellBasedSurfaceModel, or IfcFaceBasedSurfaceModel.

Figure 23 — Building element surface model representation

Brep Representation Type Any IfcBuildingElement (so far no further constraints are defined at the level of its subtypes) may be represented as a single or multiple Boundary Representation elements (which are restricted to faceted Brep with or without voids). The Brep representation allows for the representation of complex element shape. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Brep’

In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape. As shown in Figure 24, the Brep representation is given by an IfcShapeRepresentation, which includes one or more items, all of type IfcFacetedBrep.

Figure 24 — Building element body boundary representation

AdvancedBrep Representation Type An IfcBuildingElement (so far no further constraints are defined at the level of its subtypes or by view definitions) may be represented as a single or multiple Boundary Representation elements (which are based on advanced surfaces, usually refered to as NURBS surfaces). The AdvancedBrep representation allows for the representation of complex free-form element shape. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘AdvancedBrep’

In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape. MappedRepresentation Representation Type Any IfcBuildingElement (so far no further constraints are defined at the level of its subtypes) may be represented using the MappedRepresentation. This shall be supported as it allows for reusing the geometry definition of a type at all occurrences of the same type. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘MappedRepresentation’

The same constraints, as given for ‘SurfaceModel’, ‘Brep’, and ‘AdvancedBrep’ geometric representation, shall apply to the MappedRepresentation of the IfcRepresentationMap.

class IfcBuildingElementProxy : public Ifc2x3::IfcBuildingElement

Definition from IAI: The IfcBuildingElementProxy is a proxy definition that provides the same functionality as an IfcBuildingElement, but without having a predefined meaning of the special type of building element, it represents. Proxies can also be used as spatial place holders or provisions, that maybe later replaced by special types of elements. One use of the proxy object is a provision for voids, i.e. where a particular volume of space is requested by some engineering function that might later be accepted or rejected and if accepted potentially transformed into a void within a building element, like a wall opening, or a slab opening. The provision for voids is exchanged as an IfcBuildingElementProxy with the PredefinedType = ProvisionForVoid. Other usages of IfcBuildingElementProxy include:

The IfcBuildingElementProxy can be used to exchange special types of building elements for which the current IFC Release does not yet provide a semantic definition. The IfcBuildingElementProxy can also be used to represent building elements for which the participating applications can not provide additional semantic classification.

HISTORY New entity in IFC Release 2x. IFC2x4 CHANGE The attribute CompositionType has been replaced by PredefinedType, being a superset of the enumerators. Type Use Definition The IfcBuildingElementProxy defines the occuurence of any building element, common information about the types (or styles) is handled by IfcBuildingElementProxyType. The IfcBuildingElementProxyType (if present) may establish the common type name, usage (or predefined) type, common material, common set of properties and common shape representations (using IfcRepresentationMap). The IfcBuildingElementProxyType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.

NOTE The IfcBuildingElementProxyType can be used to share common information among many occurrences of the same proxy without establishing a particular semantic meaning of the type.

If no IfcBuildingElementProxyType is attached (i.e. if only occurrence information is given) the PredefinedType should be provided. If set to .USERDEFINED. a user defined value can be provided by the ObjectType attribute. Material Use Definition The material of the IfcBuildingElementProxy is defined by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Note It is illegal to assign an IfcMaterial to an IfcBuildingElementProxy with the PredefinedType = ProvisionForVoid. Material information can also be given at the IfcBuildingElementProxyType, defining the common attribute data for all occurrences of the same type.It is then accessible by the inverse IsTypedBy relationship pointing to IfcBuildingElementProxyType.HasAssociations and via IfcRelAssociatesMaterial.RelatingMaterial to IfcMaterial. If both are given, then the material directly assigned to IfcBuildingElementProxy overrides the material assigned to IfcBuildingElementProxyType. Property Set Use Definition: The property sets relating to the IfcBuildingElementProxy are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcBuildingElementProxy are part of this IFC release:

Pset_BuildingElementProxyCommon: common property set for all occurrences of building element proxies. Pset_BuildingElementProxyProvisionForVoid: specific property set for all occurrences of building element proxy with the PredefinedType: PROVISIONFORVOID.

Property sets can also be given at the IfcBuildingElementProxyType, defining the common property data for all occurrences of the same type.It is then accessible by the inverse IsTypedBy relationship pointing to IfcBuildingElementProxyType.HasPropertySets. If both are given, then the properties directly assigned to IfcBuildingElementProxy overrides the properties assigned to IfcBuildingElementProxyType. Containment Use Definition The IfcBuildingElementProxy, as any subtype of IfcBuildingElement, may participate in two different containment relationships. The first (and in most implementation scenarios mandatory) relationship is the hierachical spatial containment, the second (optional) relationship is the aggregation within anelement assembly.

The IfcBuildingElementProxy is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, refering to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes ofIfcSpatialStructureElement are valid spatial containers, with IfcBuildingStorey being the default container. The IfcBuildingElementProxy may be aggregated into an element assembly using the objectified relationship IfcRelAggregates, refering to it by its inverse attribute SELF\IfcObjectDefinition.Decomposes. Any subtype of IfcElement can be an element assembly, with IfcElementAssembly as a special focus subtype. In this case it should not be additionally contained in the project spatial hierarchy, i.e.SELF\IfcElement.ContainedInStructure should be NIL.

Geometry Use Definition The geometric representation of IfcBuildingElementProxy is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are: Local Placement The local placement for any IfcBuildingElementProxy is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations. The local placement can be given relativly.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement, which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representation Currently, the ‘FootPrint’, ‘Body’, and ‘Box’ representations are supported. The ‘Box’ representation includes the representation type ‘BoundingBox’ and is explained at IfcBuildingElement. FootPrint Representation Any building element proxy may be represented by a geometric curve set, given by a collection of 2D points and curves. The foot pring geometric representation of IfcBuildingElementProxy is defined using the ‘FootPrint’ representation.

RepresentationIdentifier: ‘FootPrint’ RepresentationType: ‘GeometricCurveSet’, ‘Annotation2D’

Body Representation The body representation of IfcBuildingElementProxy can be represented using the representation types ‘GeometricSet’, ‘SweptSolid’, ‘CSG’ ‘SurfaceModel’, ‘Brep’, and ‘MappedRepresentation’. The representation types ‘SurfaceModel’, ‘Brep’, and ‘MappedRepresentation’ are explained at IfcBuildingElement. GeometricSet Representation Type Any building element proxy may be represented by a geometric set, given by a collection of 2D and 3D points, curves, and surfaces. It represents the body of the proxy object, when no topological structure is available. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier: ‘Body’ RepresentationType: ‘GeometricSet’

SweptSolid Representation Type Any building element proxy may be represented by swept solid geometry (either by extrusion or by revolution). The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier: ‘Body’ RepresentationType: ‘SweptSolid’

No further restrictions (e.g., for the profile or extrusion direction) are defined at this level. A single or multiple swept area solid(s) can be the Items of the IfcShapeRepresentation. CSG Representation Type Any building element proxy may be represented by a CSG primitive or CSG tree. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier: ‘Body’ RepresentationType: ‘CSG’

No further restrictions (e.g., for the depths of the CSG tree) are defined at this level.

NOTE The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A building element proxy type is used to define the common properties of a certain type of a building element proxy that may be applied to many instances of thattype to assign a specific style. Building element proxy typesmay be exchanged without being already assigned to occurrences.

NOTE Although an building element proxy does not have a predefined ontological meaning the provision of a type may be helpful in sharing information among multiple occurrences. Applications that provide type information for element types not yet included in the current IFC specification can use the IfcBuildingElementProxyType to exchange such types.

The occurrences of the IfcBuildingElementProxyType are represented by instances of IfcBuildingElementProxy.

Definition from IAI: The element type (IfcBuildingElementType) defines a list of commonly shared property set definitions of a building element and an optional set of product representations. It is used to define an element specification (i.e. the specific product information, that is common to all occurrences of that product type).

NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A building element type is used to define the common properties of a certain type of a building element that may be applied to many instances of that feature type to assign a specific style. Building element types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

class IfcBuildingStorey : public Ifc2x3::IfcSpatialStructureElement

The building storey has an elevation and typically represents a (nearly) horizontal aggregation of spaces that are vertically bound. A storey is (if specified) associated to a building. A storey may span over several connected storeys. Therefore storey complex provides for a collection of storeys included in a building. A storey can also be decomposed in (horizontical) parts, where each part defines a partial storey. This is defihned by the composition type attribute of the supertype IfcSpatialStructureElements which is interpreted as follow:

COMPLEX = building storey complex ELEMENT = building storey PARTIAL = partial building storey

EXAMPLE In split level houses, a storey is split into two or more partial storeys, each with a different elevation. It can be handled by defining a storey, which includes two or more partial storeys with the individual elevations. HISTORY New entity in IFC Release 1.0

Property Set Use Definition The property sets relating to the IfcBuildingStorey are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcBuildingStorey are part of this IFC release:

Pset_BuildingStoreyCommon: common property set for all types of building stories

Quantity Use Definition The quantities relating to the IfcBuildingStorey are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, can be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement has to be provided.

Qto_BuildingStoreyBaseQuantities: base quantities for all building storey occurrences.

Spatial Structure Use Definition The IfcBuildingStorey is used to build the spatial structure of a building (that serves as the primary project breakdown and is required to be hierarchical). The spatial structure elements are linked together by using the objectified relationship IfcRelAggregates. The IfcBuildingStoreyreferences them by its inverse relationships:

IfcBuildingStorey.Decomposes referencing (IfcBuilding || IfcBuildingStorey) by IfcRelAggregates.RelatingObject, If it refers to another instance ofIfcBuildingStorey, the referenced IfcBuildingStorey needs to have a different and higher CompositionType, i.e. COMPLEX (if the other IfcBuildingStorey has ELEMENT), or ELEMENT (if the other IfcBuildingStorey has PARTIAL). IfcBuildingStorey.IsDecomposedBy referencing (IfcBuildingStorey || IfcSpace) by IfcRelAggregates.RelatedObjects. If it refers to another instance ofIfcBuildingStorey, the referenced IfcBuildingStorey needs to have a different and lower CompositionType, i.e. ELEMENT (if the other IfcBuildingStorey has COMPLEX), or PARTIAL (if the other IfcBuildingStorey has ELEMENT).

If there are building elements and/or other elements directly related to the IfcBuildingStorey (like most building elements, such as walls, columns, etc.), they are associated with the IfcBuildingStorey by using the objectified relationship IfcRelContainedInSpatialStructure. The IfcBuildingStorey references them by its inverse relationship:

IfcBuildingStorey.ContainsElements referencing any subtype of IfcProduct (with the exception of other spatial structure element) by IfcRelContainedInSpatialStructure.RelatedElements.

Figure 25 shows the IfcBuildingStorey as part of the spatial structure. It also serves as the spatial container for building and other elements. NOTE Detailed requirements on mandatory element containment and placement structure relationships are given in view definitions and implementer agreements.

Figure 25 — Building storey composition

Elements can also be referenced in an IfcBuildingStorey, for example, if they span through several storeys. This is expressed by using the objectified relationship IfcRelReferencedInSpatialStructure. Systems, such as building service or electrical distribution systems, zonal systems, or structural analysis systems, relate to IfcBuildingStorey by using the objectified relationship IfcRelServicesBuildings.

Attribute Use Definition

Figure 26 describes the heights and elevations of the IfcBuildingStorey.

elevation of storey provided by: IfcBuildingStorey.Elevation as a local height value relative to IfcBuilding.ElevationOfRefHeight, it is usually the top of construction slab net height of storey, also referred to as total height or system height (top of construction slab to top of construction slab above): provided by BaseQuantity with Name=”GrossHeight” net height of storey (top of construction slab to bottom of construction slab above): provided by BaseQuantity with Name=”NetHeight”

Figure 26 — Building storey elevations

Geometry Use Definitions The geometric representation of IfcBuildingStorey is given by the IfcProductDefinitionShape and IfcLocalPlacement, allowing multiple geometric representation. Local Placement The local placement for IfcBuildingStorey is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if relative placement is used) to the IfcSpatialStructureElement of type IfcBuilding, or of type IfcBuildingStorey (e.g. to position a building storey relative to a building storey complex, or a partial building storey to a building storey). If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations Currently, the use of a 2D ‘FootPrint’ representation of type ‘GeometricCurveSet’ and a 3D ‘Body’ representation of type ‘Brep’ is supported.

NOTE The independent geometric representation of IfcBuildingStorey may not be required or allowed in certain view definitions. In those cases only the contained elements and spaces have an independent geometric representation.

Foot Print Representation The foot print representation of IfcBuildingStorey is given by either a single 2D curve (such as IfcPolyline or IfcCompositeCurve), or by a list of 2D curves (in case of inner boundaries), if the building storey has an independent geometric representation. The representation identifier and type of this geometric representation of IfcBuildingStorey is:

IfcShapeRepresentation.RepresentationIdentifier = ‘FootPrint’ IfcShapeRepresentation.RepresentationType = ‘GeometricCurveSet’

Body Representation The body (or solid model) geometric representation (if the building storey has an independent geometric representation) of IfcBuildingStorey is defined using faceted B-Rep capabilities (with or without voids), based on the IfcFacetedBrep or on the IfcFacetedBrepWithVoids. The representation identifier and type of this representation of IfcBuildingStorey is:

IfcShapeRepresentation.RepresentationIdentifier = ‘Body’ IfcShapeRepresentation.RepresentationType = ‘Brep’

Since the building storey shape is usually described by the exterior building elements, an independent shape representation shall only be given, if the building storey is exposed independently from its constituting elements.

Definition from ISO/CD 10303-42:1992: A Cartesian transformation operator defines a geometric transformation composed of translation, rotation, mirroring and uniform scaling. The list of normalized vectors u defines the columns of an orthogonal matrix T. These vectors are computed, by the base axis function, from the direction attributes axis1, axis2 and, in Cartesian transformation operator 3d, axis3. If |T|= -1, the transformation includes mirroring. The local origin point A, the scale value S and the matrix T together define a transformation.

The transformation for a point with position vector P is defined by

P -> A + STP

The transformation for a direction d is defined by

d -> Td

The transformation for a vector with orientation d and magnitude k is defined by

d -> Td, and

k -> Sk

For those entities whose attributes include an axis2 placement, the transformation is applied, after the derivation, to the derived attributes p defining the placement coordinate directions. For a transformed surface, the direction of the surface normal at any point is obtained by transforming the normal, at the corresponding point, to the original surface. For geometric entities with attributes (such as the radius of a circle) which have the dimensionality of length, the values will be multiplied by S.

For curves on surface the p curve.reference to curve will be unaffected by any transformation. The Cartesian transformation operator shall only be applied to geometry defined in a consistent system of units with the same units on each axis. With all optional attributes omitted, the transformation defaults to the identity transformation. The Cartesian transformation operator shall only be instantiated as one of its subtypes.

The profile IfcCenterLineProfileDef defines an arbitrary two-dimensional open, not self intersecting profile for the use within the swept solid geometry. It is given by an area defined by applying a constant thickness to a centerline, generating an area from which the solid can be constructed.

Among else, IfcCenterLineProfileDef is used to model cold-formed steel or aluminium sections (Sigma, Zeta, Omega, and similar sections which are not covered by subtypes of IfcParameterizedProfileDef). However, since IfcCenterLineProfileDef does not provide shape parameters except for the thickness, there is generally a need to further specify the profile definition by means of

the name, external reference to a document or library, profile properties,

or a combination of them. See IfcProfileDef for guidance on external references for profiles.

Informal proposition:

The Curve has to be an open curve. The Curve has to be a non-intersecting curve.

Figure 311 illustrates the center line profile definition. The Curve is defined in the underlying coordinate system. The underlying coordinate system is defined by the swept surface that uses the profile definition. It is the xy plane of:

struct IfcChangeActionEnum

Public Types

enum Value

IfcChangeActionEnum identifies the type of change that might have occurred to the object during the last session (for example, added, modified, deleted). This information is required in a partial model exchange scenario so that an application or model server will know how an object might have been affected by the previous application. Valid enumerations are:

NOCHANGE: Object has not been modified.

MODIFIED: A modification to the object has been made by the user and application defined by the LastModifyingUser and LastModifyingApplication respectively.

ADDED: The object has been created by the user and application defined by the OwningUser and OwningApplication respectively.

DELETED: The object has been deleted by the user and application defined by the LastModifyingUser and LastModifyingApplication respectively.

NOTDEFINED: The change action is not known or has not been defined.

Consider Application A will create an IFC dataset that it wants to publish to others for modification and have the ability to subsequently merge these changes back into the original model. Before publication, it may want to set the IfcChangeActionEnum to NOCHANGE to establish a baseline so that other application changes can be easily identified. Application B then receives this IFC dataset and adds a new object and sets IfcChangeActionEnum to ADDED with Application B defined as the OwningApplication. Application B then modifies an existing object and (re)defines the LastModifiedDate to the time of the modification, LastModifyingUser to the IfcPersonAndOrganization making the change, and sets the LastModifyingApplication to Application B. When Application A receives this modified dataset, it can determine which objects have been added and modified by Application B and either merge or reject these changes as necessary. Consequently, the intent is that an application only modifies the value of IfcChangeActionEnum when it does something to the object, with the further intent that a model server is responsible for clearing the IfcChangeActionEnum back to NOCHANGE when it is ready to be republished.

class IfcClassification : public IfcUtil::IfcBaseEntity

An IfcClassification is used for the arrangement of objects into a class or category according to a common purpose or their possession of common characteristics. A classification in the sense of IfcClassification is taxonomy, or taxonomic scheme, arranged in a hierarchical structure. A category of objects relates to other categories in a generalization-specialization relationship. Therefore the classification items in an classification are organized in a tree structure.

HISTORY New class in IFC Release 1.5. Modified in IFC 2x.

IFC 2x4 CHANGE Attribute Edition made optional. Attributes: PublicationLocation, Description and ReferenceTokens added. Inverse attribute HasClassificationReferences added.

Classification use definitions IfcClassification identifies the classification system or source from which a classification notation is derived. Each classification reference or classification item, belonging to a single classification system, shall reference a single instance of IfcClassification. Therefore, each particular classification system or source used should have only one IfcClassification instance. However, because multiple classification is allowed, there may be many IfcClassification objects used, each identifying a different classification system or source.

A classification system declared may be either formally published (such as Omniclass, Uniclass, Masterformat, or DIN) or it may be a locally defined method of classifiying information. There are two methods to define a classification system within an IFC dataset:

Including the classification system structure within the dataset: Here a hierarchical tree of IfcClassificationItem’s is included that defines the classification system including the relationship between the classification items. An IfcClassificationNotation is used to classify an object. Referencing the classification system by a classification key or id: Here the IfcClassificationReference is used to assign a classification id or key to each classified object.

An IfcClassificationReference is a reference into a classification system or source (see IfcClassification) for a specific classification key (or notation).

The inherited attributes have the following meaning:

Identification: holds the key provided for a specific references to classification items (or tables). Name: allows for a human interpretable designation of a classification notation. Location: optionally holds a direct URI link into the classification system (or source) to hyperlink the classification key.

The IfcClassificationReference can either be assigned directly to the IfcClassification, such as if no classification hierarchy has to be included, or it references the parent classification notation, if the fully classification hierarchy is included in the data set. The attribute ReferencedSource then holds the following information (choice by IfcClassificationReferenceSelect):

being of type IfcClassification: direct reference to the classification system (with meta information provided), used for highest level of classification notations, or if the classification notation hierarchy is not relevant, being of type IfcClassificationReference: reference to the parent classification notation within the classification hierarchy.

HISTORY New entity in IFC 2x.

IFC2x4 CHANGE The attribute Description and inverse attribute HasReferences are added. The attribute Identification has been renamed from ItemReference.

Use definitions The IfcClassificationReference can be used to only assign classification keys to objects, or to hold a fully classification hierarchy. The first is refered to as “lightweight classification”, and the second as “full classification”

The IfcClassificationReference can be used as a form of ‘lightweight’ classification through the ‘Identification’ attribute inherited from the abstract IfcExternalReference class. In this case, the ‘Identification’ could take (for instance) the Uniclass notation “L6814” which, if the classification was well understood by all parties and was known to be taken from a particular classification source, would be sufficient. The Name attribute could be the title “Tanking”. This would remove the need for the overhead of the more complete classification structure of the model.

class IfcClosedShell : public Ifc2x3::IfcConnectedFaceSet

Definition from ISO/CD 10303-42:1992: A closed shell is a shell of the dimensionality 2 which typically serves as a bound for a region in R3. A closed shell has no boundary, and has non-zero finite extent. If the shell has a domain with coordinate space R3, it divides that space into two connected regions, one finite and the other infinite. In this case, the topological normal of the shell is defined as being directed from the finite to the infinite region.

The shell is represented by a collection of faces. The domain of the shell, if present, contains all those faces, together with their bounds. Associated with each face in the shell is a logical value which indicates whether the face normal agrees with (TRUE) or is opposed to (FALSE) the shell normal. The logical value can be applied directly as a BOOLEAN attribute of an oriented face, or be defaulted to TRUE if the shell boundary attribute member is a face without the orientation attribute.

The combinatorial restrictions on closed shells and geometrical restrictions on their domains are designed to ensure that any domain associated with a closed shell is a closed, orientable manifold. The domain of a closed shell, if present, is a connected, closed, oriented 2-manifold. It is always topologically equivalent to an H-fold torus for some H ³ 0. The number H is referred to as the surface genus of the shell. If a shell of genus H has a domain within coordinate space R3, then the finite region of space inside it is topologically equivalent to a solid ball with H tunnels drilled through it. The Euler equation (7) applies with B=0, because in this case there are no holes. As in the case of open shells, the surface genus H may not be known a priori, but shall be an integer ³ 0. Thus a necessary, but not sufficient, condition for a well-formed closed shell is the following:

In the current IFC Release only poly loops (IfcPolyLoop) are defined for bounds of face bound (IfcFaceBound). This will allow for faceted B-rep only.

NOTE: Corresponding ISO 10303 entity: closed_shell, please refer to ISO/IS 10303-42:1994, p.149 for the final definition of the formal standard.

class IfcColourRgb : public Ifc2x3::IfcColourSpecification

Definition from ISO/CD 10303-46:1992: A colour rgb as a subtype of colour specifications is defined by three colour component values for red, green, and blue in the RGB colour model.

NOTE In contrary to the usual value range of colour components being integer from 0…255, the definition from ISO10303-46 defines the colour components as real from 0.0 … 1.0. Applications need to execute this conversion before populating the colour RGB values.

class IfcColumn : public Ifc2x3::IfcBuildingElement

Definition from ISO 6707-1:1989: Structural member of slender form, usually vertical, that transmits to its base the forces, primarily in compression, that are applied to it. <An IfcColumn is a vertical structural member which often is aligned with a structural grid intersection. It represents a vertical, or nearly vertical, structural member that transmits, through compression, the weight of the structure above to other structural elements below. It represents such a member from an architectural point of view. It is not required to be load bearing. NOTE The representation of a column in a structural analysis model is provided by IfcStructuralCurveMember being part of an IfcStructuralAnalysisModel.

NOTE For any longitudial structural member, not constrained to be predominately horizontal nor vertical, or where this semantic information is irrelevant, the entity IfcMember exists. The IFC specification provides two entities for column occurrences:

IfcColumnStandardCase used for all occurrences of columns, tthat have a profile defined that is swept along a directrix. The profile might be changed uniformly by a taper definition along the directrix. The profile parameter and its cardinal point of insertion can be fully described by the IfcMaterialProfileSetUsage. These beams are always represented geometricly by an ‘Axis’ and a ‘SweptSolid’ or ‘AdvancedSweptSolid’ shape representation (or by a ‘Clipping’ geometry based on the swept solid), if a 3D geometric representation is assigned. In addition they have to have a corresponding IfcMaterialProfileSetUsage assigned. NOTE View definitions and implementer agreements may further constrain the applicable geometry types, e.g. by excluding tapering from an IfcColumnStandardCase implementation.

IfcColumn used for all other occurrences of columns, particularly for columns with changing profile sizes along the extrusion, or columns defined by non-linear extrusion, or columns having only ‘Brep’, or ‘SurfaceModel’ geometry.

HISTORY New entity in IFC Release 1.0

Type Use Definition IfcColumn defines the occuurence of any column, common information about column types (or styles) is handled by IfcColumnType. The IfcColumnType (if present) may establish the commontype name, usage (or predefined) type, common material layer set, common set of properties and common shape representations (using IfcRepresentationMap). The IfcColumnType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute. If no IfcColumnType is attached(i.e. if only occurrence information is given) the PredefinedType should be provided. If set to .USERDEFINED. a user defined value can be provided by the ObjectType attribute. Material Use Definition The material of the IfcColumn is defined by the IfcMaterialProfileSet or as fallback by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Note: It is illegal to assign an IfcMaterialProfileSetUsage to an IfcColumn. Only the subtype IfcColumnStandardCase supports this concept. Material information can also be given at the IfcColumnType, defining the common attribute data for all occurrences of the same type.It is then accessible by the inverse IsTypedBy relationship pointing to IfcColumnType.HasAssociations and via IfcRelAssociatesMaterial.RelatingMaterial to IfcMaterialProfileSet or IfcMaterial. If both are given, then the material directly assigned to IfcColumn overrides the material assigned to IfcColumnType. Property Set Use Definition: The property sets relating to the IfcColumn are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcColumn are part of this IFC release:

Pset_ColumnCommon: common property set for all column occurrences

Property sets can also be given at the IfcColumnType, defining the common property data for all occurrences of the same type.It is then accessible by the inverse IsTypedBy relationship pointing to IfcColumnType.HasPropertySets. If both are given, then the properties directly assigned to IfcColumn overrides the properties assigned to IfcColumnType. Quantity Use Definition: The quantities relating to the IfcColumn are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.MethodOfMeasurement = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement. Quanties shall be never assigned to the IfcColumnType.

Qto_ColumnBaseQuantities: base quantities for all column occurrences.

Containment Use Definition The IfcColumn, as any subtype of IfcBuildingElement, may participate in two different containment relationships. The first (and in most implementation scenarios mandatory) relationship is the hierachical spatial containment, the second (optional) relationship is the aggregation within anelement assembly.

The IfcColumn, is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, refering to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes ofIfcSpatialStructureElement are valid spatial containers, with IfcBuildingStorey being the default container. The IfcColumn, may be aggregated into an element assembly using the objectified relationship IfcRelAggregates, refering to it by its inverse attribute SELF\IfcObjectDefinition.Decomposes. Any subtype of IfcElement can be an element assembly, with IfcElementAssembly as a special focus subtype. In this case it should not be additionally contained in the project spatial hierarchy, i.e.SELF\IfcElement.ContainedInStructure should be NIL.

Geometry Use Definition The geometric representation of IfcColumn is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are: Local Placement The local placement for IfcColumn is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement, which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representation Currently, the ‘Axis’, ‘Body’, and ‘Box’ representations are supported. The ‘Box’ representation includes the representation type ‘BoundingBox’ and is explained at IfcBuildingElement. Axis Representation The axis geometric representation of IfcColumn is defined using the ‘Axis’ representation. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Axis’ RepresentationType : ‘Curve2D’, ‘Curve3D’

The axis representation can be used to represent the system length of a column that may extent the body length of the column. Body Representation The body representation of IfcColumn can be represented using the representation types ‘SweptSolid’, ‘Clipping’, ‘AdvancedSweptSolid’, ‘MappedRepresentation’, ‘SurfaceModel’, and ‘Brep’. The representation types ‘SurfaceModel’ and ‘Brep’ are explained at IfcBuildingElement. SweptSolid Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SweptSolid’

The following additional constraints apply to the ‘SweptSolid’ representation:

Solid: IfcExtrudedAreaSolid, IfcRevolvedAreaSolid shall be supported Profile: all subtypes of IfcProfileDef (with exception of IfcArbitraryOpenProfileDef) Extrusion:All extrusion directions shall be supported

Figure 81 illustrates a ‘SweptSolid’ geometric representation. There are no restrictions or conventions on how to use the local placement (black), solid of extrusion placement (red) and profile placement (green).

Figure 81 — Column swept solid

Figure 82 illustrates use of a special profile type (here IfcIShapeProfileDef) for the definition of the IfcExtrudedAreaSolid.

Figure 82 — Column extrusion of I-Shape

Clipping Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Clipping’

The following constraints apply to the advanced representation:

Solid: see ‘SweptSolid’ geometric representation Profile: see ‘SweptSolid’ geometric representation Extrusion: see ‘SweptSolid’ geometric representation Boolean result: The IfcBooleanClippingResult shall be supported, allowing for Boolean differences between the swept solid (here IfcExtrudedAreaSolid) and one or several IfcHalfSpaceSolid.

Figure 83 illustrates a ‘Clipping’ geometric representation with use of IfcBooleanClippingResult between an IfcExtrudedAreaSolid and an IfcHalfSpaceSolid to create a clipped body.

Figure 83 — Column clipping

AdvancedSweptSolid Representation Type The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘AdvancedSweptSolid’

The following additional constraints apply to the ‘AdvancedSweptSolid’ representation type:

Solid: IfcSurfaceCurveSweptAreaSolid, IfcFixedReferenceSweptAreaSolid, IfcExtrudedAreaSolidTapered, IfcRevolvedAreaSolidTapered shall be supported. NOTE View definitions and implementer agreements can further constrain the allowed swept solid types.

Profile: see ‘SweptSolid’ geometric representation Extrusion:not applicable

MappedRepresentation Representation Type The ‘MappedRepresentation’ representation type is supported as it allows for reusing the geometry definition of the beam type at all occurrences of the same type. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘MappedRepresentation’

The same constraints, as given for the ‘SweptSolid’, ‘Clipping’, ‘AdvancedSweptSolid’, ‘SurfaceModel’ and ‘Bre’ geometric representation, shall apply to the MappedRepresentation of the IfcRepresentationMap.

Definition from IAI: The element type IfcColumnType defines commonly shared information for occurrences of columns. The set of shared information may include:

common properties within shared property sets common material information common profile definitions common shape representations

It is used to define a column specification, or column style (i.e. the specific product information that is common to all occurrences of that column type). Column types may be exchanged without being already assigned to occurrences. Occurrences of the IfcColumnType within building models are represented by instances of IfcColumnStandardCase if the IfcColumnType has a single associated IfcMaterialProfileSet; otherwise they are represented by instances of IfcColumn. Occurrences of the IfcColumnType within structural analysis models are represented by instances of IfcStructuralCurveMember, or its applicable subtypes. HISTORY New entity in Release IFC2x Edition 2. Material Use Definition The material of the IfcColumnType is defined by the IfcMaterialProfileSet or as fall back by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Note: It is illegal to assign an IfcMaterial to an IfcColumnType, if there is at least one occurrences of IfcColumnStandardCase for this type. Property Set Use Definition: The shared property sets relating to the IfcColumnType are defined by the IfcPropertySet and are attached by the HasPropertySets attribute. The following property set definitions specific to the IfcColumnType are part of this IFC release: NOTE There is no differentiation between properties within the property set that are only assignable to IfcColumnType and those that are only assignable to IfcColumn. If the same property is assigned to the IfcColumnType and the IfcColumn being an occurrence of the IfcColumnType, then the occurrence property overrides the type property.

Pset_ColumnCommon: common property set for all column types.

Profile Use Definition: The shared profile definition is defined by assigning an IfcMaterialProfileSet (see material use definition above). The IfcMaterialProfile refers to the subtype of IfcProfileDef that is the common profile for all column occurrence, if used. It is only applicable if the IfcColumnType has only occurrences of type IfcColumnStandardCase (see definition of IfcColumnStandardCase for further information). NOTE The attribute ProfileName of the IfcProfileDef subtype, referenced in IfcMaterialProfile should contain a standardized profile name according to local standards. However, an additional geometric representation of the profile is necessary (e.g. as IfcExtrudedAreaSolid). An importing application is allowed to check for the existence of the profile name: in case of identifying it as a standardized name, the corresponding profile geometry and possibly other cross sectional properties can be read from a library. Otherwise the geometric representation and possible non geometric IfcProfileProperties have to be used. Geometry Use Definition: The IfcColumnType may define the shared geometric representation for all column occurrences. The RepresentationMaps attribute refers to a list of IfcRepresentationMap’s, that allow for multiple geometric representations (e.g. with IfcShaperepresentation’s having an RepresentationIdentifier ‘Box’, ‘Axis’, or ‘Body’). It is only applicable if the IfcColumnType has only occurrences of type IfcColumn (See geometric use definition of IfcColumn for further information). NOTE If the IfcColumnType has an associated IfcMaterialProfileSet, then no shared geometric representation shall be provided. NOTE The product shape representations are defined as RepresentationMaps (attribute of the supertype IfcTypeProduct), which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[n] being an IfcMappedItem. See IfcTypeProduct for further information. NOTE The values of attributes RepresentationIdentifier and RepresentationType of IfcShapeRepresentation are restricted in the same way as those for IfcColumn and IfcColumnStandardCase

class IfcCompositeCurve : public Ifc2x3::IfcBoundedCurve

Definition from ISO/CD 10303-42:1992: A composite curve is a collection of curves joined end-to-end. The individual segments of the curve are themselves defined as composite curve segments. The parameterization of the composite curve is an accumulation of the parametric ranges of the referenced bounded curves. The first segment is parameterized from 0 to l1 and for i ≤ 2, the ith segment is parameterized from:

where lk is the parametric length (i.e., difference between maximum and minimum parameter values) of the curve underlying the kth segment.

Let T denote the parameter for the composite curve. Then, if the ith segment is not a reparameterised composite curve segment, T is related to the parameter ti; ti0 ≤ ti ≤ ti1; for the ith segment by the equation:

if Segments[i].SameSense = TRUE;

or by the equation:

if Segments[i].SameSense = FALSE;

If the segments[i] is of type reparameterised composite curve segment,

where τ is defined at reparameterized composite curve segment (see IfcReparameterizedCompositeCurveSegment).

Figure 279 illustrates an example of a composite curve.

Figure 279 — Composite curve

Consider an IfcCompositeCurve having line segment and an arc segment. The line should be parameterized:

IfcPolyline with start= 0.,0. end= 0.,1., SameSense= TRUE, parametric length = 1.

The arch should be parameterized:

IfcTrimmedCurve with start= 180’, end= 90’, SameSense= FALSE, parametric length = 90.

Then the parameterization of the composite curve is:

IfcCompositeCurve with 0. ≤ T ≤ 1. (line segment) and 1. ≤ T ≤ 91. (arc segment), parametric length = 91.

NOTE Corresponding ISO 10303 entity: composite_curve, please refer to ISO/IS 10303-42:1994, p. 56 for the final definition of the formal standard. The WR2 is added to ensure consistent Dim at all segments.

Figure 314 illustrates the composite profile definition. The IfcCompositeProfileDef does not define an own position coordinate system, it is directly defined in the underlying coordinate system. The underlying coordinate system is defined by the swept surface or swept area solid that uses the profile definition. It is the xy plane of either:

IfcSweptSurface.Position IfcSweptAreaSolid.Position

Or in case of sectioned spines it is the xy plane of each list member of IfcSectionedSpine.CrossSectionPositions. The IfcCompositeProfileDef is defined using other profile definitions. Those other profile definitions are directly inserted into the underlying coordinate system.

In case of parameterized profile definitions, the Position attribute of those standard profiles is used to place the profiles relatively to each other. In case of arbitrary profile definitions, each Cartesian coordinate is given directly within the underlying coordinate system.

NOTE The black coordinate axes show the underlying coordinate system of the swept surface or swept area solid.

Twin profiles special case

If twin profiles are modeled by profile composition, the base profile should only be specified once. It is then included into the composite profile directly and additionally indirectly via IfcMirroredProfileDef. For example, a double angle made of two L100x10 with 10mm air gap between them, i.e. a _||_ shape, can be modeled as

single_L : IfcLShapeProfileDef := IfcLShapeProfileDef(AREA, ‘L100X100X10’, IfcAxis2Placement2D(IfcCartesianPoint(((.100+.010)/2., .0)), ?), .100, .100, .010, .012, ?, 0., ?, ?); double_L : IfcCompositeProfileDef := IfcCompositeProfileDef(AREA, ‘double angle’, (single_L, IfcMirroredProfileDef(AREA, ?, single_L, ?)), ‘twin profile’);

class IfcCompoundPlaneAngleMeasure : public IfcUtil::IfcBaseType

IfcCompoundPlaneAngleMeasure is a compound measure of plane angle in degrees, minutes, seconds, and optionally millionth-seconds of arc.

NOTE: IfcCompoundPlaneAngleMeasure is used where angles need to be described to an accuracy as fine as one millionth of a degree and expressed as parts of an arc. It may be used for angular measurement by surveyors or for other angular measurements where precision is required. Another usage is exact or approximate global positioning against a geographic coordinate systems using longitude and latitude.

NOTE: While the unit of measurement of the type IfcPlaneAngleMeasure depends on unit assignment (radian or degree or other derived units; globally at the IfcPoject or locally at an IfcMeasureWithUnit), the units of IfcCompoundPlaneAngleMeasure are always degrees, minutes, seconds, and millionth-seconds irrespective of unit assignments.

HISTORY New type in IFC Release 1.5.1.

Type: LIST [3:4] OF INTEGER

Value restrictions

The first integer measure is the number of degrees and is generally not range-restricted. However, when IfcCompoundPlaneAngleMeasure is used to express geographic coordinates, only latitudes of [-90, 90] and longitudes of [-180, 180] are used in practice. The second integer measure is the number of minutes and shall be in the range (-60, 60). The third integer measure is the number of seconds and shall be in the range (-60, 60). The optional fourth integer measure is the number of millionth-seconds and shall be in the range (-1 000 000, 1 000 000).

Signedness

All measure components have the same sign (positive or negative). It is therefore trivial to convert between floating point representation (decimal degrees) and compound representation regardless whether the angle is greater or smaller than zero. Example:

LOCAL a : IfcPlaneAngleMeasure := -50.975864; (* decimal degrees, -50° 58’ 33” 110400 *) b : IfcPlaneAngleMeasure; c : IfcCompoundPlaneAngleMeasure; s : IfcText; END_LOCAL;

(* convert from float to compound *) c[1] := a; -50 c[2] := (a - c[1]) * 60; -58 c[3] := ((a - c[1]) * 60 - c[2]) * 60; -33 c[4] := (((a - c[1]) * 60 - c[2]) * 60 - c[3]) * 1.e6; -110400

(* convert from compound to float *) b := c[1] + c[2]/60. + c[3]/3600. + c[4]/3600.e6; -50.975864

Use in string representations

When a compound plane angle measure is formatted for display or printout, the signs of the fractional components will usually be discarded because, to a human reader, the sign of the first component alone already indicates the sense of the angle:

(* convert from compound to human-readable string *) s := FORMAT(c[1], ‘+##’) + “000000B0” + FORMAT(ABS(c[2]), ‘##’) + ‘’’’ + FORMAT(ABS(c[3]), ‘##’) + ‘”’ + FORMAT(ABS(c[4]), ‘##’); – -50° 58’ 33” 110400

Another often encountered display format of latitudes and longitudes is to omit the signs and print N, S, E, W indicators instead, for example, 50°58’33”S. When stored as IfcCompoundPlaneAngleMeasure however, a compound plane angle measure is always signed, with same sign of all components.

IfcConnectionPointEccentricity is used to describe the geometric constraints that facilitate the physical connection of two objects at a point or vertex point with associated point coordinates. There is a physical distance, or eccentricity, etween the connection points of both object. The eccentricity can be either given by:

providing the PointOnRelatingElement and the PointOnRelatedElement, where bothpoint coordinates are not identical within a common parent coordinate system (latestly within the world coordinate system), providing the PointOnRelatingElement and the three distance measures, EccentricityInX, EccentricityInY, and EccentricityInZ (or only EccentricityInX, and EccentricityInY if the underlying coordinate system is two-dimensional), or providing both.

NOTE If both, PointOnRelatedElement, and EccentricityInX, EccentricityInY, (EccentricityInZ) are provided, the values should be consistent. In case of any non-consistency, the calculated distance between PointOnRelatingElement and PointOnRelatedElement takes precedence.

The explicit values for EccentricityInX, EccentricityInY, and EccentricityInZ are always measured in the following direction and coordinate system (defining when the value is positive or negative):

from the PointOnRelatedElement to PointOnRelatingElement within the coordinate system of the RelatingElement. in addition: when used to specify connections in structural analysis models, the IfcStructuralMember is to be used as the RelatingElement of the relationship object utilizing IfcConnectionPointEccentricity, and the IfcStructuralConnection is the RelatedElement.

IfcConnectionSurfaceGeometry is used to describe the geometric constraints that facilitate the physical connection of two objects at a surface or at a face with surface geometry associated. It is envisioned as a control that applies to the element connection relationships.

HISTORY New entity in IFC Release 2x.

IFC2x Edition 3 CHANGE The provision of topology with associated geometry, IfcFaceSurface, is enabled by using the IfcSurfaceOrFaceSurface.

Geometry use definitions The IfcSurface (or the IfcFaceSurface with an associated IfcSurface) at the SurfaceOnRelatingElement attribute defines the surface where the basic geometry items of the connected elements connects. The surface geometry and coordinates are provided within the local coordinate system of the RelatingElement, as specified at the IfcRelConnectsSubtype that utilizes the IfcConnectionSurfaceGeometry.

class IfcConstraint : public IfcUtil::IfcBaseEntity

An IfcConstraint is used to define a constraint or limiting value or boundary condition that may be applied to an object or to the value of a property.

HISTORY: New Entity in IFC Release 2.0

Use Definition IfcConstraint may be associated with any subtype of IfcRoot (unless restricted in specific subtypes) through the IfcRelAssociatesConstraint relationship in the IfcControlExtension schema, or may be associated with IfcProperty by IfcPropertyConstraintRelationship.

A constraint may aggregate other constraints through the IfcConstraintAggregationRelationship through which a logical association between constraints may be applied, or constraints may have other defined relationship to other constraints via IfcConstraintRelationship.

A constraint must have a name applied through the IfcConstraint.Name attribute and optionally, a description through IfcConstraint.Description. The grade of the constraint (hard, soft, advisory) must be specified through IfcConstraint.ConstraintGrade or IfcConstraint.UserDefinedGrade whilst the source, creating actor and time at which the constraint is created may be optionally asserted through IfcConstraint.ConstraintSource, IfcConstraint.CreatingActor and IfcConstraint.CreationTime.

A constraint may also have additional external information (such as classification or document information) associated to it by IfcExternalReferenceRelationship, accessible through inverse attribute IfcConstraint.HasExternalReferences

An IfcConstraintAggregationRelationship is an objectified relationship that enables instances of IfcConstraint subtypes to be aggregated together logically.

HISTORY New Entity in IFC Release 2.0. Modified in IFC2x2.

IFC2x4 CHANGE Subtyped from IfcConstraintRelationship

Use definition IfcConstraintAggregationRelationship allows the aggregation link between subtypes of constraint to be logically defined (AND, OR, XOR, NOTAND, NOTOR). In this way, whereby an object or property can have multiple constraints assigned, and the logical linkage between them can be specified. Thus linked constraints might show as for example (> X AND < Y) which is useful for an allowed range, or bounded value, for example, (A OR B OR C) which is valuable for an enumerated property where a selection is constrained to be (at least) one of A, B or C.

class IfcConstructionEquipmentResource : public Ifc2x3::IfcConstructionResource

IfcConstructionEquipmentResource is usage of construction equipment to assist in the performance of construction. Construction Equipment resources are wholly or partially consumed or occupied in the performance of construction.

HISTORY: New Entity in IFC Release 2.0. Base type and documentation extended in IFC2x4.

Occurrences of IfcConstructionEquipmentResource are products that are used as resources to assist the process of construction. More specifically, they are products that are standalone items brought to a project to fulfil a particular purpose. Examples might be a tower crane or other mobile crane, a screwing machine, a lifting hoist etc. They are explicitly instances of IfcProduct and may be drawn from various of the subtype, for instance IfcTransportElement, IfcDiscreteAccessory, IfcProxy (for particular cases where more precise usage details are not available).

A product that is used as an IfcConstructionEquipmentResource is referenced using the IfcRelAssignsToResource.RelatedObjects relationship.

Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.

Type use definition IfcConstructionEquipmentResource defines the occurrence of any construction equipment resource; common information about construction equipment resource types is handled by IfcConstructionEquipmentResourceType. The IfcConstructionEquipmentResourceType (if present) may establish the common type name, common properties, and common productivities for various task types using IfcRelAssignsToProcess. The IfcConstructionEquipmentResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.

Quantity use definition The quantities relating to the IfcConstructionEquipmentResource are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement.

Qto_ConstructionEquipmentResourceBaseQuantities: base quantities for all construction equipment resources.

Assignment use definition In addition to assignments specified at the base class IfcConstructionResource, a construction equipment resource may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionEquipmentResource and RelatedObjects contains one or more IfcProduct subtypes as shown in Figure 183. Such relationship indicates the equipment used as input for the resource. Such products are not contained within a building structure but are referenced within a construction spatial zone, specifically IfcSpatialZone with PredefinedType=CONSTRUCTION, which is aggregated within the IfcProject. There may be multiple chains of production such that the assigned equipment may have their own task and resource assignments for assembling such equipment.

IFC2x4 NOTE: The attribute Suppliers has been deleted; use IfcRelAssignsToResource to assign an IfcActor to fulfill the role as a supplier. The attribute UsageRatio has been deleted; use BaseQuantityConsumed and BaseQuantityProduced to indicate material usage.

Occurrences of IfcConstructionMaterialResource are consumed (wholly or partially), or occupied during a construction work task (IfcTask).

Similar to IfcConstructionProductResource, sometimes things such as 5000kg of gravel are already instantiated as an IfcProduct because it is a result of a work task (for example, &#145;transporting gravel&#146;). In this case, the instance of IfcConstructionMaterialResource can be associated with the product instance &#145;5000kg of gravel&#146; to provide more information for resource uses. Nevertheless, IfcConstructionMaterialResource should only be used to represent resource usage (for example &#145;gravel&#146;), but not product substances (for example, &#145;5000kg of gravel&#146;). Note: This class is not the same as IfcMaterial; the former can typically represent the type of bulk materials such as sand, gravels, nails and so on (note these can be instantiated from IfcProduct as well depending their uses in the system) used in a construction process. The latter is about physical materials used in a physical building element typically with detailed positioning (e.g. offset) and layering information. Quantities for an IfcConstructionMaterialResource are defined through IfcRelDefinesByProperty and use IfcElementQuantity.

Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.

Type use definition IfcConstructionMaterialResource defines the occurrence of any material resource; common information about material resource types is handled by IfcConstructionMaterialResourceType.

Such relationship indicates the physical material used as input for the resource. Such products are not contained within a building structure but are referenced within a construction spatial zone, specifically IfcSpatialZone with PredefinedType=CONSTRUCTION, which is aggregated within the IfcProject. The IfcGeographicElement object is used to represent the physical material occurrence, which may optionally have placement and representation indicating intended storage on the construction site. There may be multiple chains of production such that the assigned product material(s) may have their own task and resource assignments for transporting or extracting such material.

For instance, formworks can be instantiated as products resulting from the process &#145;constructing formwork&#146;. However, they are used as resources in the process &#145;pouring concrete&#146; in a later stage of the project.

class IfcConstructionResource : public Ifc2x3::IfcResource

IfcConstructionResource is an abstract generalization of the different resources used in construction projects, mainly labor, material, equipment and product resources, plus subcontracted resources and aggregations such as a crew resource.

A resource represents “use of something” and does not necessarily correspond to a single item such as a person or vehicle, but represents a pool of items having limited availability such as general labor or an equipment fleet. A resource can represent either a generic resource pool (not having any task assignment) or a task-specific resource allocation (having an IfcTask assignment).

HISTORY New entity in IFC2x2.

IFC2x4 CHANGE Modified in to promote ResourceIdentifer and ResourceGroup (renamed to LongDescription) to supertype IfcResource and add attributes as described.

Type use definition IfcConstructionResource defines the occurrence of any construction resource; common information about construction resource types is handled by IfcConstructionResourceType. The IfcConstructionResourceType (if present) may establish the common type name, common properties, common cost rates, and common productivities applied to specific task types. The IfcConstructionResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute as shown in Figure 186. The resource type may provide shared productivity and cost information, allowing tasks and resources to be selected according to lowest cost and/or shortest duration. Given an IfcProduct of a particular IfcTypeProduct type, an IfcTypeProcess may be selected from those assigned to the product type using IfcRelAssignsToProduct, and an IfcTypeResource may be selected from those assigned to the process type using IfcRelAssignsToProcess. Then IfcTask and IfcConstructionResource occurrences may be instantiated from the type definitions, applying productivitity and rate information to assigned quantities to calculate ResourceTime.ScheduleWork. Task durations can then be calculated by dividing ResourceTime.ScheduleWork by ResourceTime.ScheduleUsage.

Figure 186 — Construction resource type use

Composition use definition Resources may be decomposed into allocation pools using the IfcRelNests relationship as shown in Figure 187. For example, an IfcLaborResource for “Electrician” may be decomposed into three task-specific IfcLaborResource objects: “Electrical Rough-in”, “First Floor Circuits”, and “Second Floor Circuits”. Both relating and related sides may represent the same ResourceTime.ScheduleUsage quantity (for example, 6 workers time-shared), or the related side may break out ResourceTime.ScheduleUsage quantities for reserved use (for example, 4 workers and 2 workers). A common scenario is two nesting levels where the first-level resources have no task assignments; while second-level resources have specific task assignments indicating that the resource is subdivided into allocations for specific tasks. While the model allows unlimited nesting of resources, implementer agreements may restrict to two nesting levels with task assignments specifically at the second level.

Figure 187 — Construction resource composition use

Declaration use definition A root-level resource (specifically IfcCrewResource or IfcSubContractResource) is declared within the project by IfcRelDeclares where RelatingContext refers to the single IfcProject and RelatedObjects refers to one or more IfcConstructionResource, and other root-level objects within the project.

Assignment use definition A resource may be assigned to an actor by IfcRelAssignsToActor where RelatingActor refers to an IfcActor and RelatedObjects refers to one or more IfcConstructionResource or other objects. Such relationship indicates the actor responsible for allocating the resource such as partitioning into task-specific allocations, delegating to other actors, and/or scheduling over time. Note that this assignment does not indicate the person or organization performing the work; that is indicated by IfcRelAssignsToResource. The actor responsible for the resource may or may not be the same as any actor(s) performing work. A resource may be assigned to a control by IfcRelAssignsToControl where RelatingProduct refers to an IfcControl and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcWorkCalendar is assigned indicating availability of the resource, where such calendar is nested within a base calendar or an IfcWorkPlan which in turn is assigned to the IfcProject. A resource may be assigned to a group by IfcRelAssignsToGroup where RelatingGroup refers to an IfcGroup and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcAsset is assigned indicating the asset to be tracked, where such asset is nested within an IfcInventory which in turn is assigned to the IfcProject. A resource may be assigned to a product by IfcRelAssignsToProduct where RelatingProduct refers to an IfcProduct and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcElement subtype is assigned indicating the product to be constructed, where such product is connected to a spatial structure which in turn is aggregated within the IfcProject. A resource may be assigned to a process by IfcRelAssignsToProcess where RelatingProcess refers to an IfcProcess and RelatedObjects refers to one or more IfcConstructionResource or other objects. Most commonly an IfcTask is assigned indicating the task to be performed by the resource, where such task is nested within a summary task which in turn is assigned to the IfcProject. A resource may have assignments of other objects using IfcRelAssignsToResource where RelatingResource refers to the IfcConstructionResource and RelatedObjects refers to one or more objects such as IfcActor or IfcProduct subtypes. This relationship indicates specific objects assigned to fulfill resource usage. Figure 188 illustrates resource assignment.

Figure 188 — Construction resource assignment use

Constraint use definition Constraints may be applied to a resource to indicate fixed work (such as total person-hours) or fixed usage (such as simultaneous workers). The relationship IfcRelAssociatesConstraint is used where RelatingConstraint points to an IfcMetric and RelatedObjects includes the IfcConstructionResource as shown in Figure 189. IfcRelAssociatesConstraint.Name identifies the attribute to be constrained using a period (“.”) to dereference; for example, “ResourceTime.ScheduleWork” refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. The following attributes may be constrained:

‘ResourceTime.ScheduleUsage’: Indicate fixed usage (e.g. simultaneous workers) with ConstraintGrade=HARD and Benchmark=EQUALTO such that changes to ResourceTime.ScheduleWork should impact the assigned IfcTask.TaskTime.ScheduleDuration and vice-versa ‘ResourceTime.ScheduleWork’: Indicate fixed work (e.g. total person-hours) with ConstraintGrade=HARD and Benchmark=EQUALTO such that changes to ResourceTime.ScheduleUsage should impact the assigned IfcTask.TaskTime.ScheduleDuration and vice-versa.

Figure 189 — Construction resource constraint use

Time series use definition Time series may be applied to a resource to indicate the break-out of attribute values over time. The relationship IfcRelAssociatesTimeSeries is used where RelatingTimeSeries points to an IfcTimeSeries (either IfcRegularTimeSeries or IfcIrregularTimeSeries) and RelatedObjects includes the IfcConstructionResource as shown in Figure 190. IfcRelAssociatesTimeSeries.Name identifies the attribute to be constrained using a period (“.”) to dereference; for example, “ResourceTime.ScheduleWork” refers to the ScheduleWork attribute on the IfcResourceTime entity referenced on the ResourceTime attribute. Refer to attribute descriptions on IfcResourceTime for attribute-specific usage. Each IfcTimeSeriesValue indicates a LIST of values, where the sequence of the value corresponds to the IfcCostValue at IfcConstructionResource.CostRatesConsumed. For example, if CostRatesConsumed has two IfcCostValue items in the LIST, “Standard” and “Overtime”, then IfcTimeSeriesValue(IfcDuration(‘T8H0M0S’),IfcDuration(‘T2H0M0S’)) would indicate 8 hours at Standard rate and 2 hours at Overtime rate. If the list of values at IfcTimeSeriesValue.ListValues is less than the size of CostRatesConsumed, then subsequent values are considered to be zero.

Document use definition Documents may be published for work plans consisting of schedules, calendars, tasks, and resources. The relationship IfcRelAssociatesDocument may be used to preserve mappings to such document where RelatingDocument points to an IfcDocumentReference and RelatedObjects includes the IfcConstructionResource as shown in Figure 191. IfcDocumentReference.ItemReference identifies the resource within the scope of the document, such as an integer or guid. The IfcDocumentReference.ReferencedDocument corresponds to the document which is uniquely identified by IfcDocumentInformation.DocumentId and/or IfcDocumentInformation.PublicationLocation. Such document mapping allows items in the document to be updated from the building information model and vice-versa.

Figure 191 — Construction resource document use

Baseline use definition A resource may have any number of baselines defined using the relationship IfcRelDefinesByObject where RelatingObject is the “current” resource and RelatedObjects consists of multiple “baseline” resources, each representing a copy of the resource as it existed at an earlier point in time as shown in Figure 192. Each baseline IfcConstructionResource is identified by its nested IfcRelAssignsToControl relationship to an IfcWorkSchedule having PredefinedType=BASELINE, IfcWorkSchedule.CreationDate indicating the date of the baseline, and IfcWorkSchedule.Name indicating the name of the baseline.

class IfcCostItem : public Ifc2x3::IfcControl

An IfcCostItem describes a cost or financial value together with descriptive information that describes its context in a form that enables it to be used within a cost schedule. An IfcCostItem can be used to represent the cost of goods and services, the execution of works by a process, lifecycle cost and more.

Each instance of IfcCostItem may have a name and a description. Depending on the use for which the cost is intended, these values should be asserted on the basis of agreement. For instance, the Name attribute could be used to provide a common value that enables distinct instances to be brought together in a nesting arrangement (see below) while the Description attribute may be used to provide text used for item description in a costing schedule.

An IfcCostItem can link one or many IfcCostValue’s representing a unit cost, total cost, or a unit cost with one or many quantities used to generate the total cost. The quantities can be given as individual quantities, or those quantities are provided as element quantities by one or many building elements. The IfcCostValue.CostType attribute indicates the category of cost, which may be used to present the value in a particular column. For nested cost items (having IfcRelNests relationship), IfcCostValue.CostType is significant such that IfcCostValue.AppliedValue is calculated as the sum of all nested costs having the same IfcCostValue.CostType or if set to an asterisk (‘*’), then the sum of all nested costs of all cost types. An IfcCostValue may represent an original value or a value derived from formulas using IfcAppliedValueRelationship. For example, taxes may be calculated as a percentage of a subtotal.

HISTORY New Entity in IFC Release 2.0. IFC2x4 CHANGE Attribute PredefinedType, CostValues, and CostQuantities added.

Classification Use Definition

Instances of IfcCostItem are used for cost estimates, budgets, and other forms, where a variety of identification codes are used extensively to identify the meaning of the cost. Examples include project phase codes, CSI codes, takeoff sequence numbers, and cost accounts. The model allows for all classes that are ultimately subtypes of IfcObject to inherit the ability to have one or more instances of IfcClassificationReference to be assigned. Where identification codes are required, the generic IfcRelAssociatesClassification facility should be used.

Composition Use Definition

An IfcCostItem can nest other instances of IfcCostItem through its relationships to IfcRelNests. This can be used to enable the development of complex groups of costs as may be found in cost schedules through to pages, sections and complete cost schedules.

There is always a summary cost item as the root item of the tree representing the cost item nesting. Subsequent instances of IfcCostItem are assigned to the summary cost item using IfcRelNests. The summary cost item itself is assigned to IfcCostSchedule through the IfcRelAssignsToControl relationship.

Figure 157 illustrates a cost item composition used for a cost schedule. Each line item has a quantity and separate unit costs where IfcCostValue.CostType indicates the category of cost. The summary item has a hierarchy of costs calculated according to IfcAppliedValueRelationship.ArithmeticOperator, where IfcCostValue.CostType identifies the category to be totalled. The Tax component has IfcCostValue.CostType set to ‘Material’ which indicates it is the sum of all nested values of the ‘Material’ category ($3 x 3000 + $118 x 100 = $20800). The Subtotal component has IfcCostValue.CostType set to an asterisk (‘*’) which indicates it is the sum of all nested values of all categories.

Figure 157 — Cost composition

Assignment Use Definition

An IfcCostItem can be calculated based on quantities from objects through its relationship to IfcRelAssignsToControl.

For quantity-based costing, IfcElement, IfcTask, or IfcResource occurrence subtypes may be used. Multiple elements may be assigned of the same or different types, using IfcPhysicalQuantity entities defined at each object. Each IfcPhysicalQuantity type must be identical (for example, all values are IfcAreaQuantity) such that they can be added together.

For rate-based costing (specifically for IfcCostScheduleTypeEnum.SCHEDULEOFRATES), a single IfcTypeProduct, IfcTypeProcess, or IfcTypeResource subtype may be used to reflect rates for occurrences of such types. This enables the possibility to generate a quantity-based cost schedule for occurrences based on types with rate-based cost schedules.

IfcRelAssignsToControl is also used in the opposite direction to link the root IfcCostItem to an IfcCostSchedule where RelatingControl is the IfcCostSchedule.

Figure 158 illustrates cost item assignment derived from building elements. The IfcRelAssignsToControl relationship indicates building elements for which quantities are derived. Not shown, costs may also be derived from building elements by traversing assignment relationships from the assigned IfcProduct to IfcProcess to IfcResource, where all costs ultimately originate at resources. It is also possible for cost items to have assignments from processes or resources directly.

Alternatively, if the IfcCostSchedule is aggregated within another IfcControl object, then it shall not have a direct declaration relationship (whereas the containing object may have a declaration relationship).

Assignment Use Definition The IfcCostSchedule may be assigned to the following entities using relationships as indicated:

IfcActor (IfcRelAssignsToActor): Persons and organizations involved in the preparation, submittal, and as target users.

The IfcCostSchedule may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcCostSchedule and RelatedObjects contains one or more objects of the following types: IfcCostItem: Indicates costs published within this cost schedule, typically a single root cost item forming a hierarchy of nested cost items.

Classification Use Definition Classifications may be applied using IfcRelAssociatesClassification where RelatedObjects contains the IfcCostSchedule and RelatingClassification refers to an IfcClassification or IfcClassificationReference.

IfcClassification: Classifications to be used for cost items within the cost schedule.

Approval Use Definition Approvals may be associated to indicate the status of acceptance or rejection using the IfcRelAssociatesApproval relationship where RelatingApproval refers to an IfcApproval and RelatedObjects contains the IfcCostSchedule. Approvals may be split into sub-approvals using IfcApprovalRelationship to track approval status separately for each party where RelatingApproval refers to the higher-level approval and RelatedApprovals contains one or more lower-level approvals. The hierarchy of approvals implies sequencing such that a higher-level approval is not executed until all of its lower-level approvals have been accepted.

IfcCostValue is an amount of money or a value that affects an amount of money.

HISTORY: New Entity in IFC Release 1.0

Use definitions Each instance of IfcCostValue may also have a CostType. There are many possible types of cost value that may be identified. While there is a broad understanding of the meaning of names that may be assigned to different types of costs, there is no general standard for naming cost types nor are there any broadly defined classifications. To allow for any type of cost value, the IfcLabel datatype is assigned.

The following defines some cost types that might be applied:

Annual rate of return Bonus Bulk purchase rebate Contract Consultancy Delivery Estimated cost Hire Installation Interest rate Labor Lease List price Maintenance Material Overhead Postage and packing Profit Purchase Rental Repair Replacement Sale Small quantity surcharge Spares Storage Sub-Contract Trade discount Transportation Waste allowance Whole life

In the absence of any well-defined standard, it is recommended that local agreements should be made to define allowable and understandable cost value types within a project or region.

class IfcCovering : public Ifc2x3::IfcBuildingElement

Definition from ISO 6707-1:1989: term used: Finishing - final coverings and treatments of surfaces and their intersections. A covering is an element which covers some part of another element and is fully dependent on that other element. The IfcCovering defines the occurrence of a covering type, that (if given) is expressed by the IfcCoveringType. Examples of coverings include wall claddings, floorings and suspended ceilings. Coverings are elements with relationships to the covered element and the space on the other side, they may contain openings, assigned by IfcRelVoidsElement, material information, assigned by IfcRelAssociatesMaterial, and others. NOTE A more basic information about claddings, floorings, and ceilings of a space can be attached to IfcSpace’s using the Pset_SpaceCommon properties. Then only a name can be provided and the covering quantities would be interpreted from the space quantities. Coverings can be assigned to

a space represented by IfcSpace

using the inverse relationship CoversSpaces pointing to IfcRelCoversSpaces. The space is then accessible via IfcRelCoversSpaces.RelatedSpace. It defines to which space a covering is facing towards.

NOTE The mere containment relationship between an IfcCovering and an IfcSpace is created by using IfcRelContainedInSpatialStructure

a space boundary represented by IfcRelSpaceBoundary

using the inverse relationship ProvidesBoundaries pointing to IfcRelSpaceBoundary. The space is then accessible via IfcRelSpaceBoundary.RelatingSpace.

a building element represented by IfcBuildingElement

using the inverse relationship Covers pointing to IfcRelCoversBldgElements. The building element is then accessible via IfcRelCoversBldgElements.RelatingBuildingElement.

The following guideline shall apply:

(default) if the space has coverings that may not have an own shape representation and no defined relationships to the building elements they cover, then the IfcCovering shall be assigned to IfcSpace using the IfcRelCoversSpaces relationship, if the space has coverings that have an own shape representation and the space has defined space boundaries, then the covering, which relates to that space, may be assigned to the space boundaries using the link toIfcRelSpaceBoundary, if the covering does not relate to a space, then the covering should be assigned to the building element or a distribution element using the IfcRelCoversBldgElements relationship.

HISTORY New entity in IFC Release 1.0. IFC2x CHANGE The attribute PredefinedType is now optional and should only be inserted when no type information, given by IfcCoveringType, is assigned to the IfcCovering occurrence by IfcRelDefinesByType. IFC2x4 CHANGE The IfcCovering is restricted to coverings of building elements by having RelatingBuildingElement pointing to IfcBuildingElement.

Type Use Definition The IfcCovering defines the occuurence of any covering, common information about covering types (or styles) is handled by IfcCoveringType. The IfcCoveringType (if present) may establish the commontype name, usage (or predefined) type, common set of properties, common material layer set, and common shape representations (using IfcRepresentationMap). The IfcCoveringType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsDefinedBy attribute. As an additional use agreement for standard coverings (i.e. slabs with constant thickness along the extrusion direction), the IfcCoveringType should have a unique IfcMaterialLayerSet, that is referenced by theIfcMaterialLayerSetUsage assigned to all occurrences of this covering type.

Figure 91 illustrates assignment of IfcMaterialLayerSetUsage and IfcMaterialLayerSet to the covering type and the covering occurrence.

Figure 91 — Covering material usage

If an IfcCoveringType is assigned to the IfcCovering, the attribute PredefinedType shall not be assigned, or shall be identical to IfcCoveringType.PredefinedType. Property Set Use Definition: The property sets relating to the IfcCovering are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcCovering are part of this IFC release:

Pset_CoveringCommon: common property set for all covering occurrences

Pset_CoveringCeiling: specific property set for all occurrences of coverings with the PredefinedType: CEILING Pset_CoveringFlooring: specific property set for all occurrences of coverings with the PredefinedType: FLOORING

Quantity Use Definition: The quantities relating to the IfcCovering are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement. Quantities shall never be assigned to the IfcCoveringType.

Qto_CoveringBaseQuantities: base quantities for all covering occurrences.

Containment Use Definition The IfcCovering has a containment relationship within the hierarchical spatial structure.

The IfcCovering is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, referring to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes of IfcSpatialStructureElement are valid spatial containers, with IfcSpace being the default container.

Geometry Use Definitions The geometric representation of IfcCovering is given by the IfcProductDefinitionShape, allowing multiple geometric representation. Included are: Local Placement The local placement for IfcCovering is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the same IfcSpatialStructureElement , which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the IfcCovering, however, is assigned to an IfcBuildingElement, and this element defines its own local placement, than the PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the IfcBuildingElement. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations The geometric representation of the IfcCovering depends on two criteria:

Does it define an area or a volume? Is the base surface (either the IfcRelSpaceBoundary or the surface of the IfcBuildingElement it relates to) a planar surface or a cylindrical surface?

GeometricSet Representation The ‘GeometricSet’ geometric representation of IfcCovering supports area definitions as 3D surfaces.

RepresentationIdentifier : ‘Surface’ RepresentationType : ‘GeometricSet’

The following additional constraints apply to the ‘GeometricSet’ representation of IfcCovering:

for planar base surfaces - bounded surface representation for cylindrical base surfaces - swept surface representation

Figure 92 illustrates a planar surface representation where the area of IfcCovering is given by an IfcPolyLoop for planar base surfaces (here given by the IfcRelSpaceBoundary).

The implicit planar surface of the IfcPolyLoop shall be identical with the planar surface defined by the IfcRelSpaceBoundary.

Figure 92 — Covering surface planar

Figure 93 illustrates a cylindrical surface representation where the area of the IfcCovering is given by an IfcSurfaceOfLinearExtrusion for cylindrical base surfaces (here given by the IfcRelSpaceBoundary - such as caused by a round wall).

The geometry representation of the IfcCovering is given by the IfcTrimmedCurved (the Curve parameter of the IfcArbitraryOpenProfileDef - in cases of faceted representation also an IfcPolyline). It is extruded within the plane of the base surface using the Depth parameter of the IfcSurfaceOfLinearExtrusion.

Figure 93 — Covering surface cylindrical

SweptSolid Representation The ‘SweptSolid’ geometric representation of IfcCovering supports volume definitions as 3D solids.

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SweptSolid’

The following additional constraints apply to the ‘SweptSolid’ representation of IfcCovering:

for planar base surfaces - swept area representation for cylindrical base surfaces - swept area representation

Figure 94 illustrates a body representation where the volume of IfcCovering is given by an IfcExtrudedAreaSolid for planar base surfaces (here given by the IfcRelSpaceBoundary).

The extruded area (IfcArbitraryClosedProfileDef) shall be coplanar to the surface defined by the IfcRelSpaceBoundary.

Figure 94 — Covering body planar

Figure 95 illustrates a body representation where the volume of the IfcCovering is given by an IfcExtrudedAreaSolid for cylindrical base surfaces (here given by the IfcRelSpaceBoundary - such as caused by a round wall).

The geometry representation of the IfcCovering is given by the IfcCompositeCurve (the OuterCurve parameter of the IfcArbitraryClosedProfileDef - in cases of faceted representation also a closed IfcPolyline). It is extruded along the plane of the base surface using the Depth parameter of the IfcSurfaceOfLinearExtrusion.

common properties within shared property sets common material (layer set) information common shape representations

It is used to define an covering specification or covering style (i.e. the specific product information, that is common to all occurrences of that product type). Covering types may be exchanged without being already assigned to occurrences. The occurrences of the IfcCoveringType are represented by instances of IfcCovering

HISTORY New entity in Release IFC2x Edition 2.

Informal proposition

The material assignment, if provided using the IfcRelAssociatesMaterial relationship, shall not reference the IfcMaterialLayerSetUsage.

Material Use Definition The material of the IfcCoveringType is defined by the IfcMaterialLayerSet or as fall back by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. Property Set Use Definition: The shared property sets relating to the IfcCoveringType are defined by the IfcPropertySet and are attached by the HasPropertySets attribute. The following property set definitions specific to the IfcCoveringType are part of this IFC release: NOTE There is no differentiation between properties within the property set that are only assignable to IfcCoveringType and those that are only assignable to IfcCovering. If the same property is assigned to the IfcCoveringType and the IfcCovering being an occurrence of the IfcCoveringType, then the occurrence property overrides the type property.

Pset_CoveringCommon: common property set for all covering types

Pset_CoveringCeiling: specific property set for all occurrences of covering types with the PredefinedType: CEILING Pset_CoveringFlooring: specific property set for all occurrences of coverings with the PredefinedType: FLOORING

Geometry Use Definition: The IfcCoveringType may define the shared geometric representation for all covering occurrences. The RepresentationMaps attribute refers to a list of IfcRepresentationMap’s, that allow for multiple geometric representations (e.g. with IfcShaperepresentation’s having an RepresentationIdentifier ‘Box’, ‘Surface’, or ‘Body’). (See geometric use definition of IfcCovering for further information). NOTE If the IfcCoveringType has an associated IfcMaterialLayerSet, then no shared geometric representation shall be provided. NOTE The product shape representations are defined as RepresentationMaps (attribute of the supertype IfcTypeProduct), which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[n] being an IfcMappedItem. See IfcTypeProduct for further information. NOTE The values of attributes RepresentationIdentifier and RepresentationType of IfcShapeRepresentation are restricted in the same way as those for IfcCoveringType.

IfcCrewResource represents a collection of internal resources used in construction processes.

HISTORY: New Entity in IFC Release 2.0. Base type and documentation extended in IFC2x4

Identification of people and equipment of a crew is achieved through their specification at the level of the component. Therefore, knowing which persons are within a crew is achieved through identifying the persons assigned to each IfcLaborResource within the IfcCrewResource. Similarly, identifying that a screwing machine for pipe fitting forms part of the crew is achieved by relating an appropriate instance of IfcElementComponent to the IfcConstructionEquipmentResource forming an element of the IfcCrewResource.

Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.

Type use definition IfcCrewResource defines the occurrence of any crew resource; common information about crew resource types is handled by IfcCrewResourceType. The IfcCrewResourceType (if present) may establish the common type name, common properties, and common productivities for various task types using IfcRelAssignsToProcess. The IfcCrewResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.

class IfcCsgSolid : public Ifc2x3::IfcSolidModel

Definition from ISO/CD 10303-42:1992: A solid represented as a CSG model is defined by a collection of so-called primitive solids, combined using regularized Boolean operations. The allowed operations are intersection, union, and difference. As a special case a CSG solid can also consists of a single CSG primitive.

A CSG solid requires two kinds of information for its complete definition: geometric and structural.

The geometric information is conveyed by solid models. These typically primitive volumes such as cylinders, wedges and extrusions, but can include general B-Rep models. Solid models can also be half space solids.

The structural information is in a tree (strictly an acyclic directed graph) of Boolean result and CSG solids, which represent a &#8216;recipe&#8217; for building the solid. The terminal nodes are the geometric primitives and other solids. Every CSG solid has precisely one Boolean result associated with it which is the root of the tree that defines the solid. (There may be further Boolean results within the tree as operands). The significance of a CSG solid entity is that the solid defined by the associated tree is thus identified as a significant object itself, and in this way it is distinguished from other Boolean result entities representing intermediate results during the construction process.

Definition from IAI: The following primitive volumes can be parts of the CSG tree: solid models, i.e. faceted B-Rep (IfcFacetedBrep, IfcFacetedBrepWithVoids), swept area solid (IfcExtrudedAreaSolid, IfcRevolvedAreaSolid, IfcSurfaceCurveSweptAreaSolid), swept disk solids (IfcSweptDiskSolid), half space solids (IfcHalfSpaceSolid and subtypes), and CSG primitives (subtypes of IfcCsgPrimitive3D).

NOTE Corresponding ISO 10303-42 entity: csg_solid, please refer to ISO/IS 10303-42:1994, p.174 for the final definition of the formal standard.

class IfcCShapeProfileDef : public Ifc2x3::IfcParameterizedProfileDef

IfcCShapeProfileDef defines a section profile that provides the defining parameters of a C-shaped section to be used by the swept area solid. This section is typically produced by cold forming steel. Its parameters and orientation relative to the position coordinate system are according to the following illustration. The centre of the position coordinate system is in the profile’s centre of the bounding box.

HISTORY New entity in IFC2x2.

IFC2x3 CHANGE All profile origins are now in the center of the bounding box.

IFC2x4 CHANGE Type of InternalFilletRadius relaxed to allow for zero radius. Trailing attribute CentreOfGravityInX deleted, use respective property in IfcExtendedProfileProperties instead.

Figure 315 illustrates parameters of the C-shape profile definition. The parameterized profile defines its own position coordinate system. The underlying coordinate system is defined by the swept area solid that uses the profile definition. It is the xy plane of:

IfcSweptAreaSolid.Position

By using offsets of the position location, the parameterized profile can be positioned centric (using x,y offsets = 0.), or at any position relative to the profile. The parameterized profile is defined by a set of parameter attributes. In the illustrated example, the ‘CentreOfGravityInX’ property in IfcExtendedProfileProperties, if provided, is negative.

IFC2x4 CHANGE Subtyped from IfcResourceLevelRelationship, attribute order changed.

Use definitions An IfcCurrencyRelationship is used where there may be a need to reference an IfcCostValue in one currency to an IfcCostValue in another currency. It takes account of fact that currency exchange rates may vary by requiring the recording the date and time of the currency exchange rate used and the source that publishes the rate. There may be many sources and there are different strategies for currency conversion (spot rate, forward buying of currency at a fixed rate).

class IfcCurtainWall : public Ifc2x3::IfcBuildingElement

Definition from ISO 6707-1:1989: Non load bearing wall positioned on the outside of a building and enclosing it. A curtain wall is an exterior wall of a building which is an assembly of components, hung from the edge of the floor/roof structure rather than bearing on a floor. Curtain wall is represented as a building element assembly and implemented as a subtype of IfcBuildingElement that uses an IfcRelAggregates relationship. HISTORY New Entity in IFC Release 2.0

Type Use Definition IfcCurtainWall defines the occuurence of any curtain wall, common information about curtain wall types (or styles) is handled by IfcCurtainWallType. The IfcCurtainWallType (if present) may establish the commontype name, usage (or predefined) type, common material information, common set of properties and common shape representations (using IfcRepresentationMap). The IfcCurtainWallType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsDefinedBy attribute. If no IfcCurtainWallType is attached(i.e. if only occurrence information is given) the predefined type may be given by using the ObjectType attribute. NOTE Since the IfcCurtainWall might be represented as an aggregate of parts, e.g. represented by IfcMember, or IfcPlate, these individual parts may have type information attached (represented e.g. by IfcMemberType, or IfcPlateType). Property Set Use Definition: The property sets relating to the IfcCurtainWall are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcCurtainWall are part of this IFC release:

Pset_CurtainWallCommon: common property set for all curtain wall occurrences

Quantity Use Definition The quantities relating to the IfcCurtainWall are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement. Quantities shall never be assigned to the IfcCurtainWallType.

Qto_CurtainWallBaseQuantities: base quantities for all curtain wall occurrences.

Geometry Use Definitions: The geometric representation of IfcCurtainWall is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Independent geometric representations, as described below, should only be used when the IfcCurtainWall is not defined as an aggregate. If defined as an aggregate, the geometric representation is the sum of the representations of the components within the aggregate. Local placement The local placement for IfcCurtainWall is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the same IfcSpatialStructureElement that is used in the ContainedInStructure inverse attribute or to a referenced spatial structure element at a higher level. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

If the IfcCurtainWall establishes an aggregate, then all contained elements (defined by the IsDecomposedBy inverse attribute) shall be placed relative to the IfcCurtainWall.ObjectPlacement. Geometric Representation The geometric representation of IfcCurtainWall is defined using the following multiple shape representations for its definition:

Axis: A two-dimensional open curve (for restrictions see below) defining the axis for the curtain wall.

This is an optional representation for curtain walls.

Body: A surface model or boundary representation model representation defining the 3D shape of the curtain wall.

If the IfcCurtainWall has components (referenced by SELF\IfcObject.IsDecomposedBy) then no independent shape representation with RepresentationType = ‘Body’ shall be defined. The body of IfcCurtainWall is then geometrically represented by the shape representation of its components. The components are accessed via SELF\IfcObject.IsDecomposedBy[1].RelatedObjects.

If the IfcCurtainWall has no components defined (empty set of SELF\IfcObject.IsDecomposedBy) then the IfcCurtainWall may be represented by an shape representation with the RepresentationIdentifier = ‘Body’.

Axis Representation The axis geometric representation of IfcCurtainWall is defined using the ‘Axis’ representation. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Axis’ RepresentationType : ‘Curve2D’

The following additional constraints apply to the ‘Axis’ representation:

Axis : IfcPolyline having two Points, or IfcTrimmedCurve with BasisCurve of Type IfcLine or IfcCircle.

Body Representation The body shape representation of IfcCurtainWall is defined using the ‘Body’ representation. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SurfaceModel’, ‘Brep’ and ‘MappedRepresentation’

An own ‘Body’ representation shall only be included if no components of the curtain wall are defined.

NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

A curtain wall type is used to define the common properties of a certain type of curtain wall that may be applied to many instances of that type to assign a specific style.

Definition from ISO/CD 10303-42:1992: The curve bounded surface is a parametric surface with curved boundaries defined by one or more boundary curves. The bounded surface is defined to be the portion of the basis surface in the direction of N x T from any point on the boundary, where N is the surface normal and T the boundary curve tangent vector at this point. The region so defined shall be arcwise connected.

The IfcCurveBoundedPlane is a specialized bounded surface class that deals only with bounding basis plane surfaces. The definition varies from STEP as outer and inner boundaries are separated attributes and refer to IfcCurve. The only basis surface that is allowed is of type IfcPlane, and the implicit_outer attribute has not been incorporated, since only unbounded surfaces are used as basis surface.

The BasisSurface is an IfcPlane that establishes the position coordinate system by SELF\IfcElementarySurface.Position. The OuterBoundary and the InnerBoundaries (if provided) shall lie on the surface of IfcPlane. Therefore the IfcCurve’s establishing the outer and inner boundaries shall be:

either a 2D curve within the XY plane of the position coordinate sytem of IfcPlane or a 3D curve with all coordinates having a z value = 0.

class IfcCurveStyle : public Ifc2x3::IfcPresentationStyle

Definition from ISO/CD 10303-46:1992: A curve style specifies the visual appearance of curves.

An IfcCurveStyle provides the style table for presentation information assigned to geometric curves. The style is defined by a color, a font and a width. The IfcCurveStyle defines curve patterns as model patterns, that is, the distance between visible and invisible segments of curve patterns are given in model space dimensions (that have to be scaled using the target plot scale).

Styles are intended to be shared by multiple IfcStyledItem’s, assigning the style to occurrences of (subtypes of) IfcGeometricRepresentationItem’s. Measures given to a font pattern or a curve width are given in global drawing length units.

NOTE global units are defined at the single IfcProject instance, given by UnitsInContext:IfcUnitAssignment, the same units are used for the geometric representation items and for the style definitions.

The measure values for font pattern and curve width apply to the model space with a target plot scale provided for the correct appearance in the default plot scale.. For different scale and projection dependent curve styles a different instance of IfcCurveStyle needs to be used by IfcPresentationStyleAssignment for different IfcGeometricRepresentationSubContext dependent representations.

NOTE the target plot scale is given by IfcGeometricRepresentationSubContext.TargetScale.

An IfcCurveStyle can be assigned to IfcGeometricRepresentationItem’s via the IfcPresentationStyleAssignment through an intermediate IfcStyledItem or IfcAnnotationCurveOccurrence.

class IfcDerivedProfileDef : public Ifc2x3::IfcProfileDef

IfcDerivedProfileDef defines the profile by transformation from the parent profile. The transformation is given by a two dimensional transformation operator. Transformation includes translation, rotation, mirror and scaling. The latter can be uniform or non uniform. The derived profiles may be used to define swept surfaces, swept area solids or sectioned spines.

The transformation effects the position, rotation, mirroring or scale of the profile at the underlying coordinate system, i.e. the coordinate system defined by the swept surface or swept area solid that uses the profile definition. It is the xy plane of either:

IfcSweptSurface.Position IfcSweptAreaSolid.Position

or in case of sectioned spines the xy plane of each list member of IfcSectionedSpine.CrossSectionPositions. The position and potential rotation of the ParentProfile within the underlying coordinate system is taken into consideration before applying the Cartesian transformation operator.

Note, if only mirroring is required, IfcMirroredProfileDef should be used instead.

HISTORY: New entity in IFC Release 2x.

Figure 316 illustrates examples of derived profiles.

Parameter The IfcDerivedProfileDef is defined using the IfcCartesianTransformationOperator2D (CTO), which is applied to the parent profile definition.

Example The example shows an uniform scaling and a transformation of an IfcRectangleProfileDef to match the lower-left cardinal point. The attributes of the CTO are:

Axis1 = NIL (defaults to 1.,0.) Axis2 = NIL (defaults to 0.,1.) LocalOrigin = IfcCartesianPoint(,) Scale = 2.

Note: The ParentProfile has a Position = IfcCartesianPoint(,) already.

Parameter The IfcDerivedProfileDef is defined using non uniform transformationsby applying the IfcCartesianTransformationOperator2DnonUniform as a subtype of the 2D CTO.

Example The example shows a non-uniform scaling and a translation of an IfcRectangleProfileDef to match the lower-left cardinal point. The attributes of the CTO are:

Axis1 = NIL (defaults to 1.,0.) Axis2 = NIL (defaults to 0.,1.) LocalOrigin = IfcCartesianPoint(0.,<1/2 YDim) Scale = 1. Scale2 = 2.

Note: The ParentProfile has a Position = IfcCartesianPoint(,) already.

Parameter The IfcDerivedProfileDef is defined using mirroring by applying the IfcCartesianTransformationOperator2D (CTO) to the parent profile.

Example The example shows a mirroring of an IfcLShapeProfileDef to match the centre cardinal point. The attributes of the CTO are:

Axis1 = (-1.,0.) Axis2 = NIL (defaults to 0.,1.) LocalOrigin = IfcCartesianPoint(0.,0.) Scale = NIL (defaults to 1.)

Note: The ParentProfile has a Position = IfcCartesianPoint(0.,0.).

This example is for illustration only. If the transformation results only in mirroring like shown in the example, then IfcMirroredProfileDef should be used instead of IfcDerivedProfileDef.

Note: The following color map applies:

black coordinate axes show the underlying coordinate system of the swept surface, swept area solid, or sectioned spine

red coordinate axes show the position coordinate system of the parent profile

brown coordinate axes show the position coordinate system of the derived profile

class IfcDistributionControlElement : public Ifc2x3::IfcDistributionElement

The distribution element IfcDistributionControlElement defines occurrence elements of a building automation control system that are used to impart control over elements of a distribution system.

This class defines elements of a building automation control system. These are typically used to control distribution system elements to maintain variables such as temperature, humidity, pressure, flow, power, or lighting levels, through the modulation, staging or sequencing of mechanical or electrical devices. The three general functional categories of control elements are as follows:

Impart control over flow control elements (IfcFlowController) in a distribution system such as dampers, valves, or relays, typically through the use of actuation (IfcActuator). Sensing elements (IfcSensor) that measure changes in the controlled variable such as temperature, humidity, pressure, or flow. Controllers (IfcController) typically classified according to the control action they seek to perform and generally responsible for making decisions about the elements under control.

Since this class and its subtypes typically relate to many different distribution flow elements (IfcDistributionFlowElement), the objectified relationship IfcRelFlowControlElements has been provided to relate control and flow elements as required.

IFC2x4 CHANGE: ControlElementId attribute deleted; replaced by classification usage. HISTORY: New entity in IFC R2.0.

Type Use Definition IfcDistributionControlElement defines the occurrence of any distribution control element; common information about distribution control element types is handled by IfcDistributionControlElementType. The IfcDistributionControlElementType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcDistributionControlElementType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcDistributionControlElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionControlElement occurrence using the IfcRelDefinesByObject relationship. Direct instantiation of IfcDistributionControlElement with IfcObject.ObjectType asserted provides the meaning of a distribution control element proxy.

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcDistributionControlElementType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcDistributionControlElementType.HasPropertySets. If both are given, then the properties directly defined at IfcDistributionControlElement override the properties defined at IfcDistributionControlElementType. Refer to the documentation at the supertype IfcDistributionElement and ancestors for inherited property set definitions.

Classification Use Definition In addition to general product and project classification (UniFormat, etc.), classifications may also be applied to indicate a device address or addressing scheme using IfcRelAssociatesClassification where RelatedObjects contains the IfcDistributionControlElement and RelatingClassification refers to an IfcClassification or IfcClassificationReference.

IfcClassification: Indicates an addressing scheme managed by the device where ReferenceTokens defines the format of the address to be specified at IfcClassificationReference.ItemReference. A classification hierarchy may optionally be provided indicating detected or provisioned device addresses. IfcClassificationReference: Indicates the address of the control element where Identification uniquely identifies the element within the control system as determined by the ClassificationSource. Several examples are illustrated:

‘BACnet’: BACnetObjectIdentifier in the decimal form ‘12.15’ (Digital Input #15) indicating type ID and instance ID. ‘IP’: IP Address in the decimal form ‘192.168.1.2’ such as for an IPv4 network. ‘OPC’: Hierarchical ItemID in the alphanumeric form ‘B204.Tank2.Temperature’ ‘X-10’: Alphabetic and numeric code in the form ‘B12’ (House B, Device 12) indicating House Code and Device Code.

Figure 147 illustrates classification usage.

Figure 147 — Distribution control classification

Composition Use Definition The IfcDistributionControlElement may be decomposed into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcDistributionControlElement and RelatedObjects contains one or more components. Likewise, a control element may be aggregated within another element. For example, a thermostat may contain temperature sensors, and a programmable logic controller may contain virtual (software-based) control elements. Standard types for composition are defined at subtypes.

Connection Use Definition The IfcDistributionControlElement may be connected to other objects as follows using the indicated relationship:

IfcSpatialStructureElement (IfcRelContainedInSpatialStructure) : Indicates the spatial location containing the element. If an element is aggregated within another element, then only the top-level element participates in this relationship. IfcElement (IfcRelConnectsElements) : Indicates physical connectivity with another element (but not embedding or flow control), such as a sensor attached to a wall. IfcRelConnectsElements.RelatingElement refers to the anchored side (for example, wall hosting sensor). IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for control signal transmission or electric power. Standard port names, types, and directions are defined at subtypes. IfcDistributionFlowElement (IfcRelFlowControlElements) : Indicates a flow element is sensed or controlled by the control element, such as a tank for a level sensor or a valve for an actuator.

Assignment Use Definition The IfcDistributionControlElement may be assigned to the following entities using relationships as indicated:

IfcDistributionSystem (IfcRelAssignsToGroup): Indicates a system containing interconnected devices, where control elements are typically part of a control system having PredefinedType=CONTROL. IfcPerformanceHistory (IfcRelAssignsToControl): Indicates realtime or historical infomation captured for the device.

The IfcDistributionControlElement may have assignments of its own using the IfcRelAssignsToProduct relationship where RelatingProduct refers to the IfcDistributionControlElement and RelatedObjects contains one or more objects of the following types:

IfcTask: Indicates tasks used to purchase, install, renovate, demolish, operate, or otherwise act upon the element. If the element has a type, available task types are assigned to the element type. IfcProcedure: Indicates procedures used to operate the element. If the element has a type, available procedure types are assigned to the element type. IfcEvent: Indicates events raised by the element, sequenced by procedures to be followed. If the element has a type, available event types are assigned to the element type.

Material Use Definition The material of the IfcDistributionControlElement is defined using one of the following entities:

IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.

IfcMaterial: For elements comprised of a single material, this indicates the material.

The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcDistributionControlElementType, defining the common attribute data for all occurrences of the same type. Standard names and material types are defined at subtypes.

Representation Use Definition The following shape representations are supported for subtypes of IfcDistributionControlElement, distinguished by IfcShapeRepresentation.RepresentationIdentifier:

‘Footprint’: Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of ‘GeometricCurveSet’ and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.

‘Body’: Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of ‘SurfaceModel’, ‘SolidModel’, or any solid model specializations including ‘Brep’, ‘AdvancedBrep’, ‘SweptSolid’, ‘AdvancedSweptSolid’, ‘CSG’, ‘Clipping’, or ‘SectionedSpine’).

‘Clearance’: Represents the 3D clearance volume of the item having RepresentationType of ‘Surface3D’. Such clearance region indicates space that should not intersect with the ‘Body’ representation of other elements, though may intersect with the ‘Clearance’ representation of other elements. The particular use of clearance space may be for safety, maintenance, or other purpose.

For all representations, if a IfcDistributionControlElement occurrence is defined by a IfcDistributionControlElementType having a representation of the same identifier, then ‘MappedRepresentation’ should be used at the occurrence unless overridden.

If materials are defined, geometry of each representation (most typically the ‘Body’ representation) may be organized into shape aspects where styles may be derived by correlating IfcShapeAspect.Name to a corresponding material (IfcMaterialConstituent.Name).

‘Body’: Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of ‘SurfaceModel’, ‘SolidModel’, or any solid model specializations including ‘Brep’, ‘AdvancedBrep’, ‘SweptSolid’, ‘AdvancedSweptSolid’, ‘CSG’, ‘Clipping’, or ‘SectionedSpine’).

‘Clearance’: Represents the 3D clearance volume of the item having RepresentationType of ‘Surface3D’. Such clearance region indicates space that should not intersect with the ‘Body’ representation between element occurrences, though may intersect with the ‘Clearance’ representation of other element occurrences. The particular use of clearance space may be for safety, maintenance, or other purpose.

NOTE: The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which get assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

class IfcDistributionElement : public Ifc2x3::IfcElement

Definition from IAI: Generalization of all elements that participate in a distribution system. Typical examples of IfcDistributionElement are (among others):

building service elements within a heating systems building service elements within a cooling system building service elements within a ventilation system building service elements within a plumbing system

e.g. sanitary elements, fire suppression elements

electrical elements elements within a communication network

The IfcDistributionElement is further specialized in the IFC model. Direct instantiation of IfcDistributionElement without an assigned subtype of IfcDistributionElementType provides the meaning of an distribution element proxy. HISTORY New entity in IFC Release 1.5. IFC2x4 CHANGE The entity is marked as deprecated for instantiation - will be made ABSTRACT after IFC2x4. Relationship Use Definition

Ports - information, whether the distribution element has ports for system connections

objectified relationship: IfcRelConnectsPortToElement object referenced by relationship: IfcPort inverse attribute: HasPorts

Type Use Definition The IfcDistributionElement defines the occurrence of any HVAC, electrical, sanitary or other element within a distribution system. Common information about distribution element types (or styles) is handled by subtypes of IfcDistributionElementType. The IfcDistributionElementType (if present) may establish the common type name, usage (or predefined) type, common material, common set of properties and common shape representations (using IfcRepresentationMap). The IfcDistributionElementType is attached using the IfcRelDefinedByType.RelatingType objectified relationship and is accessible by the inverse IsDefinedBy attribute. The assignment of types to distribution element occurrences is vital for providing the additional meaning, or ontology, of the distribution element. Many specialized type are defined in other schemas of the IFC specification. Quantity Use Definition The quantities relating to the IfcDistributionElement are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties. A detailed specification for individual quantities is introduced at the level of subtypes of IfcDistributionElement. Containment Use Definition The IfcDistributionElement may participate in two different containment relationships. The first (and in most implementation scenarios mandatory) relationship is the hierachical spatial containment, the second (optional) relationship is the aggregation within anelement assembly.

The IfcDistributionElement is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, referring to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes ofIfcSpatialStructureElement are valid spatial containers, with IfcSpace being the default container. The IfcDistributionElement may be aggregated into an element assembly using the objectified relationship IfcRelAggregates, referring to it by its inverse attribute SELF\IfcObjectDefinition.Decomposes. Any subtype of IfcElement can be an element assembly, with IfcElementAssembly as a special focus subtype. In this case it should not be additionally contained in the project spatial hierarchy, i.e.SELF\IfcElement.ContainedInStructure should be NIL.

Geometry Use Definitions The geometric representation of IfcDistributionElement is given by the IfcProductDefinitionShape, allowing multiple geometric representation. Local Placement The local placement for IfcDistributionElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement , which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations The geometric representation of IfcDistributionElement is defined using different geometric representation types for the various subtypes. Only general recommendations are given at the level of the supertype, further constraints are defined at the level of its subtypes.

all occurrences of IfcDistributionElement (and its subtypes) should (whenever possible) share a representation map established by the assigned type. The geometric representation of the occurrence is then an IfcMappedItem. The IfcShapeRepresentation has:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘MappedRepresentation’

The shared geometric representation of the distribution element type (or in some cases of the distribution element) should follow (if applicable) the the following guidelines:

all fixtures (all non distribution flow elements, i.e. everything which is not a duct, a pipe, a cable, or a cable carrier) should be defined by an b-rep geometry. This includes also the complex flow fitting elements (e.g. Y branch or T branch) or distribution flow elements with size changes (e.g. reducer). The IfcShapeRepresentation has:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Brep’

if the geometric model consistency of a b-rep shape representation can not be guaranteed (arcwise connected volume bounded by faces, each being connected, oriented, finite, closed 2-manifold), a surface representation based on open shells should be used. The IfcShapeRepresentation then has:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SurfaceModel’

all “simple” distribution flow elements (general ducts and pipes) are defined by sweep geometry. The IfcShapeRepresentation has:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SweptSolid’

an additional representation type for all “simple” distribution flow elements (general ducts and pipes) is the ability to have a simple line based representation. The IfcShapeRepresentation has:

RepresentationIdentifier : ‘FootPrint’ RepresentationType : ‘GeometricCurveSet’

if only the analytical shape is required for which the exact interpolation between the cross sections is not required, a sectioned spine can be used.

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SectionedSpine’

class IfcDistributionFlowElement : public Ifc2x3::IfcDistributionElement

The distribution element IfcDistributionFlowElement defines occurrence elements of a distribution system that facilitate the distribution of energy or matter, such as air, water or power.

EXAMPLEs of distribution flow elements are ducts, pipes, wires, fittings, and equipment.

HISTORY: New entity in IFC R2.0.

Type Use Definition IfcDistributionFlowElement defines the occurrence of any distribution flow element; common information about distribution flow element types is handled by IfcDistributionFlowElementType. The IfcDistributionFlowElementType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcDistributionFlowElementType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcDistributionFlowElementType has ports or aggregated elements, such objects are reflected at the IfcDistributionFlowElement occurrence using the IfcRelDefinesByObject relationship. Direct instantiation of IfcDistributionFlowElement with IfcObject.ObjectType asserted provides the meaning of a distribution flow element proxy.

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcDistributionFlowElementType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcDistributionFlowElementType.HasPropertySets. If both are given, then the properties directly defined at IfcDistributionFlowElement override the properties defined at IfcDistributionFlowElementType. Refer to the documentation at the supertype IfcDistributionElement and ancestors for inherited property set definitions.

Composition Use Definition The IfcDistributionFlowElement may be decomposed into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcDistributionFlowElement and RelatedObjects contains one or more components. For example, a cable may be decomposed into wires. Standard types for composition are defined at subtypes.

Connection Use Definition The IfcDistributionFlowElement may be connected to other objects as follows using the indicated relationship:

IfcSpatialStructureElement (IfcRelContainedInSpatialStructure) : Indicates the spatial location containing the element. IfcElement (IfcRelConnectsElements) : Indicates physical connectivity with another element (but not embedding or flow transmission), such as a light fixture hanging from a ceiling (IfcCovering), or a junction box having a cover plate (IfcDiscreteAccessory). IfcRelConnectsElements.RelatingElement refers to the anchored side (ceiling for fixture, junction box for cover). IfcElement (IfcRelInterferesElements) : Indicates interference with another element and precedence, such as a pipe going through a wall. IfcOpening (IfcRelFillsElement) : Indicates embedding an element within another element (implying a cutout), such as an air terminal or junction box embedded within a wall. IfcDistributionPort (IfcRelConnectsPortToElement) : Indicates ports on the element which may be connected to other elements for flow distribution of solids, liquids, gas, or electricity. Standard port names, types, and directions are defined at subtypes. IfcDistributionControlElement (IfcRelFlowControlElements) : Indicates a control element that senses or controls some aspect of the flow element, such as a level sensor for a tank or an actuator for a valve.

Assignment Use Definition The IfcDistributionFlowElement may be assigned to the following entities using relationships as indicated:

IfcDistributionSystem (IfcRelAssignsToGroup): Indicates a system containing interconnected devices. IfcPerformanceHistory (IfcRelAssignsToControl): Indicates realtime or historical infomation captured for the device.

The IfcDistributionFlowElement may have assignments of its own using the IfcRelAssignsToProduct relationship where RelatingProduct refers to the IfcDistributionFlowElement and RelatedObjects contains one or more objects of the following types:

IfcTask: Indicates tasks used to purchase, install, renovate, demolish, operate, or otherwise act upon the element. If the element has a type, available task types are assigned to the element type. IfcProcedure: Indicates procedures used to operate the element. If the element has a type, available procedure types are assigned to the element type. IfcEvent: Indicates events raised by the element, sequenced by procedures to be followed. If the element has a type, available event types are assigned to the element type.

Material Use Definition The material of the IfcDistributionFlowElement is defined using one of the following entities:

IfcMaterialProfileSetUsage: For parametric segments, this defines the cross section and alignment to the ‘Axis’ representation, from which the ‘Body’ representation may be generated.

IfcMaterialProfileSet: For non-parametric segments (having fixed length or path), this may define the cross section for analysis purposes, however the ‘Body’ representation is independently generated.

IfcMaterialConstituentSet: For elements containing multiple materials, this indicates materials at named aspects.

IfcMaterial: For elements comprised of a single material, this indicates the material.

The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcDistributionFlowElementType, defining the common attribute data for all occurrences of the same type. Standard names and material types are defined at subtypes.

Representation Use Definition The following shape representations are supported for subtypes of IfcDistributionFlowElement, distinguished by IfcShapeRepresentation.RepresentationIdentifier:

‘Axis’: Represents the 3D flow path of the item having IfcShapeRepresentation.RepresentationType of ‘Curve3D’ and containing a single IfcBoundedCurve subtype such as IfcPolyline, IfcTrimmedCurve, or IfcCompositeCurve. For elements containing directional ports (IfcDistributionPort with FlowDirection of SOURCE or SINK), the direction of the curve indicates direction of flow where a SINK port is positioned at the start of the curve and a SOURCE port is positioned at the end of the curve. This representation is most applicable to flow segments (pipes, ducts, cables), however may be used at other elements to define a primary flow path if applicable.

‘Footprint’: Represents the 2D footprint outline of the item having IfcShapeRepresentation.RepresentationType of ‘GeometricCurveSet’ and containing a single IfcGeometricCurveSet consisting of one or more IfcCurve subtypes such as IfcPolyline, IfcTrimmedCurve, IfcCompositeCurve, or IfcCircle.

‘Body’: Represents the 3D shape of the item having IfcShapeRepresentation.RepresentationType of ‘SurfaceModel’, ‘SolidModel’, or any solid model specializations including ‘Brep’, ‘AdvancedBrep’, ‘SweptSolid’, ‘AdvancedSweptSolid’, ‘CSG’, ‘Clipping’, or ‘SectionedSpine’).

‘Clearance’: Represents the 3D clearance volume of the item having RepresentationType of ‘Surface3D’. Such clearance region indicates space that should not intersect with the ‘Body’ representation of other elements, though may intersect with the ‘Clearance’ representation of other elements. The particular use of clearance space may be for safety, maintenance, or other purpose.

‘Lighting’: Represents the light emission of the item having IfcShapeRepresentation.RepresentationType of ‘LightSource’ and containing one or more IfcLightSource subtypes. This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.

For all representations, if a IfcDistributionFlowElement occurrence is defined by a IfcDistributionFlowElementType having a representation of the same identifier, then ‘MappedRepresentation’ should be used at the occurrence unless overridden.

If materials are defined, geometry of each representation (most typically the ‘Body’ representation) may be organized into shape aspects where styles may be derived by correlating IfcShapeAspect.Name to a corresponding material (IfcMaterialConstituent.Name or IfcMaterialProfile.Name).

Representations are further defined at subtypes; for example, parametric flow segments align material profiles with the ‘Axis’ representation.

IfcMaterial: For elements comprised of a single material, this indicates the material.

The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute.

Representation Use Definition The following shape representations are supported for subtypes of IfcDistributionFlowElementType, distinguished by IfcShapeRepresentation.RepresentationIdentifier:

‘Axis’: Represents the 3D flow path of the item having IfcShapeRepresentation.RepresentationType of ‘Curve3D’ and containing a single IfcBoundedCurve subtype such as IfcPolyline, IfcTrimmedCurve, or IfcCompositeCurve. For elements containing directional ports (IfcDistributionPort with FlowDirection of SOURCE or SINK), the direction of the curve indicates direction of flow where a SINK port is positioned at the start of the curve and a SOURCE port is positioned at the end of the curve.

‘Clearance’: Represents the 3D clearance volume of the item having RepresentationType of ‘Surface3D’. Such clearance region indicates space that should not intersect with the ‘Body’ representation between element occurrences, though may intersect with the ‘Clearance’ representation of other element occurrences. The particular use of clearance space may be for safety, maintenance, or other purpose.

‘Lighting’: Represents the light emission of the item having IfcShapeRepresentation.RepresentationType of ‘LightSource’ and containing one or more IfcLightSource subtypes. This representation is most applicable to lamps and light fixtures, however may be used at other elements that emit light.

class IfcDistributionPort : public Ifc2x3::IfcPort

A distribution port is an inlet or outlet of a product through which a particular substance may flow.

Distribution ports are used for passage of solid, liquid, or gas substances, as well as electricity for power or communications. Flow segments (pipes, ducts, cables) may be used to connect ports across products. Distribution ports are defined by system type and flow direction such that for two ports to be connected, they must share the same system type and have opposite flow directions (one side being a SOURCE and the other being a SINK). Ports are similar to openings in that they do not have any visible geometry; such geometry is captured at the shape representation of the enclosing element or element type. Ports may have shape representations that indicate the position, orientation, and cross-section of the connection.

class IfcDoor : public Ifc2x3::IfcBuildingElement

Definition from ISO 6707-1:1989: Construction for closing an opening, intended primarily for access with hinged, pivoted or sliding operation. The door is a building element that is predominately used to provide controlled access for people and goods. It includes constructions with hinged, pivoted, sliding, and additionally revolving and folding operations. A door consists of a lining and one or several panels. The IfcDoor defines a particular occurrence of a door inserted in the spatial context of a project. A door can:

be inserted as a filler in an opening using the IfcRelFillsElement relationship, then the IfcDoor has an inverse attribute FillsVoids provided,

NOTE View definitions or implementer agreements may restrict the relationship to only include one window (or door) into one opening.

be part of an element assembly, in general an IfcCurtainWall, using the IfcRelAggregates relationship, then the inverse attribute Decomposes is provided. or be a “free standing” door, then the IfcDoor has no inverse attributes FillsVoids or Decomposes provided.

The IFC specification provides two entities for door occurrences:

IfcDoorStandardCase used for all occurrences of doors, that have a ‘Profile’ shape representation defined to which a set of shape parameters for lining and framing properties apply. Additionally it requires the provision of an IfcDoorType that references one IfcDoorLiningProperties and on to many IfcDoorPanelProperties.

NOTE see IfcDoorStandardCase for all specific constraints imposed by this subtype.

IfcDoor used for all other occurrences of doors, particularly for doors having only ‘Brep’, or ‘SurfaceModel’ geometry without applying shape parameters.

The actual parameter of the door and/or its shape are defined by the IfcDoor as the occurrence definition (or project instance), or by the IfcDoorType as the specific definition (or project type). The following parameters are given:

at the IfcDoor or IfcDoorStandardCase for occurrence specific parameters. The IfcDoor specifies:

the door width and height the door opening direction (by the y-axis of the ObjectPlacement)

at the IfcDoorType, to which the IfcDoor is related by the inverse relationship IsDefinedBy pointing to IfcRelDefinesByType, for type parameters common to all occurrences of the same type.

the operation type (single swing, double swing, revolving, etc.) the door hinge side (by using two different styles for right and left opening doors) the construction material type the particular attributes for the lining by the IfcDoorLiningProperties the particular attributes for the panels by the IfcDoorPanelProperties

HISTORY New entity in IFC Release 1.0. IFC2x4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.

Material Use Definition The material of the IfcDoor is defined by the IfcMaterialConstituentSet or as fall back by IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

‘Lining’ - to indicate that the material constituent applies to to the door lining ‘Framing’ - to indicate that the material constituent applies to to the door panel(s), if not provided, the ‘Lining’ material information applied to panel(s) as well ‘Glazing’ - to indicate that the material constituent applies to to the glazing part

If the fall back single IfcMaterial is referenced, it applies to the lining and framing of the door. Property Set Use Definition: The property sets relating to the IfcDoor are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcDoor are part of this IFC release:

Pset_DoorCommon: common property set for all door occurrences Pset_DoorWindowGlazingType: specific property set for the glazing properties of the door glazing, if available Pset_DoorWindowShadingType: specific property set for the shading properties of the door glazing, if available

Quantity Use Definition The quantities relating to the IfcDoor are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to MethodOfMeasurement. Quanties shall be never assigned to the IfcDoorType.

Qto_DoorBaseQuantities: base quantities for all door occurrences.

Containment Use Definition The IfcDoor, as any subtype of IfcBuildingElement, may participate in two different containment relationships as shown in Figure 96. The first (and in most implementation scenarios mandatory) relationship is the hierachical spatial containment, the second (optional) relationship is the aggregation within anelement assembly.

The IfcDoor is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, refering to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes ofIfcSpatialStructureElement are valid spatial containers, with IfcBuildingStorey being the default container. The IfcDoor may be aggregated into an element assembly using the objectified relationship IfcRelAggregates, refering to it by its inverse attribute SELF\IfcObjectDefinition.Decomposes. Doors may be part of an IfcCurtainWall as a special focus subtype. In this case it should not be additionally contained in the project spatial hierarchy, i.e.SELF\IfcElement.ContainedInStructure should be NIL.

NOTE The containment shall be defined independently of the filling relationship, that is, even if the IfcDoor is a filling of an opening established by IfcRelFillsElement, it is also contained in the spatial structure by an IfcRelContainedInSpatialStructure.

Figure 96 — Door containment

Geometry Use Definitions: The geometric representation of IfcDoor is given by the IfcProductDefinitionShape, allowing multiple geometric representations. The IfcDoor, in case of an occurrance object, gets its parameter and shape from the IfcDoorType. If an IfcRepresentationMap (a block definition) is defined for the IfcDoorType, then the IfcDoor inserts it through the IfcMappedItem. Local Placement The local placement for IfcDoor is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point to the local placement of the same element (if given), in which the IfcDoor is used as a filling (normally an IfcOpeningElement), as provided by the IfcRelFillsElement relationship. If the IfcDoor is not inserted into an IfcOpeningElement, then the PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement that is used in the ContainedInStructure inverse attribute or to a referenced spatial structure element at a higher level. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representation Thegeometric representation of IfcDoor is defined using the following (potentiallymultiple) IfcShapeRepresentation’s for its IfcProductDefinitionShape:

Profile: A’Curve3D’ consisting of a single losed curve defining the outer boundary of the door (lining). The door parametric representation uses this profile in order to apply the door lining and panel parameter. If not provided, the profile of the IfcOpeningElement is taken. FootPrint: A ‘GeometricCurveSet’, or ‘Annotation2D’ representation defining the 2D shape of the door Body: A ‘SweptSolid’, ‘SurfaceModel’, or ‘Brep’ representation defining the 3D shape of the door.

In addition the parametric representation of a (limited) door shape is available by applying the parameters from IfcDoorType referencing IfcDoorLiningProperties and IfcDoorPanelProperties. The purpose of the parameter is described at those entities and below (door opening operation by door type). Profile -‘Curve3D’ representation The door profile is represented by a three-dimensional closed curve within a particular shape representation. The profile is used to apply the parameter of the parametric door representation.The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Profile’ RepresentationType : ‘Curve3D’, only a single closed curve shall be contained in the set of IfcShapeRepresentation.Items.

A ‘Profile’ representation has to be provided if:

a parametric representation shall be applied to the door AND

thedoor is ‘free standing’, or the opening into which thedoor is inserted is not extruded horizontally (i.e. where the opening profile does not match thedoor profile)

FootPrint -‘GeometricCurveSet’ or ‘Annotation2D’ representation The door foot print is represented by a set of two-dimensionalcurves (or in case of ‘Annotation2D’ additional hatching and text) within a particular shape representation. The foot print is used for the planview representation of the door.The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘FootPrint’ RepresentationType : ‘GeometricCurveSet’, or ‘Annotation2D’

Body - ‘SweptSolid’, ‘SurfaceModel’, or ‘Brep’ representation The door body is either represented parameterically (see parametric representation) or by explicit 3D shape. The 3D shape is given by using extrusion geometry, or surface models, or Brep models within a particular shape representation. The body is used for the model view representation of the door.The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SweptSolid’, ‘SurfaceModel’, or ‘Brep’

MappedRepresentation The ‘FootPrint’ and ‘Body’ geometric representation of IfcDoor can be shared among several identical doors using the ‘MappedRepresentation’. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘FootPrint’, ‘Body’ RepresentationType : ‘MappedRepresentation’

The same constraints, as given for the ‘FootPrint’, ‘Body’ representation identifiers, shall apply to the MappedRepresentation of the IfcRepresentationMap. Parameteric Representation using parameters at IfcDoorType The parameters that defines the shape of the IfcDoor, are given at the IfcDoorType and the property sets, which are included in the IfcDoorType. The IfcDoor only defines the local placement which determines the opening direction of the door. The overall size of the IfcDoor to be used to apply the lining or panel parameter provided by the IfcDoorType is determined by the IfcShapeRepresentation with the RepresentationIdentifier = ‘Profile’. Only in case of an IfcDoor inserted into an IfcOpeningElement using the IfcRelFillsElement relatioship, having a horizontal extrusion (along the y-axis of the IfcDoor), the overall size is determined by the extrusion profile of the IfcOpeningElement. NOTE The OverallWidth and OverallHeight parameters are for informational purpose only. The opening direction is determined by the local placement of IfcDoor and the OperationType of the door style as shown in Figure 97. NOTE There are different definitions in various countries on what a left opening or left hung or left swing door is (same for right). Therefore the IFC definition may derivate from the local standard and need to be mapped appropriately.

Opening directions

Definitions Reference to other standards

The door panel (for swinging doors) opens always into the direction of the positive Y axis of the local placement. The determination of whether the door opens to the left or to the right is done at the level of the IfcDoorType. Here it is a left side opening door given byIfcDoorType.OperationType = SingleSwingLeft refered to as LEFT HAND (LH) in US *

refered to as DIN-R (right hung) in Germany

If the door should open to the other side, then the local placement has to be changed. It is still a left side opening door, given by IfcDoorType.OperationType = SingleSwingLeft refered to as RIGHT HAND REVERSE (RHR) in US *

refered to as DIN-R (right hung) in Germany

If the door panel (for swinging doors) opens to the right, a separate door style needs to be used (here IfcDoorTypee.OperationType = SingleSwingRight) and it always opens into the direction of the positive Y axis of the local placement. refered to as RIGHT HAND (RH) in US *

refered to as DIN-L (left hung) in Germany

If the door panel (for swinging doors) opens to the right, and into the opposite directions, the local placement of the door need to change. The door style is given by IfcDoorType.OperationType = SingleSwingRight. refered to as LEFT HAND REVERSE (LHR) in US *

refered to as DIN-L (left hung) in Germany

class IfcDoorLiningProperties : public Ifc2x3::IfcPropertySetDefinition

The door lining is the frame which enables the door leaf to be fixed in position. The door lining is used to hang the door leaf. The parameters of the door lining (IfcDoorLiningProperties) define the geometrically relevant parameter of the lining.

NOTE The IfcDoorLiningProperties shall only be applied to construct the 3D shape of a door, if the attribute IfcDoorStyle.ParameterTakesPrecedence is set TRUE.

The IfcDoorLiningProperties are included in the list of properties of IfcDoorStyle.HasPropertySets. More information about the door lining can be included in the same list of the IfcDoorStyle using another IfcPropertySet for dynamic extensions.

HISTORY New entity in IFC Release 2.0. Has been renamed from IfcDoorLining in IFC Release 2x.

IFC2x4 CHANGE The following attributes have been added LiningToPanelOffsetX, LiningToPanelOffsetY. The attribute ShapeAspectStyle is deprecated and shall no longer be used. Supertype changed to new IfcPreDefinedPropertySet.

Geometry use definitions The IfcDoorLiningProperties does not hold its own geometric representation. However it defines parameters which can be used to create the shape of the door style (which is inserted by the IfcDoor into the spatial context of the project) as shown in Figure 172. The parameters of the IfcDoorLiningProperties define a standard door lining, including (if given) a threshold and a transom. The outer boundary of the lining is determined by the occurrence parameter assigned to the IfcDoor, which inserts the IfcDoorStyle.

The lining is applied to the left, right and upper side of the opening reveal. The parameters are:

LiningDepth, if omited, equal to wall thickness - this only takes effect if a value for LiningThickness is given. If both parameters are not given, then there is no lining. LiningThickness LiningToPanelOffsetX LiningToPanelOffsetY

NOTE Parameters added in IFC2x4.

The lining can only cover part of the opening reveal.

LiningOffset : given if lining edge has an offset to the x axis of the local placement.

NOTE In addition to theLiningOffset, the local placement of the IfcDoor can already have an offset to the wall edge and thereby shift the lining along the y axis. The actual position of the lining is calculated from the origin of the local placement along the positive y axis with the distance given by LiningOffset.

The lining may include a casing, which covers part of the wall faces around the opening. The casing covers the left, right and upper side of the lining on both sides of the wall. The parameters are:

CasingDepth CasingThickness

The lining may include a threshold, which covers the bottom side of the opening. The parameters are:

ThresholdDepth if omited, equal to wall thickness - this only takes effect if a value for ThresholdThickness is given. If both parameters are not given, then there is no threshold. ThresholdThickness ThresholdOffset (not shown in figure): given, if the threshold edge has an offset to the x axis of the local placement.

The lining may have a transom which separates the door panel from a window panel. The transom, if given, is defined by:

TransomOffset : a parallel edge to the x axis of the local placement TransomThickness

The depth of the transom is identical to the depth of the lining and not given as separate parameter.

Figure 172 — Door lining properties

NOTE LiningDepth describes the length of the lining along the reveal of the door opening. It can be given by an absolute value if the door lining has a specific depth depending on the door style. However often it is equal to the wall thickness. If the same door style is used (like the same type of single swing door), but inserted into different walls with different thicknesses, it would be necessary to create a special door style for each wall thickness. Therefore several CAD systems allow to set the value to “automatically aligned” to wall thickness. This should be exchanged by leaving the optional attribute LiningDepth unassigned. The same agreement applies to ThresholdDepth.

class IfcDoorPanelProperties : public Ifc2x3::IfcPropertySetDefinition

A door panel is normally a door leaf that opens to allow people or goods to pass. The parameters of the door panel define the geometrically relevant parameter of the panel,

The IfcDoorPanelProperties are used to parametrically describe the shape and operation of door panels. The parametric definition can be added solely or additionally to the explicit shape representation of the door.

The IfcDoorStyle can define doors consisting of more then one panel. In this case, one instance of IfcDoorPanelProperties has to be included for each door panel. The PanelPosition attribute, in conjunction with the IfcDoorStyle.OperationType attribute, determines to which panel the IfcDoorPanelProperties apply. The IfcDoorPanelProperties are included in the list of properties , given by attribute HasPropertySets of the IfcDoorStyle. More information about the door panel can be included in the same list of the IfcDoorStyle using the IfcPropertySet for dynamic extensions.

HISTORY New Entity in IFC Release 2.0.

IFC2x4 CHANGE Supertype changed to new IfcPreDefinedPropertySet.

Geometry use definitions

The IfcDoorPanelProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the door style (which is inserted by the IfcDoor into the spatial context of the project) as shown in Figure 173. The parameters of the IfcDoorPanelProperties define a standard door panel, including (if given) a proportional width to define non-uniform double swing (or sliding, or folding) doors. The outer boundary of the panel is determined by the occurrence parameter assigned to the IfcDoor, which inserts the IfcDoorStyle. It has to take the lining parameter into account as well.

The depth of the panel (swinging, double-acting, and sliding panels) is defined by the PanelDepth parameter.

PanelDepth

For door operation types that include more than one panel, the width of (at least) one panel is given by a normalised ratio measure. It determines the width of that panel, which is defined as a ratio of the overall width of the door opening.

class IfcDoorStyle : public Ifc2x3::IfcTypeProduct

Definition: The door style, IfcDoorStyle, defines a particular style of doors, which may be included into the spatial context of the building model through instances of IfcDoor. A door style defines the overall parameter of the door style and refers to the particular parameter of the lining and one (or several) panels through the IfcDoorLiningProperties and the IfcDoorPanelProperties.

The door entity, IfcDoor, defines a particular occurrence of a door inserted in the spatial context of a project. The actual parameter of the door and/or its shape is defined at the IfcDoorStyle, to which the IfcDoor is related by the inverse relationship IsDefinedBy pointing to IfcRelDefinedByType. The IfcDoorStyle also defines the particular attributes for the lining, IfcDoorLiningProperties, and panels, IfcDoorPanelProperties.

HISTORYNew entity in IFC Release 2x.

IFC2x4 CHANGE The entity is deprecated and shall not be used. The new entity IfcDoorType shall be used instead.

Geometry use definitions

The IfcDoorStyle defines the baseline geometry, or the representation map, for all occurrences of the door style, given by the IfcDoor, pointing to this style. The representation of the door style may be given by the agreed set of minimal parameters, defined for the door lining and the door panel(s), or it may be given by a geometric representation used by the IfcRepresentationMap. The attribute ParameterTakesPrecedence decides, whether the set of parameters can be used to exactly represent the shape of the door style (TRUE), or whether the attached IfcRepresentationMap holds the exact representation (FALSE).

The IfcDoorStyleOperationTypeEnum defines the general layout of the door style. Depending on the enumerator, the appropriate instances of IfcDoorLiningProperties and IfcDoorPanelProperties are attached in the list of HasPropertySets. The IfcDoorStyleOperationTypeEnum mainly determines the hinge side (left hung, or right hung), the operation (swinging, sliding, folding, etc.)and the number of panels.

See geometry use definitions at IfcDoorStyleOperationTypeEnum for the correct usage of opening symbols for different operation types.

ENTRY: Entry fitting, typically unconnected at one port and connected to a flow distribution system at the other (e.g., an outside air duct system intake opening). EXIT: Exit fitting, typically unconnected at one port and connected to a flow distribution system at the other (e.g., an exhaust air discharge opening). JUNCTION: A fitting with typically more than two ports used to redistribute flow among the ports and/or to change the direction of flow between connected elements (e.g, tee, cross, wye, etc.). OBSTRUCTION: A fitting with typically two ports used to obstruct or restrict flow between the connected elements (e.g., screen, perforated plate, etc.). TRANSITION: A fitting with typically two ports having different shapes or sizes. Can also be used to change the direction of flow between connected elements. USERDEFINED: User-defined fitting. NOTDEFINED: Undefined fitting.

class IfcEdge : public Ifc2x3::IfcTopologicalRepresentationItem

Definition from ISO/CD 10303-42:1992: An edge is the topological construct corresponding to the connection of two vertices. More abstractly, it may stand for a logical relationship between two vertices. The domain of an edge, if present, is a finite, non-self-intersecting open curve in RM, that is, a connected 1-dimensional manifold. The bounds of an edge are two vertices, which need not be distinct. The edge is oriented by choosing its traversal direction to run from the first to the second vertex. If the two vertices are the same, the edge is a self loop. The domain of the edge does not include its bounds, and 0 ≤ Ξ ≤ ∞. Associated with an edge may be a geometric curve to locate the edge in a coordinate space; this is represented by the edge curve (IfcEdgeCurve) subtype. The curve shall be finite and non-self-intersecting within the domain of the edge. An edge is a graph, so its multiplicity M and graph genus Ge may be determined by the graph traversal algorithm. Since M = E = 1, the Euler equation (1) reduces in the case to

where V = 1 or 2, and Ge = 1 or 0. Specifically, the topological edge defining data shall satisfy:

• an edge has two vertices

• the vertices need not be distinct

• Equation (2) shall hold.

The geometry between the two vertices defaults to a straight line if no curve geometry is assigned using the subtype IfcEdgeCurve. The IfcEdge can therefore be used to exchange straight edges without an associated geometry provided by IfcLine or IfcPolyline thought IfcEdgeCurve.EdgeGeometry.

Figure 333 illustrates an example where the bounds of the IfcEdge are given by the EdgeStart and EdgeEnd; this also determines the direction of the edge. The location within a coordinate space is determined by the IfcVertexPoint type for EdgeStart and EdgeEnd. Since no edge geometry is assigned, it defaults to a straight line agreeing to the direction sense.

class IfcEdgeCurve : public Ifc2x3::IfcEdge

Definition from ISO/CD 10303-42:1992: An edge curve is a special subtype of edge which has its geometry fully defined. The geometry is defined by associating the edge with a curve which may be unbounded. As the topological and geometric directions may be opposed, an indicator (same sense) is used to identify whether the edge and curve directions agree or are opposed. The Boolean value indicates whether the curve direction agrees with (TRUE) or is in the opposite direction (FALSE) to the edge direction. Any geometry associated with the vertices of the edge shall be consistent with the edge geometry. Multiple edges can reference the same curve.

Figure 334 illustrates an example where the edge geometry is given by an unbounded curve, here IfcCircle. The bounds are provided by the EdgeStart and EdgeEnd, the topological direction of the IfcEdgeCurve opposes the direction of the IfcCircle by SameSense = FALSE.

class IfcElement : public Ifc2x3::IfcProduct

Definition from IAI: Generalization of all components that make up an AEC product. Those elements can be logically contained by a spatial structure element that constitutes a certain level within a project structure hierarchy (e.g., site, building, storey or space). This is done by using the IfcRelContainedInSpatialStructure relationship. Elements are physically existent objects, although they might be void elements, such as holes. Elements either remain permanently in the AEC product, or only temporarily, as formwork does. Elements can be either assembled on site or pre-manufactured and built in on site. EXAMPLEs of elements in a building construction context are walls, floors, windows and recesses. An element can have material and quantity information assigned through the IfcRelAssociatesMaterial and IfcRelDefinesByProperties relationship. In addition an element can be declared to be a specific occurrence of an element type (and thereby be defined by the element type properties) using the IfcRelDefinesByType relationship. An element can also be defined as an element assembly that is a group of semantically and topologically related elements that form a higher level part of the AEC product. Those element assemblies are defined by virtue of the IfcRelAggregates relationship. EXAMPLEs for element assembly are complete Roof Structures, made by several Roof Areas, or a Stair, composed by Flights and Landings. Elements that performs the same function may be grouped by an “Element Group By Function”. It is realized by an instance of IfcGroup with the ObjectType = ‘ElementGroupByFunction”. HISTORY New entity in IFC Release 1.0 Property Set Use Definition: The property sets relating to the IfcElement are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. Quantity Use Definition: The quantities relating to the IfcElement are defined by the IfcElementQuantity and attached by the IfcRelDefinesByProperties. A detailed specification for individual quantities is introduced at the level of subtypes of IfcElement. Geometry Use Definitions The geometric representation of any IfcElement is given by the IfcProductDefinitionShape and IfcLocalPlacement allowing multiple geometric representations. A detailed specification for the local placement and shape representaion is introduced at the level of subtypes of IfcElement.

class IfcElementAssembly : public Ifc2x3::IfcElement

The IfcElementAssembly represents complex element assemblies aggregated from several elements, such as discrete elements, building elements, or other elements. EXAMPLE Steel construction assemblies, such as trusses and different kinds of frames, can be represented by the IfcElementAssembly entity. Other examples include slab fields aggregated from a number of precast concrete slabs or reinforcement units made from several reinforcement bars. Also bathroom units, staircase sections and other premanufactured or precast elements are examples of the general IfcElementAssembly entity NOTE The IfcElementAssembly is a general purpose entity that is required to be decomposed. Also other subtypes of IfcElement can be decomposed, with some dedicated entities such as IfcWallElementedCase and IfcSlabElementedCase. The assembly structure can be nested, i.e. an IfcElementAssembly could be an aggregated part within another IfcElementAssembly. NOTE View definitions and/or implementer agreements may restrict the number of allowed levels of nesting. HISTORY New Entity for Release IFC2x Edition 2.

Containment Use Definition The IfcElementAssembly should have (and in most implementation scenarios it is mandatory) a relationship for its hierachical containment in the spatial structure of the project.

The IfcElementAssembly is places within the project spatial hierarchy using the objectified relationship IfcRelContainedInSpatialStructure, refering to it by its inverse attribute SELF\IfcElement.ContainedInStructure. Subtypes of IfcSpatialStructureElement are valid spatial containers, with IfcBuildingStorey being the default container.

The IfcElementAssembly shall represent an aggregate, i.e. it should have other elements, being subtypes of IfcElement, as contained (sub)parts.

The IfcElementAssembly is an aggregate i.e. being composed by other elements and acting as an assembly using the objectified relationship IfcRelAggregates, refering to it by its inverse attribute SELF\IfcObjectDefinition.IsDecomposedBy. Components of an assembly are described by instances of subtypes of IfcElement. In this case, the containedsubtypes of IfcElement shall not be additionally contained in the project spatial hierarchy, i.e. the inverse attribute SELF\IfcElement.ContainedInStructure of those IfcElement’s shall be NIL.

Figure 27 illustrates spatial containment and element aggregation relationships.

Figure 27 — Element assembly containment

Geometry Use Definitions The geometric representation of IfcElementAssembly is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Local Placement The local placement for IfcElementAssembly is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement that is used in the ContainedInStructure inverse attribute or to a referenced spatial structure element at a higher level. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations The geometry of an IfcElementAssembly is generally formed from its components, in which case it does not need to have an explicit geometric representation. In some cases it may be useful to also expose an own explicit representation of the aggregate. NOTE View definitions or implementer agreements may further constrain the applicability of certain shape representations at the IfcElementAssembly in respect of the shape representations of its parts. Informal proposition

The IfcElementAssembly shall have an aggregation relationship to the contained parts, i.e. the (INV) IsDecomposedBy relationship shall be utilzed.

It is often desirable to model a number of same-shaped element components by means of a single occurrence object, e.g. several bolts within a connection or a row of reinforcement elements. In this IFC release, this is possible by means of multiple mapped representation as documented below.

To express the multiplicity of element components also on a higher semantic level, an IfcElementQuantity should be provided via IfcRelDefinesByProperties. The quantity should contain an IfcQuantityCount named ‘Count’ with the number of components.

Geometry Use Definition

The geometric representation of IfcElementComponent is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are:

Local Placement The local placement for IfcElementComponent is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcElement or IfcElementAssembly, which is used in the Decomposes inverse attribute, i.e. the local placement is defined relative to the local placement of the element or element assembly in which the component is contained. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Surface Model Representation

Any IfcElementComponent (if no further constraints are defined at the level of its subtypes) may be represented as a single or multiple surface models, based on either shell or face based models. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘SurfaceModel’

Brep Representation

Any IfcElementComponent (if no further constraints are defined at the level of its subtypes) may be represented as a single or multiple Boundary Representation elements (which are restricted to faceted Brep with or without voids). The Brep representation allows for the representation of complex element shape. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Brep’

Mapped Representation

The mapped item, IfcMappedItem, should be used if appropriate as it allows for reusing the geometry definition of a type at occurrences of the same type. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘MappedRepresentation’

Multiple Mapped Representation

A single instance of a subtype of IfcElementComponent can stand for several actual element components at once. In this case, the IfcShapeRepresentation contains as many mapped items as there are element components combined within this occurrence object:

Figure 151 illustrates multiple components modeled as a single occurrence object (here: IfcFastener)

Figure 151 — Element component mapped representation

Representation identifier and type are the same as in single mapped representation. The number of mapped items in the representation corresponds with the count of element components in the IfcElementQuantity.

class IfcElementQuantity : public Ifc2x3::IfcPropertySetDefinition

Definition from IAI: An IfcElementQuantity defines a set of derived measures of an element’s physical property. Elements could be spatial structure elements (like buildings, storeys, or spaces) or building elements (like walls, slabs, finishes). The IfcElementQuantity gets assigned to the element by using the IfcRelDefinesByProperties relationship. The optional MethodOfMeasurement attribute defines the code, e.g. from a standard method of measurement, which had been used to calculate the element quantity.

NOTE The recognizable values for the name and the method of measurement attributes have to be agreed upon in further agreement documents, such as implementers agreements. Some of these agreements might be limited to a certain region, to which the method of measurement applies.

The name attribute, given at the individual Quantities provides a recognizable semantic meaning of the element quantity. Both information is needed to establish a precise meaning for the measure value. An optional description may be assigned to each of the Quantities. All quantities assigned by a single instance of IfcElementQuantity are deemed to have been generated according to the same method of measurement. However several instances of IfcElementQuantity are assignable to an element, thus allowing for an element having quantities generated according to several methods of measurement.

EXAMPLE1 To exchange the net floor area of spaces in the German region (as IfcSpace), the name might be ‘Netto-Grundfläche’ (net floor area), and the method of measurement might be accordingly ‘DIN277-2’ (German industry norm no. 277 edition 2)

EXAMPLE2 The same instance of IfcSpace may have a different area measure assigned in the German region according to a housing regulation, the name would be ‘Wohnfläche’ and the method of measurement would be ‘2.BV’. It would be attached to the IfcSpace by a separate IfcRelDefinesByProperties relationship.

The IfcElementQuantity can have the following subtypes of IfcPhysicalQuantity within its SET of Quantities, which count for the basis measure types used:

count measure weight measure length measure area measure volume measure time measure

HISTORY New entity in IFC Release 2x. NOTE: It replaces the calcXxx attributes used in previous IFC Releases. IFC2x4 CHANGE Subtyped from new intermediate IfcPreDefinedPropertySet supertype.

Quantity Use Defintion Base quantities are quantity definitions that are independent of a particular method of measurement and therefore internationally applicable. Base quantities are defined as gross and net values and provided by measurement of the correct geometric shape representation of the element. The IFC specification includes a set of base quantity definition. See each subtype of IfcElement for applicable base quantities. The following general agreements apply for each base quantity set

IfcElementQuantity.Name = ‘BaseQuantities’ IfcElementQuantity.MethodOfMeasurement = NIL IfcElementQuantity.Quantities = SET of subtypes of IfcPhysicalSimpleQuantity with values for the Name attribute as published as part of the IFC specifciation.

IfcEllipseProfileDef defines an ellipse as the profile definition used by the swept surface geometry or the swept area solid. It is given by its semi axis attributes and placed within the 2D position coordinate system, established by the Position attribute.

HISTORY New entity in IFC2x

Figure 317 illustrates parameters for the ellipse profile definition. The parameterized profile defines its own position coordinate system. The underlying coordinate system is defined by the swept surface or swept area solid that uses the profile definition. It is the xy plane of either:

IfcSweptSurface.Position IfcSweptAreaSolid.Position

Or in case of sectioned spines it is the xy plane of each list member of IfcSectionedSpine.CrossSectionPositions. By using offsets of the position location, the parameterized profile can be positioned centric (using x,y offsets = 0.), or at any position relative to the profile. Explicit coordinate offsets are used to define cardinal points (for example, upper-left bound). The location of the position coordinate system defines the center of the ellipse. The SemiAxis1 attribute defines the first radius of the ellipse in the direction of the X axis, the SemiAxis2 attribute defines the second radius of the ellipse in the direction of the Y axis.

NOTE The semi axes of the ellipse are rectangular to each other by definition.

DIRECTEVAPORATIVEPACKAGEDROTARYAIRCOOLER: Direct evaporative packaged rotary air cooler: Cools the air stream by evaporating water dircectly into the air stream using coolers that wet and wash the evaporative pad by rotating it through a water bath. DIRECTEVAPORATIVEAIRWASHER: Direct evaporative air washer: Cools the air stream by evaporating water dircectly into the air stream using coolers with spray-type air washer consist of a chamber or casing containing spray nozzles, and tank for collecting spray water, and an eliminator section for removing entrained drops of water from the air. INDIRECTEVAPORATIVEPACKAGEAIRCOOLER: Indirect evaporative package air cooler: Cools the air stream by evaporating water indirectly and without adding moisture into the air stream. On one side of the heat exchanger, the secondary air stream is cooled by evaporation, while on the other side of heat exchanger, the primary air stream (conditioned air to be supplied to the room) is sensibly cooled by the heat exchanger surfaces. INDIRECTEVAPORATIVEWETCOIL: Indirect evaporative wet coil: Cools the air stream by evaporating water indirectly and without adding moisture into the air stream. Water is sprayed directly on the tubes of the heat exchanger where latent cooling takes place and the vaporization of the water on the outside of the heat exchanger tubes allows the simultaneous heat and mass transfer which removes heat from the supply air on the tube side. INDIRECTEVAPORATIVECOOLINGTOWERORCOILCOOLER: Indirect evaporative cooling tower or coil cooler: Cools the air stream by evaporating water indirectly and without adding moisture into the air stream using a combination of a cooling tower or other evaporative water cooler with a water-to-air heat exchanger coil and water circulating pump. INDIRECTDIRECTCOMBINATION: Indirect/Direct combination: Cools the air stream by evaporating water indirectly and without adding moisture into the air stream using a two-stage cooler with a first-stage indirect evaporative cooler and second-stage direct evaporative cooler.

class IfcEvaporatorType : public Ifc2x3::IfcEnergyConversionDeviceType

The energy conversion device type IfcEvaporatorType defines commonly shared information for occurrences of evaporators. The set of shared information may include:

common properties with shared property sets common representations of shape common materials common composition of elements common ports applicable assignment of process types

It is used to define a evaporator specification (i.e. the specific product information, that is common to all occurrences of that product type). Evaporator types may be exchanged without being already assigned to occurrences. Occurrences of IfcEvaporatorType are represented by instances of IfcEvaporator.

HISTORY: New entity in IFC2x2

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the HasPropertySets attribute. Refer to the documentation at the supertype IfcEnergyConversionDeviceType and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_EvaporatorTypeCommon

Material Use Definition The material of the IfcEvaporatorType is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

‘Refrigerant’: Refrigerant material.

Port Use Definition The distribution ports relating to the IfcEvaporatorType type are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. Ports are reflected at occurrences of this type using the IfcRelDefinesByObject relationship. Refer to the documentation at IfcEvaporator for standard port definitions.

class IfcExtrudedAreaSolid : public Ifc2x3::IfcSweptAreaSolid

The IfcExtrudedAreaSolid is defined by sweeping a cross section provided by a profile definition. The direction of the extrusion is given by the ExtrudedDirection attribute and the length of the extrusion is given by the Depth attribute. If the planar area has inner boundaries (holes defined), then those holes shall be swept into holes of the solid. The extruded direction can be any direction which is not perpendicular to the z axis of the position coordinate system of the profile. The following definitions from ISO 10303-42 apply:

An extruded area solid is a solid defined by sweeping a bounded planar surface. The direction of translation is defined by a direction vector, and the length of the translation is defined by a distance depth. The planar area may have holes which will sweep into holes in the solid.

The ExtrudedDirection is given within the position coordinate system as defined by IfcSweptAreaSolid.Position. Extrusions are not restricted to be perpendicular to the extruded surface of the profile.

Figure 255 illustrates geometric parameters of the extruded area solid. The extruded area solid defines the extrusion of a 2D area (given by a profile definition) by an direction and depth. The result is a solid. The swept area is given by a profile definition. This profile is defined:

as a 2D bounded curve within the xy plane of the position coordinate system, as a 2D bounded curve with holes within the xy plane of the position coordinate system, or as a 2D primitive, defined within a 2D position coordinate system, that is placed relative to the xy plane of the position coordinate system

NOTE Corresponding ISO 10303-42 entity: extruded_area_solid. Please refer to ISO/IS 10303-42:1994, p. 183 for the final definition of the formal standard. The data type of the inherited SweptArea attribute is different, i.e. of type IfcProfileDef. The Position attribute has been added to position the cross section used for the linear extrusion.

HISTORY New entity in IFC Release 1.5, capabilities of this entity have been enhanced in IFC Release 2x.

Texture use definition For side faces, textures are aligned facing upright continuously along the sides with origin at the first point of an arbitrary profile, and following the outer bound of the profile counter-clockwise (as seen from above). For parameterized profiles, the origin is defined at the +Y extent for rounded profiles (having no sharp edge) and the first sharp edge counter-clockwise from the +Y extent for all other profiles. Textures are stretched or repeated on each side along the outer boundary of the profile according to RepeatS. Textures are stretched or repeated on each side along the extrusion axis according to RepeatT. For top and bottom caps, textures are aligned facing front-to-back, with the origin at the minimum X and Y extent. Textures are stretched or repeated on the top and bottom to the extent of each face according to RepeatS and RepeatT. For profiles with voids, textures are aligned facing upright along the inner side with origin at the first point of an arbitrary profile, and following the inner bound of the profile clockwise (as seen from above). For parameterized profiles, the origin of inner sides is defined at the +Y extent for rounded profiles (having no sharp edge such as hollow ellipses or rounded rectangles) and the first sharp edge clockwise from the +Y extent for all other profiles.

Figure 256 illustrates default texture mapping with a repeated texture (RepeatS=True and RepeatT=True). The image on the left shows the texture where the S axis points to the right and the T axis points up. The image on the right shows the texture applied to the geometry where the X axis points back to the right, the Y axis points back to the left, and the Z axis points up. For an IfcExtrudedAreaSolid having a profile of IfcIShapeProfileDef, the side texture coordinate origin is the first corner counter-clockwise from the +Y axis, which equals (-0.5*IfcIShapeProfileDef.OverallWidth, +0.5*IfcIShapeProfileDef.OverallDepth), while the top (end cap) texture coordinates start at (-0.5*IfcIShapeProfileDef.OverallWidth, -0.5*IfcIShapeProfileDef.OverallDepth).

class IfcFace : public Ifc2x3::IfcTopologicalRepresentationItem

Definition from ISO/CD 10303-42:1992: A face is a topological entity of dimensionality 2 corresponding to the intuitive notion of a piece of surface bounded by loops. Its domain, if present, is an oriented, connected, finite 2-manifold in Rm. A face domain shall not have handles but it may have holes, each hole bounded by a loop. The domain of the underlying geometry of the face, if present, does not contain its bounds, and 0 < Ξ < ∞. A face is represented by its bounding loops, which are defined as face bounds. A face has a topological normal n and the tangent to a loop is t. For a loop bounding a face with defined geometry, the cross product n x t points toward the interior of the face. That is, each loop runs counter-clockwise around the face when viewed from above, if we consider the normal n to point up. With each loop is associated a BOOLEAN flag to signify whether the loop direction is oriented with respect to the face normal (TRUE) or should be reversed (FALSE).

A face shall have at least one bound, and the loops shall not intersect. One loop is optionally distinguished as the outer loop of the face. If so, it establishes a preferred way of embedding the face domain in the plane, in which the other bounding loops of the face are inside the outer bound. Because the face domain is arcwise connected, no inner loop will contain any other loop. This is true regardless of which embedding in the plane is chosen.

The edges and vertices referenced by the loops of a face form a graph, of which the individual loops are the connected components. The Euler equation (1) for this graph becomes:

where Gli is the graph genus of the i th loop.

NOTE Corresponding ISO 10303 entity: face. No subtypes of face have been incorporated into this IFC Release. Please refer to ISO/IS 10303-42:1994, p. 140 for the final definition of the formal standard. The WR1 has not been incorporated, since it is always satisfied, due to the fact that only poly loops exist for face bounds.

HISTORY New class in IFC Release 1.0

Informal propositions:

No edge shall be referenced by the face more than twice.

Distinct face bounds of the face shall have no common vertices. If geometry is present, distinct loops of the same face shall not intersect.

The face shall satisfy the Euler Equation: (number of vertices) - (number of edges) - (number of loops) + (sum of genus for loops) = 0.

Definition from ISO/CD 10303-42:1992: A face surface (IfcFaceSurface) is a subtype of face in which the geometry is defined by an associated surface. The portion of the surface used by the face shall be embeddable in the plane as an open disk, possibly with holes. However, the union of the face with the edges and vertices of its bounding loops need not be embeddable in the plane. It may, for example, cover an entire sphere or torus. As both a face and a geometric surface have defined normal directions, a BOOLEAN flag (the orientation attribute) is used to indicate whether the surface normal agrees with (TRUE) or is opposed to (FALSE) the face normal direction. The geometry associated with any component of the loops of the face shall be consistent with the surface geometry, in the sense that the domains of all the vertex points and edge curves are contained in the face geometry surface. A surface may be referenced by more than one face surface.

NOTE Corresponding ISO 10303 entity: face_surface. Please refer to ISO/IS 10303-42:1994, p. 204 for the final definition of the formal standard.

HISTORY New class in IFC2x

Informal propositions:

The domain of the face surface is formally defined to be the domain of its face geometry as trimmed by the loops, this domain does not include the bounding loops. A face surface has non zero finite extent. A face surface is a manifold. A face surface is arcwise connected. A face surface has surface genus 0. The loops are not part of the face domain. Loop geometry shall be consistent with face geometry. This implies that any edge - curves or vertex points used in defining the loops bounding the face surface shall lie on the face geometry.

Definition from ISO/CD 10303-42:1992: A faceted B-rep is a simple form of boundary representation model in which all faces are planar and all edges are straight lines. Unlike the B-rep model, edges and vertices are not represented explicitly in the model but are implicitly available through the poly loop entity. A faceted B-rep has to meet the same topological constraints as the manifold solid B-rep.

NOTE The faceted B-rep has been introduced in order to support the larger number of systems that allow boundary type solid representations with planar surfaces only.

NOTE Corresponding ISO 10303-42 entity: faceted_brep. Please refer to ISO/IS 10303-42:1994, p. 173 for the final definition of the formal standard. In the current IFC Release faceted B-rep with voids is represented by an own subtype and not defined via an implicit ANDOR supertype constraint as in ISO/IS 10303-42:1994. This change has been made due to the fact, that only ONEOF supertype constraint is allowed within the IFC data schema.

HISTORY New entity in IFC Release 1.0

Informal proposition:

All the bounding loops of all the faces of all the shells in the IfcFacetedBrep shall be of type IfcPolyLoop. All vertices shall be referenced by all polyloops, sharing the vertex. That is, each Cartesian point shall be referenced by at least three polyloops.

Figure 257 illustrates use of IfcFacetedBrep for boundary representation models with planar surfaces only. The diagram shows the topological and geometric representation items that are used for faceted breps. Each IfcCartesianPoint, used within the IfcFacetedBrep shall be referenced three times by an IfcPolyLoop bounding a different IfcFace.

class IfcFeatureElement : public Ifc2x3::IfcElement

Definition from IAI: Generalization of all existence dependent elements which modify the shape and appearance of the associated master element. The IfcFeatureElement offers the ability to handle shape modifiers as semantic objects within the IFC object model.

NOTE The term “feature” has a predefined meaning in a context of “feature-based modeling” and within steel construction work. It is introduced here in a broader sense to cover all existence dependent, but semantically described, modifiers of an element’s shape and appearance. It is envisioned that future releases enhance the feature-based capabilities of the IFC model.

In contrary to the aggregation, as used in IfcElementAssembly, that defines the aggregate as a container element, that has equally treated parts, the feature concept introduced by IfcFeatureElement defines the master element with subordinate parts as additions, or with voids or cut-outs as subtractions.

HISTORY New entity in Release IFC2x Edition 2. NOTE The entity is introduced as an upward compatible extension of the IFC2x platform. It is an intermediate abstract supertype without defining its own explicit attributes.

Containment Use Definition As a subordinate part being fully dependent on the master element the IfcFeatureElement shall have no independent containment relationship to the spatial structure.

The SELF\IfcElement.ContainedInStructure relationship shall be NIL.

Geometry Use Definition The geometric representation of IfcFeatureElement is given by the IfcProductDefinitionShape, allowing multiple geometric representation. Local Placement The local placement for IfcFeatureElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the master IfcElement (its relevant subtypes), which is associated to the IfcFeatureElement by the appropriate relationship object. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations Any IfcFeatureElement can be represented by one or several geometric representations. A detailed specification is introduced at the level of subtypes. Only the general representation identifier ‘Box’ with representation type ‘BoundingBox’, and representation identifier ‘Body’ with representation type ‘Brep’ are defined here. Box Representation Any IfcFeatureElement may be represented as a bounding box, which shows the maximum extend of the body within the coordinated system established by the IfcLocalPlacement. The bounding box representation is the simplest geometric representation available. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Box’ RepresentationType : ‘BoundingBox’

Body Representation The body representation of any IfcFeatureElement can have the following representation types: ‘Brep’. Other representation types might be specified at the level of subtypes. Brep Representation Type Any IfcFeatureElement (so far no further constraints are defined at the level of its subtypes) may be represented as a single or multiple Boundary Representation elements (which are restricted to faceted Brep with or without voids). The Brep representation allows for the representation of complex element shape. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Body’ RepresentationType : ‘Brep’

In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape.

class IfcFillAreaStyle : public Ifc2x3::IfcPresentationStyle

Definition from ISO/CD 10303-46:1992: The style for filling visible curve segments, annotation fill areas or surfaces with tiles or hatches.

An IfcFillAreaStyle provides the style table for presentation information assigned to annotation fill areas or surfaces for hatching and tiling. The IfcFillAreaStyle defines hatches as model hatches, that is, the distance between hatch lines, or the curve patterns of hatch lines are given in model space dimensions (that have to be scaled using the target plot scale). The IfcFillAreaStyle allows for the following combinations of defining the style of hatching and tiling:

Solid fill for areas and surfaces by only assigning IfcColour to the set of FillStyles. It then provides the background colour for the filled area or surface.

NOTE Color information of surfaces for rendering is assigned by using IfcSurfaceStyle, not by using IfcFillAreaStyle.

Vector based hatching for areas and surfaces based on a single row of hatch lines by assigning a single instance of IfcFillAreaStyleHatching to the set of FillStyles. If an instance of IfcColour is assigned in addition to the set of FillStyles, it provides the background colour for the hatching. Vector based hatching for areas and surfaces based on two (potentially crossing) rows of hatch lines by assigning two instances of IfcFillAreaStyleHatching to the set of FillStyles.

If an instance of IfcColour is assigned in addition to the set of FillStyles, it provides the background colour for the hatching.

NOTE Assigning more then two instances of IfcFillAreaStyleHatching to define three or more rows of hatch lines is not encouraged.

Tiling for areas and surfaces by assigning a single instance of IfcFillAreaStyleTiles to the set of FillStyles. If an instance of IfcColour is assigned in addition to the set of FillStyles, it provides the background colour for the tiling.

IFC2x3 NOTE The use of IfcFillAreaStyleTiles is discouraged., as its definition might change is future releases.

Externally defined hatch style by assigning a single instance of IfcExternallyDefinedHatchStyle to the set of FillStyles. If an instance of IfcColour is assigned in addition to the set of FillStyles, it provides the background colour for the hatching.

Measures given to a hatch or tile pattern are given in global drawing length units.

NOTE Global units are defined at the single IfcProject instance, given by UnitsInContext:IfcUnitAssignment, the same units are used for the geometric representation items and for the style definitions.

The measure values for hatch or tile pattern apply to the model space with a target plot scale provided for the correct appearance in the default plot scale. For different scale and projection dependent fill area styles a different instance of IfcFillAreaStyle needs to be used by IfcPresentationStyleAssignment for different IfcGeometricRepresentationSubContext dependent representations.

NOTE the target plot scale is given by IfcGeometricRepresentationSubContext.TargetScale.

An IfcFillAreaStyle can be assigned to IfcFillArea via the IfcPresentationStyleAssignment through an intermediate IfcStyledItem or subtype IfcAnnotationFillAreaOccurrence.

class IfcFillAreaStyleHatching : public Ifc2x3::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-46:1992: The fill area style hatching defines a styled pattern of curves for hatching an annotation fill area or a surface.

The IfcFillAreaStyleHatching is used to define simple, vector-based hatching patterns, based on styled straight lines. The curve font, color and thickness is given by the HatchLineAppearance, the angle by the HatchLineAngle and the distance to the next hatch line by StartOfNextHatchLine, being either an offset distance or a vector.

NOTE If the hatch pattern involves two (potentially crossing) rows of hatch lines, then two instances of IfcFillAreaStyleHatching should be assigned to the IfcFillAreaStyle. Both share the same (virtual) point of origin of the hatching that is used by the reference hatch line (or the PointOfReferenceHatchLine if there is an offset).

For better control of the hatching appearance, when using hatch lines with other fonts then continuous, the PatternStart allows to offset the start of the curve font pattern along the reference hatch line (if not given, the PatternStart is at zero distance from the virtual point of origin). If the reference hatch line does not go through the origin (of the virtual hatching coordinate system), it can be offset by using thePatternStartPointOfReferenceHatchLine.

NOTE The coordinates of the PatternStart and the PointOfReferenceHatchLine are given relative to the assumed 0., 0. virtual point of origin at which the hatch pattern is later positioned by the FillStyleTarget point at IfcAnnotationFillAreaOccurrence. The measure values are given in global drawing length units and apply to the target plot scale for the scale depended representation subcontext.

NOTE The use of PointOfReferenceHatchLine is deprecated.

Figure 292 illustrates hatch attributes.

Example 1 This example shows simple hatching given by using a curve font “continuous” at HatchLineAppearance.

The distance of hatch lines is given by a positive length measure. The angle (here 45’ if measures in degree) is provided by HatchLineAngle.

The PatternStart is set to NIL ($) in this example. Example 2 This shows hatching from example 1 with using a different curve font at HatchLineAppearance. The distance of hatch lines is given by a positive length measure, therefore the font pattern start is at a point at the next hatch line given by a vector being perpendicular to the point of origin at the reference hatch line. The PatternStart is set to NIL ($) in this example. Example 3 This example uses hatching from example 2 with a vector to determine the pattern start of the next hatch lines. The pattern start is the beginning of the first visual curve font pattern segment at IfcCurveFont.CurveFont. The PatternStart is set to NIL ($) in this example. Example 4 This example uses hatching from example 3 where the pattern start is offset from the point of origin at the reference hatch line. That is, the first visible curve font pattern segment now does not start at the point of origin at the reference hatch line.

Example 5 This example uses hatching from example 4 where the hatch pattern is shifted against the underlying coordinate system. The point that is mapped to the insertion point of the IfcAnnotationFillAreaOccurrence now has an X and Y offset from the start of the reference hatch line. That is, the reference hatch line now does not go through the insertion point of the hatching.

Example 6 This example shows use of

IfcFillAreaStyleHatching attributes for two IfcFillAreaStyleHatching’s within one IfcFillAreaStyle. Note that the PatternStart now displaces both the reference hatch line from the point of origin and the start of the curve pattern. This can be used in cases when more than one IfcFillAreaStyleHatching is used in an IfcFillAreaStyle in order to place rows of hatch lines with an offset from each other.

HISTORY: New entity in IFC R2.0. IFC 2x4 NOTE: This entity has been deprecated for instantiation and will become ABSTRACT in a future release; new subtypes should now be used instead.

The IfcFlowSegment defines a particular occurrence of a segment inserted in the spatial context of a project. The parameters defining the type of the segment and/or its shape are defined by the IfcFlowSegmentType, which is related by the inverse relationship IsDefinedBy pointing to IfcRelDefinesByType.

Material Use Definition The material of the IfcFlowSegment is defined using one of the following entities:

IfcMaterialProfileSetUsage : for parametric segments, this defines the cross section and alignment to the ‘Axis’ representation, from which the ‘Body’ representation may be generated.

IfcMaterialProfileSet : for non-parametric segments (having fixed length or path), this may define the cross section for analysis purposes, however the ‘Body’ representation is independently generated.

IfcMaterialConstituentSet : for elements containing multiple materials where profiles are not applicable, this indicates materials at named parts.

IfcMaterial : for elements comprised of a single material where profiles are not applicable, this indicates the material.

The material is attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcFlowSegmentType, defining the common attribute data for all occurrences of the same type. Standard names and material types are defined at subtypes.

Representation Use Definition

Standard representations are defined at the supertype IfcDistrubutionFlowElement. For parametric flow segments where IfcMaterialProfileSetUsage is defined and an ‘Axis’ representation is defined, then the ‘Body’ representation may be generated using the ‘SweptSolid’ or ‘AdvancedSweptSolid’ representation types by sweeping the profile(s) along the axis.

class IfcFontStyle : public IfcUtil::IfcBaseType

Definition from CSS1 (W3C Recommendation): The font-style property selects between normal (sometimes referred to as “roman” or “upright”), italic and oblique faces within a font family. Values are:

normal italic oblique

A value of ‘normal’ selects a font that is classified as ‘normal’ in the user agents font database, while ‘oblique’ selects a font that is labeled ‘oblique’. A value of ‘italic’ selects a font that is labeled ‘italic’, or, if that is not available, one labeled ‘oblique’. The font that is labeled ‘oblique’ in the user agents font database may actually have been generated by electronically slanting a normal font.

Fonts with Oblique, Slanted or Incline in their names will typically be labeled ‘oblique’ in the user agents font database. Fonts with Italic, Cursive or Kursiv in their names will typically be labeled ‘italic’.

Definition from CSS1 (W3C Recommendation): The font-style property selects between normal and small-caps within a font family. Values are:

Another type of variation within a font family is the small-caps. In a small-caps font the lower case letters look similar to the uppercase ones, but in a smaller size and with slightly different proportions. The ‘font-variant’ property selects that font.

A value of ‘normal’ selects a font that is not a small-caps font, ‘small-caps’ selects a small-caps font. It is acceptable (but not required) in CSS1 if the small-caps font is a created by taking a normal font and replacing the lower case letters by scaled uppercase characters. As a last resort, uppercase letters will be used as replacement for a small-caps font.

class IfcFontWeight : public IfcUtil::IfcBaseType

Definition from CSS1 (W3C Recommendation): The ‘font-weight’ property selects the weight of the font. The values ‘100’ to ‘900’ form an ordered sequence, where each number indicates a weight that is at least as dark as its predecessor. The keyword ‘normal’ is synonymous with ‘400’, and ‘bold’ is synonymous with ‘700’. Keywords other than ‘normal’ and ‘bold’ have been shown to be often confused with font names and a numerical scale was therefore chosen for the 9-value list. Values are:

normal bold 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900

Fonts (the font data) typically have one or more properties whose values are names that are descriptive of the “weight” of a font. There is no accepted, universal meaning to these weight names. Their primary role is to distinguish faces of differing darkness within a single font family. Usage across font families is quite variant; for example a font that you might think of as being bold might be described as being Regular, Roman, Book, Medium, Semi- or DemiBold, Bold, or Black, depending on how black the “normal” face of the font is within the design. Because there is no standard usage of names, the weight property values in CSS1 are given on a numerical scale in which the value ‘400’ (or ‘normal’) corresponds to the “normal” text face for that family. The weight name associated with that face will typically be Book, Regular, Roman, Normal or sometimes Medium.

The association of other weights within a family to the numerical weight values is intended only to preserve the ordering of darkness within that family. However, the following heuristics tell how the assignment is done in typical cases:

If the font family already uses a numerical scale with nine values (such as with OpenType), the font weights should be mapped directly. If there is both a face labeled Medium and one labeled Book, Regular, Roman or Normal, then the Medium is normally assigned to the ‘500’. The font labeled “Bold” will often correspond to the weight value ‘700’. If there are fewer then 9 weights in the family, the default algorithm for filling the “holes” is as follows. If ‘500’ is unassigned, it will be assigned the same font as ‘400’. If any of the values ‘600’, ‘700’, ‘800’ or ‘900’ remains unassigned, they are assigned to the same face as the next darker assigned keyword, if any, or the next lighter one otherwise. If any of ‘300’, ‘200’ or ‘100’ remains unassigned, it is assigned to the next lighter assigned keyword, if any, or the next darker otherwise.

The following two examples illustrate the process. Assume four weights in the “Example1” family, from lightest to darkest: Regular, Medium, Bold, Heavy. And assume six weights in the “Example2” family: Book, Medium, Bold, Heavy, Black, ExtraBlack. Note how in the second example it has been decided not to assign “Example2 ExtraBlack” to anything.

Available faces | Assignments | Filling the holes——————-+————+—————-“Example1 Regular” | 400 | 100, 200, 300”Example1 Medium” | 500 |”Example1 Bold” | 700 | 600”Example1 Heavy” | 800 | 900 Available faces | Assignments | Filling the holes——————-+————+—————-“Example2 Book” | 400 | 100, 200, 300”Example2 Medium” | 500 |”Example2 Bold” | 700 | 600 “Example2 Heavy” | 800 |”Example2 Black” | 900 |”Example2 ExtraBlack” | (none) |

NOTE Corresponding CSS1 definitions is font-weight.

class IfcFurnishingElement : public Ifc2x3::IfcElement

Definition from IAI: Generalization of all furniture related objects. Furnishing objects are characterized as being

pre-manufactured and assembled on-site, or manufactured on-site (built-in)

Thus furnishing elements can either be movable, or not (as the built-ins). HISTORY New entity in IFC Release 2x. IFC2x4 CHANGE The entity is marked as deprecated for instantiation - will be made ABSTRACT after IFC2x4. Geometry Use Definitions: The geometric representation of IfcFurnishingElement is given by the IfcProductDefinitionShape and IfcLocalPlacement allowing multiple geometric representation. Local Placement The local placement for IfcFurnishingElement is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement , which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations Any IfcFurnishingElement can be represented by one or several geometric representations. This includes the general representation types ‘BoundingBox’, ‘GeometricCurveSet’, ‘SurfaceModel’, ‘Brep’, and ‘MappedRepresentation’ being defined here. Bounding Box Representation Any IfcFurnishingElement may be represented as a bounding box, which shows the maximum extend of the body within the coordinated system established by the IfcLocalPlacement. The bounding box representation is the simplest geometric representation available. The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

RepresentationIdentifier : ‘Box’ RepresentationType : ‘BoundingBox’

Foot Print Representation The foot print representation of IfcFurnishingElement is given by either a single or multiple 2D points and curves. The representation identifier and type of this geometric representation are:

IfcShapeRepresentation.RepresentationIdentifier = ‘FootPrint’ IfcShapeRepresentation.RepresentationType = ‘GeometricCurveSet’

SurfaceModel Representation Any IfcFurnishingElement (so far no further constraints are defined at the level of its subtypes) may be represented as a single or multiple surface models, based on either shell or face based models. In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape. The representation identifier and type of this geometric representation are:

IfcShapeRepresentation.RepresentationIdentifier = ‘Body’ IfcShapeRepresentation.RepresentationType = ‘SurfaceModel’

Brep Representation Any IfcFurnishingElement (so far no further constraints are defined at the level of its subtypes) may be represented as a single or multiple Boundary Representation elements (which are restricted to faceted Brep with or without voids). The Brep representation allows for the representation of complex element shape. In some cases it may be useful to also expose a simple representation as a bounding box representation of the same complex shape. The representation identifier and type of this geometric representation are:

IfcShapeRepresentation.RepresentationIdentifier = ‘Body’ IfcShapeRepresentation.RepresentationType = ‘Brep’

MappedRepresentation The IfcMappedItem should always be used in appropriate cases as it allows for reusing the geometry definition of the furnishing type for all occurrences of the same type. The representation identifier and type of this geometric representation are:

IfcShapeRepresentation.RepresentationIdentifier = ‘FootPrint’, or ‘Body’ (depending of the representation map) IfcShapeRepresentation.RepresentationType = ‘MappedRepresentation’

Definition from IAI: The IfcFurnishingElementType defines a list of commonly shared property set definitions of an element and an optional set of product representations. It is used to define an element specification (i.e. the specific product information, that is common to all occurrences of that product type). NOTE The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem. A furnishing element type is used to define the common properties of a certain type of a furnishing element that may be applied to many instances of that feature type to assign a specific style. Furnishing element types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences. The occurrences of the IfcFurnishingElementType are represented by instances of IfcFurnishingElement (or its subtypes). HISTORYNew entity in Release IFC2x Edition 2. IFC2x3 CHANGE The entity has been made non-abstract IFC2x4 CHANGE The entity is marked as deprecated for instantiation - will be made ABSTRACT after IFC2x4.

class IfcGeometricRepresentationContext : public Ifc2x3::IfcRepresentationContext

Definition from ISO/CD 10303-42:1992: A geometric representation context is a representation context in which the geometric representation items are geometrically founded. A geometric representation context is a distinct coordinate space, spatially unrelated to other coordinate spaces.

IfcGeometricRepresentationContext defines the context that applies to several shape representations of products within a project. It defines the type of the context in which the shape representation is defined, and the numeric precision applicable to the geometric representation items defined in this context. In addition it can be used to offset the project coordinate system from a global point of origin, using the WorldCoordinateSystem attribute.

As shown in Figure 329, the TrueNorth attribute should be provided if the y axis of the WorldCoordinateSystem does not point to the global northing. Direction of the true north, or geographic northing direction, relative to the underlying project coordinate system as established by the attribute WorldCoordinateSystem. It is given by a 2 dimensional direction within the xy-plane of the project coordinate system. If not resent, it defaults to [0.,1.] - i.e. the positive Y axis of the project coordinate system equals the geographic northing direction. The direction is provided within project coordinate system and identifies the true north direction (see figure).

Figure 329 — Geometric representation context true north

NOTEThe inherited attribute ContextType shall have one of the following recognized values: ‘Sketch’, ‘Outline’, ‘Design’, ‘Detail’, ‘Model’, ‘Plan’, ‘NotDefined’.

The use of one instance of IfcGeometricRepresentationContext to represent the model (3D) view is mandatory, the use of a second instance of IfcGeometricRepresentationContext to represent the plan (2D) view is optional (but needs to be given, if there are scale dependent plan views), the additional scale or view dependent contexts need to be handled by using the subtype IfcGeometricRepresentationSubContext pointing to the model view (or the plan view) as the ParentContext.

Figure 330 illustrates use of representation contexts defined at IfcProject for 3D model and 2D plan context, including sub context definitions for different target scales.

class IfcGeometricRepresentationItem : public Ifc2x3::IfcRepresentationItem

Definition from ISO/CD 10303-43:1992: An geometric representation item is a representation item that has the additional meaning of having geometric position or orientation or both. This meaning is present by virtue of:

being a Cartesian point or a direction

referencing directly a Cartesian point or direction

referencing indirectly a Cartesian point or direction

An indirect reference to a Cartesian point or direction means that a given geometric item references the Cartesian point or direction through one or more intervening geometry or topology items.

EXAMPLE: Consider a circle. It gains its geometric position and orientation by virtue of a reference to axis2_placement (IfcAxis2Placement) that is turn references a cartesian_point (IfcCartesianPoint) and several directions (IfcDirection).

EXAMPLE: Consider a manifold brep. A manifold_solid_brep (IfcManifoldSolidBrep) is a geometric_representation_item (IfcGeometricRepresentationItem) that through several layers of topological_representation_item’s (IfcTopologicalRepresentationItem) references poly loops (IfcPolyLoop). Through additional intervening entities poly loops reference cartesian_point’s (IfcCartesianPoint).

The derivation of the dimensionality of the IfcGeometricRepresentationItem is different to ISO 10303; there is a specific derived attribute at each class that defines the dimensionality, whereas ISO 10303 does it for the representation_context and requires all geometric_representation_item’s to have the same dimensionality therein.

The definition of swept area solids as geometric representation items is different to ISO 10303; it is based on a set of predefined profiles (or cross sections), that is, a set of parameterized geometric primitives widely supported in the industry. Those profiles are used to create volumes through extrusion, revolution and cross section based sweep operations.

NOTE: Corresponding ISO 10303 entity: geometric_representation_item. Please refer to ISO/IS 10303-42:1994, p. 22 for the final definition of the formal standard. The following changes have been made: It does not inherit from ISO/IS 10303-43:1994 entity representation_item. The derived attribute Dim is demoted to the appropriate subtypes. The WR1 has not been incorporated. Not all subtypes that are in ISO/IS 10303-42:1994 have been added to the current IFC Release.

class IfcGeometricRepresentationSubContext : public Ifc2x3::IfcGeometricRepresentationContext

IfcGeometricRepresentationSubContext defines the context that applies to several shape representations of a product being a sub context, sharing the WorldCoordinateSystem, CoordinateSpaceDimension, Precision and TrueNorth attributes with the parent IfcGeometricRepresentationContext.

The IfcGeometricRepresentationSubContext is used to define semantically distinguished representation types for different information content, dependent on the representation view and the target scale. It can be used to control the level of detail of the shape representation that is most applicable to this geometric representation context. addition the sub context is used to control the later appearance of the IfcShapeRepresentation within a plot view.

NOTE If the IfcShapeRepresentation using this sub context has IfcStyledItem’s assigned to the Items, the presentation style information (e.g. IfcCurveStyle, IfcTextStyle) associated with the IfcStyledItem is given in target plot dimensions. For example, a line thickness (IfcCurveStyle.CurveWidth) is given by a thickness measure relating to the thickness for a plot within the (range of) target scale.

Each IfcProduct can then have several instances of subtypes of IfcRepresentation, each being assigned to a different geometric representation context (IfcGeometricRepresentationContext or IfcGeometricRepresentationSubContext). The application can then choose the most appropriate representation for showing the geometric shape of the product, depending on the target view and scale.

NOTE The provision of a model view (IfcGeometricRepresentationContext.ContextType = ‘Model’) is mandatory. Instances of IfcGeometricRepresentationSubContext relate to it as its ParentContext.

EXAMPLE Instances of IfcGeometricRepresentationSubContext can be used to handle the multi-view blocks or macros, which are used in CAD programs to store several scale and/or view dependent geometric representations of the same object.

class IfcGrid : public Ifc2x3::IfcProduct

IfcGrid ia a planar design grid defined in 3D space used as an aid in locating structural and design elements. The position of the grid (ObjectPlacement) is defined by a 3D coordinate system (and thereby the design grid can be used in plan, section or in any position relative to the world coordinate system). The position can be relative to the object placement of other products or grids. The XY plane of the 3D coordinate system is used to place the grid axes, which are 2D curves (for example, line, circle, trimmed curve, polyline, or composite curve). The inherited attributes Name and Description can be used to define a descriptive name of the grid and to indicate the grid’s purpose.A grid is defined by (normally) two, or (in case of a triangular grid) three lists of grid axes. The following table shows some examples. A grid may support a rectangular layout (Figure 28), a radial layout (Figure 29), or a triangular layout (Figure 30).

Figure 28 — Grid rectangular layout Figure 29 — Grid radial layout Figure 30 — Grid triangular layout

The grid axes, defined within the design grid, are those elements to which project objects will be placed relatively using the IfcGridPlacement.

HISTORY New entity in IFC Release 1.0. Informal Proposition

Grid axes, which are referenced in different lists of axes (UAxes, VAxes, WAxes) shall not be parallel. Grid axes should be defined such as there are no two grid axes which intersect twice (see Figure 31).

left side: ambiguous intersections A1 and A2, a grid containing such grid axes is not a valid design grid. right side: the conflict can be resolved by splitting one grid axis in a way, such as no ambiguous intersections exist.

Figure 31 — Grid intersections

Geometry Use Definitions The geometric representation of IfcGrid is given by the IfcProductDefinitionShape, allowing geometric representations. Included are: Local Placement The local placement for IfcGrid is defined in its supertype IfcProduct. It is defined by the IfcLocalPlacement, which defines the local coordinate system that is referenced by all geometric representations.

The PlacementRelTo relationship of IfcLocalPlacement shall point (if given) to the local placement of the same IfcSpatialStructureElement, which is used in the ContainedInStructure inverse attribute, or to a spatial structure element at a higher level, referenced by that. If the relative placement is not used, the absolute placement is defined within the world coordinate system.

Geometric Representations Currently, the use of a 2D ‘FootPrint’ representation of type ‘GeometricCurveSet’ is supported. GeometricCurveSet representation The 2D geometric representation of IfcGrid is defined using the ‘GeometricCurveSet’ geometry. The following attribute values should be inserted

IfcShapeRepresentation.RepresentationIdentifier = ‘FootPrint’. IfcShapeRepresentation.RepresentationType = ‘GeometricCurveSet’ .

The following constraints apply to the 2D representation:

The IfcGeometricCurveSet shall be an (and the only) Item of the IfcShapeRepresentation. It should contain an IfcGeometricCurveSet containing subtypes of IfcCurve, each representing a grid axis. Applicable subtypes of IfcCurve are: IfcPolyline, IfcCircle, IfcTrimmedCurve (based on BaseCurve referencing IfcLine or IfcCircle). Each subtype of IfcCurve may have a curve style assigned, using IfcAnnotationCurveOccurrence referencing IfcCurveStyle. Optionally the grid axis labels may be added as IfcTextLiteral, and they may have text styles assigned, using IfcAnnotationTextOccurrence referencing IfcTextStyle.

As shown in Figure 32, the IfcGrid defines a placement coordinate system using the ObjectPlacement. The XY plane of the coordinate system is used to place the 2D grid axes. The Representation of IfcGrid is defined using IfcProductRepresentation, referencing an IfcShapeRepresentation, that includesIfcGeometricCurveSet as Items. All grid axes are added as IfcPolyline to the IfcGeometricCurveSet.

Figure 32 — Grid layout

As shown in Figure 33, the attributes UAxes and VAxes define lists of IfcGridAxis within the context of thegrid. Each instance of IfcGridAxis refers to the same instance of IfcCurve (here the subtype IfcPolyline) that is contained within the IfcGeometricCurveSet that represents the IfcGrid.

class IfcGridAxis : public IfcUtil::IfcBaseEntity

An individual axis, IfcGridAxis, is defined in the context of a design grid. The axis definition is based on a curve of dimensionality 2. The grid axis is positioned within the XY plane of the position coordinate system defined by the IfcDesignGrid.

HISTORY New entity in IFC Release 1.0

Geometry use definitions The standard geometric representation of IfcGridAxis is defined using a 2D curve entity. Grid axes are normally defined by an offset to another axis. The IfcOffsetCurve2D supports this concept. Each grid axis has a sense given by the parameterization of the curve. The attribute SameSense is an indicator of whether or not the sense of the grid axis agrees with, or opposes, that of the underlying curve. As shown in Figure 242, the grid axis is defined as a 2D curve within the xy plane of the position coordinate system. Any curve can be used to define a grid axis, most common is the use of IfcLine for linear grids and IfcCircle for radial grids. Most grids are defined by a pair of axis lists, each defined by a base grid axis and axes given by an offset to the base axis. The use of IfcOffsetCurve2D as underlying AxisCurve supports this concept.

class IfcGridPlacement : public Ifc2x3::IfcObjectPlacement

IfcGridPlacement provides a specialization of IfcObjectPlacement in which the placement and axis direction of the object coordinate system is defined by a reference to the design grid as defined in IfcGrid. The location of the object coordinate system is given by the attribute PlacementLocation. It is defined as an IfcVirtualGridIntersection, that is, an intersection between two grid axes with optional offsets. The axis direction of the x-axis of the object coordinate system is given either:

PlacementRefDirection = NIL: by the tangent of the first grid axis (PlacementLocation.IntersectingAxes[1]) at the virtual intersection (maybe using the offset curve, if PlacementLocation.OffsetDistances is given); PlacementRefDirection = IfcDirection: by the explicitly provided direction information; PlacementRefDirection = IfcVirtualGridIntersection: by the tangent between the virtual grid intersection of PlacementLocation and the virtual grid intersection of PlacementRefDirection. Offsets as potentially provided in the IfcVirtualGridIntersection’s of PlacementLocation and PlacementRefDirection have to be taken into account.

The direction of the y-axis of the IfcGridPlacement is the orthogonal complement to the x-axis. The plane defined by the x and y axis shall be co-planar to the xy plane of the local placement of the IfcGrid. The direction of the z-axis is the orientation of the cross product of the x-axis and the y-axis, i.e. the z-axis of the IfcGridPlacement shall be co-linear to the z-axis of the local placement of the IfcGrid.

NOTE The IfcGrid local placement, that can be provided relative to the local placement of another spatial structure element, has to be taken into account for calculating the absolute placement of the virtual grid intersection.

NOTE The PlacementLocation.OffsetDistances[3] and the PlacementRefDirection.OffsetDistances[3] shall either not be assigned or should have the same z offset value.

HISTORY New entity in IFC Release 1.5. The entity name was changed from IfcConstrainedPlacement in IFC Release 2x.

IFC2x4 CHANGE Attribute data type of PlacementRefDirection has been changed to IfcGridPlacementDirectionSelect.

Geometry use definitions The following examples show the usage of placement location and direction for an IfcGridPlacement.

Figure 243 illustrates the case where PlacementRefDirection is not given - the object coordinate system is defined by:

its location: given by the virtual grid intersection of PlacementLocation its x-axis direction: given by the tangent of the first intersecting axis in the offset location of the virtual grid intersection

Figure 243 — Grid placement

Figure 244 illustrates the case where PlacementRefDirection is given as an IfcDirection- the object coordinate system is defined by:

class IfcGroup : public Ifc2x3::IfcObject

IfcGroup is an generalization of any arbitrary group. A group is a logical collection of objects. It does not have its own position, nor can it hold its own shape representation. Therefore a group is an aggregation under some non-geometrical / topological grouping aspects.

NOTE Use IfcRelDecomposes together with the appropriate subtypes of IfcProduct to define an aggregation of products that may have its own position and shape representation.

EXAMPLE An example for a group is a system, since it groups elements under the aspect of their role, regardless of their position in a building.

A group can hold any collection of objects (beingproducts, processes, controls, resources, actors or other groups). Thus groups can be nested. An object can be part of zero, one, or many groups. Grouping relationships are not required to be hierarchical nor do they imply a dependency.

NOTE Use IfcRelDecomposes together with the appropriate subtypes of IfcProduct to define an hierarchical aggregation of products.

A group can be exchanged without having already objects within the group collection.

HISTORY New entity in IFC Release 1.0.

IFC2x4 CHANGE The inverse IsGroupedBy relationship is set to 0..n

Relationship use definition The group collection is handled by an instance of IfcRelAssignsToGroup, which assigns all group members to the IfcGroup.

Objects: included in group using IfcRelAssignsToGroup

Groups are assigned to other objects (such as a process or a resource) by the relationship object that refers to the corresponding object:

Process: assigned using IfcRelAssignsToProcess Resource: assigned using IfcRelAssignsToResource

Groups can be subjected to a control. The control information is then assigned:

class IfcHalfSpaceSolid : public Ifc2x3::IfcGeometricRepresentationItem

Definition from ISO/CD 10303-42:1992: A half space solid is defined by the half space which is the regular subset of the domain which lies on one side of an unbounded surface. The side of the surface which is in the half space is determined by the surface normal and the agreement flag. If the agreement flag is TRUE, then the subset is the one the normal points away from. If the agreement flag is FALSE, then the subset is the one the normal points into. For a valid half space solid the surface shall divide the domain into exactly two subsets. Also, within the domain the surface shall be manifold and all surface normals shall point into the same subset.

NOTE A half space is not a subtype of solid model (IfcSolidModel), half space solids are only useful as operands in Boolean expressions.

NOTE Corresponding STEP entity: half_space_solid. Please refer to ISO/IS 10303-42:1994, p. 185 for the final definition of the formal standard. The derived attribute Dim has been added at this level and was therefore demoted from the geometric_representation_item.

HISTORY New class in IFC Release 1.5

Informal propositions:

The base surface shall divide the domain into exactly two subsets. If the half space solid is of subtype boxed half space (IfcBoxedHalfSpace), the domain in question is that of the attribute enclosure. In all other cases the domain is all of space and the base surface shall be unbounded. The base surface shall be an unbounded surface (subtype of IfcElementarySurface).

Figure 258 illustrates the definition of the IfcHalfSpaceSolid within a given coordinate system. The base surface is given by an unbounded plane, the red boundary is shown for visualization purposes only.

Definition from ISO/CD 10303-41:1992: An identifier is an alphanumeric string which allows an individual thing to be identified. It may not provide natural-language meaning.

Type: STRING of up to 255 characters

NOTE Corresponding STEP name: identifier, please refer to ISO/IS 10303-41 for the final definition of the formal standard.

HISTORY New type in IFC Release 2x. IFC 2x4 CHANGE: Previously recommended size restriction of 255 characters is now mandatory.

As a merely machine-readable string for identification purposes, an identifier is usually machine-generated and locale-independent (in contrast to human-readable labels, IfcLabel).

Per ISO 10303-11, the set of characters that may appear in STRINGs is defined in ISO 10646. The encoding of characters in case of file-based exchange is defined in ISO 10303-21 (STEP physical files) and ISO 10303-28 (XML files). Among else, these specifications define the encoding of 8-bit characters from ISO 8859-1…-16 and of 2-byte Unicode characters.

Note that while IfcIdentifier is restricted to 255 characters, the size in exchange files after encoding may be considerably larger than 255 octets, depending on the particular encoding and on the contents of the identifier.

class IfcImageTexture : public Ifc2x3::IfcSurfaceTexture

An IfcImageTexture provides a 2-dimensional texture that can be applied to a surface of an geometric item and that provides lighting parameters of a surface onto which it is mapped. The texture is provided as an image file at an external location for which an URL is provided.

The following definitions from ISO/IEC 19775-1 X3D Architecture and base components (X3D Specification) apply:

The ImageTexture node defines a texture map by specifying an image file and general parameters for mapping to geometry. The texture is read from the URL specified by the url field. When the url field contains no [resolvable] values, texturing is disabled. Browsers shall support the JPEG and PNG (see ISO/IEC 15948) image file formats. Texture nodes that require support for the PNG image format shall interpret the PNG pixel formats in the following way:

Greyscale pixels without alpha or simple transparency are treated as intensity textures. >Greyscale pixels with alpha or simple transparency are treated as intensity plus alpha textures. RGB pixels without alpha channel or simple transparency are treated as full RGB textures. RGB pixels with alpha channel or simple transparency are treated as full RGB plus alpha textures.

If the image specifies colours as indexed-colour (that is, palettes or colourmaps), the following semantics should be used (note that greyscale refers to a palette entry with equal red, green, and blue values):

If all the colours in the palette are greyscale and there is no transparency chunk, it is treated as an intensity texture. If all the colours in the palette are greyscale and there is a transparency chunk, it is treated as an intensity plus opacity texture. >If any colour in the palette is not grey and there is no transparency chunk, it is treated as a full RGB texture. If any colour in the palette is not grey and there is a transparency chunk, it is treated as a full RGB plus alpha texture.

Texture nodes that require support for JPEG files shall interpret JPEG files as follows:

Greyscale files (number of components equals 1) are treated as intensity textures. YCbCr files are treated as full RGB textures. No other JPEG file types are required. It is recommended that other JPEG files are treated as a full RGB textures.

Texture nodes that recommend support for GIF files shall follow the applicable semantics described above for the PNG format.

The Uniform Resource Locator (URL) is a form of an URI and specified in RFC1738 by IETF. It supports resources located on a particular server being accessed by a particular protocol (usually http), and resources located at a local machine.

NOTE Exchange files following the ifcZIP convention may include a sub directory structure for image resources to be stored together with the product data set.

NOTE The definitions of texturing within this standard have been developed in dependence on the texture component of X3D. See ISO/IEC 19775-1.2:2008 X3D Architecture and base components Edition 2, Part 1, 18 Texturing component for the definitions in the international standard.

class IfcInventory : public Ifc2x3::IfcGroup

An inventory is a list of items within an enterprise.

Various types of inventory can be included. These are identified by the range of values within the inventory type enumeration which includes space, asset, and furniture. User defined inventories can also be defined for lists of particular types of element such as may be required in operating and maintenance instructions. Such inventories should be constrained to contain a list of elements of a restricted type.There are a number of actors that can be associated with an inventory, each actor having a role. Actors within the scope of the project are indicated using the IfcRelAssignsToActor relationship in which case roles should be defined through the IfcActorRole class; otherwise principal actors are identified as attributes of the class. In the existence of both, direct attributes take precedence.There are a number of costs that can be associated with an inventory, each cost having a role. These are specified through the CurrentValue and OriginalValue attributes.HISTORY: New entity in IFC2.0. Modified in IFC2x4 to make all attributes optional and remove Where Rule.

Assignment Use Definition The IfcInventory may have assignments of its own using the IfcRelAssignsToGroup relationship where RelatingGroup refers to the IfcInventory and RelatedObjects contains one or more objects of the following types: IfcAsset: Assets included in the inventory.

IfcElement: Elements such as furniture included in the inventory.

class IfcIShapeProfileDef : public Ifc2x3::IfcParameterizedProfileDef

IfcIShapeProfileDef defines a section profile that provides the defining parameters of a symmetrical ‘I’ section to be used by the swept surface geometry or the swept area solid. The I-shape profile has values for its overall depth, width and its web and flange thickness. Additionally a fillet radius may be given. It represents a I-section that is symmetrical about its major and minor axes; and that has both top and bottom flanges being equal and centred on the web.

IfcIShapeProfileDef can also be used to model I sections with sloped or rounded flanges. The slope and radius cannot be expressed in explicit attributes, but they may be retrieved by reference to an external document or library. See IfcProfileDef for guidance on external references for profile definitions.

HISTORY New entity in IFC2x.

IFC2x4 CHANGE Type of FilletRadius relaxed to allow for zero radius.

Figure 318 illustrates parameters of the I-shape profile definition.

Position

The parameterized profile defines its own position coordinate system. The underlying coordinate system is defined by the swept area solid that uses the profile definition. It is the xy plane of:

IfcSweptAreaSolid.Position

by using offsets of the position location, the parameterized profile can be positioned centric (using x,y offsets = 0.), or at any position relative to the profile. Explicit coordinate offsets are used to define cardinal points (e.g. upper-left bound). Parameter

The parameterized profile is defined by a set of parameter attributes, see attribute definition below.

Note: The black coordinate axes show the underlying coordinate system of the swept surface or swept area solid

Position

The profile is inserted into the underlying coordinate system of the swept area solid by using the Position attribute. In this example (cardinal point of lower left corner) the attribute values of IfcAxis2Placement2D are:

Location = IfcCartesianPoint(,) RefDirection = NIL (defaults to 1.,0.)

Parameter If the FilletRadius is given, it is equally applied to all four corners created by the web and flanges.

Type: STRING of up to 255 characters

NOTE Corresponding STEP name: label, please refer to ISO/IS 10303-41 for the final definition of the formal standard.

HISTORY New type in IFC Release 2x. IFC 2x4 CHANGE: Previously recommended size restriction of 255 characters is now mandatory.

As a human-readable string for naming purposes, a label is usually human-specified and locale-dependent (in contrast to purely machine-readable identifiers, IfcIdentifier).

Per ISO 10303-11, the set of characters that may appear in STRINGs is defined in ISO 10646. The encoding of characters in case of file-based exchange is defined in ISO 10303-21 (STEP physical files) and ISO 10303-28 (XML files). Among else, these specifications define the encoding of 8-bit characters from ISO 8859-1…-16 and of 2-byte Unicode characters.

Note that while IfcLabel is restricted to 255 characters, the size in exchange files after encoding may be considerably larger than 255 octets, depending on the particular encoding and on the contents of the label.

class IfcLaborResource : public Ifc2x3::IfcConstructionResource

An IfcLaborResource is used in construction with particular skills or crafts required to perform certain types of construction or management related work.

HISTORY: New Entity in IFC Release 2.0. Base type and documentation extended in IFC 2x4.

IFC2x4 CHANGE: The attribute Skillset has been deleted; use LongDescription to describe the skillset.

The purpose of an IfcLaborResource is to identify a skillset that may be required or used. The skillset identified may be (for instance) chargehand, foreman, labourer, plumbers mate etc. and provides a designation of a particular level of skill. It can be used to identify the generic type of labor resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require a ‘chargehand pipe fitter’. There may be several such labor resources available and so the need to identify which will be used is not necessary at the planning stage.

At a later stage, individual actors can be determined for the labor resources. This is achieved through specifiying the actor through IfcActor. The actor is then identified as the labour resource occurrence through the IfcRelAssignsToResource.RelatedResource attribute. The IfcLaborResource provides the IfcRelAssignsToResource.RelatingResource attribute.

Use definitions for composition, assignment, constraints, time series, and baselines are described at the base type IfcConstructionResource.

Type use definition IfcLaborResource defines the occurrence of any labor resource; common information about labor resource types is handled by IfcLaborResourceType. The IfcLaborResourceType (if present) may establish the common type name, common properties, common productivities for various task types using IfcRelAssignsToProcess. The IfcLaborResourceType is attached using the IfcRelDefinesByType.RelatingType objectified relationship and is accessible by the inverse IsTypedBy attribute.

Quantity use definition The quantities relating to the IfcLaborResource are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following base quantities are defined and should be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities can be defined being subjected to local standard of measurement with another string value assigned to Name and a value provided for MethodOfMeasurement.

Qto_LaborResourceBaseQuantities: base quantities for all labor resources.

Assignment use definition In addition to assignments specified at the base class IfcConstructionResource, a labor resource may have assignments of its own using IfcRelAssignsToResource where RelatingResource refers to the IfcLaborResource and RelatedObjects contains one or more IfcActor subtypes as shown in Figure 194. Such relationship indicates the specific people used as input for the resource. Such actors are nested according to organizational structure with the root organization assigned to the IfcProject. The IfcActor entity is used to represent the people or organizations.

class IfcLibraryInformation : public IfcUtil::IfcBaseEntity

An IfcLibraryInformation describes a library where a library is a structured store of information, normally organized in a manner which allows information lookup through an index or reference value. IfcLibraryInformation provides the library Name and optional Version, VersionDate and Publisher attributes. A Location may be added for electronic access to the library.

NOTE The complete definition of the information in an external library is out of scope in this IFC release.

HISTORY New Entity in IFC2x.

class IfcLibraryReference : public Ifc2x3::IfcExternalReference

An IfcLibraryReference is a reference into a library of information by Location (provided as a URI). It also provides an optional inherited Identification key to allow more specific references to library sections or tables. The inherited Name attribute allows for a human interpretable identification of the library item. Also, general information on the library from which the reference is taken, is given by the ReferencedLibrary relation which identifies the relevant occurrence of IfcLibraryInformation.

The ifcLibraryReference additionally provides the capability to handle multilingual library entries. The Language attribute then holds the language tag for the language used by the strings kept in the Name and the Description attribute.

HISTORY New Entity in IFC2.0.

IFC2x4 CHANGE Description and Language attribute added; ReferencedLibrary attribute added (reversing previous ReferenceIntoLibrary inverse relationship).

Public Types

enum Value

There are three kinds of light distribution curves, according to Standard CEN TC 169, prEN 13032-1, CIE 121:

TYPE_A: Type A is basically not used. For completeness the Type A Photometry equals the Type B rotated 90° around the Z-Axis counter clockwise. TYPE_B: Type B is sometimes used for floodlights. The B-Plane System has a horizontal axis. B-Angles are valid from -180° to +180° with B 0° at the bottom and B180°/B-180° at the top, &#946;-Angles are valid from -90° to +90°. (See Figure 302.) TYPE_C: Type C is the recommended standard system. The C-Plane system equals a globe with a vertical axis. C-Angles are valid from 0° to 360°, &#947;-Angles are valid from 0° (south pole) to 180° (north pole). (See Figure 302.)

class IfcLightDistributionData : public IfcUtil::IfcBaseEntity

IfcLightDistributionData defines the luminous intensity of a light source given at a particular main plane angle. It is based on some standardized light distribution curves; the MainPlaneAngle is either the

A angle; if the IfcLightDistributionCurveEnum is set to TYPE_A B angle; if the IfcLightDistributionCurveEnum is set to TYPE_B C angle; if the IfcLightDistributionCurveEnum is set to TYPE_C

For each MainPlaneAngle (considered as being the row of a table) a list of SecondaryPlaneAngle’s are given (considered to be the columns of a table). They are either the:

&#945; angle; if the IfcLightDistributionCurveEnum is set to TYPE_A &#946; angle; if the IfcLightDistributionCurveEnum is set to TYPE_B &#947; angle; if the IfcLightDistributionCurveEnum is set to TYPE_C

For each pair of MainPlaneAngle and SecondaryPlaneAngle the LuminousIntensity is provided (the unit is given by the IfcUnitAssignment referring to the LuminousIntensityDistributionUnit, normally cd/klm).

class IfcLightFixtureType : public Ifc2x3::IfcFlowTerminalType

The flow terminal type IfcLightFixtureType defines commonly shared information for occurrences of light fixtures. The set of shared information may include:

common properties with shared property sets common representations of shape common materials common composition of elements common ports applicable assignment of process types

It is used to define a light fixture specification (i.e. the specific product information, that is common to all occurrences of that product type). Light Fixture types may be exchanged without being already assigned to occurrences. Occurrences of IfcLightFixtureType are represented by instances of IfcLightFixture.

HISTORY: New entity in IFC2x2

Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the HasPropertySets attribute. Refer to the documentation at the supertype IfcFlowTerminalType and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ElectricalDeviceCommon Pset_LightFixtureTypeCommon Pset_LightFixtureTypeThermal

The following property set definitions are applicable to this entity according to the PredefinedType attribute:

Pset_LightFixtureTypeSecurityLighting (SECURITYLIGHTING)

Material Use Definition The material of the IfcLightFixtureType is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

‘Casing’: Material from which the casing is constructed.

Port Use Definition The distribution ports relating to the IfcLightFixtureType type are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship.
