IfcClassificationSelect
¶ IfcClassificationSelect enables selection of whether a classification reference is to be referenced from an external source, or whether a classification is referenced as such.
NOTE Generally, it is expected that selection will be by IfcClassificationReference to identify an individual classification notation that classifies an element in the building information model. For example an element, such as IfcTank, might be further classified by assigning an IfcClassificationReference with Identification = “L6814” and a ClassificationSource identifying the appropriate version of Uniclass. IfcClassification should only be selected in circumstances where there could be a need to indicate the classification system that will be used without associating a notation or reference to an individual object. This may occur for higher level objects such as IfcProject, IfcSystem, or similar. For example an IfcStructuralAnalysisModel might be classified to be applicable to a particular version of EuroCode.

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.

IfcActionRequest
: public Ifc4x1::IfcControl 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.

IfcActuator
: public Ifc4x1::IfcDistributionControlElement An actuator is a mechanical device for moving or controlling a mechanism or system. An actuator takes energy, usually created by air, electricity, or liquid, and converts that into some kind of motion.
HISTORY New entity in IFC2x4
Type Use Definition IfcActuator defines the occurrence of any actuator; common information about actuator types is handled by IfcActuatorType. The IfcActuatorType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcActuatorType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcActuatorType has ports or aggregated elements, such objects are reflected at the IfcActuator occurrence using the IfcRelDefinesByObject relationship.
Property 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 IfcActuatorType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcActuatorType.HasPropertySets. If both are given, then the properties directly defined at IfcActuator override the properties defined at IfcActuatorType. Refer to the documentation at the supertype IfcDistributionControlElement and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)
Pset_ActuatorPHistory (PSET_PERFORMANCEDRIVEN) Pset_ActuatorTypeCommon (PSET_TYPEDRIVENOVERRIDE) Pset_ActuatorTypeLinearActuation (PSET_TYPEDRIVENOVERRIDE) Pset_ActuatorTypeRotationalActuation (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Qto_ActuatorBaseQuantities
Material Use Definition The material of the IfcActuator 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. Material information can also be given at the IfcActuatorType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Casing: Material from which the casing is constructed.
Connection Use Definition The IfcActuator may be connected to other objects as follows using the indicated relationship:
IfcFlowController (IfcRelFlowControlElements): Indicates a connected valve, damper, or switch controlled by the actuator.
Port Use Definition The distribution ports relating to the IfcActuator are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the actuator occurrence is defined by IfcActuatorType, then the port occurrences must reflect those defined at the IfcActuatorType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcActuator PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Input (SIGNAL, SINK): Receives signal.

IfcAdvancedBrep
: public Ifc4x1::IfcManifoldSolidBrep An advanced B-rep is a boundary representation model in which all faces, edges and vertices are explicitly represented. It is a solid with explicit topology and elementaty or free-form geometry. The faces of the B-rep are of type IfcAdvancedFace. An advanced B-rep has to meet the same topological constraints as the manifold solid B-rep. NOTE The advanced B-rep has been introduced in order to support the increasing number of applications that can define and exchange B-rep models based on NURBS or other b-spline surfaces.
NOTE Corresponding ISO 10303-42 entity: advanced_brep_shape_representation. Please refer to ISO/IS 10303-514:1999 for the final definition of the formal standard. There is no explicit entity in ISO 10303-42 for an advanced B-rep, the advanced_brep_shape_representation only ensures that only such kind of manifold B-rep’s are used in a shape representation.
HISTORY New entity in IFC2x4
Informal proposition:
each face is a face surface; each face surface has its geometry defined by an elementary surface, swept surface or a b-spline surface; the edges used to define the boundaries of the face shall all reference an edge curve each curve used to define the geometry of the faces and face bounds shall be either a conic, or a line or a polyline or a b-spline curve the edges used to define the face boundaries shall all be trimmed by vertices of type vertex point no loop used to define a face bound shall be of the oriented subtype
Figure 249 illustrates use of IfcAdvancedBrep for boundary representation models with b-spline surfaces. The diagram shows the topological and geometric representation items that are used for advanced B-reps, based on IfcAdvancedFace.

IfcAdvancedBrepWithVoids
: public Ifc4x1::IfcAdvancedBrep The IfcAdvancedBrepWithVoids is a specialization of an advanced B-rep which contains one or more voids in its interior. The voids are represented as closed shells which are defined so that the shell normal point into the void.
NOTE Corresponding ISO 10303-42 entity: brep_with_voids (see note above). Please refer to ISO/IS 10303-42:1994, p. 173 for the final definition of the formal standard. In IFC advanced B-rep with voids is represented by this subtype IfcAdvancedBrepWithVoids and not defined via an implicit ANDOR supertype constraint as in ISO/IS 10303-42:1994 between an instance of manifold_solid_brep AND brep_with_voids. This change has been made due to the fact, that only ONEOF supertype constraint is allowed within the IFC object model.
HISTORY New entity in IFC2x4
Informal propositions:
Each void shell shall be disjoint from the outer shell and from every other void shell Each void shell shall be enclosed within the outer shell but not within any other void shell. In particular the outer shell is not in the set of void shells Each shell in the IfcManifoldSolidBrep shall be referenced only once. All the faces of all the shells in the IfcAdvancedBrep and the IfcAdvancedBrepWithVoids.Voids shall be of type IfcAdvancedFace.

HISTORY New entity in IFC2x4
Type Use Definition IfcAirTerminal defines the occurrence of any air terminal; common information about air terminal types is handled by IfcAirTerminalType. The IfcAirTerminalType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcAirTerminalType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcAirTerminalType has ports or aggregated elements, such objects are reflected at the IfcAirTerminal occurrence using the IfcRelDefinesByObject relationship. Figure 210 illustrates air terminal type use. Figure 210 — Air terminal type use
Property 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 IfcAirTerminalType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcAirTerminalType.HasPropertySets. If both are given, then the properties directly defined at IfcAirTerminal override the properties defined at IfcAirTerminalType. Refer to the documentation at the supertype IfcFlowTerminal and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_AirTerminalOccurrence (PSET_OCCURRENCEDRIVEN) Pset_AirTerminalPHistory (PSET_PERFORMANCEDRIVEN) Pset_AirTerminalTypeCommon (PSET_TYPEDRIVENOVERRIDE)

They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcAlarmType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcAlarmType.HasPropertySets. If both are given, then the properties directly defined at IfcAlarm override the properties defined at IfcAlarmType. Refer to the documentation at the supertype IfcDistributionControlElement and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_AlarmPHistory (PSET_PERFORMANCEDRIVEN) Pset_AlarmTypeCommon (PSET_TYPEDRIVENOVERRIDE)
Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Qto_AlarmBaseQuantities
Material Use Definition The material of the IfcAlarm 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. Material information can also be given at the IfcAlarmType, defining the common attribute data for all occurrences of the same type. 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 IfcAlarm are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the alarm occurrence is defined by IfcAlarmType, then the port occurrences must reflect those defined at the IfcAlarmType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcAlarm PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Input (SIGNAL, SINK): Receives signal.

IfcAnnotation
: public Ifc4x1::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:
RepresentationIdentifier : ‘Annotation’
RepresentationType : ‘GeometricSet’

IfcAnnotationFillArea
: public Ifc4x1::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.
HISTORY New entity in IFC2x2.

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.

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).

: public Ifc4x1::IfcProfileDef The closed profile IfcArbitraryClosedProfileDef defines an arbitrary two-dimensional profile for the use within the swept surface geometry, the swept area solid or a sectioned spine. It is given by an outer boundary from which the surface or solid can be constructed.
HISTORY: New entity in IFC 1.5. Entity has been renamed from IfcArbitraryProfileDef in IFC Release 2x.
Informal proposition:
The OuterCurve has to be a closed curve. The OuterCurve shall not intersect.
Figure 307 illustrates the arbitrary closed profile definition. The OuterCurve is 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 the xy plane of each list member of IfcSectionedSpine.CrossSectionPositions. The OuterCurve attribute defines a two dimensional closed bounded curve.

IfcAsset
: public Ifc4x1::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.

IfcAsymmetricIShapeProfileDef
: public Ifc4x1::IfcParameterizedProfileDef 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:
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.
