class Ifc4x2::IfcPlateType : public Ifc4x2::IfcBuildingElementType

The element type IfcPlateType defines commonly shared information for occurrences of plates. The set of shared information may include:

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

NOTE It is illegal to share shape representations as representation maps for occurrences of IfcPlateStandardCase.

It is used to define a plate specification (i.e. the specific product information, that is common to all occurrences of that product type). Plate types may be exchanged without being already assigned to occurrences. 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. The occurrences of the IfcPlateType within building models are represented by instances of IfcPlateStandardCase if the IfcPlateType has a single associated IfcMaterialLayerSet; otherwise they are represented by instances of IfcPlate.

HISTORY New entity in Release IFC2x2.

Informal proposition:

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

Material Use Definition The material of the IfcPlateType 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. Note: It is illegal to assign an IfcMaterial to an IfcPlateType, if there is at least one occurrences of IfcPlateStandardCase for this type. Layer Set Use Definition: The shared material layer set definition is defined by assigning an IfcMaterialLayerSet (see material use definition above). The IfcMaterialLayer refers to one or several of IfcMaterial that is the common for all plate occurrence, if used. It is only applicable if the IfcPlateType has only occurrences of type IfcPlateStandardCase (see definition of IfcPlateStandardCase for further information). NOTE Since each individual instance of IfcPlateStandardCase defines its own IfcMaterialLayerSetUsage including the offset from the reference plane, the same IfcPlateType can be used independently of the reference plane alignment of its occurrences. Property Set Use Definition: The shared property sets relating to the IfcPlateType are defined by the IfcPropertySet and are attached by the HasPropertySets attribute. The following property set definitions specific to the IfcWallType are part of this IFC release: NOTE There is no differentiation between properties within the property set that are only assignable to IfcPlateType and those that are only assignable to IfcPlate. If the same property is assigned to the IfcPlateType and the IfcPlate being an occurrence of the IfcPlateType, then the occurrence property overrides the type property.

Pset_PlateCommon: common property set for all plate types.
