8.10.3.12.1 Semantic definitions at the entity

The IfcMaterialProfileSet is a designation by which individual material(s) of a prismatic element (for example, beam or column) constructed of a single or multiple material profiles is known.

NOTE  In case of multiple MaterialProfiles, the relative positioning of individual profiles in IfcMaterialProfileSet are defined using the concept of IfcCompositeProfileDef in IfcProfileResource schema; otherwise, only one MaterialProfile is given and defined by an individual IfcProfileDef (subtype).

HISTORY New entity in IFC4.

8.10.3.12.1 Attributes

# Attribute Type Description
IfcMaterialDefinition
AssociatedTo SET [0:?] OF IfcRelAssociatesMaterial FOR RelatingMaterial Use of the IfcMaterialDefinition subtypes within the material association of an element occurrence or element type. The association is established by the IfcRelAssociatesMaterial relationship.

> IFC4 CHANGE  The inverse attribute has been added.
HasExternalReferencesSET [0:?] OF IfcExternalReferenceRelationship FOR RelatedResourceObjectsReference to external references, e.g. library, classification, or document information, that are associated to the material.

> IFC4 CHANGE  The inverse attribute has been added.
HasProperties SET [0:?] OF IfcMaterialProperties FOR Material Material properties assigned to instances of subtypes of IfcMaterialDefinition.

> IFC4 CHANGE  The inverse attribute has been added.
IfcMaterialProfileSet
1 Name OPTIONAL IfcLabel The name by which the material profile set is known.
2 Description OPTIONAL IfcText Definition of the material profile set in descriptive terms.
3 MaterialProfiles LIST [1:?] OF IfcMaterialProfile Identification of the profiles from which the material profile set is composed.
4 CompositeProfile OPTIONAL IfcCompositeProfileDef Reference to the composite profile definition for which this material profile set associates material to each of its individual profiles. If only a single material profile is used (the most typical case) then no CompositeProfile is asserted.

> NOTE  The referenced IfcCompositeProfileDef instance shall be composed of all of the IfcProfileDef instances which are used via the MaterialProfiles list in the current IfcMaterialProfileSet.
