Semantic definitions at the entity

Entity definition

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.

4	CompositeProfile	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.	X
