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.
