IfcMaterialConstituentSet: public Ifc4x3_rc1::IfcMaterialDefinition¶
IfcMaterialConstituentSet is a collection of individual material constituents, each assigning a material to a part of an element.

An IfcMaterialConstituentSet is assigned to the window with two IfcMaterialConstituent’s, one with the Name = ‘Lining’, one with the Name = ‘Glazing’. NOTE See the “Material Use Definition” at the individual element to which an IfcMaterialConstituentSet may apply for a required or recommended definition of such keywords.
