8.10.3.10 IfcMaterialList

8.10.3.10.1 Semantic definitions at the entity

IfcMaterialList is a list of the different materials that are used in an element.

NOTEĀ  The class IfcMaterialList will normally be used where an element is described at a more abstract level. For example, for an architectural specification writer, the only information that may be needed about a concrete column is that it contains concrete, reinforcing steel and mild steel ligatures. It shall not be used for elements consisting of material layers when the different layers can be defined and the class IfcMaterialLayerSet can be used. Also, IfcMaterialList shall not be used for elements consisting of a single identifiable material (for example, to represent anisotropic material).

IFC4 CHANGEĀ  The entity IfcMaterialList is deprecated and shall no longer be used. Use IfcMaterialConstituentSet instead.
