IfcMaterialUsageDefinition | ADDED |
IfcMaterialUsageDefinition is a general supertype for all material related information items in IFC that have occurrence specific assignment parameters to assign a set of materials with shape parameters to a reference geometry item of that component.
There are two ways of assigning a set of materials with shape parameters:
Each instantiable subtype of IfcMaterialUsageDefinition has to be assigned to a subtype of IfcElement by using the objectified relationship IfcRelAssociatesMaterial; it is only valid in conjunction with an element occurrence.
