IfcProductRepresentation

Definition from IAI: The IfcProductRepresentation is a property that defines a property defining a product, including its (geometrical or topological) representation. A product can have zero, one or many of such product representations, and a single product representation can be shared among various products.

NOTE: The definition of this entity relates to the STEP entity property_definition. The use of the term ‘property’ was avoided since it conflicts with the property, property type, and property set definitions elsewhere in the IFC model.
ISSUE: See issue and change log for changes made in IFC Release 1.5 and IFC 2x.
