IfcProductRepresentation

Definition from IAI: The IfcProductRepresentation defines a representation of a product, including its (geometric or topological) representation. A product can have zero, one or many geometric representations, and a single geometric representation can be shared among various products using mapped representations.

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.
HISTORY: New entity in IFC Release 2.0
IFC2x Edition 3 NOTE  Users should not instantiate the entity IfcProductRepresentation from IFC2x Edition 3 onwards. It will be changed into an ABSTRACT supertype in future releases of IFC.
