IFC 4.3.x development IfcProductRepresentation

Change log


modificationsabstractChanged from False to True Semantic definitions at the entity

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 ISO 10303 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 IFC2.0
