class Ifc4::IfcRelDefinesByProperties : public Ifc4::IfcRelDefines

The objectified relationship IfcRelDefinesByProperties defines the relationships between property set definitions and objects. Properties are aggregated in property sets. Property sets can be either directly assigned to occurrence objects using this relationship, or assigned to an object type and assigned via that type to occurrence objects. The IfcRelDefinesByProperties is a 1-to-N relationship, as it allows for the assignment of one property set to a single or to many objects. Those objects then share the same property definition.

HISTORY New Entity in IFC Release 2.0. Has been renamed from IfcRelAssignsProperties in IFC Release 2x.

IFC2x4 CHANGE The attribute RelatedObjects had been demoted from the supertype IfcRelDefines to IfcRelDefinesByProperties.
