IfcPropertyDefinition

IfcPropertyDefinition

Definition from IAI: The IfcPropertyDefinition defines the generalization of all characteristics (i.e. a grouping of individual properties), that may be assigned to objects. Property definitions can be property set definitions, or type objects.

Property definitions define information that is shared among multiple instances of objects. The assignment of the shared information to objects is handled by the IfcRelDefines relationship.
