ABSTRACT This definition may not be instantiated
5.1.3.8.1 Semantic definition
IfcPreDefinedPropertySet is a generalization of all statically defined property sets that are assigned to an object or type object. The statically or pre-defined property sets are entities with a fixed list of attributes having particular defined data types.
Property sets are related to other objects by using the relationship object that refers to the corresponding object:
- Occurrence Object: IfcRelDefinesByProperties using the inverse attribute DefinesOccurrence.
- Type Object: using a direct link by inverse attribute DefinesType.
IfcPreDefinedPropertySet's can be assigned to objects and object types but do not have a defining property set template.

IfcPropertySetDefinition (3) | |||
DefinesType | SET [0:?] OF IfcTypeObject FOR HasPropertySets |
The type object to which the property set is assigned. The property set acts as a shared property set to all occurrences of the type object. |
|
IsDefinedBy | SET [0:?] OF IfcRelDefinesByTemplate FOR RelatedPropertySets |
Relation to the property set template, via the objectified relationship IfcRelDefinesByTemplate, that, if given, provides the definition template for the property set or quantity set and its properties. |
|
DefinesOccurrence | SET [0:?] OF IfcRelDefinesByProperties FOR RelatingPropertyDefinition |
Reference to the relation to one or many object occurrences that are characterized by the property set definition. A single property set can be assigned to multiple object occurrences using the objectified relationship IfcRefDefinesByProperties. |
