Entity definition

The objectified relationship (IfcRelAssociatesDocument) handles the assignment of a document information (items of the select IfcDocumentSelect) to objects occurrences (subtypes of IfcObject) or object types (subtypes of IfcTypeObject).

The relationship is used to assign a document reference or a more detailed document information to objects. A single document reference can be applied to multiple objects.

The inherited attribute RelatedObjects define the objects to which the document association is applied. The attribute RelatingDocument is the reference to a document reference, applied to the object(s).

HISTORY  New entity in IFC2x.
