The objectified relationship IfcRelAssignsToActor handles the assignment of objects (subtypes of IfcObject) to an actor (subtypes of IfcActor).
The IfcRelAssignsToActor objectified relationship defines a relationship between an IfcActor and one or many objects. A particular role of the actor played in that relationship can be associated. If specified, it takes priority over the role that may be directly assigned to the person or organization.
EXAMPLE An occupant (as an actor) may rent a flat (as a collection of spaces or a zone). This would be an application of this generic relationship.
Reference to the objects (or single object) on which the actor acts upon in a certain role (if given) is specified in the inherited RelatedObjects attribute.
HISTORY New entity in IFC2.0. Has been renamed from IfcRelActsUpon in IFC2x.
