Assigns To Actor (FP)

Overview

Describes a relationship in which a set of objects are assigned to an actor. This may be for the purposes of ownership or for a particular actor fulfilling a designated role (specified through the functional part fp_model_actor) for a set of objects.

An example of usage is where a series of spaces within a building, each of whose type is designated as 'OFFICE', are assigned to an actor who has the role 'LESSEE' to indicate that he/she is leasing the space

Note that other assignment relationships can also be used to handle the assignment of an actor to an object. This method should be used for individual or multiple actor assignments to individual objects.

Description	Entity/Pset/Functional Part	MAN	REC	OPT
Set the occurrence of the parent actor in the relationship This assumes that selection of the actor as person and/or organization has been made and that actor roles have been defined as specified in the functional part fp_model_actor.	IfcActor
Set the occurrences of the child entities in the relationship	IfcObject <child subtypes>
Assert the parent relationship	IfcRelAssignsToActor.RelatingActor -> IfcActor
Assert the child relationship	IfcRelAssignsToActor.RelatedObjects -> IfcObject
Assert the type of related objects from the predefined list if required This value can be used to identify the parent supertype of related objects as e.g. product, group, process, control etc. If the related objects have mixed supertypes, then the value .NOTDEFINED. should be used.	IfcRelAssignsToActor.RelatedObjectsType -> IfcObjectTypeEnum
Assert the owner history of the relationship	IfcRelAssignsToActor.OwnerHistory -> fp_apply_owner_history
