IfcActorRole

Semantic definitions at the entity

Entity definition

This entity indicates a role which is performed by an actor, either a person, an organization or a person related to an organization.

NOTE The list of roles of the enumeration values of the Role attribute can never be complete. Therefore using enumeration value USERDEFINED, the user can provide any role as a value of the attribute UserDefinedRole.

NOTE Entity adapted from organization_role and person_role defined in ISO 10303-41.

HISTORY New entity in IFC1.5.1.
