Containment : Referencing

Version : 002 (19/06/00)

Definition

In the IFC model IfcRelContains has a dual function. It can be used for containment and for referencing (see IfcRelContains.ContainedOrReferenced). Referencing is used when a container references objects, but does not contain the objects. A space can reference a HVAC duct that passes through the space, but the duct is not contained by the space. The same applies to doors and windows that are associated to a space.

At the moment the concept of 'Containment : Referencing' is used only with spaces. Please see the concept of 'Containment' for the other use of IfcRelContains.
