Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Property Value
ReferenceThis value may be if the object does not store a corresponding reference. This might be due to any of the following reasons:
- The face was obtained from an API member which does not permit options to generate corresponding References (most API members, besides Element.Geometry, do not have an option to generate a Reference).
- The corresponding geometry object does not permit referencing.
