This class is used by the BRepBuilder class to identify objects it creates (faces, edges, etc.).
Assembly: RevitAPI (in RevitAPI.dll) Version: 220.127.116.11 (17.0.484.0)
The user should use these ids to organize the calls to BRepBuilder methods (e.g., addLoop() takes a face id as input, referring to a face that was previously added by a call to AddFace()). The ids are only valid while the BRepBuilder is in use.
