Hello, Many BuiltInParameters would need to be mapped like theses pretty obvious one from Pset_AirTerminalOccurrence : Revit : RBS_SYSTEM_CLASSIFICATION_PARAM => Ifc : AirflowType Revit : RBS_DUCT_FLOW_PARAM => Ifc : AirFlowRate This post is very old and it seems that it hasn't gone forward a lot. Is there some reason ? Is there something we can do ? Filing collaborativly a sheet with mappings ? Do we have any chance to get the same thing at IFC import ? In order to get workable objects ?
