I notice that the IFC parameter "Operation" within door families if filled in correctly allows for IFC to understand the operation of Revit Doors (useful for doorswings etc). I also see that you can put in extra parameters like "IFCExportAs" and IFCExportType" into your families that control how a family gets categorized when it comes into IFC.
My question is: are there other IFC parameters one can add to Revit families that changes the way that IFC interprets the family.
Im not talking about exporting userdefined property sets: I'm more just trying to understand the relationship between the buildingsmart definitions and what is available within Revit to manipulate these definitions.
If anyone could point me in the correct direction it would be much appreciated
