No feedback yet? It's a very old issue and I believe an important one. It also seems that is closely related to these issues/topics as well: https://sourceforge.net/p/ifcexporter/discussion/general/thread/64525b95/ and https://sourceforge.net/p/ifcexporter/discussion/general/thread/4351a1bb/ We would really appreciate any feedback on this, since it is really important if we could preserve any relation between a host family and its nested/shared families when the Revit file is exported into IFC

Any update on this topic now? It's been a while, is there any progress or roadmaps for this?

Is there any mapping file or explanation for Export IFC common property sets process in Revit? There is a lot of common Psets specified for each IfcEntity in BuildingSmart standard, especially for IFC 4.3, however, there's no clear guide how some of these Psets are exported and mapped from Revit since currently great number of Revit Categories don't have respective properties by default. (e.g. IsExternal). I'm really interested how Beams, Structural Columns, Windows, etc. get this property if "Export...

It's been a while but this topic is still very important. Is there any feedback on the progress?

Thanks for reply. Clear explanation, however for a common user I believe that the acceptable solution would be exporting a Function value as a respective string since the string value is the value originally selected in the authoring tool (I don't think that common user understand or remembers which number corresponds to which string, especially if it's not explicitly marked).

Is there any way to successfully export a value of the "Function" property used in Revit for (walls, floors, doors, etc.)? I've tried to export this property using almost all data types but without success. If I understand correctly the accurate data type for this property is Identifier (when exported using Revit property sets), but If I try to use custom property set - the property is not exported. I've made to export it using Integer and Real data types, but exported value is number instead of...
