PR: auto-generated building element proxy type
Problem Description
There seems to be a case where Revit auto generates a bunch of IfcBuildingElementProxy elements, each with its own IfcBuildingElementProxyType. I believe in this case it is some sort of curtain wall reveal or other profile being used as part of a curtain wall. This ends up with a model with hundreds of IfcBuildingElementProxyTypes. They cannot be edited in Revit (i.e. cannot set IfcExportAs) so we cannot set any properties.
This means that clients will see a bunch of generic proxy elements missing all the data that they request.

Hello @Moult,
Thank you for reporting this issue and for providing the helpful screenshot, which clearly illustrated the problem of numerous IfcBuildingElementProxyType entities being generated.
We have attempted to reproduce this behavior on our side with current Revit and IFC Exporter versions, but we have not been able to consistently reproduce the issue without a specific sample file. We also note that several similar problems related to complex geometry export and type generation have received fixes in recent Revit updates.
Could you please confirm if you are still experiencing this problem with your current Revit and IFC Exporter versions?
If the issue does still reproduce for you, to help us investigate and resolve this more effectively, please provide:
- A sample Revit file (
.rvt) that consistently exhibits this problematic behavior (especially a simplified version focusing on the curtain wall reveals or profiles that cause the issue). - Detailed, step-by-step instructions on how to reproduce the issue using your provided file, including any specific family settings or export configurations that might be relevant.
Providing these details will greatly assist us in identifying the root cause and accelerating a fix.
Thank you for your cooperation!
