Hello,
We encounter a modified GUID problem when exporting space boundaries in a IFC 2x3 file from Revit, betwen two export.
It seems that the GUID of these objects (IfcRelSpaceBoundary) is systematically generated again during the export, instead of being preserved and identical. Is it possible to make this GUID identical?
This issue has been replicated with the latest updates from Revit (2020.1) and the IFC 2020 (20.1.0) application, but it was already present in precedent versions.
You will find attached the test project used, as well as the generated IFC files, in ifc2x3.
Best regards,
Romain
