When I export an IFC from Revit, the IfcGuid parameter for rooms keeps changing with each export.
In my search I came across this github issue [1].
However, I still have the same problem that the IfcGuid for a room changes with each export.
Referring to the IFC file, it contains the following header
HEADER; FILE_DESCRIPTION(('ViewDefinition [CoordinationView_V2.0, QuantityTakeOffAddOnView]'),'2;1'); FILE_NAME('7000-BS11','2023-12-03T13:13:22+01:00',(''),(''),'ODA SDAI 22.12','23.0.11.19 - Exporter 23.0.11.19 - Alternative UI 23.0.11.19',''); FILE_SCHEMA(('IFC2X3')); ENDSEC;`
It looks like I'm running v23, which should have fixed this (according to github), but it didn't.
I am using Revit 2023.
