Research direction

Start by reproducing the export with the attached BSJ-B-BWK-B-R24.zip using Revit 2024.3.0 and IFC for Revit 24.3.0, then inspect the result in Solibri and BIMcollab ZOOM as described. Compare the exported door assembly element positions with Revit; done means the elements are no longer displaced across the reported IFC viewers.
