I have exported the demo model from Revit to BlenderBIM with 2nd level space boundaries (https://github.com/maxtillberg/ICEBridge/blob/main/RAC_basic_sample_project_spaces.ifc) but there are 3 problems when I import the IFC into BlenderBIM and I wonder how I can determine if the problem is in the Revit export or in the import into Blender? The problems are:
-
No IfcRelSpaceboundaries for the curtain panels
-
The big space bounding column has no IfcRelSpaceboundaries (marked in red)
-
The geometrical presentation for two of the walls overlaps partly with the windows (selected wall in the image).
