When I make a ifc of walls, windows and doors, and I open it in Revit, the windows and doors are tilted in Revit.
This only happens when I use a wall with compositions.
In the attached dwg-file I have two walls, one with compositions, one without compositions.
In the attached jpg-file you can see the result in Revit.
The ifc-viewers Solibri, Tekla and BIM Vision show both walls, windows and doors correct !
I use Windows 10, BricsCAD BIM 19.2.14 and Revit 2020.
The used composition, window and door are from the BricsCAD library.
