I might be wrong, but AFIK SurfaceMember are not yet supported. Means no shell elements like slabs and walls.
Furthermore you need to move the structural axis from the FreeCAD Arch object in a way the ends fit together. The stuctural axis is what is exported eventually.
You are right. According to my understandig StructuralSurfaceMember
are not yet supported and the StructuralCurveMember
generated instead on the contour are missing the contour closing member. That's too bad
Hopefully there will be someone with the necessary skills willing to pick up this issue and improve the IFC export. IMO this feature would be extremely important for collaborations in the BIM process.
PS: Just noticed that the StructuralCurveMember
generated for slabs aren't on the structural mid plane but at the lower surface (maybe the plane of the slab BaseObject?).
