IfcAdvancedFace: cylindrical surface with winding loops

Attached examples of two faces with winding loops.
I did not find any application can read it and looking for developers response (well, maybe the issue is in my IFC)


Face 1.ifc (34.7 KB)
Face 2.ifc (34.6 KB)

This is how I expected to see the files.
Face 1 solid RV.ifc (37.8 KB)
Face 2 solid RV.ifc (37.5 KB)

Face 1 - expected
Face 2 - expected

Generally who is implementing NURBS?
Do we need separate forum thread with examples and discussion?
