I have 6 adjacent Geom_BSplineSurfaces,
I want to create a TopoDS_Solid from these 6 Surfaces
with BRepBuilderAPI_MakeSolid, BRep_Builder, BRepOffsetAPI_Sewing, and other methods.
I can get a TopoDS_Solid, but this is not a real Solid.
When I use it to make some Boolean Operation like
Cut, Common, Fuse, the program always crash.
Has somebody a Idea?
