| | Lists the offset modes. These are the following:
- BRepOffset_Skin which describes the offset along
the surface of a solid, used to obtain a manifold topological space,
- BRepOffset_Pipe which describes the offset of a
curve, used to obtain a pre-surface,
- BRepOffset_RectoVerso which describes the offset
of a given surface shell along both sides of the surface.
//! status of an offset face
Good :
Reversed : e.g. Offset > Radius of a cylinder
Degenerated : e.g. Offset = Radius of a cylinder
Unknown : e.g. for a Beziersurf
