---Purpose:

-- 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.

---Purpose: returns the Offset surface computed from the
|
|
-- surface <Surface> at an OffsetDistance <Offset>.
|
|
--
|
|
-- If possible, this method returns the real type of
|
|
-- the surface ( e.g. An Offset of a plane is a plane).
|
|
--
|
|
-- If no particular case is detected, the returned
|
|
-- surface will have the Type Geom_OffsetSurface.
