class MakeRevolutionForm from BRepFeat inherits RibSlot from BRepFeat
---Purpose: MakeRevolutionForm Generates a surface of
-- revolution in the feature as it slides along a
-- revolved face in the basis shape.
-- The semantics of mechanical features is built
-- around giving thickness to a contour. This
-- thickness can either be unilateral - on one side
-- of the contour - or bilateral - on both sides. As
-- in the semantics of form features, the thickness
-- is defined by construction of shapes in specific contexts.
-- The development contexts differ, however,in
-- case of mechanical features. Here they include extrusion:
-- - to a limiting face of the basis shape
-- - to or from a limiting plane
-- - to a height.

---Purpose: a contour W, a shape Sbase and a plane P are initialized to serve as
-- the basic elements in the construction of the rib or groove. The axis Axis of the
-- revolved surface in the basis shape defines the feature's axis of revolution.
-- Height1 and Height2 may be used as limits to the construction of the feature.
-- Fuse offers a choice between:
-- - removing matter with a Boolean cut using the setting 0 in case of the groove
-- - adding matter with Boolean fusion using the setting 1 in case of the rib.
