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.
