deferred class MakeSweep from BRepPrimAPI inherits MakeShape from BRepBuilderAPI

	---Purpose:  The abstract class MakeSweep is
    	-- the root class of swept primitives.
    	-- Sweeps are objects you obtain by sweeping a profile along a path.
    	-- The profile can be any topology and the path is usually a curve or
    	-- a wire. The profile generates objects according to the following rules:
    	--   -      Vertices generate Edges
    	--   -      Edges generate Faces.
    	--   -      Wires generate Shells.
    	--   -      Faces generate Solids.
    	--   -      Shells generate Composite  Solids.
    	--     You are not allowed to sweep Solids and Composite Solids.
    	-- Two kinds of sweeps are implemented in the BRepPrimAPI package:
    	--   -      The linear sweep called a   Prism
    	--   -      The rotational sweep    called a Revol
    	--   Swept constructions along complex profiles such as BSpline curves
    	-- are also available in the BRepOffsetAPI package..
