class MakeRevol from BRepPrimAPI inherits MakeSweep from BRepPrimAPI

	---Purpose: Class to make revolved sweep topologies.
	--          
	--          a revolved sweep is defined by :
	--          
	--          * A basis topology which is swept.
	--          
	--            The   basis topology  must   not  contain solids
	--            (neither composite solids.).
	--            
	--            The basis topology  may be copied  or  shared in
	--            the result.
	--            
	--          * A rotation axis and angle :
	--          
	--            - The axis is an Ax1 from gp.
	--            
	--            - The angle is in [0, 2*Pi].
	--            
	--            - The angle default value is 2*Pi.
	--          
	--          
	--          The result is a topology with a higher dimension :
	--          
	--            - Vertex -> Edge.
	--            - Edge   -> Face.
	--            - Wire   -> Shell.
	--            - Face   -> Solid.
	--            - Shell  -> CompSolid.
	--            
	--            Sweeping a Compound sweeps  the elements  of the
	--            compound  and creates    a  compound with    the
	--            results. 
	--
