class Pipe from BRepFill 

	---Purpose: Create a  shape by sweeping a shape  (the profile)
	--          along a wire (the spine).
	--          
	--          For each edge  or vertex from the spine  the  user
	--          may ask for the shape generated from each subshape
	--          of the profile.
