	--          Checks consistency of 2D and 3D representations and keeps

	--          Checks the closure of resulting wire and if it is not closed,
    	--          checks 2D and 3D representation and updates the resulting
    	--          wire to contain only closed representation.
	---Remark : If resulting representation will be 3D, some edges may still
    	--          contain pcurves which are consistent with 3D curves for the
	--          given edge.
