is

	Create returns CurveOnSurface;
	---Purpose : Returns a CurveOnSurface SelectType

	CaseNum (me; ent : Transient) returns Integer;
	---Purpose: Recognizes a CurveOnSurface Kind Entity that is :
	--        1 -> Pcurve
	--        2 -> SurfaceCurve
	--        3 -> CompositeCurveOnSurface
	--        0 else

	Pcurve (me) returns any Pcurve;
	---Purpose : returns Value as a Pcurve (Null if another type)

	SurfaceCurve (me) returns any SurfaceCurve;
	---Purpose : returns Value as a SurfaceCurve (Null if another type)

	CompositeCurveOnSurface (me) returns any CompositeCurveOnSurface;
	---Purpose : returns Value as a CompositeCurveOnSurface (Null if another type)
