class ShapeConvertToBezier from ShapeUpgrade inherits ShapeDivide from ShapeUpgrade

	---Purpose: API class for performing conversion of 3D, 2D curves to bezier curves
	--          and surfaces to bezier based surfaces (

	--           surface of revolution based on bezier curve,
	--           offset surface based on any previous type).
