class NurbsConvert from BRepBuilderAPI inherits ModifyShape from BRepBuilderAPI

	---Purpose: Conversion of the complete geometry of a shape into
    	-- NURBS geometry. For example, all curves supporting
    	-- edges of the basis shape are converted into BSpline
    	-- curves, and all surfaces supporting its faces are
    	-- converted into BSpline surfaces.
