private class ApproxSeewing from BRepFill 

	---Purpose: Evaluate the 3dCurve  and the PCurves described in
	--          a MultiLine from BRepFill.  The parametrization of
	--          those curves is  not  imposed by  the Bissectrice.
	--          The  parametrization  is given  approximatively by
	--          the abscissa of the curve3d.
