class BSplineSurface  from DrawTrSurf 

inherits Surface from DrawTrSurf

        --- Purpose :
        --  This class defines a drawable BSplineSurface. 
        --  With this class you can draw the control points and the knots 
        --  of the surface.
        --  You can use the general class Surface from DrawTrSurf too,
        --  if you just want to sea boundaries and isoparametric curves.
