    class BuildAveragePlane;
    --- Purpose:
    --  this class computes the initial surface (average plane) in the cases when the initial surface is not 
    --  given.

    class Surface;
    ---Purpose:
    -- this class describes the characteristics of the plate surface
    
    class MakeApprox;
    ---Purpose:
    -- this class converts a GeomPlate_Surface to a Geom_BSplineSurface

    ---Purpose:
    -- inherits class Criterion from AdvApp2Var ;
    -- this class contains a specific G0 criterion for GeomPlate_MakeApprox

    class PlateG1Criterion;
    ---Purpose:
    -- inherits class Criterion from AdvApp2Var ;
    -- this class contains a specific G1 criterion for GeomPlate_MakeApprox
