    class AppSurface; 
    ---Purpose: Used to Approximate the surfaces.

    deferred class AppFuncRoot;
    ---Purpose: Root Class Function to approximate by AppSurface	 

    class AppFunc;
    ---Purpose: Function to approximate by AppSurface for 
    --          Surface/Surface contact.

    class AppFuncRst;
    ---Purpose: Function  to approximate by AppSurface  for  
    --          Curve/Surface contact.

    class AppFuncRstRst;
    ---Purpose: Function  to approximate by AppSurface  for  
    --          Curve/Curve contact.

    ---Purpose: Function  to approximate by AppSurface  for  
    --          Edge/Face  and  evolutif  radius	 

    class SurfRstConstRad;
    ---Purpose: Copy of CSConstRad with pcurve on surface 
    --          as support. 

    class RstRstEvolRad;
    ---Purpose: Function  to approximate by AppSurface  for  
    --          Edge/Edge  and  evolutif  radius

    --          surface and a curve.

    class SurfPointEvolRadInv;

    ---Purpose: Construction of a BRepBlend_Line between a surface and
    --          a pcurve on surface from an approached
    --          starting solution. The output entries of this builder
    --          are of the same nature as of the traditional walking
    --          but the requirements on the Line are not the same
    --          If the determination of validity range is always
    --          guaranteed, the criteria of correct repartition of sections 
    --          before smoothing are not respected. The resulting Line
    --          is f(t) oriented.

    class RstRstLineBuilder;
    ---Purpose: Construction of a BRepBlend_Line between two pcurves
    --          from an approached starting solution. The output
    --          entries of this builder are of the same nature 
    --          as of a traditional walking, but the requirements 
    --          to the Line are not the same. If the determination of validity range is always
    --          guaranteed, the criteria of correct repartition of sections 
    --          before smoothing are not respected. The resulting Line
