generic class PolyhedronTool from IntCurveSurface
    (ThePolyhedron as any) -- as Polyhedron from IntCurveSurface

    ---Purpose: Describe the signature  of  a polyhedral  surface with
    --          only triangular facets and the  necessary informations
    --          to compute the interferences.

is  


    Bounding       (myclass; thePolyh : ThePolyhedron)
    	---Purpose: Give the bounding box of the PolyhedronTool.
    	---C++: return const &
    	---C++: inline
    returns Box from Bnd;


    ComponentsBounding
       	    	   (myclass; thePolyh : ThePolyhedron)    	    	    
    	---Purpose: Give the array of boxes. The box <n> corresponding 
    	--          to the triangle <n>.
    	---C++: return const &

    NbTriangles	   (myclass; thePolyh : ThePolyhedron) 
    	    	    returns Integer from Standard;
    ---Purpose: Give the number of triangles in this polyedral surface.
    ---C++: inline

		    Index     : in Integer from Standard;
		    P1,P2,P3  : out Integer from Standard)
		    raises OutOfRange from Standard;
    ---Purpose: Give the indices  of  the 3 points of  the triangle of
    --          address Index in the PolyhedronTool.
    ---C++: inline


    Point	   (myclass; thePolyh : ThePolyhedron;
		    Index : in Integer)
		    returns Pnt from gp
		    raises OutOfRange from Standard;
    ---Purpose: Give the point of index i in the polyedral surface.
    ---C++: return const &

		    TriCon	 : out Integer;
		    OtherP	 : out Integer)
		    returns Integer
		    raises OutOfRange from Standard;
    ---Purpose: Give the  addresse Tricon of   the triangle connexe to
    --          the triangle of address Triang by the edge Pivot Pedge
    --          and the third point of this  connexe triangle. When we
    --          are on  a free edge TriCon==0  but the function return
    --          the value of  the triangle in the  other side of Pivot
    --          on the free edge.  Used to turn around a vertex.

    ---Purpose: This method returns true if the edge based on points with 
    --          indices Index1 and Index2 represents a boundary edge. It is 
    --          necessary to take into account the boundary deflection for
