deferred generic class PSurfaceTool from IntStart
    (ThePSurface as any)
                                   

	---Purpose: Template class for a tool on a bi-parametrised
	--          surface.
	--          It is possible to implement this class with an 
	--          instantiation of the SurfaceTool from Adaptor3d.



is

    UIntervalFirst(myclass ; S: ThePSurface)
	   
	---Purpose: Returns the first U parameter of the surface.

    	returns Real from Standard;
    
    
    VIntervalFirst(myclass ; S: ThePSurface)
	   
	---Purpose: Returns the first V parameter of the surface.

    	returns Real from Standard;
    
    
    UIntervalLast(myclass ; S: ThePSurface)
	   
	---Purpose: Returns the last U parameter of the surface.

    	returns Real from Standard;
    
    
    VIntervalLast(myclass ; S: ThePSurface)
