class TFace from BRep inherits TFace from TopoDS

	---Purpose: The Tface from BRep  is  based  on the TFace  from
	--          TopoDS. The TFace contains :
	--          
	--          * A suface, a tolerance and a Location.
	--          
	--          * A NaturalRestriction flag,   when this  flag  is
	--          True the  boundary of the  face is known to be the
	--          parametric space (Umin, UMax, VMin, VMax).
	--          
	--          *  An    optional Triangulation.   If  there  is a
	--          triangulation the surface can be absent.
	--          
	--          The  Location is  used   for the Surface.
	--          
	--          The triangulation  is in the same reference system
	--          than the TFace.     A point on mySurface must   be
	--          transformed with myLocation,  but  not a point  on
	--          the triangulation.
	--          
	--          The Surface may  be shared by different TFaces but
	--          not the  Triangulation, because the  Triangulation
	--          may be modified by  the edges. 
	--
