uses

    Shape from TopoDS,    
    Face from TopoDS,
    Edge from TopoDS,
    Pnt from gp,
    Curve from Geom,
    Surface from Geom,
    Surface from BRepAdaptor,
    Curve from BRepAdaptor,
    Dir from gp

is

    Tolerance(myclass; S : Shape from TopoDS ) 
    ---Purpose: Returns the tolerance of the shape <S>.
    --          If the shape <S> is Null, returns 0.
    returns Real from Standard;

    Pnt(myclass; S : Shape from TopoDS ) 
    ---Purpose: Returns 3D point of vertex <S>.
    returns Pnt from gp;

    BASISCURVE(myclass; C : Curve from Geom)
    returns Curve from Geom;

    BASISCURVE(myclass; E : Edge from TopoDS)
    returns Curve from Geom;

    BASISSURFACE(myclass; S : Surface from Geom)
    returns Surface from Geom;

    BASISSURFACE(myclass; F : Face from TopoDS)
    returns Surface from Geom;

    UVBOUNDS(myclass; S : Surface from Geom; 
    	    	       UPeri, VPeri : in out Boolean from Standard;
    	    	       Umin, Umax, Vmin, Vmax : in out Real from Standard);

    UVBOUNDS(myclass; F : Face from TopoDS;
    	    	       UPeri, VPeri : in out Boolean from Standard;
    	    	       Umin, Umax, Vmin, Vmax : in out Real from Standard);

    AdjustOnPeriodic(myclass; S : Shape from TopoDS;
		              u,v : in out Real from Standard);
    ---Purpose: ajust u,v values in UVBounds of the domain of the 
    --          geometric shape <S>, according to Uperiodicity and 
    --          VPeriodicity of the domain.
    --          <S> is assumed to be a face.
    --          u and/or v is/are not modified when the domain is
    --          not periodic in U and/or V .

    	    	      T,N : out Dir from gp;        -- tangent, normal
    	    	      C   : out Real from Standard) -- curvature
    ---Purpose : 
    -- Compute tangent T, normal N, curvature C at point of parameter
    -- P on curve BRAC. Returns the tolerance indicating if T,N are null.
    returns Real from Standard;
