is
    Create  
    	returns Curve from IntTools;
	---Purpose:
	--- Empty constructor
	---

    Create(Curve3d: Curve from Geom;  
    	   FirstCurve2d : Curve from Geom2d;
    	   SecondCurve2d: Curve from Geom2d)
    	returns Curve from IntTools;
	---Purpose:
	--- Initializes me by a 3d curve
	--- and two 2d curves
	---

    	---Purpose:
	--- Modifier
	---

    SetFirstCurve2d(me: in out;  
    	    	FirstCurve2d: Curve from Geom2d);
    	---C++: inline
	---Purpose:
	--- Modifier

    SetSecondCurve2d(me: in out;  
    	    	SecondCurve2d: Curve from Geom2d);
    	---C++: inline
	---Purpose:
	--- Modifier

    Curve(me)  
    	returns any Curve from Geom;
    	---C++: return const &
	---C++: inline
	---Purpose:
	--- Selector
	---
    
    FirstCurve2d(me)
    	returns any Curve from Geom2d;

	---C++: inline 
	---Purpose:
	--- Selector
	---
	
    HasBounds (me) 
    	returns Boolean from Standard;
	---Purpose:
	--- Returns true if 3d curve is BoundedCurve from Geom
	---

    Bounds    (me; aT1:out Real from Standard;    	  
                   aT2:out Real from Standard;    	  
		   aP1:out Pnt  from gp;     
		   aP2:out Pnt  from gp);
    	---Purpose:
	--- Returns boundary parameters
	--- and corresponded 3d point.
	---
	--  Warning:
	--- If HasBounds returns false
	--- the returned parameters are equal
	--- to zero.
	---

    D0        (me;  
    	       aT1:out Real from Standard; 
               aP1:out Pnt  from gp) 
    	returns Boolean from Standard;
	---Purpose:
	--- Computes 3d point corresponded to parameter aT1
	--- Returns true if given parameter aT1
	--- is inside the boundaries of the curve
	---
     
    Type  (me) 
    	returns CurveType from GeomAbs; 
	---Purpose:
	--- Returns the type of 3d curve
