class Curve from IntTools
      ---Purpose: class is a container of
      --          one 3d curve
      --          two 2d curves

uses
    Curve from Geom,
    Curve from Geom2d,
    Pnt  from gp, 
    CurveType from GeomAbs
is
    Create  
    	returns Curve from IntTools;
	---Purpose:
	--- Empty constructor
	---

    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.
	---

    	       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
