class SimpleBound from GeomFill inherits Boundary from GeomFill 

	---Purpose: Defines a 3d curve as a boundary for a
    	-- GeomFill_ConstrainedFilling algorithm.
    	-- This curve is unattached to an existing surface.D
      -- Contains fields to allow a reparametrization of curve.

    returns SimpleBound from GeomFill;

    	--- Purpose:
    	-- Constructs the boundary object defined by the 3d curve.
    	-- The surface to be built along this boundary will be in the
    	-- tolerance range defined by Tol3d.
    	-- This object is to be used as a boundary for a
    	-- GeomFill_ConstrainedFilling framework.
    	-- Dummy is initialized but has no function in this class.
    	-- Warning
    	-- Curve is an adapted curve, that is, an object which is an interface between:
    	-- -   the services provided by a 3D curve from the package Geom
    	-- -   and those required of the curve by the computation
    	--   algorithm which uses it.
    	-- The adapted curve is created in one of the following ways:
    	-- -   First sequence:
    	-- Handle(Geom_Curve) myCurve = ... ;
    	-- Handle(GeomAdaptor_HCurve)
    	--     Curve = new
    	-- GeomAdaptor_HCurve(myCurve);
    	-- -   Second sequence:
    	-- // Step 1
    	-- Handle(Geom_Curve) myCurve = ... ;
    	-- GeomAdaptor_Curve Crv (myCurve);
    	-- // Step 2
    	-- Handle(GeomAdaptor_HCurve)
    	--     Curve = new
    	-- GeomAdaptor_HCurve(Crv);
    	-- You use the second part of this sequence if you already
    	-- have the adapted curve Crv.
    	-- The boundary is then constructed with the Curve object:
    	-- Standard_Real Tol = ... ;
    	-- Standard_Real dummy = 0. ;
    	-- myBoundary = GeomFill_SimpleBound
    	-- (Curve,Tol,dummy);
