0053   //! -   and those required of the curve by the computation
0054   //! algorithm which uses it.
0055   //! The adapted curve is created in one of the following ways:
0056   //! -   First sequence:
0057   //! Handle(Geom_Curve) myCurve = ... ;
0058   //! Handle(GeomAdaptor_Curve)
0059   //! Curve = new
0060   //! GeomAdaptor_Curve(myCurve);
0061   //! -   Second sequence:
0062   //! // Step 1
0063   //! Handle(Geom_Curve) myCurve = ... ;
0064   //! GeomAdaptor_Curve Crv (myCurve);
0065   //! // Step 2
0066   //! Handle(GeomAdaptor_Curve)
0067   //! Curve = new
0068   //! GeomAdaptor_Curve(Crv);
0069   //! You use the second part of this sequence if you already
0070   //! have the adapted curve Crv.
0071   //! The boundary is then constructed with the Curve object:
0072   //! Standard_Real Tol = ... ;
0073   //! Standard_Real dummy = 0. ;
0074   //! myBoundary = GeomFill_SimpleBound
