0044   //! Curve is an adapted curve, that is, an object which is an interface between:
0045   //! -   the services provided by a 3D curve from the package Geom
0046   //! -   and those required of the curve by the computation
0047   //! algorithm which uses it.
0048   //! The adapted curve is created in one of the following ways:
0049   //! -   First sequence:
0050   //! occ::handle<Geom_Curve> myCurve = ... ;
0051   //! occ::handle<GeomAdaptor_Curve>
0052   //! Curve = new
0053   //! GeomAdaptor_Curve(myCurve);
0054   //! -   Second sequence:
0055   //! // Step 1
0056   //! occ::handle<Geom_Curve> myCurve = ... ;
0057   //! GeomAdaptor_Curve Crv (myCurve);
0058   //! // Step 2
0059   //! occ::handle<GeomAdaptor_Curve>
0060   //! Curve = new
0061   //! GeomAdaptor_Curve(Crv);
0062   //! You use the second part of this sequence if you already
0063   //! have the adapted curve Crv.
0064   //! The boundary is then constructed with the Curve object:
0065   //! double Tol = ... ;
0066   //! double dummy = 0. ;
0067   //! myBoundary = GeomFill_SimpleBound
0068   //! (Curve,Tol,dummy);
