0041 //!
0042 //! Create(C : TheCurve)
0043 //!
0044 //! Makes an edge on  the whole curve.  Add vertices
0045 //! on finite curves.
0046 //!
0047 //! Create(C : TheCurve; p1,p2 : Real)

0049 //! Make an edge  on the curve between parameters p1
0050 //! and p2. if p2 < p1 the edge will be REVERSED. If
0051 //! p1  or p2 is infinite the  curve will be open in
0052 //! that  direction. Vertices are created for finite
0053 //! values of p1 and p2.
0054 //!
0055 //! Create(C : TheCurve; P1, P2 : Pnt2d from gp)
0056 //!
0057 //! Make an edge on the curve  between the points P1
0058 //! and P2. The  points are projected on   the curve
0059 //! and the   previous method is  used. An  error is
0060 //! raised if the points are not on the curve.
0061 //!
0062 //! Create(C : TheCurve; V1, V2 : Vertex from TopoDS)
0063 //!
0064 //! Make an edge  on the curve  between the vertices
0065 //! V1 and V2. Same as the  previous but no vertices
0066 //! are created. If a vertex is  Null the curve will
