 Make an arc of Parabola (TrimmedCurve from Geom2d) from
a Parabola between two parameters Alpha1 and Alpha2.

 GCE2d_MakeArcOfParabola (const gp_Parab2d &Parab, const gp_Pnt2d &P, const Standard_Real Alpha, const Standard_Boolean Sense=Standard_True)
 Make an arc of Parabola (TrimmedCurve from Geom2d) from
a Parabola between point.
 GCE2d_MakeArcOfParabola (const gp_Parab2d &Parab, const gp_Pnt2d &P1, const gp_Pnt2d &P2, const Standard_Boolean Sense=Standard_True)

  • the trigonometric sense if Sense is not defined
    or is true (default value), or
  • the opposite sense if Sense is false.

IsDone always returns true.
