This class implements the following algorithms used to
create Ellipse from gp.
* Create an Ellipse from two apex and the center.
Defines an ellipse in 2D space.
The parametrization range is [0,2*PI].
The ellipse is a closed and periodic curve.
The center of the ellipse is the "Location" point of its
axis placement "XAxis".
The "XAxis" of the ellipse defines the origin of the
parametrization, it is the major axis of the ellipse.
The YAxis is the minor axis of the ellipse.

GCE2d_MakeEllipse (const gp_Elips2d &E) | |
Creates an ellipse from a non persistent one from package gp | |
GCE2d_MakeEllipse (const gp_Ax2d &MajorAxis, const Standard_Real MajorRadius, const Standard_Real MinorRadius, const Standard_Boolean Sense=Standard_True) | |
MajorAxis is the local coordinate system of the ellipse. It is the "XAxis". The minor axis is the YAxis of the ellipse. Sense give the sense of parametrization of the Ellipse. It is not forbidden to create an ellipse with MajorRadius = MinorRadius. The status is "InvertRadius" if MajorRadius < MinorRadius or "NegativeRadius" if MinorRadius < 0. | |
GCE2d_MakeEllipse (const gp_Ax22d &Axis, const Standard_Real MajorRadius, const Standard_Real MinorRadius) | |
Axis is the local coordinate system of the ellipse. It is not forbidden to create an ellipse with MajorRadius = MinorRadius. The status is "InvertRadius" if MajorRadius < MinorRadius or "NegativeRadius" if MinorRadius < 0. | |
GCE2d_MakeEllipse (const gp_Pnt2d &S1, const gp_Pnt2d &S2, const gp_Pnt2d &Center) | |
Make an Ellipse centered on the point Center, where | |
const Handle_Geom2d_Ellipse & | Value () const |
Returns the constructed ellipse. Exceptions StdFail_NotDone if no ellipse is constructed. | |
