1. Set the center of the ellipse using the mouse or enter a coordinate in
   the command line.
2. Define the major axis by clicking the endpoint of the axis, which is a
   point on the ellipse. You can also enter a coordinate into the command line
   or enter an angle and major radius in the format @50&lt;30 where 50 is the
   major radius and 30 is the ellipse angle.
3. Define the endpoint of the minor axis which is also a point on the
   ellipse or enter the length of the minor axis.
4. Set the start angle with the mouse or by entering a coordinate or the
   angle in the command line.
5. Set the end angle the same way as the start angle.
