Draws an ellipse.
You can draw a complete ellipse or an Elliptical Arc.

1 
<Axis endpoint 1> 
2 
Axis endpoint 2 
3 
Either:
<Other axis endpoint>
 or 
a 
Rotation 
b 
Rotation around major axis 

 or 
1 
Center 
2 
Axis endpoint 2 
3 
Either:
<Other axis endpoint>
 or 
a 
Rotation 
b 
Rotation around major axis 

Rotation defines the major to minor axis ratio by rotating a circle about the first axis. The higher the value (0 to 89.4 degrees), the greater the ratio of minor to major axis. A ratio of 0 defines a circle.
