Move the crosshairs around the center of the ellipse and click. If you enter a
value, the higher the value, the greater the eccentricity of the ellipse. Entering
0 defines a circular ellipse.
Arc
Creates an elliptical arc.
The angle of the first axis determines the angle of the elliptical arc. The first
axis can define either the major or the minor axis depending on its size.
The first two points of the elliptical arc determine the location and length of
the first axis. The third point determines the distance between the center of
the elliptical arc and the endpoint of the second axis. The fourth and fifth
points are the start and end angles.
Axis Endpoint Defines the start point of the first axis.
Rotation Defines the major to minor axis ratio of the ellipse by rotating a
circle about the first axis. The higher the value from 0 through 89.4 degrees,
the greater the ratio of minor to major axis. Values between 89.4 degrees and
90.6 degrees are invalid because the ellipse would otherwise appear as a straight
line. Multiples of these angle values result in a mirrored effect every 90 degrees.
Start Angle Defines the first endpoint of the elliptical arc. The Start Angle
option toggles from Parameter mode to Angle mode. The mode controls how
the ellipse is calculated.
