Creates an ellipse or an elliptical arc.
Button
The first two points of the ellipse determine the location and length of the first axis. The third point determines the distance between the center of the ellipse and the end point of the second axis.
The following prompts are displayed.
Specify axis endpoint of ellipse or [ Arc/ Center/ Isocircle]: Specify a point or enter an option
Defines the first axis by its two endpoints. The angle of the first axis determines the angle of the ellipse. The first axis can define either the major or the minor axis of the ellipse.
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.
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.
Requires the same input as Start Angle, but creates the elliptical arc using the following parametric vector equation:
p(u) = c + a * cos(u) + b * sin(u)
where c is the center of the ellipse and a and b are its major and minor axes, respectively.
Creates an ellipse using a center point, the endpoint of the first axis, and the length of the second axis. You can specify the distances by clicking a location at the desired distance or by entering a value for the length.
