New Ellipse Options

Ellipse definition

Axis endpoints – Draw the ellipse by specifying both endpoints of the major axis.

Center and end point – Draw the ellipse by specifying the center and one endpoint of the major axis.

Axis length ratio

The ratio of the length of the minor axis to the major axis.

For example, a value of 0.5 produces an ellipse half as tall as it is wide. A value of 1.0 produces a circle.

Sweep

The number of degrees of the ellipse that is drawn.

For example, a value of 180 degrees produces half of a full ellipse. A value of 90 degrees produces a quarter ellipse.

To draw a keypoint ellipse from the center

1. Double-click the Ellipse icon , or choose Ellipse ❒ from the Keypoint Curve Toolbox.
2. Set Ellipse Definition to Center and end point. Click Go.

   

3. Click the center of the ellipse, or type a 3D coordinate to place the point exactly.

   

4. Click the end of the ellipse, or type a 3D coordinate to place the point exactly.

   As you drag the end point, the Ellipse tool displays the length of the two radii in current linear units.

To draw a keypoint ellipse end-to-end

1. Double-click the Ellipse icon , or choose Ellipse ❒ from the Keypoint Curve Toolbox.
2. Set Ellipse Definition to Axis endpoints. Click Go.

   

3. Click the first end of the ellipse, or type a 3D coordinate to place the point exactly.

   

4. Click the opposite end of the ellipse, or type a 3D coordinate to place the point exactly.

   As you drag the end point, the Ellipse tool displays the length of the two axes in current linear units.
