### Constructing a Projected Ellipse

An ellipse can be projected onto a plane. PC-DMIS projects the centroid of the given feature onto the plane, creating an ellipse. If there is only one input feature, the projection will be to the current work plane. The major diameter of the projected ellipse will be the width of the projected feature, or the probe's diameter (for feature without a defined width). The minor diameter will be the length of the input feature, or of unit 1 (for features without a length defined).

To construct a Projected Ellipse:

1. Access the Construct Ellipse dialog box (Insert | Feature | Constructed | Ellipse).

2. Select the Projection option.

3. Select a feature of any type.

Note: A second feature can also be selected. It must be a plane.

4. Click the Create button.

The Edit window command line for this option would read:
