#### Vision Ellipse

To create a Vision Ellipse:

1. For machines supporting DCC motion, select DCC Mode if you want to create and measure ellipses in DCC mode.

2. Select Auto Ellipse from the Auto Feature toolbar. You can also select the
   Insert | Feature | Auto | Ellipse menu option. This opens the Auto Feature (ellipse) dialog box.

3. With the Auto Feature dialog box open, Select an ellipse in one of two ways:

- CAD Selection Method - From the Cad View, click once near the edge of the ellipse on the CAD surface to establish the ellipse's location.

- Target Selection Method - From the Live View, click to add five points around the ellipse, or double click to automatically add five points equally spaced around the visible ellipse. This establishes the ellipse's location. Adjust the lighting and magnification as needed.

Important: Click as close as possible to the CAD element to ensure the PC-DMIS will not choose an incorrect element.

4. PC-DMIS Vision automatically places the nominal data for the ellipse into the Auto Feature dialog box. The hit targets will automatically be displayed for the ellipse.

5. Adjust the nominal information in the Auto Feature dialog box to match the theoretical values of the ellipse. Also, adjust the values of the Probe Toolbox as needed.

6. Click Test to test ellipse measurement.

7. Click Create on the Auto Feature dialog box to add the ellipse to the part program.

8. Save the part program for future execution. See "A Note on Executing a Vision Part Program".
