#### Vision Polygon

To create a Polygon:

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

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

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

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

- Target Selection Method - From the Live View, click two points on the first edge, and then one click on all the other sides to define the feature. Ensure that you have set the Number Of Sides parameter first. This establishes the polygon'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 polygon into the Auto Feature dialog box. The hit targets will automatically be displayed for the polygon.

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

6. Click Test to test polygon measurement.

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

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