To create a Polygon:
Select DCC Mode 
if you want to create
and measure polygons in DCC mode and your machine supports DCC motion.
Select Auto Polygon
from the Auto Feature toolbar (Insert
| Feature | Auto | Polygon). This opens the Auto
Feature dialog box for the Polygon Auto feature.
Vision Polygon Auto Feature dialog box
From the Auto Feature dialog box, select a polygon in one of two ways:
CAD Selection Method - From the CAD tab, click once near the edge of the polygon on the CAD surface to establish the polygon's location.
Target Selection Method - To use this method to select a polygon, follow these steps:
In the Feature Properties area of the dialog box, type or use the up and down arrows to set the value in the Num Sides box.
From the Graphic Display area, select the Vision tab to display the Live View window.
Click two points on the first edge, and then click once on all the other sides to define the feature. The total number of sides should correspond with the value in the Num Sides box you set in the first step.
Adjust the lighting and magnification as needed.
Click as close as possible to the CAD element to ensure PC-DMIS does not choose an incorrect element.
PC-DMIS Vision automatically places the nominal data for the polygon into the Auto Feature dialog box. The hit targets are automatically displayed for the polygon.
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.
Click Test to test the polygon measurement.
Click Create on the Auto Feature dialog box to add the polygon to the measurement routine.
Save the measurement routine for future execution. See "A Note on Executing a Vision Measurement Routine".
