To create a Polygon:
For machines supporting DCC
motion, select DCC Mode 
if you want to create and measure polygons in DCC mode.
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.
Vision Polygon Auto Feature dialog box
With the Auto Feature dialog box open, 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 - From the Vision tab, click two points on the first edge, and then click once 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.
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 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".
