The Operation | Graphic Display window | CAD Equals Part menu option (or the CAD = Part button in the Alignment Utilities dialog box) links CAD data to the measured data. This option is only available after a created alignment places the part origin/orientation at the same location as the CAD origin/orientation. PC-DMIS offers the CAD EQUALS PART option in two areas (also see "CAD Equals Part" within the Alignment option). Select this option and PC-DMIS will display the measured data on top of the CAD data. It will use the CAD data to help inspect the part.
Once the CAD Equals Part option has been used on a measurement routine, the CAD Equals Part menu option will be selected.
