pc-dmis cad++ 3.7 mr1

We're cutting several parts from 3D data on several different machine tools to determine which machine cuts closest to CAD data. The cavity pocket has various 3D contours, sharp external corners, and smooth internal fillets designed to test the high-speed machining capabilities of a new machine. I can visually see some surface irregularities in some of the parts. I have two questions, if you could enlighten me.

1. What is the best way to inspect the entire part with minimal programming efforts? I was trying to do a perimeter scan but can't get it to work. Then I was going to do a patch scan. There's only 30 or 40 surfaces in the model. Is there an easy way to inspect each surface and output the points and deviation from CAD?

2. What is the best way to compare the inspection results from one part to another? I was thinking of using points to show the deviation from CAD nominal. If I inspect all 3 parts, then adjust the tolerance so that most points are within tolerance on 1 part, then I could compare the results quickly by seeing the number of red out-of-tolerance points on the other parts. Maybe there's a more precise method?

If anyone could help me with either question, I'd appreciate it.
