I have a small part with a through hole too small to probe (Ø.052 of attached dwg), so I put a pin gage in the hole and measure the pin. I've done this a couple of times by modifying the CAD data from an inner diameter to an outer, and changing the length of the feature to match the length of the pin. The hole has a positional callout with MMC. When I put MMC in CMM-M it calculates the bonus opposite of what i want, giving me too much bonus, but it obviously makes sense.

So two questions.

1. Is what i'm doing modifying the CAD data a good idea/bad idea?

2. Can I/should I change my modifier from MMC to LMC to get my desired bonus. I tried it and it seemed to work.
