PC-DMIS giving bad results

Need help!! Not sure why PC-DMIS keeps giving me bad results. I have created different alignments, different hits, different workplanes and views but PC-DMIS still gives me wrong numbers. Any suggestions on what is going on?

On the blueprint I have provided the Dimensions I need and the results I am getting.
I am currently running on PC DMIS 2021.1
CMM SF 7.10.7

  • Your cylinder 3 actuals are concerning. The deviations are quite high. Something looks to be off between your rotational line1 and the cylinder3 centerline. Throw some more dimensions in there and do some more manual checks to narrow down the disagreement between your two methods. ie. angle between cylinder 3 and your planes, angle&position between cylinder3 and line1, distances of the pierce points to the holes&line1.

    Since your final result is a 2d distance, chances of error tying back to how the part is aligned is high. I would also measure the cylinder3, level and align to it, then remeasure it to be certain no vector issues if your 2 holes and planes happen to be off.
