I have a scan that is made up of six segments. Each individual segment is within a profile tolerance, but when I create a feature set of the six, the min value is out. How is the calculation different when it is a set? I figured it would just take the max/min worst of the six segments and report that. Does it add them somehow?
If your DRF does not fully constrain all 6 DOF, then each segment will be best fit differently. So when you grab all 6 segments and create a feature set, that feature set will be best fit differently than any of the segments measured individually.
If your DRF fully constrains all 6 DOF, then it would behave as you expect- where your measured lowest value of the set would be the lowest value from all 6 segments, and the highest value from the set would be the highest value from all 6 segments.
