True position capability

This may have been asked but a search netted me nothing. Is there a check box or something that I can modify that will correctly calculate the Cp and Cpk on a true position call out or other one sided call out. I hate that a hole with 3.0mm true position tolerance and an average measured TP of .3 gives me a bad Cpk.

  • Yup, My boss from 12 years ago taught me about the box in a circle thing. Although I always used (TP*.7071)/2. Your way is faster. Thanks for the help Matt.

    While you point about directionality makes it moot in this case, any idea why there isn't a unilateral option in DataPage like there is in MiniTab? Not too many things I measure use a true Unilateral tolerance but I am just curious.
