why doesnt pcdmiso allow hole group to be datum

pcdmisstudent
Why is this?
i seen some methods to get around it on forum. i.e.bestfit aligning to hole group and use legacy or creating a scangroup and defining that.
if i use scangroup, do i have to fcf TP on the group before assigning it as datum, and why?
how do u guys do when u have a hole group as datum?

  • , PC-Dmis does allow you to define a datum pattern, it just depends what version you are using and which dimensioning method.

    dwade is describing how it can be achieved when using legacy dimensioning. This method is generally ok, providing you don't need to apply any modifiers (MMB / LMB).
    The method you refer to (creating a scangroup - constructed feature set) is how it used to be done in older versions of PC-DMIS (prior to 2020 R2) where XactMeasure (feature control frame) reporting was being used.
    In newer versions (2020 R2 onwards) you are able to directly define your pattern of features as a datum for use with the new geometric tolerance command - as described in the help documentation here: https://docs.hexagonmi.com/pcdmis/20...rns&rhsyns=%20

    Both XactMeasure and the geometric tolerance command allow modifiers to be applied to datum patterns.
