Hole pattern position to a plane only

I'm using Geotol in version 2020 R1.

If you are running 2020 R1 then you are using XactMeasure, not Geotol. Geometric Tolerance comamnds ("Geotol") were introduced in 2020 R2.

XactMeasure was more limited than the Geometric Tolerance command but it was still possible to measure the hole patterns shown in your screenshots. For the pattern of 4 holes to datum A that is shown in your first post, you need to measure datum A as a plane and define it (datum definition command), then measure the four holes as cylinders. Create a constructed set from the 4 cylinders and then use XactMeasure to report position of the set at MMC to datum A - you will notice that the results show both the position of the set and of each of the 4 cylinders.

Add another datum definition command defining the set as datum B.

For the other set of 4 holes to ABC (shown in post #4), you need to measure a plane on the datum C face and add it's datum definition. You can then measure the 4 holes as cylinders, construct a new set from them and report position of the set at MMC to datums A, B & C using XactMeasure.

One thing I did notice that you will not be able to report though, is the 3 segment composite profile of a surface for datum C - XactMeasure only supports 2 segments for composite call-outs.

Thank you kind sir for entertaining my questions.
