  • Thank you all for your replies. Here's my problem.... without being able to post a pic due to strict ITAR rules I will try to explain as best I can.


    Imagine a cube. Top plane being Dat A, +X plane being Dat B and +Y plane being Dat C. There are four holes on each of the 4 X (+/-) X and Y planes. DRF for the +X and -X are BAC. DRF for the +Y and -Y are CAB. Being in the correct alignment prior to measuring holes I am finding everything in on say Datum C but OOT of the plane opposite (-Y plane). Same for Datum B and its opposite (-X). Now I am using Geo Tol to report my finings. Another company machines this part and I am checking their work. I ran through their report and for the most part they are using Geo Tol to report as well until I get to the holes in question. They then switch to Legacy which shows the holes in tol. Now because the report doesn't show the DRF there is no way to tell what alignment they are in when checking said holes (ie ABC, BAC, CAB, ACB etc..).

    Side note... I come into PC-DMIS world this year with 20+ years experience, most of which using Calypso and last 6 years using Modus + others LK camio etc..
