[Ri...] Posted December 2, 2020 Share Posted December 2, 2020 I remember someone had once posted the extremely complex formulas for calculating Datum Shift (especially with multiple Datums). Does anyone remember this, and have access to it? I cannot seem to find it.

[Jo...] Posted December 3, 2020 Share Posted December 3, 2020 All I can hear is"datum shift is not bonus" lol https://www.youtube.com/watch?v=JMiNzKPVnhU Calypso will calculate if everything is in the same plane ? I don't have many prints that utilize it. I wonder if there is a way to simulate it by using the features as a pattern and reporting the profile of the Datum back to them as a Pass/Fail ?

[Ri...] Posted December 3, 2020 Author Share Posted December 3, 2020 Very true, it is not bonus tolerance. There was someone on the forum who had posted the math, and it was intense (if I'm remember correctly). I just cannot seem to locate it. I'm not certain - would be nice to have a long discussion with advanced CMM users, and GD&T gurus to either figure out a solid workaround or put the pressure on Zeiss.
