Simultaneous datum shift on profiles

[[Da...]]

I have a print set up for hard gaging that has multiple profiles that reference the same B datum with the MMC modifier in the datum section of the feature control frame (allowing for datum shift with departure from MMC).  The tolerances are tight for the material and I'm trying to figure out if there's a way to simultaneously evaluate the profiles with the directional datum shift.  More background to explain without sharing the print (ITAR, CUI), two opposing profiles share the same B datum which is a hole through the middle of the part lets say,  so if one shifts in one direction the other must follow that same direction.  Without it being a hole and using the best fit bore pattern I'm not aware of a solution, I also don't have PCM availability currently?

Congratulations Danny.  You have made it to the boss round 🎮⚡🤯

That's an advanced evaluation.

I do think it can be accomplished in Calypso using multi-tiered alignments.  I'd recommend mapping out the hierarchy and building out the alignments in order of precedence.  You may or may not need to include a formula or two to simulate the datum shift, which you do not need the PCM addon to utilize.

Good luck and be sure to update us on your progress.

If you are using Calypso 2023 or Calypso 2024, and as long as you do not need to use Free-Form, you can do Position and Profile Simultaneous Evaluation via the new GD&T engine.

As mentioned by Richard, you can use the new GDT engine Beta in Calypso 2023 and 2024.
