True Position with bonus on datums

[[Li...]]

Why is Calypso not allowing to use MMC on datum B and C?
I had a part that was out of spec for true position so looking at the drawing saw that I was able to get MMC on -B- and -C-
When I used each feature A, B, C, for the alignment for this specific true position callout Calypso didn't give me the option of using the drop down for B and C. They are like greyed out and can't do anything with them.

I attached a screenshot of the drawing requirements and what the true position looks like on Calypso.

.....I just don't get it.

The new GDT engine beta can allow for the application of MMB on the Datum features available in Calypso 2023 and 2024. Give it try. KB article below for details on how to activate the license for the new engine.
