GD&T Question

[[Ja...]]

In this attached snippet of a print, would datum C be the centerline of the .5 distance pictured, or would datum C be a pattern of all  6x?

I could be wrong, but i would think it would be a pattern of all 6 centerlines of the .500 width

In the ISO world you explicitly have to invoke a pattern with the CZ notation.

I believe the print is ASME. If it was ISO I would see a lot of things I am not used too. It is not actually stated on the print. I am waiting for the customers response to that question.

Per ASME, it would mean the pattern of the 6x 0.500 widths. See the screenshot below from the ASME standard.

 are you using Calypso 8.0 (2025)? If so, I believe you should be able to use the common datum feature that was added in the new GD&T engine. See screenshot below. FYI - Calypso only allows you to select cylinders or planes when using the common datum. So keep that in mind when creating your Datum C features if you plan on using the new GD&T engine. You could also program this using classic alignments, but it's more involved.

I would bet that print is ASME, because the decimalseparators are points, not a commas.
