[Ja...] Posted May 28 Share Posted May 28 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? Link to comment Share on other sites More sharing options...
[Du...] Posted May 28 Share Posted May 28 I could be wrong, but i would think it would be a pattern of all 6 centerlines of the .500 width Link to comment Share on other sites More sharing options...
[Ri...] Posted May 28 Share Posted May 28 In the ISO world you explicitly have to invoke a pattern with the CZ notation. 1 Link to comment Share on other sites More sharing options...
[Ja...] Posted May 28 Author Share Posted May 28 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. 2 Link to comment Share on other sites More sharing options...
[Iv...] Posted May 28 Share Posted May 28 Per ASME, it would mean the pattern of the 6x 0.500 widths. See the screenshot below from the ASME standard. Link to comment Share on other sites More sharing options...
[Iv...] Posted May 28 Share Posted May 28 Please sign in to view this username. 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. Link to comment Share on other sites More sharing options...
[Je...] Posted May 29 Share Posted May 29 I would bet that print is ASME, because the decimalseparators are points, not a commas. Link to comment Share on other sites More sharing options...
