Another ASME profile question Ugh!

I know this gives people brain aneurisms as it does for me, so I'm just asking for opinions. I've looked at numerous threads on this to the point my head is going to explode. I have a blueprint that says, "Blueprint interpretation, ASME Y14.100" in the notes. Underneath that it says, "Dimensioning and tolerancing: ASME Y14.5".

I thought in ISO you doubled the worst points deviation. But my AMSE 14.5 is doubling it in GEOTOL. What is correct these days? Double it or just min-max? By the way I
'm running 2020 R2. Was this changed in later version?

  • In PC-DMIS 2018, using FCF dimensions, ASME. (Just an exaggerated example here) if deviations range from plus 11.001mm to plus 11.010mm, PC DMIS reports the profile as 11.010, rather than 22.020. That's wrong, and always was wrong.

    In the case of that particular software version, switching to ISO, reported values are now 22.020. That's right, and always was right. (edited for typos)

  • , it does, with this particular version, turn red or green appropriately, but that does put the user in a position of perpetually explaining why you reject parts with seemingly acceptable "Meas" fields. The other issue is that this changed in version 2021 or so. It PC-DMIS was right between the years 2009 and 2021 why the sudden software change?
