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?

  • Safest way would be to collect T values of a bunch of points, but "OUTPUT=NONE" in the characteristics, then maybe use variables to force PC-DMIS to calculate profile correctly (2x the maximum absolute deviation of all the T values).

    If you use FCF dimensions, you will be opening yourself up for a world of grief, because the reported values will be different (and usually wrong) with nearly every version of PC-DMIS.
  • I'm not one to push buttons on pcdmis and hope I'm getting the right figures. I like to know how stuff works. With that said I've created my own alignments, reported out the deviations then ran the Geotol FCF and both came out with the same deviation. It seems to work fine for my needs. Kai, I'm not sure what problems you are having or how you can explain them better to Neil.
