Profile Tolerance per Y14.45 2021

Reporting A Unequal Surface Profile Tolerance per Y14.45 2021 in PC-dmis we not sure if the results are correct versus the calculation in the measurement standard.
In PC-dims it reports the profile as being out of tolerance by .006
the point that deviate's the most are in the positive direction by .008 PC-dims seems to double that deviation.
I believe that .008 would be the G X 2 = .016 + .01 = .026 OOT by .016
The same calculation seems to work for a Equal tolerance zone or you could double the .008 for .016 as your Profile
see attachment for the CMM results and the outside the tolerance results.

Is it PC-DMIS?
There is no attachment.

For engineering or to diagnose a fit problem, Y14.45 gives zero or even negative useful information, so I have a blind-spot.

If you add the attachment I can try to compare it to the Y14.45 method.
 
I keep getting a error when attaching a file with the problem+

Oops! We ran into some problems.
 
What file type is being attached and can you just use the image button instead?
 
When you use the image button what happens? (also available by ctrl-P) Do you have javascript disabled?

I may be on our end we keep getting the same error

Do you have javascript disabled:

YES [_] - If yes, then enable javascript

NO [_] - hmmm.

What browser? What OS? Perhaps move the file to a local folder?

Did you use ctrl-p? Did "drop image" appear?

Are you trying "Attach files" instead of Insert Image?

3D Dave I tried it from home it works have to see what's going on with the work computer
