Can anyone tell me if there is a standard which replaces ANSI/ASME Y14.5?

Thanks

ASME Y14.5M exists and still active. You may find the standards by searching the originating organization instead of ANSI. The current version is ASME Y14.5M-1994.

jsummerfield is correct.
Curious, why would you want to replace it? Or did you hear somewhere it was replaced?

There is a new standard to supplement Y14.5. Check out ASME Y14.41-2003.
 
can anyone explain the proper use of
PROFILE when the part is dimensioned using +/-
tolerances instead of BASIC dimensions?
 
mm2c, try reposting your question in forum1103

You can NOT use +/- tolerancing with profile.
All dimensions MUST be basic for the outside profile.

We just started a GD&T training class this morning and the instructor emphasised this point.

"Fixed in the next release" should replace "Product First" as the PTC slogan.

I concur w/ looslib.
using a +/- tol you are done right there.
Stacking another tol on top of that with Profile is not an option.
