Surface Profile All-Around

#1
Hello all,
A large part of my Job is reviewing AS9102 reports for Circuit Boards. Many of our prints are GD&T. We see surface profile all-around a lot on orders. My understanding is that when SP all around is called out, the Feature Control Frame is ballooned once, and the features making up the profile are not ballooned, but are on the CMM report for verification. A range is given of the deviation from nominal.

Now one of our customers wants all features ballooned, saying we "missed" dimenions and the drawing is incomplete.

Is there a standard on how this is reported, or at least a best practice?

I have run into this a few times over the years. Usually it is from people who don't understand GDT, and are just checking a box (are all the features numbered, are they all reported).
Best way to deal with this in my experience, is to number all the features, report them out (once); if they are basic dimensions, then they get reported out as exactly what the print says.
