True Position in 3 axis???

Ok, I have read the post regarding this so called argument that my boss and I got into today. He told me that you cannot measure true position in 3 axis, as I told him he was wrong. I know it depends on the way the FCF calls it out, but I tried to explain to him that it is possible to measure TP in 3 axis.
I have seen the formulas, so I know it's possible. I just wish I could get one of you gurus to reply back explaining that it is possible and why. I see the picture but he does not. I do not like to get into pissing matches with upper management, but I have learned a h**ll of alot from you guys, and I know this is possible. So if one of you fine gentleman can back me up on this, I would very much appreciate it. Thank you very much.
Now I am going to get a cold beer.

I have seen 3d true position (spherical) on a few sheet metal drawings for GM.

Just wanted to say that even IF a feature HAS three Basic Dims to it but is called out as a diametric TP (Two Axis) then I report it as two axis and use the third axis as incomplete or BASIC NO FCF. Usually it is obvious which Datum Axis is insignificant. Sometimes not. But, call me cantankerous if you want, I give them what they ask for and don't care much for second guessing Engineers.
