Bad GD&T prints

Only sharing part of the print for nondisclosure purposes, but there was a lot wrong with it. Thought I would share this since it has been so annoying for me.

They put a position dimention on many of the faces when they clearly needed/wanted a surface profile.
They also had an M modifier on almost everything including: datums that are planes, flatness, and one distance dimension

Currently talking with my contact to see if we can get this straightened out.

Anyone else deal with some bad GD&T?

I'm constantly programming parts where the part can measure good, have all finishes (like paint) applied, and be installed, but if you add a coat of paint after that the part will be "bad". It's still in the assembly, but because someone decided that edges that will sit in clearance and be painted are acceptable datums you've got CMM programmers spending, literally, 4 extra hours on a part program to apply the correct tolerances for paint. 4½ if they browse the forums while they should be doing the above.

Other than being tedious af, this company is paying way more for their parts than they need to because of these crappy callouts. And their vendors are losing personnel (like me) who don't have the patience for stupid bs. And that's just one of the many items on my list of grievances with these... be nice....
