Bad GD&T prints

Link to print https://drive.google.com/file/d/1PPWkIpGwM39PPnNyxP7Zwe0Rr7QkaRxh/view?usp=sharing

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?

My favorite project of all time..

A local college was repairing an engine from a u-boat and they needed some gears. They had schematics from 1942 in German. We had to translate, reverse engineer, and then create new prints with modern GD&T. My family has a large connection with WW2 (specifically sinking these SOBs) so it was cool to be a part of this process

That IS a cool project.

I've been in the U-boat in Chicago too. What really impressed me was just how complicated it was on the inside, lots of complex curves and components. It is really impressive what could be made before the days of CAD and CMMs.
