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.
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

Sweet project. I have been inside the one in Chicago that was the only captured 1 during the war. Movies make them look like cavern.... more like a gopher hole...
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.
I was on a 20 year old sub back a long time ago and have toured a couple WWII era boats.
Biggest thing I noted were how much larger the officer's areas were at the expense of the crew cabins (they're still a *little* larger than crew areas, not to the degree I saw)
