Yep.

Even when I draft parts like this in my cnc program they won't use my drawings to make new prints.

So they want me to draft but then they never use the draft to create a draft.

How do you make 3 1/2 + 1 15/16 + 1 1/4 = 7 1/4??

That is one of the few things that actually add up on that miserable thing.

3 1/2 + 1 15/16 + 1 1/4 + hole location from edge = 7 1/4

When that happens I question the initiating person as to what his desires are and "invent" dimensions and tolerances and select materials that will allow the part to function properly.

That, is another situation. NEW parts that are being designed by YOU and (fill in the blank).

When my boss gives me a pencil sketch with no
dimensions and not drawn to scale, I don't complain.

I just get on with it!

I consider it to be annother opportunity to please him.

PLEASE HIM, huh? I bet!

All of our manufacturing drawings bear the instruction ' If in doubt ask - do not proceed without clarification'
I'd be doing plenty of asking until the lazy originator gets the point and the delays are highlighted to those who should care.

Exactly. I just got a cardboard template with a few notes on it, one switch that needs to be fitted (four times), and one screw that they want to use to fasten this thing down taped to the back. It's for a car builder that has no CAD capability. This is fine, and they pay me to make the model to machine from. They answer any questions I have promptly and they pay promptly. All is well.

But for a "professional" to do the above, or worse, what Adam has posted pictures of, is grounds for execution by humiliation.

What neither of you seems to have picked up on, is that adamshive gets crapped on for doing these things and is cut no slack when the dodgy info he gets leads to a mistake.
This is not a case of "Here, I don't have time to do this properly, please finish it up for me".
It's more like a case of "What the hell is wrong with you...you take too goddam long and you f*cked it up on top of it. It's all right here on the drawing. What the hell is wrong with you"

All of us know how to work from less than perfect information but there has to be some ground rules about the compromises needed to work this way and one of the main ones in my opinion is: "Don't piss on the guy who's trying to help".

BTW, there's a good chance the old engineer is scared stupid of the computer, and has never learned CAD.
Adamshive hints at it with remarks like how he managed to wipe the unwipeable title bar, that he doesn't know how to dimension with the dimensioning tool, and that he hand sketched on a TIFF file to get some information out to the shop floor.
He's probably defensive and obstructionist because he's scared of losing face in front of everyone from such a young pup...that's likely why he won't even use the amended CAD files he gets from adamshive.
So here's a thought for you adamshive: can you find a diplomatic way to help him out?
If you do it right you might have a friend for life, and you might get a chance to tap into the stuff he knows well and broaden your own knowledge for free...it might be worth a shot.
Hell...you might even turn the company into a good customer when you go out on your own!

Those drawings are bogus. (Not to mention the stacked tolerances on the plate)

My only tip is to grab a handful of different color highlighters choose a different color for each feature & mark up the "print" before you make a real drawing. When you draw it use the matching color per layer. Yellow= A Blue = B ect...

It's bogus, but sometimes you've got to "kolor wif da big crayonez"
