Number one thing:

NEVER MAKE A FABRICATOR DO MATH! This is the number one frustration and mistake/part scrapping thing I see on all drawings.

Give dimensions that you can actually measure not goofy BS like through a solid part that you can't put a tape through.

Correct tolerances. Does a weldment really need to be +/-.005? This kind of stuff wastes so much time, especially on poorly engineered stainless sheet parts.

Designing things that are impossible to do well without an inordinate amount of pre/post-processing.

Design parts where you can get your. MIG gun or TIG torch into whatever it is that needs to be welded.

Learn to bolt/rivet/spotweld/epoxy stuff together if you want fast throughput with minimal distortion.

I could probably rant for hours about this.

I agree fully. There is a disconnect between design and the floor. Proper tolerance being the tip of the iceberg.

I think it may stem from the perspective of the screen to real life?

Thank you very much for your response. It was exactly what I was looking for. Rant away!

Cheers!

Too many engineers have never done enough or just even barely any work in meatspace. It shows. New cars are a prime example of too much CFD and FEA. Working on them requires too many specialized BS, and they aren't sustainable. (Don't get me started on thy asinine regulations, either, but that's another matter all together.)
