For those in a manufacturing, engineering, or in a design environment, what are your biggest challenges?
What is something you wish you had to remedy the situation?
Just curious…

I don't know how they did it on that scale
Thinking about it they could have placed the large stones and filled in with the smaller stones as they built upward. I've looked at the wall patterns and sometimes this works but sometimes all the stones in an area are large stones only.
I think it is entirely plausible that the ancient civilizations were way more advanced than we think they were.
The ancient Egyptians have evidence of core drills that you can count the rotations as it cut through the granite. The rate of feed is calculated to at least the rate of feed for our core drilling today.
The evidence is all over the place and nobody asks the right questions.
The obvious question is: where are the tools, where are the smithies, the smelting plants needed to sustain a technology like that. Also: why is it that nowadays we do not build like this (ultra low time-preference). The lack of evidence of artefacts combined with the latter points to an issue of mind rather than one of matter. Are there forgotten ways of impacting, shaping matter in the mental capacity? Use of sound? Turning granite into a plasma temporily? Or just stone tools and millennia of ultra low time preference stamina?
Not enough competent draftsman. CAD is great and all, but a good drawing is so much more than that, especially to the guys on the shop floor.
What is lacking on the drawings that you see?
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.)
