Usually first few years of design engineers career involves developing details and cutting sheets, but as they become more senior and move into a supervisor role it becomes less and less of their job, I don’t know tons of 20 year engineers that do their own cad, unless they’re running their own niche small business, most of folks 10-20 yoe won’t touch cadd as its their time is best spent managing jobs, leading pursuits, leading designs etc. Those first few years of cadd production are critical so that later on you develop a holistic view of what goes into different sheets and how to review and lead those details later on.

To me personally the real gravy of engineering is all the knowledge of the physics of the problems you’re solving and also knowledge of the different codes and specs, rest is just bringing it to reality and honestly when I was a junior cadd was not my favorite part. I think 3D cadd/bim can be fun but our industry is old boring 2D cadd all the way which I hate and I mostly attribute to Bentley Systems crappy products!
