Of course this site really doesn’t have much to do with construction, but I’ll humor you.

In machine fabrication we use 3D CAD, and for controls we draw electrical schematics, usually 2D. You can’t really design stuff without it, though in the old days we had do draft things by pencil.

What I find interesting is the number of people who find this obscure place somehow and post unrelated content, often spam and sometimes quite nasty. I usually remove the people that do it and all their comments and posts. I didn’t here because it’s at least somewhat related.

There must be money in it or people wouldn’t keep doing it.
