When I was 18 I took a drafting class. That was about a thousand years ago when drafting was still done with paper and pencil and various appliances to assure straight lines and accurate angles. The paper was about the size of a dinette table, and a motorized eraser was provided. If you started a drawing in the wrong place, you might need to erase all or most of it and start again. So you learn real quick to imagine the entire drawing before you start. That stretches your mind power until you feel like you have a balloon inside your head, expanding to hold all you can learn. I found this to be a very useful skill in my career. I would memorize all the connections to all the integrated circuits I was working with so I didn't have to look them up again. You don't get that benefit from drafting with a computer.
Old school...yes. They talked about that while I was working on the Apple.... Cut and paste.
True...it feels like a balloon in your head...not entirely comfortable but I'm happy it's not just my experience...
Oh when I start thinking I get a really bad headache which is never good feeling.
