Every few years I make another major attempt to switch to CAD. After a couple of hours of total focus, working the commands : Line, rotate, fillet, mirror, snapping on and off etc., I do get into it, I look up and realize I could have drawn the thing my hand in about 15 minutes.
See my post above about needing to commit to a month of significant daily use to get productive with any new large piece of software. I did this in the '80s with AutoCAD and have enjoyed drawing much faster and better ever since.
