I absolutely loved autocad for this. One hand on the keyboard, one on the mouse is an easy way to double your productivity. The speed at which you could draw things was amazing. I had a custom alias file with most commonly used shortcuts and the enter key was bound to right click which removed the need to move your left hand over the keyboard. This was in the 2000. Sadly the more recent versions I have tried make this harder to do. If I hadn’t switched career I’d still be using autocad 2000 !
