Hi all. I've been hanging around PM for a while, but brand new to the CAD forum. I have a chance to take a CAD course. An interest in drafting, a want to use it in my hobbies, and maybe even an eventual career change are the biggest reasons. But, I have questions I hope some here would answer. What minimum computer should I have available to me at home? Are there books I can read before the course started? I have zero experience. I've found some videos on you tube, but everything I saw so far seems to assume at least a little knowledge. Am I jumping the gun? Should I try to do some reading, and get a little practice on my own from the free demos I see on the internet, and take the course the next time it comes around? Thanks for any advice you have.
