CAD freeware?

Thanks, all good suggestions. I downloaded Sketchup and have been playing with it. Works pretty well and I've arrived at a method that probably will never be accurate enough to produce blueprints but should do the job for my intended purpose.



Starting with a photocopy blown up as large as possible I put it against the screen and draw over it with a series of straight lines. Then use the arc and other tools to smooth out the image and fine tune until it looks as much as possible like the photocopy.
