I downloaded this for my mac, finally a cad program that works for a mac!!! I found it really good. Quite simple to learn with all the youtube vids and such. Only issue I ran into was the options that didn't exist for the free version were things I think are quite useful. The ability to unfold a 3d object makes creating a part really helpful for cutting shop. There some other things that existed on the help vids but the free version lacked. If someone has a way around this please post here as I'd love to have another go at it. I mention this as if someone was to try and design parts that they would like to manufacture ask around or even have a look at what the programs will let you do, as once you have used 1 program it can be difficult to change to another. It took me a while to learn soildworks after using autocad.
