Just noticed this post...
I have SolidWorks not AutoCad. From what I've seen, SolidWorks is much easier to use than AutoCad, but there was still an initial learning curve that was frustrating and difficult (for me). I still have much to learn, but once I got over the initial pain, things have progressed rapidly.
And it is not pirated, though I'm not sure if the details of ownership transfer EULA wording may have been technically violated. Those darn things are so complicated you'd need to hire a lawyer to be sure, and like most people, I don't actually read them. I work in the computer industry, and a friend works for a company that uses SolidWorks for modeling. They upgraded from 2001 to the new version (2003?) and had older versions unused. Their person in charge of such things offered him a legit copy of the now obsolete SolidWorks. He didn't need it and new that I would be interested, so he passed it on to me...
