I do appreciate the inputs on this. I've been watching Chad's work on the [link=http://www.rcuniverse.com/forum/m_7335038/tm.htm]1/6 Scale F4U Corsair Group Build[/link] and thinking to myself that I need to learn to do this. I'm very computer literate, but my impression is that Autocad is pretty expensive and that the learning curve is pretty steep for casual/occasional users. So I'm very interested to hear what alternatives are out there to apply to the hobby.
