Sorry, this just rubs me the wrong way. Maybe it's because I'm an Architecture student. First, you said "cheap," implying that the product is substandard. I'm guessing you meant more along the lines of "inexpensive," which is only half true. The "free" version isn't as featured as the Pro version, which runs $500 USD. Secondly, SketchUp is Business Information Modeling (BIM) Software, and about the only thing it really has in common with 3dsMax is the "3d" part. In truth, it's much closer to Revit. In fact, SketchUp files import seamlessly with Revit. Anyway, it's a really promising emerging software in both the architectural and engineering fields.

I'll go hide in my castle before the villagers come after me with pitchforks and torches.
