Excellent 3D Drawing Tool
I first tried the demo version of Rhino and found the included tutorial easy to understand and with excellent demonstrations of Rhino's capabilities. I then tried several demo's of other 3D software and found they were no match to Rhino's ease of use and exemplary tutorial. I made a quick purchase and am even more pleased with the full learning tutorial and manual. It's the easiest to use and most intuitive 3D drawing software I have seen.
