It certainly is a different approach to modeling then I'm used to. BUT it's one of the easiest 3D apps I've ever used. Just not very familiar with some of the technical terms when it comes to NURBS or CAD.

In the 2D world I've tried CorelDraw, Inkscape & Illustrator but found vectors too confusing. But oddly I find your NURBS app very easy to move around in. And surprisingly very quick to get something visualized.
