Review on KOD & FORM by Patrick Ross

It's pretty easy to use, and it can be exported to other software packages like Adobe Illustrator. The interface is very basic; there are some things you have to learn by trial and error, but they do offer tutorials for beginners. I haven't used it enough yet to know how well it works with creating 3D illustrations. I'm using it primarily for 2D vector illustration, so far I've only been able to create simple shapes, but it seems like it would work with 3D models too. I haven't had any problems or difficulties while using this program. I mainly use it for creating 2D illustrations.
