I don't really keep up with technical 2D vector programs. I have used AutoCad since version 10, so there is no need for me to give up the industry standard, but it would be cool to see what this does. The 3D modeller Rhino was loosely speaking spawned from AutoCad. Though they are separate companies. Speaking just as loosely, a free program I mentioned not to long ago was spawned by an early programmer who worked on Rhino. Here is the post... Moi.
