Great program and very easy to use and currently free for beta vertions  , but it is very stable!!!

From MOI website about the desighner:
"Michael Gibson created Rhino when He worked for Robert McNeel.
Michael Gibson:  "Triple Squid Software Design is a single-person company. My history, very briefly, is I worked at Robert McNeel & Associates from 1993-1999, then at Microsoft 1999-2003. In 2003 I decided that the time was right to leave Microsoft and do my own company. Since then I've been working on MoI on my own."

Currently will export:(Soon to have export abilities of DXF,DMG...)

So what is the cost?

It's free for now, I belive he has planes on selling it in the future, but I'm not sure.

I think I might have posted this in the wronge topic section   

Looks interesting. Could you also post it in the links section. Thanks m8
