The latest version of MoI (http://moi3d.com/) came out just the other day. One thing that was implemented was the ability to export to Illustrator format with some line output options. Pretty neat I think.
Shaded background included in this one. All vector format, except the shaded background.
All vector format.
AI Export Options
AI Export Line Style Options
Layers export as well
I do own a copy of MoI but don't get to spend too much time with it since work keeps me so busy (where I use TurboCAD and SolidWorks mostly). MoI is a great additional tool though, as it is pretty easy to create shapes there that are not nearly as easy to do in TC or SW.
