Well, I tried using the PDF export, and then importing it into Inkscape (which for the record, I hate lol)... and the results are quite painful.

It breaks up all of the shapes into separate lines - a square would be 4, and with rounded corners it'd be 8... plus then the solids/fills are a giant sheet in the background, as opposed to the actual shapes...

It's a mess LOL

I LOVE Moi3d. It's always been my go-to program for any 2d or 3d design. But the 2d exports are quite painful :(
