Hi Matthew,

I guess it would be possible for me to detect when you've got a surface where each edge is only touching one other edge (unlike say a box as mentioned previously), and then make those into a closed loop in the AI file same as a joined curve.

That would then make the same kinds of results between exporting a planar surface or the original curves.

I've made a note to look into adjusting the AI export in v3 to do that.
