there is the hard way, or you can use illustrator format.
Note that if you use too new a version of Illustrator, it doesn’t work. You get:
// Error: Command illustratorCurves failed. Open Script Editor for details.
Just save it as ILLUSTRATOR 3 and it will definitely work. FILE / SAVE AS .. (pick a name), THEN another dialog appears with a dropdown.
In Maya 2009, you can use up to ILLUSTRATOR 8 format, but ILLUSTRATOR 9 doesn’t work (for me anyway).
