I found the following instructions (at https://www.gamasutra.com/features/20...graber_pfv.htm):

"Import into Maya

Use the following as a guide to import your Illustrator files into Maya:

In Maya, use meters (depending on your project, this may change).
Select “Import Options” and choose Illustrator as the file type.
Use this magic number as a scale factor -- 25401.9"

Hope this helps
