The tyAiImporter is a 3ds Max IO module which allows you to import Adobe Illustrator (.ai) files created with any version of Adobe Illustrator up to (and including) the version installed on the machine.
You must have Adobe Illustrator installed on the machine to make use of the tyAiImporter. If Adobe Illustrator cannot be found automatically, a popup will appear asking you to locate Illustrator.exe in order to complete the conversion process.
When importing an .ai file using the tyAiImporter, the import process will wait until Adobe Illustrator (if found) has been opened automatically (to convert the file) and then closed automatically (at the end of the conversion script execution). If something interrupts the automatic open-convert-then-close process (for example: a popup message in Adobe Illustrator requires user input), 3ds Max will remain unresponsive until the user intervenes and closes Adobe Illustrator. So, if 3ds Max freezes during the tyAiImporter process, check that Adobe Illustrator has closed (and if it hasn’t, close it manually).
The tyAiImporter does not modify the source .ai files during the conversion process. Instead, the converted data is saved to a temporary file and removed when the import process is completed.
