File menu > Import > Select File To Import dialog > Files Of Type > Adobe Illustrator (*.AI)
You can import Adobe Illustrator (AI88) files into Autodesk VIZ.
When importing AI88 files, the software converts polygons to shape objects. You choose an option in the Shape Import dialog to set how the shape objects are created:
Single Object—All polygons in the .ai file are converted to Bezier splines and placed inside a single composite shape object.
Multiple Objects—Each polygon in the .ai file is converted to a Bezier spline and placed inside an independent shape object.
