You can control what to retrieve from an Adobe Illustrator file.

By setting File > Import > File Illustrator options, you can enable Alias to import the geometry as a Group of curves or as individual curves. You can also Scale the image before importing it into Alias.

When saving an Illustrator file choose File > Print Setup , set Output to File and set the Output Style to Illustrator. The output results transfer the paint and shapes information. The results of opening this file in Illustrator is a display of three objects:

• the image plane displaying the final image (image plane).
• the curves that defines the shape.
• the shapes of the model which can be individually selected and manipulated.
  TipIf you want to change the geometry of the Alias model in Illustrator, export the model as a Post Script file from Alias. Open this file in Illustrator to manipulate the polygons.
