Bluetone is right about importing Adobe Illustrator AI files. In Spline modeling you would simply select a plane that you want the AI file on and do a File Import. TJ is also right, in that CorelDraw will also export to AI. Now down to the question that started all this. Carrara can NOT make models of 2d illustrations. It can only extrude them on planes, like cross-section of a aircraft. You will still have to put a lot of time and effort into creating models --Ashley3D
