You could try Swift3d or Vecta3d. These apps convert 3d files to .swf and you import these directly into flash. Shockwave and director is another way, but the learning curve is sharp and a visitor requires the shockwave 3d plugin. However aprt from shockwave these systems doesn't give much in the way on interactivity, usually just a spinning object. Plus if the original model is highly detailed, it's a very large file to try and download, and not everyone is lucky enough to have DSL. So at Vanishing Point we've pioneered the first use of interactive poser models, using Wirefusion a Java based system. No plugins are required just a standard browser. Heres a sample car.. http://www.vanishingpoint.biz/modelviewer.asp?filename=veepster&ProductID=57 I belive you could call the java applet easily in flash.

Pinky - you left the lens cap of your mind on again.
