It would be a great added workflow to be able to export all animations (a presentation file, an inventor studio animation, a dynamic simulation) to an FBX format.
The FBX you then could use in Showcase or Max to focus on the added value of those software packages instead of recreating those animations (try to recreate a dynamic simulation in Max, it'll never be as good as you can in Inventor). So adding an environment, adding materials like sand or water and other effects like the sparks of welding.
An example would be this dynamic simulation - Inventor studio rendering: http://a360.co/121481d
