AutoStudio. I worked an an Alias rep for about 2 years before moving over to my present job. The question of if they actually use it is a different thing. What happens with AutoStudio is that they design the car on paper, build the car in AutoStudio, then export the models to Unigraphics, or Pro/E for production. The curve creation in AutoStudio blows the the competition out of the water, but that same competition has the ability to talk directly to the manufacturing process, while AutoStudio does not.
