I have been using animation on CATIA for more that 10 years. I started working on Inventor Publisher 4 month back. One of the main problem through Inventor Publisher is the triad. It's hell to reorient the triad, i'm asking, till now Autodesk still insists on using the same old way for using the compass "triad". In CATIA, it's so easy to move the triad, put it on the object you want to move, not only that, but on the geometry you want to, the triad will compute what kind of the geometry you are on, and it's ready for manipulation. I advise the Inventor publisher developper to go through CATIA and see how it works with triad, and to have that advantage in Puplisher and inventor soon.
