Thanks, Otis I would not want jumps, but smooth rotation and without an end. I think that your suggestion of a loop will always have to end after a certain total angle.
I agree that it seems there is not a spinSelected solution. However, the doc says rotateSelected takes all the same arguments as rotate, and rotate doc includes the spin argument. Also, spin is said to share all options with rotate. This does not seem to be the case with "selected" or "branch". I am now also testing an alternative with multi-model loading and basic rotateSelected applied to each frame separately, which gives me the "stepped" rotation and be made indefinite using "anim on". Not the best solution, but might be the only one. (By the way, Jaim, this exploration is for your case we were discussing today) ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
