Excellent question, Bill. Definitely shows you are an advanced user of Visualize
Animations and Configurations in Visualize have no connection with each other. I think the best way to do this is, as you described, to duplicate the animation in the Timeline and then hide/show the desired animations per each configuration. This will give you the results you're looking to achieve.
How do I "duplicate the animation in the Timeline"? (I tried CTRL-C and CTRL-V on the time line but that didn't work.)
Oh, I just tried copying the animated camera and I now have a second animation ribbon that is a copy of the original, so that was easy.
But what about animating parts? It doesn't make logical sense to duplicate a part. Unless I use configurations and suppress the original part?
Oh, I just tried clicking on a part with an existing animation, and a new animation row was created. But it did not duplicate the original animation ribbon. How do I duplicate a part animation ribbon?
