Hi Luke,
The Animation workspace is for exploded views as well as any other manual animated sequence. The caveat with joints is that we are still working on supporting *existing* joints applied to a model in the Model workspace. The Animations workspace gives all the tools to manually animate just about any sequence you want (whether it be assembly, disassembly, animation of internal workings of a component, etc.).
The help site has some helpful videos, as Prabakar mentioned, and we just finished adding an Animation module to the Fusion 360 Onboarding content that you might find helpful. You can download the PDF and datasets here if you wish to run through it.
Also, here's a cool example of an animation that a student created of their Fusion 360 dataset just recently. If you open the interactive view of the model in the gallery, you can play-back the short animation. Hopefully this gives you an idea of the things that are possible today.
To answer your question about what has been added, in the latest release, we added in the ability to publish out videos locally - which was the top customer request right after we launched the Animations workspace. We also added in some other usability enhancements, such as gestura support, etc. to improve the experience. Again, we are continuing to work on adding additional functionality to the workspace, and the team is currently focusing on the support of joints from the modeling workspace.
Thanks for the feedback, and please let us know if there are any other suggestions you have as you dive deeper into the Animations workspace of Fusion 360.
Best,
Timera
