Not sure how to do some kind of animation?

[thebravoman]

I would like to slowly rotate and object. Is there a place in the documentation that I am missing that shows how?

Unfortunately there is no built-in support for animations in JSModeler, but of course you can set the transformation for the generated three.js objects in your render loop.

See this fiddle for example:
