3D Models in Storyline

I believe the closest Articulate can provide right now is the "add pictures as states" function.

I've mocked up an example which uses a slider to change the state of a png sequence. You do have to manually attach the trigger to each state, which is an absolute bear, but you can do some cool things. I once saw a 3D tour of a facility made of multiple layers of rendered objects set up this way, so that you could click on a tool in the room no matter the perspective.

You'll note that frame 30 pops. I'm not sure why it did that, but its a small matter relative to building the triggers.
