The 3D rotation tool is excellent but it only lets you rotate 2D objects, this means my object is wafer thin.

Is there any way to add simple extrusion or depth to a symbol?

I don't really want to use any 3rd party libraries like Away3D or Papervision, this is overkill for my simple 2D game. I only want to do this creating a couple motion tweens if possible.

More Details:

Below is what my symbol looks like (just with a bit more color). The symbol does a little 3D rotation and then flies away, it's just for something like a scoreboard within the app.
