Vertical Exaggeration in a 3D model.

I have a 3D model created from my corridor model. It is for a bridge replacement, so I have the roadway leading up to the bridge on both sides and the bridge itself in the model. We are trying to take some views of the model for a presentation and would like to show a sidewalk under the bridge.

The problems is, the bridge doesnt raise up very high so the elevation difference isnt that noticable. We would like to try and apply some vertical exaggeration to the model if possible to more clearly show whats going on near the bridge.

Is this even possible?

I also have my existing tin files referenced into the drawing with the aerials draped over them, so hopefully those can be exaggerated as well.

Thanks.
