Rotation Animation (College Work)

Cogs are the most common rotational item, so it is very nice to animate and show that it works. I made sure that the cogs were well separated and work just as well as normal cogs do. 

How I made the Cogs was using the already built in cog splines and changed the spokes on them so that they would fit together perfectly. Then placed the Extrude Nurb on the splines to make them full and stable.
