Roadway Designer for Beginners

I too am a newbie to the Roadway Designer tool. I have created a Horizontal Alignment and Profile and now am curious on how to use this tool to model the roadway. Does anyone have any Videos for what do do with the templates after they are made? How to use and manage the corridors? and how to make the proposed surfaces? Any thing that isn't already on the site would help especially if it was a taping from an online class.
