I found a video link (below) that explains the process of creating a terrain from a corridor. However, what used to happen with the click of the Create Surface button in SS2 now takes an eight minute video to explain. I thought one of the advantages to using SS3 is that everything would be dynamically linked so that when one part of a design changes the effects woudl trickle through. This seems like a lot more steps are necessary now to accomplish what could be done before with a single mouse click, and the results are no more dynamically linked in SS3 than they were in SS2.
Am I missing something?
