In this turtorial, Rich explores the tool bar some more and how to move, push/pull, rotate and follow me.
The follow me tool's quirks are similar to equivalent tools in other 3D programs out there. Usually with the programs I'm used to using; one creates a profile (e.g. crown molding) that is perpendicular to a path/rail(s) to extrude (Push-Pull) a resulting solid. What I'm saying is don't give up on the tool right away if you don't get the result you expected on the first try. Learn how it works, and you can create some edge treatments you never knew were possible.
