Roundabout In Sketchup

I found this video of how to create a roundabout in Google Sketchup.  Pretty interesting approach.  While we were first playing around with Sketchup here we used a design from microstation to create a 3d model of a roundabout.  This video shows how one would be created from scratch in sketchup.  One of the best things I learned from this video is the "follow me" tool.  Watch as the rolled curb is created and how the follow me tool makes this so easy.
