Okay, finally got back to this and started fumbling around with InfraWorks. I have not been able to find any basic tutorials. AutoDesk's "Getting Started" guide is out of date and only a little help.
I was able to get everything I needed for the below from the national map, terrain, roads, and imagery as directed in the getting started guide but would like to change the imagery source to Bing. It looks like it has 3D building data but I'm having trouble getting it into my model. I think I might be classifying it wrong or missing a step.
Also, Matt, in your presentation you mentioned getting site piping information. How would one go about getting that information?
