hey matt
I worked with all the tutorials and the examples given in the web site of ESRI, besides the example of redlands training.
i'm now a GIS studant, i have projet is to design a new smart city with city engine,i found that the redlands example is the best example to start with, i started before understanding the rules of the example.
the rules that i understand are ( environment reporting, environment setting , zoning , photovoltaic roof....etc)
and i tried to understand the other rules ( building facades , building construction , tree and building street ) but it's a difficult without comments.
