We've been pushing along with our latest release of Smart World Professional, and we've got some elegant tools coming online that will showcase why we went the route we did. One of the biggest requests from the AEC industry is Shadow/Solar analysis. There are tons of tools that do this, but they can be expensive, hard to use and even hard to get data for. That's why I really like the Mapbox Unity SDK and its 3D buildings.
You can, of course, load your own buildings into Smart World Professional but this is a great way to see how your projects will impact the surrounding city out of the box with our tools. The Unity SDK really shines with this kind of work.
