Automatic retrieval of Roof plane area

I am currently engaged in a solar energy potential estimation project. For this purpose, I need to retrieve the roof's surface area automatically. Is there a way to do this with CGA rules to get the surface area of the planes facing a particular direction? or at least the entire roof surface area.

Hello @richiedlon 

Thanks for the question. I hope to help you with your interesting project.

You can analyze the roof shapes with the geometry functions—ArcGIS CityEngine Resources | Documentation 

Use geometry.area() first, then calculate an efficiency factor from geometry.angle(azimuth) and geometry.angle(maxSlope).

These values can then be reported: report operation—ArcGIS CityEngine Resources | Documentation
