Massing models in CityEngine?

What's the most efficient way to generate 3d massing models in CityEngine? I have access to lidar data and recent oblique imagery. I know I can generate volumetric buildings fairly easily but I'm looking for something with accurate massing and roof articulation (like the attached picture). Should I be trying to do this in SketchUp instead? I have several to do so I'm looking for something other than modeling them each manually.

Scott, there is a rule called Building Construction in this CityEngine example:

http://www.arcgis.com/home/item.html?id=4b928739ca7c4effa11ee29530419057

It lets you mass model using several massing options, and then has a facade designer. You can download it and adjust the design settings of the buildings and see if that will work for you. You don't need to make a bunch of models in sketchup. Just design the building footprints and use the procedural rules in CityEngine.

Chris,

That rule works pretty well. I'm using it to model existing buildings though and for some of the more unique buildings should I do the touch up work (roof articulations other than flat, hip or gable; isolated balconies; ground floor columns, etc.) in another 3d editing software. Is it possible/advisable to edit vertices in CityEngine similar to how it's done in ArcMap? Can this be done in ArcScene or ArcGIS Pro?

Yes, you can edit vertices in CityEngine.

CityEngine was designed for procedural modeling, so if you are making a unique model of a specific, real-world building, then try Maya, Rhino, 3DS, or Sketchup. And then import them into a huge city context model built using CGA rules in CityEngine.
