Hello @biaozeng  Thank you for this interesting question! Here are some CGA helper functions that will give you the index of the face with the largest area:   version "2024.1" sizes = comp(f){ all : geometry.area() } indices = sortIndices(sizes) largestIndex = indices[size(indices)-1] @StartRule // Apply on a shape with multiple front faces Generate --> comp(f) { front = comp(f) { largestIndex : color(1,0,1) fa. } }   ...

Hello @Kayleigh_T  Thanks for your interesting question! As you described, a rule package (*.rpk) has assets bundled into a file. Those assets are the ones referenced in the compiled rule (*.cgb). Optionally, the source rule files (*.cga) can also be included. However, the references in the rule are relative to the CityEngine workspace. To resolve those asset file references to the bundled ones, a file named .resolvemap.xml is included in every RPK. So if you are re-using CGA code from an RPK, make sure that all assets are correctly referenced relative to your workspace first. Then create a new RPK. To facilitate the task it makes sense to create a new project in the workspace and copy the content of the RPK into the folder structure of this projects. This should correctly reference rules and assets that were residing in the original project. Files from other projects are collected in the ".ws" folder. Those file references still need to be updated. I hope this lets you successfully customize the rule package. ... View more
