Hello,

I have shapes that consist of numerous faces. Originally, the shapes were created as Multipatches when Polygon-Features were draped over an elevation servace. I want seperate the shapes in two geometric objects using CGA in CityEngine:

  1. Along the outer edges of the shape: extruded cuboids
  2. Inner area: extruded area

I tried different approaches (comp, offset, ..), but I coud not figure out how to derrive only the outer edges of the entire shape, instead of the edge of every single face of my shapes...

Thank you very much in advance for advice!

BR, Korbi
