Hi everyone.
I'm looking for a workflow to import closed Polylines in AutoCAD as shapes in CityEngine.
I found this video, in which shapes from Sketchup are imported into CityEngine using the KMZ format. When I try to do the same thing, the shapes come in as highly triangulated models. When I use 'Convert Models to Shapes' they merge together.
Has anyone found a clean way to do this?
