For getting my Modell organized i use the modell topology window (German: Gliederung). I can#t find it in my.sketchup.
I am not sure if that translates to “Outliner” in English version.
if so, my.sketchup is missing that feature for now.
Mind you, my.sketchup still is beta, a lot of features are still work in progress.
Yes- we’re not complete yet, and Outliner is one of the things we haven’t built. Stay tuned for future developments.
