Hi Tig and Hi Gaieus,
meanwhile I try to switch my SkUp-working style to the "Layer 0" method and yes, absolute beginners will certainly use this method.
Other users (like me and certainly all of you) who have a long-standing CAD background will understand why I have given this (wrong) advice above. For example, not only for AutoCAD or Revit the "Layer 0" discussions fill hundreds of webpages as you can imagine
Luckily the layer visibility per scene worked well so far over years and luckily there was no disaster or confusion so far. I still do not know why but fortune favors fools! Anyway, I am now getting used to the here recommended method. I have already even changed my origin template
I would like to follow and learn your "Explode Group to Layers" advice (thanks for that), but unfortunately I do not understand how to do it - I do not have any experience working with the Console - unfortunately. Maybe you or another member here might post a screenshot on this method? Or maybe someone can recommend any YouTube video tutorial on this topic or maybe there is already a thread on this topic here? Any help to learn that would be great!
Finally I have a very stupid question: how do you (all) do these screenshots here to show content of any other posts on which you refer in your own answer, as Gaieus has done it above? - I am really embarrassed to ask that
