hi there,
i just found that “nesting” of proxies is not supported..
also a skatter inside a sketchup file that is loaded as proxie is not supported 
im not sure - could be right but would also be nice.. what do you guys think about this topic? ?(
Not too sure but what would be the use case? What would be the benefits over just using Skatter right away?
for skatter ok - it was just a thinking experiment if it would work or cause crashes or whatever.. there is no real use… you are right but nested proxies in general could be usefull eventually…
im just thinking here 
@bs , I’ll forward your wish to our developers.
