Other posts talking about the difficulty of painting support / non-support regions inside an enclosed model mention Section View, and I’ve seen some complaints about not being able to get the desired cutaway view. That’s not my problem - I definitely can get the cutaway I want in Section view.
It looks to me like I can paint colors / filament types in Section View, but I can’t do other kinds of painting (such as supports). Is it possible to paint supports in Section View?
