Whenever I switch configurations and/or go in/out of isolation, sketches and planes become shown when they were previously hidden. There doesn't seem to be any rhyme or reason to when or how this happens. This would not be a big problem if I had a couple but the assembly I'm working on has hundreds and hiding them all the time is becoming annoying… not to mention the productivity hit. Is there a setting or switch I'm missing (besides the easy button)?
I believe you can hide planes and sketches globally with the view pull down menu. view>planes, and view>sketches to turn them off no matter what their state is.
