I use a lot of planes and C/L when constructing CAD models and I tend to leave them in case I modify parts using them. When these parts become subassemblies and then general assemblies with perhaps hunderdes of parts the views get quite messy and if I want to do a GA drawing I have hundreds to hide. Is there a way to globally turn off "hide" all the planes C/L s without having to do it one by one from the model, drawing or structure tree ?
