Can we please add an option to not bring materials into a drawing like there is for annotative scales? For those of us who work with people who use Revit and we have to bring their exported model into our drawing. We have to purge the heck out of our drawings every time we bring their model in to see where our pipe or surfaces need to match up. It truly is a pain and can blow a drawing up to sometimes 6 times it's regular size.
