I'm in Revit 2009 and, when printing a residential site plan the walls and roof of my building are printing in such a light half tone they're barely visible. It's a straight up plot w/ no underlay. The walls all print fine in other views. Why would they print near invisible in only the site plan. Is there a way to adjust this. I know how to adjust half tones in later versions of Revit but can't find the setting in 2009.
