This is another one of those workarounds that I've been doing for a while and wasn't aware that a lot of people didn't know of it. Its a very quick method to creating depth in your elevations/sections without adding masses, using the linework tool, or utilising shadows. (although in Revit 2010, with directx turned on printing of views with shadows has improved exponentially!).
