Anyone know why recessed lights in Gypsum board ceilings cannot be copied or arrayed but if the ceiling is changed to generic, they can? This tripped me up today.
I am encountering the same problem in Revit 2014 Update Release 2. Don't know the answer, but found a workaround on the web (from Revit 2013): Change the ceiling type, copy your lights, then change the ceiling type back to gyp board.
