I have a building that I want to hightlight from the other builidings around it. The buildings were designed using Arch. 2012 using their respective layers, in my AutoCAD drawing I x refed in the surrounding building models with the idea of changing all the layers to a single layer that has been screened down to 35. The layer properties say/show all the layers within the x ref are on my screened layer but the colors within the drawing did not change therefore not plotting lighter than the building I'm trying to highlight. I've also created a new layer called "x ref" to use when I x ref the building model in. Neither has given me the result I'm looking for.

Am I missing something else? TIA.
