Thanks Jeff
I have never used ProxyGraphics before and now we do a lot of work between Revit and ACAD. We have to turn on ProxyGraphics in ACAD to see the AEC objets in Revit. Something years ago scared me away from ProxyGraphics but not sure what. After reading more about it, it seems harmless but had to ask the question to calm my nerves before I make it a standard.
Thanks again
