I'm using Autodesk Building Systems 2007 without service packs. My goal is to xref an architectural floor plan as an overlay and display it grayscaled behind my HVAC drawing. The architecural drawings we receive do not have a "screened" configuration available and don't respond when I copy in a screened configuration. The check box that locks the xref's default display configuration is not checked.
There must be an easy way to make grayscaled backgrounds?
