Is there a way to use a referenced drawing in black & white only?
I want to bring in the architect's backgrounds into my drawings as a reference, then annotate viewports with my own information (position of light fixtures etc.).
To make my own drawings clearer, I want to set the architectural drawings to black and white only, then annotate them with my information (position and shape of light fixtures & circuit references) in a colour, so that this information stands out on screen (but still gives me the option to print everything in black & white)
However, if I set a viewport to black and white (in the Advanced settings), then all annotations are automatically black and white, too. If I go back to the referenced drawing, and set the document preferences to black & white, then this seems to affect the on-screen display of that file only, as when I then reference or update the drawing into my file, all of the class/layer colour information faithfully returns & I am back to where I started.
This is maddening me; surely there must be a simple way to display the referenced drawing in black and white, without manually editing the architect's file to set all layers & classes to black and white & I am just missing it?
