I can't read the yellow lines and text against the white background on my monitor. I've searched and the question is probably too basic for the help files !!! I need to set the screen's background to black; how is that done??? There has to be a simple answer to this; I've done it years ago but can't find it in my ACA2009 software settings...
I generally use Revit so I have forgotten some of the setup nuances. Help is greatly apprecated.
