Revit Arc 2013. Which setting is wrong, because the objects are visible through the building. Win 7 and the video card Nvidia Quatro 2000.
You can set the transparency in View>Graphic Display Options.
That looks great.
There seems to be an epidemic of misunderstanding about what
a video card does for Revit. But all it does is convert 2D to 3D, in
addition to lighting up your screen. Almost any video card is fine.
