In Autocad, a black background for the drawing area is a choice in the "options" pulldown under "tools" on the menu line. Black is the default and you will go back to using it as it is so much easier on your eyes. The one drawback is drawing a black colored object on the black background. Autocad fixes this, when you draw with color 7. This is the default color that displays as white but prints as black. I have not used the modern Inventor but I am guessing it steals a lot from Autocad.
