X1 Change Wall Color for One Wall?

[Athenian_CAD]

Zowie - As a relatively new user to Chief, I found changing the color of one wall to be rather simple and intuitive, I'm not sure where you're experiencing the problem? I think you should be able to use the Break Wall tool on either side of the wall you want to have changed (the shared one you mentioned with the living room and dining room). Right click on that wall, Open Object, go to the Materials Tab, click on Interior Wall Surface, and if its a color you've already used in the plan, just click on Plan Material and chose it. Viola, wall changed in color. Are you still having the problem or have the other folks here gotten you taken care of?
