You nailed it! It was 'wall hatching', a tool i've never used before. Much appreciated!

Hello, I'm designing an add-on to an older home. I would like the new walls to have diagonal lines to indicate they are new. But, when I go into the 'wall types', 'define', then change the 'fill', nothing happens. The wall remains white, with no pattern. Not even colors work. Am I missing something? 

Also, is there a way to change the 'wall fill' pattern on select walls only instead of changing every wall?

Thanks!
