Wall fill types & patterns not changing

[CRE8TIVE]

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!

Make sure the wall you drew is using the wall type you changed.  Make sure the "walls, layers" is turned on.  Make sure the wall is not a "railing".  Could be something else, but would probably need to have a plan to look at.

 

As far as other ways to make some walls look different, could also use the wall hatch tool.

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