Making walls display Halftone

[olyconstruction 1]

Hi Chiefs,

 

Is there a way to make walls display as halftone on a particular layer set?

 

I have a roof plan and I want the layers beneath to display in gray, or without a fill, but I do not want it to affect other layer sets where the walls are supposed to be normal. Does anyone out there have any Ideas about what I could do??

 

The first attachment is what I am looking for and the second is what I have.

 

Thank you for your help!
