change wall below roof

[Jambruins]

Attached is my plan.

 

I am using the lower wall type if split by butting roof but my wall either shows all siding or all drywall.

 

How do I get the exposed upper part to be siding and the lower part of the wall to be drywall?

 

Thanks for the help.

Go up to the attic level and simply delete your manually modified attic wall.  As soon as the wall below regenerates the wall you should be good to go.
