Wall Coping and Parapet Walls

I’m working on a building that has parapet walls that butt against the roof in certain locations. However, interior walls that intersect with this parapet wall will cope with the wall all the way up to the top of it, not stopping at the roof. Is there a way to work around this behaviour?

Hi @jsb.walker I’m not sure to understand this issue. Could you provide more screenshots of the error or how would you expect the walls behave, and the related 3dm file?
Thanks!
