Missing Line at Roof Edge w/ Wall

[wbs69117950]

Ref. attached. This is frustrating...Why do lines not appear when they should? I tried the "Join/Unjoin Roof" tool, but that did not seem to work.

It seems that patience from above is wearing thin, which has me stressed out...so, perhaps I am not seeing this clearly...any help would be appreciated.

Thanks,

Based on your images it appears that the roof extends into the parapet at the edge without the line whereas the other roof edge is at the face of the parapet. If this is so you have two options. Edit the roof and align the problem edge with the inside face of the parapet or join the roof and parapet using join geometry.
