I have a project which is an existing building we are renovating. I phased the building as needed.
To see walls through roof, I use the "Underlay" method. However, when I attach the wall to the structure above, the wall disappears from my roof plan. The weird thing is, it only happens to some of them. If the wall is not attached, it does show up. Now, this only happens when the Underlay Orientation is "Look Down". When I "look up", my existing exterior walls don't show up at all but the new exterior walls do. What am I doing wrong or what have I overlooked? Or glitch?

Are the walls Top Constraint Connected or Unconnected. Try Connected.

Thanks for the quick response. This does work but I have different roof heights - sloped asphalt roof. When I change the range and it goes above the lower roof, you can only see the top of roof for those areas.
I've changed the view depth to to -50' and I still cannot see the lower walls through the roof. I can see roof, but not walls. The highest point on my building is 24'-0" (peak of roof).
My settings are:
Top (bearing level = 12'): 32'
Cut Plane: (bearing level = 12'): 30'
Bottom: 23' (above 1st floor) (above the highest wall - 22'-10)
Depth: (level below 1st floor): -50' and switched to unlimited and no joy.
You may try to use Plan regions on the lower roof areas and play with their view range.
Can you share the file?
What's your View Phase Filter setting? Try "None".
@Anonymous , can't you just attach the RVT?
