Help! "Hole" in wall

Help!

As you can see in the attachment, a part of the wall seems to appear as invisible. As you can also see, this is actually one continuous wall. This has been a continous issue for me in this modeling exercise. I have been using the "trim to roof" tool on the walls, and I guess the issue is related to this function, but I dont understand what exactly is wrong or how to fix the issue.

Another Q: as can be seen in the elevation, I want the diagonal parts of the roof edge to connect "flushly" to the middle part. I am not sure how to do this. Does anyone have any advice?

Thanks in advance,

Operating system used: Windows 11

Hi @christmd

Trim Elements to Roof/Shell can be used with walls associated openings to be trimmed together, but each instance of a wall, door or window can be unlinked independently.

Roof edges/planes can have different slope, so if you click on one individually, you can change its slope or mark it as gabled.

Watch the attached video.

Regards.

If those are Single Plane Roofs, you can select one roof then ctrl + click the edge of the adjoining roof. This should make them bisect. This bisector is shown in the floor plan though...

Is there a reason you are using Single Planes instead of a Multi Plane? Multi Plane roofs will not show the bisectors as Single Planes do.

it definitely appears you have a rogue SEO... hip section as operator, wall as target, subtraction with downward extrusion.
select the wall, remove all SEO's, redo operations for flanking walls only

if that is indeed not the culprit, try setting all non-visible layers to group 0. You could have a slab or wall on a hidden layer interacting with the visible wall. But given the opening appears to reflect the exact shape/location of the hip profile, I think it is a downward extrusion issue.
