Flat Roof Parapets are a PITA! Can't get intersecting walls to look right

[VWCALBUG]

I've read up on a lot of the articles and help for parapet walls on a flat roof. I generally have it working alright, albeit what a slow and PITA approach! I guess not too many people using home designer do this, otherwise they would develop some better functionality! Rant over....

 

So specifically, I have different roof elevation heights and intersecting walls that the corners and wall caps I just can't get them to render correctly. There's variations all over this roof that I believe many places it's combining the walls even though they are different heights. I've added breaks on many of these walls, but they eventually just combine together again. For the parapets I defined a wall type that has a stucco interior, I suspect it's not handling in some cases the interior/exterior wall positions are different because the way these elevations come together. I'm not sure how to rectify this or describe it, so I'll post a bunch of pictures.

Tips:

 

Attach your plan file.

 

Always say what program and year you are using (like Pro 2020).

 

Vector View often shows alignment and other issues better than Standard View.

I use Home Designer Pro 2023 here's the attached plan. You'll see in 3D almost anywhere there's an intersecting wall of a differing height, either the top cap or sides of the walls aren't right.

Start with a general plan cleanup. 

 

Align walls one over the other.

Reset wall top and bottom heights.

Fix the foundation.

Reset railing walls to non railing walls, or use railing walls everywhere.

I wasn't able to watch your video before you removed it, can you repost? I'm trying to fix the foundations, but the floor height is still lower than the rest of the house, I cannot figure out the north side and why it looks like the foundation is below the terrain compared to the garage
