Wall and Ceiling layers not joining correctly

[nemig]

Having trouble getting my exterior "soffit" to join correctly with my exterior wall. It's a metal panel system that dies back into an eifs wall. The inside corner is working somehow but the outside is not. I'm using the pick walls tool when creating the ceiling and checking "extend into core". I've doubled checked the assemblies and unless I'm missing something they have the same layers with the same assignments, materials, and thicknesses. But I still can't get this outside corner to match up? Joining the geometry gets a few of the layers to match, but switching the join order isn't helping. It is only giving me the two options shown below.

I've looked into a bunch of similar threads and there seem to be workarounds for gyp on stud walls/ceilings that only have two layers but can't find anything about assemblies with 3 or more layers. Even with just gyp and stud it seems to be a pain point for a lot of other people. Is there a solution here other than resorting to cut profile or detail items/regions?

Thanks.

Here are the assemblies. Wouldn't let me post more than 3 attachments in the original post !

I'm not following. Might make more sense if you just post your file here and let us pick the views to examine to aid our understanding.

Sure, see attached. Here's a pic of what I'm trying to make happen as well. I've used the cut profile tool but you can see that isn't a great solution either since it leaves lines behind and you cant control the lineweights.

Like this?

The last bit can be done via Cut Profile in view.

After fixed with Cut profile.

2022 file is attached.

Close! Outer layer looks good but not sure why the air gap, insulation, and sheathing don't match up as well though. It's odd ceiling-to-wall joins in section dont seem to behave the same way wall-to-wall joins do in plan.

this?

Yes! What was your method there?

Me?  Parts.  For now.  Is that the condition you want?  

....Merged Parts. 

[nemig]

Yep, that's how I want it to look. I've experimented with parts but couldn't get the dividing lines between the parts to disappear like you did in yours. Are you using the lineweight tool to override them or something?

No. All Parts.  It's a quick solution.  Activate shape handles, drag parts to meet and Merge Parts.  Bada Bing!

Gotcha. I overlooked the merge parts button. I'll use that method moving forward (part of me wishes they would just do it automatically like walls though 😢. Seems like the natural behavior). 

Thanks for your help
