Wall composites not clearing correctly

[MrSoleil]

Why are these not clearing correctly? The outside materials are the same, the cores should connect with the beige one on top. Priorities are set correctly (760 for the beige, 750 for the CMU, and lower for the finishes).

I think they are clearing up as designed – just maybe not like you'd expect. On the left there seems to be another wall, and I guess the reference lines of both horizontal walls meet, and thus joining. Even more so since the CMU has a smaller prio than the beige part.

For the walls that you want to join as a corner, try raising the value of their 'junction order'.

If they are a higher value than the other walls that are connecting, then the trimming priority should be given to them.

Thank you, but these walls do not connect to the 3rd one. Other corners with no 3rd wall behave the same. The finishes should connect - they're the same materials. But the CMU/Concrete overcomes the finishes and I've no idea how to fix that. 

[Barry Kelly]

OK, then it is building material strengths.

The air space skin (the empty fill one) needs to be stronger than everything if you want that to trim.

And ideally the outer finish skin should be stronger that the inner skins.

At present I am guessing the beige skin is stronger than everything else.

[MrSoleil]

Thank you, will try that. 

[MrSoleil]

Works for the most part but is creating issues like these: 

It boggles me how ArchiCAD has not fixed this obvious issue yet. Seems it would just require it to force clean corner finishes 🤷🏼‍♀️

Try this.

Duplicate the Air building material.

Use the high priority air for the outer walls composite, and the lower priority one for the inner walls composite.

Does that work?

[MrSoleil]

Can't do that, these two walls need to clear at corners (the CMU + concrete), but on instances like this one they should obviously connect by core. I guess the only way would be to duplicate the wall composite, but it's unproductive. 

[Ernest Atanasiu]

I would recommend the opposite, outer materials are lower priority always, to avoid the kind of issues MrSoleil posted. 

Have you tried moving the reference line to the outside of the strongest material (the core usually) ? Refence lines should not intersect with the outside wall.
