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). 

[MrSoleil]

Same thing is happening even if the ref line is moved to the outside of the core. 

Material strengths from the outside (right/down) to inside:

- Plaster 601

- Insulation 601

- Concrete 900 / CMU 800

- Air 600

- GWB 600

[MrSoleil]

I did one more thing, set the CMU and the concrete materials to be 900 both. 

It cleans correctly now. 

I am only asking myself how does archicad know concrete should be dominant here in these connections? Will it not make the CMU "eat up" the concrete somewhere? 

(as you can imagine this is critical for structural coordination)

It might be controlled by the order you place the wall or maybe can be controlled by the junction order.

In this case leave them as 800 / 900 so they trim as you want, but make the outer insulation material (honey comb) stronger than 900.

It should trim to itself and stop anything passing through it.

That's not working as inverted corners get the insulation cutting through the core then.

"cleaning up as designed, just not as you'd like"...
how about not cleaning up as decades of architectural graphic standards require? No doubt, this is how the software is designed... but we shouldn't be complacent about sub-standard drawings that defy common graphic standards. I'm probably the least picky person in the industry when it comes to line weights. I think a set of drawings with only a .01mm pen for fills and a .2mm pen for lines is just as legible as a drawing set with 10-15 pen weights.
But if my boundary cut line is .35mm and my inner skin separator lines are .15mm, and I suddenly have .35mm injected into my assemblies, I have a software that isn't working the way it needs to be. Working the way it was designed? absolutely. Designed in a meaningful and useful way? absolutely not.

in your sample, have you set core/finish levels in the composite settings? that could be a starting place if bMat priorities aren't fixing it.

This may be random in the case the Intersection Priority Number of the two Building Materials is the same.
 However, you can use the Junction Order field in the Model panel of the Wall Settings Dialog to make it explicit. Just make sure the Junction Order of Wall you want to be stronger is higher than that of the other. So, let us say you want the other core to cut the concrete: just increase its Junction Order number (it is 8 by default).

[MrSoleil]

Thank you Laszlo, I have completely forgotten about that function.

... and if you need a lower Junction Order on the other end, this is the tool of choice:
