walls not healing

[Dave Brach]

I have three walls coming together to form a "T" .  Same composite structure, same layer, same surface texture, same renovation status, reference lines are identical.  Why am I seeing lines/seams in 3D?

Hi,

have you looked at their junction orders?

Some more reference : https://community.graphisoft.com/t5/Getting-started/How-Walls-are-Connected-in-Archicad/ta-p/303922

also it seems like the core material “splits” the finish (in the floor plan view). Maybe it is a material strength setting at play too.

I forgot to check that.  But yes, same junction order on all 3 walls.  If I make them all the same height I can get 2 of the 3 to heal, but in no scenario can I get all three to heal.

The reference lines all meet at the same point? They are the same composite?

It seems that the problem resides in building material priorities. Check that they are not the same between the finishes and the core layer materials.

Having finish material being a HIGHER Intersection Priority is a bad idea as they will interupt all of your wall junctions... As long as you define your layers correctly, your Core layers will terminate with each other and your Finish layers will wrap around to meet each other.
