Unexpected line in wall intersection

[maurotrotta]

The intersection of two composite wall have a line that I can´t find out where it comes from. I have no override and the walls have the same profile. I guess it have something to do with the core of the composite wall (it is a dry wall) but when edit the skin and line structure of the wall and try different configuration, the line still is there. Any ideas?

If you look at your building material strengths, I bet you will find that the gypsum plaster is stronger than the air space.

Try it the other way around, the air space should be strongest.

That was fast, thanks. I was changing the airspace of a different building material, until I found the one for the wall profile I am using.
