Wall junction problem

Hi everyone!

I have some trouble figuring out why, in some cases, the junction between two identical walls is not mitered! I've tried pretty much everything and nothing works. Is there a setting that I don't know of? I have to mention that If I open a new archicad project with the default settings it works as expected, so it must be something connected to my template because this happens in all my projects!

Hopefully someone has an answer because I really need this to work!

Thanks!

Archicad used to mitre corners but has not done so since version 17 from memory.

Each skin of your wall will trim according to the Building Material strength - stronger materials will cut away the weaker ones.
Where the BM is exactly the same strength (i.e. same material), Archicad will decide.
You can override this with the 'Junction Order' of the walls.

If you really want to (but I don't recommend it), you can go into the project preferences and turn the Legacy option on for intersection and surface methods - but this will affect other aspects of your model - read the info button for more details on what will be affected.

Thank you! You are a life savior!

I'm working on a urban planning project and I'm using walls instead of lines in some cases, and for this purpose the legacy settings for wall intersections are the way to go.

I've also learned that the "outside face" of the 2 walls should be on the same side in order for the junction to work.

A small part of the time where they dont interct, you'll have to go to the wall setting and select "none" for wall end line and manually draw in the 2D line.
