Complex Wall Showing more than it should when connected

[Anonymous]

I have 2 wall profiles that are sitting ontop of eachother.
They are on different levels.
For some reason they are changing depending if theyre like connected, and it just adds this extra bit poking out and I have no clue why. This doesnt happen if they arent on top of other complex profile walls.

This is due to 2 walls vertically colliding, and the 2 references lines of those walls being in the same location. When two Walls overlapping and collide like that, they try to connect.
If you prevent the vertical collision, it will be ok.

I have this issue regularly and sometimes changing wall direction of one or both walls fix it.

If you want to move the reference line, as described above, then go to Edit / Reference Line and Plane / Modify Wall Reference Line, which will move the reference line without moving the wall geometry.
