Walls don't join on plan. (Clean Wall Intersections is ON)

AndreGaspar · ‎2025-08-18

Hi!

I'm having a problem with walls not joining in plan. Clean Wall Intersections option is turn on and the walls are on the same layer and priority.

I there any other option I'm missing out that affect he walls connections?

Are no walls joining, or just a few?
Next to clean intersections and layers+prio I would add Reno.

Or, a special case: zero height walls.

Sometimes when moving walls they do not intersect again cleanly. Trying to rejoin reference lines helps there.

Make sure layer priority is not zero.

Any other number is fine.

Every now and then I run into this problem as well: suddenly no wall connects to any other wall anymore. The only thing I found that worked was starting a new file and merging it with the other one via File > Interoperability > Merge.

Would like to know if there are other options....
