Breaking two walls in the room corner

[dadep]

Hello,
I have to resize one vertical wall, but dragging it takes the horizontal wall with it.
How can I break the two walls in their intersection,so that the horizontal one is left unchanged ?

See the attached sreen2gif for better understanding.



thanks in advance
Best regards
Davide

Cut&paste the vertical wall. If it was attached to another wall at the bottom that is not visible in the image you can join that corner again.
