Hi all, architecture student here. I'm having a couple of issues with the wall tool, the first being when I move a wall (A) that was previously connected to another wall (B), the hole that A was cutting in B stays even after A is moved. I hope that makes sense. How can I fill/repair this hole again? Hopefully this screenshot will illustrate better what I mean (I can't seem to insert an image into this post so I've had to link it). Thanks!
