Connecting rooms through doorways + Inspection tool

Wow looka that - first time I’ve effortlesly got a result like a veteran! Well, after doubling the no of photos by blasting the corners where the Components wouldn’t join up. Though I bet if I deleted that Component and Aligned again it wd go back to 2 or 3 Components.

That’s one room done, all walls - now the other one, then the look-both-ways through the doorway.
