Seriously, is there some kind of cheat for building a house without the roof falling apart? This stopped being fun 4 hours ago. Like a perfect structure cheat code?

With regular beams and wall/floor panels, you can only build 5 away from any grounding point. If your roof is collapsing, it just means you are trying to place it too many pieces away from touching the ground, tree, or rock.

The console commands won't help you except that you would be able to use iron beams, which can go much further from foundation and when you connect another piece to them, it counts as you putting that piece on a foundation. There are lots of videos with tips about this, and how to use longer corewood beams to help lessen the restriction a little. Or like someone else said, perhaps a mod that changes integrity physics.
