I keep hearing about all of the fancy things you can do when settlement building, such as how to move walls, items, etc. closer to you, further away, up and down. I play on PS4, and so far the only building "trick" I know is how to spin an object around using R2/L2 triggers. And that's it. I've tried pressing other buttons and can't seem to do any of the other "tricks".
So...how do I do that? Hopefully this is a pretty straight-forward question...
