Building System Question

Hey, I’m about to start working on a Building System and there’s one thing I’m concerned about.
Firstly, the building system is limited to your plot, and will be a grid system meaning it’ll only be able to move 1 stud.

With this said, I’ve realized that, when rotating an object from the middle, it’ll offset it from the grid system, meaning it’ll no longer line up with the grid system.

On top of that as well, I’ve been wondering how to make sure the full object (example will be wall) is in your plot.
I was thinking of using Region3, however noticed that you’ll be able to place the wall half in, half outside and Region3 will still detect it as in. Anyone have a solution to this?

If your ‘block’ size is 10x10x10 then make your placement area 10 studs smaller than the baseplate. This allows the 5 stud overhang on each side of the grid.
You should be placing the ‘block’ at 1/2 the X and 1/2 the Z value of the grid so that rotations aren’t around the corner of the ‘block’.

I’m no good at scripting this type of system, but please Search the forum because I know this question has been answered in quite a few posts in the past.

@EgoMoose has a great tutorial on making a furniture placement system.
