Rust Like Building System?

Just wondering if there’s any rust like building addons for GMod? Or any building were you can snap walls to foundations and ceilings to walls.

iirc someone was working on Rust version on garry’s mod but I belive they stopped working on it, other then that I haven’t seen any like Rust/ARK building systems, would be cool tho to see them. like this?

No like a snap system where you snap foundations together and then you snap walls or doorframes together and then ceilings, etc.

Would be cool to see something like that in GMod.
