I've been building on my vault little by little but now I've run into a problem. Every piece that I place in the G.E.C.K. are misaligned to the old ones. Any way to fix this without having to rebuild the whole thing or manually editing every new piece to fit with the other?

Turn on grid snap? You can adjust the grid size in preferences.

Tried it. Didn't work. Is there a way to shift all pieces at the same time? Like select all of them then inch them around?

What you should do is select a snap master reference piece by holding Shift and Q. The cursor will turn into a white crosshairs, select one piece. Then turn on snap, grab the other piece and move it slightly - it will snap onto the first one perfectly. Then move through the cell snapping pieces until they are all perfect. You can re-select the master snap reference each time you need to snap two things together perfectly, usually you need to pick a new reference when you switch from snapping wall/hall pieces to furniture, etc.

Luck,

THANK YOU!!! I realised why the misalignment happened. I used the big sewer tunnels as a connection to my vault door but when opened you could see the Ether through the gear points then I moved the whole thing.
