Preview Mode For Building!

Ever have a giant structure, like an Animal Pen or a Vault, or something smaller like an Armorer’s Bench, and wish you could tell if something fits right?
Well how about a Preview Mode? It’d be like switching to another camera to observe all the different angles. You’ll be able to move the piece around however you like with ease.
Please implement this!

At least as an admin mode. :+1:t2:
