Where to begin on construction simulator: How do I allow the player to snap pieces(prefabs) together?

@SFoxx28 Start by breaking down the problem then implementing it piece by piece. Here is a start: - a way to grab and select pieces in game. - a way to move the pieces in game - how the item behaves while being moved (does it ghost through other pieces?) - having the prefabs that will be instantiated and moved. (start simple with a square) - next is how will they snap? You will have to have locations that they connect to. Start with the simplest type of connection, a rigid one. make it work for two squares. Next you can add other types of connections and make it so only certain pieces can connect to others.

Implement the simplest case first. Implement the parts needed for that "simple" case.

I hope this helps.
