Have you just built a fairly large mining craft and want another to start a fleet? Don't want to spend the time building an identical one from scratch? Yeah, me neither, which is where blueprints come in. Whilst in a ship, you should be able to save a blueprint of the ship under a chosen name. You can then simply open a menu and spawn in a blueprinted ship at any time. This could work differently in creative and survival modes, for example in creative mode it simply automatically spawns the ship, and in survival it checks first that you have enough resources, then spawns a skeleton ship to blowtorch until it is fully complete, like they have shown in trailers.
