The Elevator is a utility subcraft. They must be a smaller part of a larger craft in order to be used (i.e., they must be a subcraft). It is a structure that can move anything made of Allowed Blocks on Craft, only up or down. It cannot be transported in any other direction.
An Elevator must always be separated from its larger craft using blocks that are allowed on the larger craft, but not allowed on the Elevator. This is so the Elevator does not think the larger craft is part of itself, while making sure the larger craft can carry the Elevator.
If the Elevator is not properly separated from the larger craft, it will move the entirety of the larger craft, causing the larger craft to think it has been destroyed and thus sink. You are therefore highly encouraged to experiment with the Elevator on the creative testing server before using it on Nations.
Elevators are controlled using Subcraft Relative Move signs while controlling a larger craft. The Subcraft Relative Move sign must be placed on the Elevator. When the sign is right-clicked, the Elevator will move up and down, independently of the rest of the craft.
You can use Remote signs to trigger a Subcraft Relative Move sign remotely.
