This item is currently only available on the Aux2 staging branch and is not a part of the release version of the game.
The pipe tool requires the authorization of Tool Cupboards to determine whether a player may alter connections within the confines of the building privilege. Players cannot interact with Industrial In or Out ports unless authorized and holding the pipe tool.
This tool is currently only used to service these port types. Blueprint In / Out ports exist and are interactable with this tool but currently serves no purpose.
Means of acquiring a Pipe Tool
Currently, the pipe tool is craftable via the Work Bench Level 1, and is available as a default blueprint. This will likely change when the item is released in the official update.
