Crossbeam

"A crossbeam to allow placement of roofs"

Crafting Recipe
Tool: Hammer

How to use
The crossbeam needs to be supported on at least one side before the roof tile can be placed on the same place as the crossbeam is.

The roof will then automatically stretch to every tile around the crossbeam except the front. The roof can be extended, this requires support on either side of the next crossbeam.

You can remove additional support walls later so only the side walls remain.
