Fences and Walls are a special type of structure that can be found under the Fences and Walls () category of the Construction (F11) window.
There are 12 different types of fences and walls. Each has a unique model and property, such as some obstructing movement or blocking gunfire.
When placing a fence/wall, the G key can be pressed to locate and snap to the nearest existing post. The SHIFT key can be pressed to angle-snap, like with roads.
They can be placed through or within water, and have a maximum length of 1km (1,000m).
The Custom Wall or Fence is a player-designed blueprint, much like other buildings.
