Column

Columns are passable structures primarily used to hold up roofs,

Acquisition

Columns can be constructed, each requiring 20 Stuff (Metallic/Woody/Stony, 200 for SMVs) and 750 ticks (12.5 secs) of work modified by the construction speed of the builder and the work to build factor and offset of the material.

Once constructed, they cannot be re-installed, they can only be deconstructed.

Summary

Columns can hold roofs up to 6 tiles away in all directions, like a wall. Destroying all of a roof's supports will cause it to instantly fall, injuring and possibly killing anything below. Columns also provide a minor beauty increase.

Columns can't usually be stood on, similar to a fence or barricade. Columns do not block LoS, can be walked through without slowing anyone down, and provide 25% cover for pawns shooting behind them.

Requirements

Columns are needed to satisfy the requirements of a ritual room or throne room (for nobles Knight and above). If a room's requirements are not met, then colonists demanding them will become unhappy.

Analysis

For holding up a roof, it's usually better to just create a lone wall, which supports the same number of roof tiles and costs 4x less. Columns provide less cover for raiders, can be walked over, and don't block the radius of orbital trade beacons. Columns also have much less health than a wall, which can be helpful when creating a falling roof trap.

Like sandbags, barricades, and fences, it is not possible to stand on top of a column (however, it is still possible to shoot while passing on it). Unlike the structures mentioned above, columns do not slow down pawn movement.

Styles

Ideoligions allow the selection of styles which then change the texture of the certain items and buildings when constructed by the colony. These style variants can be crafted if the colony has the selected style, or can be looted from raiders from factions with the requisite style.
