Autodoors are powered doors that open and close a lot faster than regular doors of the same material.

Acquisition

Autodoors can be constructed once the autodoor research project has been completed. Each requires  25 Stuff (Metallic/Woody/Stony, 250 for SMVs),  40 Steel,  2 Components, 1,100 ticks (18.33 secs) of work modified by the construction speed of the builder and the work to build factor and offset of the material, and a construction skill of 6.

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

Summary

The autodoor draws 50 W of power at all times. If not enough power is available or the door breaks down, it behaves exactly like a regular door of the same material.

Contrary to the in-game description, not all autodoors allow unimpeded movement. Actually, a powered autodoor opens at 400% speed. This means that all powered autodoors that are not made of stone indeed do not slow colonists down; move speeds that would be high enough to have an effect in this case are rarely achieved in practice. Stone autodoors, however, open only slightly faster than regular wooden doors.

The below animation shows a comparison of different door types and materials (the animals all have the same movement speed of 5 c/s, comparable to a fast human pawn).

Notes

• Work to build an autodoor is 130% the value of the corresponding regular door.
• Most other relevant stats (except opening/closing speed) are unchanged from regular doors of the same material.

Analysis

Autodoors open faster than regular doors, but are more expensive - building a large number of autodoors costs many components, and you need to power them. High traffic doors should be converted first. Before the late game, you should compare autodoors to wooden or held open doors:

• A held open door takes no time to open. If a door does not need to be closed (e.g. a door safely inside your base where temperature control doesn't matter), then you can just keep it open, saving resources.
• A wooden door opens relatively quickly. If a door needs to be closed, and is not opened frequently, then consider a wooden door. Since wooden doors have low HP, though, autodoors can be used in places you expect combat to happen.

Since autodoors not only open, but also close fast, they help when a pawn needs to flee from a threat. This means that compared to regular doors, autodoors are more likely to close before the pursuer can step through or block the door. This makes them good choices for main entrances to the base.

Material selection is also key. Generally speaking, autodoors are put in positions where their security matters, as otherwise an wooden or open door could be used instead.

• Plasteel has the highest HP and is not flammable, but is expensive. Uranium has the 2nd highest HP, nonflammable, and somewhat cheaper than plasteel.
• Steel has decent HP, and is cheaper than the above metals, but is flammable.
• Bioferrite is flammable, but has the lowest wealth footprint of any material while boasting good HP and opening speed.
• Stone autodoors open slower than other types of autodoors, though are still reasonably fast (opening slightly faster than regular wooden doors). They are cheap, have good HP, and are not flammable. Note that if the power goes out, then stone autodoors will open even slower. This can be a liability - a blackout situation can quickly turn into an emergency situation.

In the late game, where the material costs are irrelevant, then autodoors can be used anywhere you'd need a closed door.

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.
