User rsdworker made two videos of building a station in Antstation. Awesome, thanks rsdworker!
He builds a fully functional station and it's basically a how-to guide of building a station.
There's a few things in the video which I failed to explain in my guide
-To activate a powerdispenser, click it again while in spawnmode powerdispenser
-Utility going in the Zenith or Nadir (across Z-levels) directions, needs to go via walls
-There's no atmospherics mapmode, so you can right-click a tile, and then click the gass to view the spread of the gas across the station
In addition to how the station is build in the video, it's recommendable to build a layer of wall both above and below your station to prevent the leakage of precious atmosphere.
I also see plenty of bugs (including the wall heater not going on, but rsdworker manages to work around that). So expect that kind of thing while playing.
