Thread necromancy! What build menu are you referencing?

. I personally made my own elevator used the elevator floor under general industrial tab in the build menu closed the shaft off and boom it worked np I'm not sure exactly what tile mod its under but yea I found it under general tab under flooring its the second elevator floor choice not the black one. also you might need to change build menu settings for server or your game. I rent my server so

What dark magic is this necromancy?!?

Anyway, this works by looking for some tiles in front of your character:

"fixtures_escalators_01_48",
"fixtures_escalators_01_49",
"fixtures_escalators_01_50",
"fixtures_escalators_01_51",
"fixtures_escalators_01_56",
"fixtures_escalators_01_57"

And then looking for them above and below, and if it finds a match, it adds that match to your context menu.

So yes, if you use the brush tool or something and add the elevator door tiles stacked above or below each other, it will work. They can also be offset up to 4 tiles for like freight elevators that have an opening on the other side.
