Possible to set height by default?
Is there a way to set it so  entire server has a height set by default.
Instead of having to do every elevator or user commands.

So if we want height set to 20 it can be all of them.
Just curious, do you really want to auto deploy 20 elevators? I'm working on adding new hooks, and a corresponding plugin, that will allow players to naturally deploy elevators beyond the default limit of 6 floors, which I assume is what people will typically want. It will also have a feature that allows the lift to maintain position as you add more elevators to the top, so as long as you are using powerless, you can fairly quickly build a tall elevator yourself by alternating between raising the lift and placing other.
I dont see how you plan on getting native placement past the limit when the placement guide is completely client side. If you were planning on changing the MaxFloor variable in ConstructionSocket_Elevator it won't change the same variable client side which actually lines up the placement guide for the client. If its not valid placement on the client there will never be a RPC to the server.
I didn't realize it was client side and not server side. Have not messed with elevators very much so its my fault for not researching.
Thought it would be a max variable with elevators. But now realize that is not the case (even though I wish it was).
You will see...
Then I assume you are going to fiddle with the floor numbers assigned to each level to trick it in to thinking its less than the limit like so https://gyazo.com/86245684569476e95b94a8f4e34759b3


While exposing the floor property will be easier you can also change the floor number by sending the elevator some dummy load info
Yes, originally I used Built/Kill hooks to update the Floor so that the top was always 0 while the others were correct. Only issue is the lift cant move from the top. With new hooks, I would temporarily patch the top floor to the correct value only when movement was initiated.

But there's another trick Jake showed me that makes it much simpler, requiring a specialized hook.
