Stairs, elevators & escalators
Adding level changers
Stairs, elevators and escalators are all commonly called level-changers. They are very simple to add. Use the Point tool to add a POI at the correct location, and then define it as Type: Staircase/Elevator/Escalator per your need
Level changer also have an additional attribute - Floors. That allows you to specify which floors in the building can be accessed with the same level changer. If e.g. an elevator does not stop at floor 2, simply unselect that floor. The editor only shows you the floors that you have added under your account as options. So if a floor is not available for selection, make sure to add it first under "Locations".
Grouping level changers
Elevators are typically easy to setup, as they go through the building in a straight line. Often with escalators and staircases you will encounter a difficulty: the starting and ending point are not exactly the same, as in this example:
For that purpose, you can use the grouping functionality. Instead of adding one staircase that goes through both floors, you would be adding a separate icon for each floor at the correct location:
With escalators you will also have an additional configuration - direction. This allows you to specify which direction the escalator is going to. If the Up and down escalators are next to each other, in order of simplicity, it's easiest to use the default "both" option.
