Add A* Grids to the different floors and make the elevator bank a member of the A* navigator. Then you just use the standard activities to have the patients move to objects/locations on other floors.

The navigator will always choose the elevator bank that results in the shortest travel route. One elevator bank can contain multiple elevator cabins/shafts (just resize the object along the x-axis to add/remove them) and has an internal logic to control those which mostly works on a First Available principle.

If you have more than one elevator bank and want to control which one the patients use you will have to implement custom logic that first sends them near the chosen bank, so that they will use it because it is the shortest path.

Hello @Pert P,

You needed to add in another a star grid to the floor where z =30 and the staff needed to be added as travelers in the A star navigation.
