Hi TomGernatt,

Say your first floor level is 10" and the second floor is at 150"
1 - Create a first stair with height = 70" (for example)--> select it--> set the elevation at 10"
2 - Floor tab--> floor tool--> create the landing shape--> set the thickness (say it is 8")--> select the floor--> set the elevation --> in this case the elevation will be 10" + 70" - 8"= 72"(remember that the ceiling / floor elevation is the bottom face of the ceiling / floor)
3 - Create the second stair--> the height will be 150" - 88"= 62" (88"is the level of the upper part of the landing)--> select the second stair--> set elevation at 88"

Of course, you can modify these values according with your project
