Stairs - hight to next level
Designing a 2 story building. Working on a flight of stairs from Level 1 to Level 2.
Level 1 is Wall-height 303cm, Level 2 is Floor-height 22cm. My understanding is that the stair should be 325cm high.
However, the top of the stairs is only level at 330cm.
Why the extra 5 cm?

Re: Stairs - hight to next level
Check your level elevations, that's probably where the difference comes from.
If you have problems with the relations between level elevations, heights, and floor thicknesses then read my manual "Levels explained" on dodecagon.nl

Re: Stairs - hight to next level
Thanks, I learned from your link that the elevation is relative to the top of the floor, not the bottom (ceiling lower level). Solved my problem.
Additionally I miscalculated the number of steps! Should have been 16 but I only counted to 14.
