Overlapping stair display in plan


I have a problem with my stairs in Archicad 24. There are three flights whose structure overlaps a bit.


The problem is that on the upper floor where the structure overlaps, the part below is visible as you can see in the screenshots. Has anyone else had this problem?

Yeah encountered it, tried adjusting the display setting of the stairs but didn't manage to make it work. Work around I did is just cover it with Fills.

In the end what is your Objective?

Archicad stairs can not overlap in any way within the one stair object.

You have to create separate stairs so they don't overlap.


I guess technically in the example shown, they don't overlap.

They just wrap around themselves.

Which they can do....




But there does seem to be a problem with the display if it is within about one tread of itself.

Further apart it is fine.




All I can suggest is to split the stair into 2 objects.
