problem creating staircase

3dbuilder — Mon, 14 Jul 2025 15:47:41 GMT

For some reason I can't create these stairs. i 27 stairs for the height 16.74. The tool doesn't let me continue building the last stair line as shown in the added photo.
Could someone help me understand what I am missing?

Would appreciate any help!

Operating system used: Windows 28

Hi,

Just so I understand what you are trying to achieve: do you want your stairs to "spiral" on top of themselves? That is not possible in Archicad, you will have to split the stair into multiple parts.

I duplicated two sets of stairs to show what I mean. i have a one and a half floor (from entrance to garage), the height difference is 452 cm

I try to make a normal staircase, not a spiral. just a normal rectangle.

In my first message you could see that after stair number 20 i am not allowed to pull the direction of the stair upwards.

Yes, bad wording on my side.

I meant spiral as in a stair that overlaps onto itself - even rectangular in shape. That can't be done out of one single element. You will need multiple stairs to achieve that.
