Stairs around a large cylinder?

is there an addon to make stairs around a large cylinder ?

i can make i around a small column with empty and array
but for large cylinder it is hard to control
number of step function of step height

Usually the suggested method to create spiraling stairs is with curve objects.
Here’s a guide tutorial demonstrating how to create such a staircase with curve objects:

I can give you this geonodes setup (Blender version 3.1.1)

staircase_geonodes.blend (111.2 KB)

thanks for the BL 3
but my PC is too old i cannot use BL 3.0 only last version of 2.9

might be useful for other people

thanks

The tutorial I shared is still compatible with Blender 2.8.

If the screw tool is still a tool, just use that with a single stair and an additional edge to define the vertical dimension, and once done, delete the geometry created by the loose edge.

video is same method i use to do it around a column

but it won’t calculate how many steps you need between floor function of height

i as hoping someone had already done an addon for this kid of stairs.

There is this older one…looks like it has the controls you might need…

will look at it

inside outside stairs on a large cylinder

and not so easy to get a nice stair

thanks
