Can you post a picture of the wall you are trying to apply the stair. You know... an image worth a thousand words.
Cheers,
Paulo

Problem is that the profile of the wall changes, depending on elevation. I think I cannot use the function "create stair using selection", and also with the stair library I'm not sure if there is a solution.
Only option that may work is a SEO?
Hope you can help.

Since you'll probably want some fancy stair to go around such a fancy wall - like cantilevered treads, say:
use the rotate and multiply function to climb an array of stair tread slabs using the wall curve focus. Then displace three treads outward proportionate to the wall displacement in 3D. This is easy since you are sliding each slab along its axis. To get consistency, use the top, mid and bottom treads to establish the arc and move the other treads to align in plan.
As the treads move outward from the focus, naturally the rise/run will change so use deeper treads than i did because gaps appear near the top.
For a guard, use a fitted ramp like the ACE library Ramp C prism. The standard Curved ramp 13 seems to have some odd breakovers....
For a handrail use a copy of that ramp with the dimensions adjusted to suit..
So I'm an idiot for doing it the hard way.....

I've attached a snippet from the project showing a cut-away into the central stair, which rose through an elliptical, conical central core and incorporated landings at irregular intervals. Contact me if you want something like this, but it would be done as a one-off exercise, i.e. I don't this this will be solved with generic parts.

In the meantime I have managed to whip something together with SEO, a cone and slabs. Attached the result. I'll post a second pic in a moment.
Thanks for your help.

Haven't used it much, so not sure if it suits the situation with the cone, exactly.
