Wendy,

Your travel line is not allowed. In other words you have one tread actually
takes you to a drop off, then the next tread is not as wide and thus creates
the problem. I'm guessing you ran out of room to make this stair work.
Please forgive me if I presume to much, but does your code allow
this multiple of straight, landing and winders? In any
case, according to stair gurus, that is a confusing rhythm for users.
On winders, not a good idea to terminate in a perfect triangle shape,
regardless of code. Most people travel a stair on the inside rail
(the shortest distance). So allow for a footstep on this narrowest portion. Locally we provide 6" (15cm) but more is better.

If you really must build this stair (perhaps it is an existing condition) you probably will have to build it out of bits. The simplest way would to use slabs for the treads and carriage. You can use the treads as SEO operators to shape the top of the carriage. The bottom looks like it will be rather tricky. Subtracting a mesh from the bottom might be best. Good luck.

Or you can build each section of risers as separate stairs.

get yourself Revit (i was thinking that i will never write this)
but as i look what you can do there in Revit--- archicad is way behind . . .If next archicad ver dont get modeling tools i will go to Revit...

That Revit stair is just as useless as any other stair generated with a “stair tool”. If you want to model a stair for use with working drawings or a material list, model it yourself.

did you really test Revit stair?
I did
Just a dummy U shape concrete stair
even that was bad
I am also not that happy with our stairs but why advertise for another product that is not better (for stairs)?

I agree. Stair tools are great for off-the-shelf situations, but you run into problems the moment you want bespoke detailing. Stairs can be surprisingly complex, and often building them from scratch will be faster and more useful for detailing/scheduling/manufacture than using a semi-automated solution.

I've attached a few examples of stairs (and stair components) I've modelled in the past within ArchiCAD, some of which were directly used for manufacture.
