Want to make irregular stair.

I want to make irregular stairs, so please let me know. I can't think of any other way to do it.  please help

Use Create Sketch option, defining the boundaries, risers and stair path

You can also first model the stair and then convert it to a sketch based.

 I don't know what you mean by "irregular stair", but Component Stairs can manipulated using their Shape Handles.  Is this what you are trying to do?

For that kind of gallery seating/stair I'd be inclined to use Model in-place and create the extrusions in section and then extend them as far as they would go in plan. You could also use a stair the left lower run and another stair for the left upper run. Then use Floors for the other seating and "floors/landings" required. The stairs and floors will not "join" up nicely and look monolithic so that's why I'd be inclined to go with "in-place" modelling. That would allow all the elements to look as if it was built "together".

Edit: I think you could accomplish it with the stair tool using sketch mode and multiple runs with different riser counts and height offset. Might be "easier" in-place though.

I've tried making stairs with sketches several times, but all of them have failed. I'll keep that in mind when I work !

I didn't know I could fix it with a sketch after drawing! Thank you.

Thank you so much! You helped me a lot.
