Thank you for your answer .
A very good method of adding subsequent landings at the same level. I haven’t tried this before.
Unfortunately, it looks like this won’t work in my case. The railing looks very strange.
I would like the railing to be very smooth and stable when turning.
Maybe there should be flights instead of landings to smooth out the railing?
Another problem is that when adding a flight after several landings, it is impossible to add a cut string in the last flight.
I am attaching a photo and file of these stairs.
