Hello... I am trying to model a staircase similar to the one I show you in the attached image with several corners. So far I have solved it with several independent stairs (one on each side), but I wonder if it can be done with a single stair element. My client has it this way in one of the files he sent me for reference.

I have also tried to make a single staircase and edit its points with “modify points” and “bend line” but if I edit it, it returns to its original state (something that I think should not happen), destroying everything I had modified.

Is there any way to make it in one go? or at least, is there any way to join several stairs into one (and still be a stair, not a 3D Object or something like that)?
