I'm sorry @pavankumar.h, but I truly do not understand to your reply and notes regarding "stringer being in a specific mode", "The stringer is part of a predefined stair type and does not allow direct path editing" or "The stair component is locked or constrained by other elements", "switch to a different stair editing mode" etc ...
Honestly, how? Are we talking about Revit? I feel like that there are some mysterious editing options, buttons and properties I am not aware of.
Can you or @mari.shimode please share a quick video or a gif that will show not just to me, but to others as well this "edit path tool for stringers" because to be really honest, I do not recall ever seeing it and I've been using Revit for good 15 years. I'm sure that your video will be very helpful to all, looking forward to it. Just as a test, I tried that with ootb stairs in ootb template too - and no it doesn't work in my world.
