Drawing 3 flights stair u shape

[Anonymous]

I am having problems drawing a 3 flights stairs, 4,10,10 steps each flight with a 100MM opening in "U" shape, I can draw the 1st and 2§ flight, but can't do with the 3rd. I can't draw it somehow the 3rd flight can't be drawn overlapping the first 4 step flight.
What am I doing wrong?

I don't think you are doing anything wrong - stairs can't overlap vertically. You need to start a new stair once you start to overlap - at least that's how I have been doing it.

Thank you, this might be a wish, nevertheless that is common to overlap stairs in 1st floors, due to their height.
