staircase doesn't show like they should

[edenbensal]

I've a problem that I couldn't resolve yet.

look at the floor plan that I provided in the post (you can see it also at the 3d pic).

in the floor plan the 2 staircase looks strange (one over one)

how can I fix that?

Elements within the view depth are drawn using the <Beyond> line style regardless of the element's category.

Exceptions: Floors, structural floors, stairs, and ramps located outside the view range use an adjusted range that is 4 feet (about 1.22 meters) below the bottom of the primary range. Within this adjusted range, the elements are drawn using the projection line weight for the category. If they exist outside this adjusted range but within the view depth, these elements are drawn using the <Beyond> line style.

Post your file and I'll show you two workarounds -- one using Plan Region.
