Stairs
Stairs are AEC objects that use flights of treads and risers to accommodate vertical circulation.
Stairs also interact with railing objects. You can control the style of the stair, the shape of the
landing, the type of treads, and the height and width of the stair run.

Stair Shapes
While strictly rectangular stairs are predominant in modern buildings, in some
cases the edges of a flight are not parallel, or they might be curved. Landings
can also be non rectangular. Stairs allow the use of nearly arbitrary profiles for
the edges of flights and landings. In addition, railings and stringers can be
anchored to stairs and can follow the edges of flights and landings. You can
create custom stairs from linework or profiles to model different conditions as
well.
Landings and Turns
Stairs are created at a specified overall height that requires a total length based
on the tread length. Within that length, you can place landings or turns. When
you begin to create a stairway, a rectangular box is displayed that represents
the width and length of the stair as if it were a straight stairway. As you select
consecutive points, depending upon the shape of the stair, landings and turns
are created.
