Abstract
The slope of the Balcony and height of the stoppings shall first
be considered, so that the steel used in the construction of the balcony
may be designed accordingly.
When "setting up" the sections of the Parquette circle or balcony
in the theater, it is desirable to sight from the eye level of the spectator, which will be considered as 4 feet 2 inches from the floor when
the spectator is seated, (.and 4 feet 10 inches to 5 feet when standing).
The theoretical principles used when fixing the heights of the steppings
upon which the seats are placed are as follows: A point is fixed on the curtain line 4 feet below the stage level,
and from this point, after the distance from the stage, the stepping,
and the floor level is placed, set up the spectator's eyes 4 feet 2 inches
above the floor, vertical with the back rail of the seat. Now from the
4 feet point on the curtain line, a line should be drawn cutting through
the eye of the spectator in the first row, and produced until it cuts
a vertical line set up at the back of the second row. Then from the
point where the vertical and radial lines intersect 5 inches is measured
up and that point gives the eye level of the second row. From the point
below the stage, a line is drawn through the eye level of the second
row, and produced until it intersects the vertical line set up at the
back of the third row, and from that point again measured up 3 inches
for each row, and from each eye level, measured down 4 feet 2 inches
will give the floor level for each stepping.
