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.enCreative Commons BY-NC-ND 4.0-USdesigngraphical constructionThesis / Dissertation
