Elevation marks are used to indicate which direction and from which point on the floor plan is drawn. The elevation mark consists of a 1/2" diameter circle, an arrow that indicates the direction of sight, and two numbers. The upper number tells the elevation number on the sheet and the lower number indicates the sheet where the elevation is drawn. Elevation marks can be placed at each spot for different elevation views, as shown Figure 14. Or multiple elevation symbols may be used for the elevation views that are drawn from one middle spot of the space (Figure 15).
