Dimension important levels such as footing, grade, finished floor lines, finished ceiling lines, top plate, or ridge of the roof in the outside of the section.
Dimension heights of vertical elements of doors, windows, and wall openings either in the outside or inside of the section.
Dimension any built-in features or any elements that need to show construction details.
As on interior elevations, sections are primarily concerned with vertical heights, too. Indicate horizontal dimensions only for things that are not informed on the floor plan.
