Dimension heights of vertical elements of doors, windows, and wall openings either in the outside or inside of the section.

INTERIOR DETAIL DRAWINGS
Interior detail drawings illustrate small portions of a space or object at a large scale. They are intended to accurately show materials and finish application. Detail drawings are not always drawn in section and may include an enlarged drawing of the floor plan or elevation (Figure 46). Section details provide information on the location and construction of different parts, the relationships of these parts to the surroundings, and the juncture of materials. Details are referenced from plan, elevation, and section drawings.
