Figure 6.12A Four exterior elevations of a house will normally accurately depict its features, including materials used and vertical heights.

Examples of building sections can be seen in Figures 6.13A and B. Figure 6.14A represents a section through a staircase drawn to a 3/8 inch = 1 foot, 0 inches scale. Several different sections may be incorporated into the drawings. Sections taken from a plan view are called cross-sections; those taken from an elevation are referred to as longitudinal or simply wall sections. Figure 6.14B shows a typical wall section. This type of section is commonly drawn at a scale of 3/4 inch = 1 foot, 0 inches. It is normally located in the structural division and provides information that is necessary to understand the structural arrangement, construction methods, and material composition of the walls of the building. Using sections in conjunction with floor plans and elevations allows the reader to get a better understanding of the project and how it is put together.

Sections are used as needed in each of the main divisions of construction drawings to show the types of construction required, the types and locations of materials used, and the method of assembling the building parts. Although they may be used in each of the divisions, the most common are the architectural and structural divisions. All sections are important to those responsible for constructing a building.
