Types of Section Drawings

Sections can be drawn of a total building, interior space, or object. These are referred to as full sections. However, if only an isolated area needs to be illustrated, a partial section can also be drawn. Sections can be cut in a variety of ways to show more detailed information. A section might be cut all the way through a building (called a building section), or only through a wall (wall section).

Both may be needed, because the small scale and complexity of a building section generally means the materials and details related to the walls cannot be drawn there. A symbol on the building section shown in Figure 8-4 marks the wall area to be enlarged. The wall section (Figure 8-5) is drawn to accurately show the many details and materials that are needed in the assembly.

In addition to building and wall sections, there may also be a need to draw a section through built-in or custom components within a space, such as shelving, reception desks, credenzas, bars, display cases, cabinets, and counters. Figure 8-6 shows a built-in cabinet section. These types of sections are discussed in more detail in Chapter 9.

CABINET SECTION

In interior construction drawings, sometimes the terms section and detail are interchanged, thus causing some confusion. Section cuts through small portions of construction or objects, for example, are often referred to as details. But details are not always drawn in section. They may also include enlarged portions of the floor plan or elevation.

The scale of section drawings may range from y%" to 3" (3.17 mm to 76 mm), depending upon the size of the drawing paper, the size of the building (or component), and the desired features to be shown. The specific information a section shows may vary, depending on whether it is a design or construction drawing. Construction drawings show only the items or components of a space that are built in or attached to the structure. Movable furniture is not shown in this type of drawing.
