Drafting Standards

Section drawings are shown as cut through solid elements and spaces (voids) within an object or building. To graphically represent these, certain accepted techniques are often employed. For example, solid materials cut through in the section slice are pouched with standard material designations, such as wood, brick, concrete, and so forth. Some fairly common material designations are listed in the Appendix. Many offices use these, but variations on these graphic standards also occur. Legends or keys are used in the drawings to explain what the material designations stand for. The lines or outlines around these sliced materials are drawn with heavy thick lines to accent the cut. To differentiate these materials from adjacent construction or objects seen beyond the cut plane, lighter and thinner lines are used (Figure 8-7).
