Sections are usually used to clarify the building design and construction process. Transverse and longitudinal sections are usually drawn at the same scale as the floor plan and show views of cross sections cut by vertical planes. A floor plan or foundation plan, cut by a horizontal plane, is a section as well as a plan view, but it is seldom called a section. They offer a view through a part of the structure not found on other drawings. To show as much construction information as possible, it is not uncommon for staggered (offset) cutting planes to be used in developing sections. To reduce the time and effort required for drafting and to simplify the construction drawings, it is common practice to use typical sections where exact duplications would otherwise occur.
