Why do architects use section views?
Architectural drawings use section views to reveal the interior details of walls, ceilings, floors, and other elements of the building structure. Sectional drawings are multi-view technical drawings that contain special views of a part or parts, which reveal interior features.
Section complex assemblies and parts is important to see detail in Engineering Drawing. Thus some methods of sectioning is discussed.

- Cutting Plane. A surface cut by the saw in the drawing above is a cutting plane. Actually, it is an imaginary cutting plane taken through the object, since the object is imagined as being cut through at a desired location.
- Cutting Plane Line. A cutting plane is represented on a drawing by a cutting plane line. This is a heavy long-short-short-long kind of line terminated with arrows.
- Section Lining. The lines in the figure above, which look like saw marks, are called section lining. They are found on most sectional views, and indicate the surface which has been exposed by the cutting plane.
- Full Sections. When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. 7 illustrates a full section.
A Section or cross section is a view generated from a part or assembly on a cutting plane or multiple cutting planes that reveals the outlines on the inside or assembly fits. Sections normally comprise of two parts, firstly the Section Cut indicator with identification.
This section will cover the different types of section views, corresponding technical vocabulary, and help you determine which section view would best communicate important aspects of an object or assembly to others.
