A type of view known as a section view is used to help show interior details. A section view is created by passing an imaginary cutting plane through the object and removing the part near- est to the observer. This allows a direct view of the interior details. Section views are also called sectional views, cross sections, or simply sections. See Figure 6‑1. The standard practices for sectional views are covered in ASME Y14.3, formerly titled Multiview and Sectional View Drawings, but now titled Orthographic and Pictorial Views.
