What is a sectional view?

A sectional view is a specific type of technical drawing that provides a cross section of an object, illustrating what the interior looks like when a "slice" has been made through it. This allows viewers to see the internal features and dimensions of objects that are not visible in exterior views.

In engineering and architectural drawings, sectional views are essential for conveying complex details, such as the arrangement of components inside machinery or the layout of spaces within a building. By cutting through an object and displaying one side of the slice, sectional views help clarify how different parts fit together and interact, providing vital information for design, manufacturing, and construction processes.

The other options describe views that do not aim to reveal internal structures. A view from an angle showcases an object's exterior without detailing inner components, while a type of two-dimensional representation may refer generally to various kinds of drawings but doesn’t specifically capture the essence of what a section view does. A perspective view represents an object in three dimensions and emphasizes depth, which is also not the primary purpose of a sectional view.
