What characteristic does a sectional view depict in an orthographic drawing?

A sectional view in an orthographic drawing is specifically used to depict internal or hidden features of an object. This type of view involves slicing through the object to reveal its internal structure, allowing for a clear understanding of components that are not visible in external views. This is particularly useful in complex designs, where understanding how parts fit together inside an assembly is crucial for accurate construction, maintenance, or modification.

By using sectional views, a reader can visualize the relationships and configurations of internal features such as cavities, reinforcements, and other elements that contribute to the overall integrity and functionality of the component. This contrasts with other views in orthographic drawings, which primarily show the external features, true shape of surfaces, or relative locations of parts without providing insight into internal configurations.
