Which type of view is represented by the highlighted area in a technical drawing?

The highlighted area in the technical drawing represents a sectional view. A sectional view is used to illustrate the internal features of an object as if it has been cut along a specific plane. This type of view helps in understanding complex geometries that are not visible in the exterior views, allowing for a detailed look at the internal structure and components.

In sectional views, the part that is 'cut' is typically shown in a thicker, darker line to emphasize the area of interest. This visual representation is crucial in engineering and architectural drawings for conveying dimensions, materials, and assembly details that would otherwise be hidden in other views.

Understanding sectional views is essential for interpreting and designing technical drawings effectively, as they provide crucial insights into an object's design that other views may not convey adequately.
