What characteristic does a sectional view prominently display?

A sectional view is a type of drawing that provides a detailed representation of an object's internal features by cutting through the object and showing what lies inside. This allows viewers to see the arrangement of parts, materials, and components that are not visible from the outside. The primary purpose of a sectional view is to communicate the internal structure clearly, making it easier to understand complex geometries or systems without the interference of external details.

The use of sectional views is prevalent in engineering and architectural designs, where understanding the internal layout is crucial for assembly, maintenance, and functionality. This method effectively illustrates how different parts interact and fit together within the assembly, providing insights into the design that cannot be inferred from exterior views alone.

In contrast, aspects such as color distinction, surface texture, and external dimensions are typically represented in other types of views or drawings and do not capture the intricate internal arrangements that a sectional view is specifically designed to showcase.
