A sectional view in a technical drawing serves to represent internal features of an object or assembly that are not visible from the exterior. By creating a slice through the material, designers can reveal the arrangement, shape, and relations of internal structures, components, and materials. This view is particularly useful for complex parts where understanding the internal layout is critical for both manufacturing and assembly processes.

This technique allows engineers, architects, and manufacturers to communicate intricate details that are essential for accurate interpretation and production of the item. It provides insights into the design that could not be achieved by external views alone, making it an essential tool in technical drawings.

In contrast, aspects like surface finishes, dimensions, or material specifications are typically conveyed through different means like annotations, labels, or separate notes rather than through sectional views.
