What is the term for cutting away part of an object to show an area or hidden part?

The term for cutting away part of an object to reveal an internal area or a hidden part is known as a section view. This technique is commonly used in technical drawings and engineering plans to provide a clear representation of the internal features of an object, allowing for better understanding of its construction and components. Section views help in visualizing how different parts of an assembly interact with one another, particularly in areas that are not visible from the exterior.

In contrast, a detail view focuses on a specific area of a drawing, magnifying that section to provide further detail without necessarily showing internal structures. An exploded view displays the components of an object separated along their assembly lines, making it easier to understand how they fit together, but it does not cut away material. A combined view typically refers to a drawing that includes multiple perspectives or types of views, highlighting different aspects without cutting through the object. Thus, the clarity and utility of a section view in understanding internal features make it the correct choice for this question.
