What is the main purpose of section views in a print?

The primary purpose of section views in a technical drawing is to provide cross-section illustrations of the part's interior. This allows for a clear understanding of complex internal features that might not be visible from the exterior view. By cutting away certain portions of the object in the drawing, section views reveal the arrangement of components inside the part, helping engineers and manufacturers visualize how the part is constructed and how different elements relate to each other. This is particularly important in applications where internal geometry affects functionality, such as in mechanical assemblies, complex machined parts, or molded components.

The other options focus on aspects that section views do not primarily address. For example, showing external features is typically covered by front, top, or side views of the part. Displaying the material used for the part can be indicated through annotations or specifications but is not a direct purpose of section views. Indicating the manufacturer's logo pertains to branding and identification, which is not the focus of section views. Thus, the role of section views is specifically to enhance understanding of a part’s internal construction and functional details.
