What does a broken-out section in a drawing reveal?

A broken-out section in a drawing is specifically designed to showcase a part of an object that is not easily visible from the outside. This technique involves removing a portion of the outer layer to reveal the internal features, providing a detailed view of what lies within that section. This is particularly useful in engineering and design contexts where understanding the internal structure is crucial for assessing functionality, assembly, or repair.

By highlighting interior features, a broken-out section allows designers, engineers, or builders to understand complex geometries, connections, and components that are otherwise obscured. This level of detail supports better communication and understanding of the design intent and ensures that all stakeholders have access to the necessary information for effective collaboration and execution.

The other choices pertain to different aspects of drawing features. A cross-section focuses on slicing through an object to show dimensions and relationships across different planes. Overall dimensions provide a vital summary of size but do not convey internal characteristics. The alignment of parts deals more with assembly and positional relationships rather than revealing internal structures.
