What is the purpose of the 'Section View' in the drawing environment?

The purpose of the 'Section View' in the drawing environment is to show internal features of a part or assembly. This view allows designers and engineers to visualize and communicate how different components interact within the overall structure, revealing details that may not be visible in standard views. By slicing through the model along a specified plane, a section view provides a clear representation of internal geometry, such as features, profiles, and the arrangement of parts, which is critical for understanding the function, assembly, and manufacturing processes of the design.

This capability is essential for engineers and fabricators when assessing how parts fit together and ensuring that internal components meet design specifications. While showing a full assembly from a distance could provide an overview, and creating a detailed 3D view might aid in visualization, neither adequately reveals the complexity of internal structures like a section view does. Modifying model dimensions is related to the design process but is not the primary function of the section view. Thus, the use of section views is integral in accurately conveying the intricacies of a design to stakeholders involved in the production and analysis of the part or assembly.
