What is the function of an auxiliary view in technical drawings?

The function of an auxiliary view in technical drawings is specifically to provide a representation of features that are located on an inclined surface in their true size and shape. Traditional orthographic views may not accurately depict these features due to the angles involved, which can distort their dimensions when projected onto the typical front, top, or side views. By using an auxiliary view, engineers and designers can create an accurate depiction of these inclined surfaces, enhancing clarity and ensuring that all specifications can be understood correctly.

This clarification is crucial in fields such as manufacturing and construction, where precise dimensions are vital for creating components that fit together accurately. An auxiliary view allows for a more comprehensive understanding of the geometry of a part, facilitating better communication among team members and stakeholders in the engineering process.
