What is the purpose of auxiliary views in technical drawing?

Auxiliary views in technical drawing are primarily utilized to depict the true shape and size of inclined features or surfaces that cannot be accurately represented in the standard front, top, or side views. These views are constructed by projecting lines from the existing views onto a plane that is perpendicular to the inclined feature, allowing the drafter to visualize and clarify the specifics of that particular surface in a way that is not achievable through traditional orthographic projections.

This specialized view is crucial in complex designs where details may be obscured or distorted in the standard views, thereby ensuring that all aspects of the design are clearly communicated and interpreted correctly. Achieving the true shape of inclined features is essential for accurate manufacturing or assembly, which underscores the importance of auxiliary views in technical drawing.
