An engineering sketch is a detailed drawing that visually communicates the design and specifications of an object. It typically includes multiple views (top, front, side) to provide a comprehensive understanding, along with accurate dimensions and tolerances that specify acceptable size limits. The sketch often incorporates standard symbols for materials and processes, as well as different line types to represent features such as edges or hidden parts. Annotations and notes provide additional context, ensuring clarity in communication. Overall, engineering sketches are essential tools in the design and manufacturing process, facilitating collaboration and precision.
