What does it mean to annotate a drawing?

Annotating a drawing involves adding explanatory notes or symbols to enhance understanding and provide clarity on the details depicted in the drawing. This practice is essential in engineering and design because it ensures that anyone reviewing the drawing can easily grasp its intent, specifications, and any relevant instructions or information. Annotations can include dimensions, material specifications, process notes, or any additional information that aids in interpreting the drawing accurately. This clarity is crucial for effective communication among engineers, designers, and stakeholders involved in a project.
