How are processes and treatments indicated on drawings?

Processes and treatments are typically indicated on drawings through standardized symbols, annotations, and legends that convey specific information. These may include hatching patterns, color coding, or notations that specify the type of treatment or process to be applied. For example, in architectural or engineering drawings, different line types may represent various materials or processes, while notes or callouts provide additional details. Clarity and consistency in these indicators are essential for effective communication among stakeholders.
