Technical illustrations are detailed drawings or diagrams that visually represent complex information, often used in fields like engineering, architecture, and manufacturing. These illustrations help convey how products work, how systems are assembled, or how processes are executed, making it easier for users to understand intricate concepts. Typically created using software or by hand, technical illustrations can include labels, dimensions, and annotations to clarify specific features. They are commonly found in user manuals, product guides, and educational materials, serving as essential tools for professionals such as engineers, designers, and technicians to communicate ideas effectively.
