Technical illustration involves the creation of drawings that depict intricate, specialized concepts. These illustrations can represent physical objects or abstract ideas through the use of symbols and annotations. Employing technical illustrations is an effective means to visually convey information, either to complement written content or to elucidate concepts that are challenging to articulate verbally. Technical illustrations find applications in various contexts and publications, including instructional manuals, textbooks, encyclopedias, architectural sketches, engineering blueprints, computer graphics, and websites. They serve as valuable aids for teaching and clarifying technical subjects to the general public, while also facilitating communication among professionals such as scientists and engineers. The level of detail and complexity of a technical drawing is tailored to its intended audience.
