Technical illustration is a term that refers to the creation of images or diagrams that communicate technical information. However, the term technical illustration is often used interchangeably with other terms, such as technical visualization, technical drawing, technical graphics, or technical diagramming. These synonyms convey the same idea, but they may emphasize different aspects of the technical illustration process. Technical visualization, for instance, implies a focus on the visual presentation of technical concepts, while technical drawing emphasizes the technical precision and accuracy of the illustration. Similarly, technical graphics and technical diagramming convey a sense of creating visual representations of complex data or processes.
