Why use special software for technical illustration?
Technical illustrators need specialized tools to properly illustrate the workings of a device or machine for audiences that include engineers, technicians and/or users with no technical background. A technical illustration is flexible for adding or omitting information. Unlike a technical drawing, a technical illustration can omit elements to only include details relevant to its purpose. It can also be updated to include tools and elements that were not modelled or depicted during the construction process.
