It's not duct tape or gaffer's tape, but tape is as essential to a car designer as a good imagination. Sometimes car design teams will use tape at the most basic level.
For vehicle designers, tape has its own language. Ford designers often use tape to communicate with each other or with engineers – even with modern 3D digital imaging, automakers still rely on clay to sculpt and mold vehicles as the design develops.
Tape brings a measure of precision to a process that results in a life-size 3D visual that cannot be duplicated on a computer screen, complementing the digital process. Tape is a perfect example of how old and new technology intersect in creating and designing modern vehicles. It is a bit of an unexplored element to the design process.
