The abbreviation CAD stands for "computer-aided design". In concrete terms, working with CAD software means that individual steps in the design process are no longer carried out manually, but are taken over by the computer. With the help of CAD software, steps from concept development to handover to the production department can be completed directly on the computer. Be it in 2D, for example, when creating a city map, and in 3D, as when planning entire building complexes. The design process and technical drawing are simplified across industries through the use of CAD software.
