CAD: Computer-Aided Design

Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design.

CAD stands for Computer-Aided Design is software used by engineers, architects, artists, drafters to make a technical illustration in two-dimensional (2D) and three-dimensional (3D). It is a combination of hardware and software that makes engineer design everything. It provides the facility to view a design from any angle and to zoom in or out for closure or a distant look respectively. Moreover, when a designer makes a change in the design, all the values depending on that change changes automatically according to that.

Earlier until the mid-1980s, CAD systems were differently constructed computers but now you can purchase CAD software and can run on your personnel desktop.

Usage of CAD

  • To design the layout of physical components of manufactured products using 2D or 3D.
  • Used in designing space vehicles, aircraft, missiles and satellites.
  • Architectures use CAD for building purposes. They use 2D for the floor plans and 3d for the schematics of houses.
  • Used in designing auto components such as tires, engines, etc.
  • Used in cartography to design climate, road and topographic maps.
