CAD / Computer Aided Design
Computer-aided design (CAD) is the use of computer programs to create two- or three-dimensional (2D or 3D) graphical representations of physical objects. CAD software is used by architects, engineers, drafters, artists, and others to create precision drawings or technical illustrations. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models.
Benefits of CAD:
The benefits of CAD include lower product development costs, increased productivity, improved product quality and faster time-to-market.
1. Better visualization of the final product, sub-assemblies and constituent parts in a CAD system speeds the design process.
2. CAD software offers greater accuracy, so errors are reduced.
3. A CAD system provides easier, more robust documentation of the design, including geometries and dimensions, bills of materials, etc.
4. CAD software offers easy re-use of design data and best practices.
