Computer-Aided Design (CAD) is the use of computer programs to create two- or three-dimensional (2D or 3D) graphical representations of physical objects.
In product and industrial design, CAD is used mainly for the creation of detailed 3D solid or surface models, or 2D vector-based drawings of physical components. Throughout the engineering process, CAD will be used from conceptual design and layout of products, through strength and dynamic analysis of assemblies, to the definition of manufacturing methods; these enable engineers to interactively and automatically analyze design variants, to find the optimal design for manufacturing while minimizing the use of physical prototypes.
CAD Interoperability is always a concern for organization who works with multiple CAD software files. CAD interoperability improve design reuse, collaboration between internal colleague and external supplier, in return, improve engineering organization effectiveness and productivity.
