Computer Aided Design (CAD)
CAD is the use of computer technology to aid in the design and particularly the drafting (technical drawing and engineering drawing) of a part or product.
There are basically two different types of CAD design. One involves three dimensional (3D) representations or “virtual prototypes” and the other is the two dimensional (2D) layout drawings of the part. During the design process it is common to create the 3D models and, if needed, convert the 3D model over to 2D drawings. However, with the advent of CAM and CNC systems, it is becoming increasingly popular to forgo the 2D drawings and program machining straight from the 3D CAD model.
Modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out. Some CAD software is capable of dynamic mathematic modeling.
CAD is used in the design of tools and machinery used in the manufacture of components, and in the drafting and design of all types of buildings. CAD is primarily used for detailed engineering of 3D models and/or 2D drawings of physical components. However it is also used throughout the engineering process, from conceptual design and layout of products, through strength and dynamic analysis of assemblies, to definition of manufacturing methods of components.
CAD has become an especially important technology within the scope of computer-aided technologies, with benefits such as lower product development costs and a greatly shortened design cycle.
