3D rendering of a car in CAD software with boundary representation. Also important to the development of CAD was the development in the late 1980s and early 1990s of B-rep solid modeling kernels (engines for manipulating geometrically and topologically consistent 3D objects), Parasolid (ShapeData), and ACIS (Spatial Technology Inc.). These ...
Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.
One goal of CAD is to allow quicker iterations in the design process; [9] another is to enable smoothly transitioning to the CAM stage. [10] Although manually created drawings historically facilitated "a designer's goal of displaying an idea," [11] it did not result in a machine-readable result that could be modified and subsequently be used to directly build a prototype.

Patrick J. Hanratty was an American computer scientist and businessperson, commonly referred to as the "Father of CAD/CAM" [1] [2] [3] —computer-aided design and computer-aided manufacturing. Up to 2013, he was president and CEO of Manufacturing and Consulting Services (MCS) of Scottsdale, Arizona, a company he founded.

Currently, the main distinction which causes one to speak of CAAD rather than CAD lies in the domain knowledge (architecture-specific objects, techniques, data, and process support) embedded in the system. A CAAD system differs from other CAD systems in two respects: It has an explicit object database of building parts and construction knowledge.
However, automation via cams is fundamentally different from numerical control because it cannot be abstractly programmed. Cams can encode information, but getting the information from the abstract level (engineering drawing, CAD model, or other design intent) into the cam is a manual process that requires machining or filing.
CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining [1] [2] [3] is the use of software to control machine tools in the manufacturing of work pieces.
