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.

CAD/CAM systems use primarily two types of surfaces: Regular (or canonical) surfaces include surfaces of revolution such as cylinders, cones, spheres, and tori, and ruled surfaces (linear in one direction) such as surfaces of extrusion. Freeform surfaces (usually NURBS) allow more complex shapes to be represented via freeform surface modeling. [1]
] CAM is a subsequent computer-aided process after computer-aided design (CAD) and sometimes computer-aided engineering (CAE), as the model generated in CAD and verified in CAE can be input into CAM software, which then controls the machine tool. CAM is used in many schools alongside CAD to create objects.
Mastercam is CNC Software's main product. It started as a 2D CAM system with CAD tools that let machinists design virtual parts on a computer screen and also guided computer numerical controlled (CNC) machine tools in the manufacture of parts. Mastercam has been ranked by CIMdata Inc. as the most widely used CAM package in the world since 1994. [2]

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.
WorkNC Wire EDM is a CAD/CAM software for Wire Electrical discharge machining. Dialog boxes guide the user through the system. Functions within WorkNC Wire EDM allow the extraction of cross sections, ready for 2- or 4-axis cutting. Alternatively, the 3D surfaces of the CAD model can be used directly.
Creo Parametric (formerly Pro/Engineer), PTC's parametric, integrated 3D CAD/CAM/CAE solution, is used by manufacturers for mechanical engineering, design and manufacturing. Pro/Engineer was the industry's first rule-based constraint (sometimes called "parametric" or "variational") 3D CAD modeling system. [ 3 ]
