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. [12]
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.
Between the mid-1940s and 1950s, various developments were made in computer software.Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952).
Certain efficiencies were gained by careful design; for example, the memory page size, network packet, and disk sector were all 1K byte in size. With this arrangement, a page fault could take place across the network as well as on the individual computer and Aegis file system was a single system of memory mapped files across the entire network ...
DGN (design) is the name used for CAD file formats supported by Bentley Systems, MicroStation and Intergraph's Interactive Graphics Design System (IGDS) CAD programs. [1] The DGN format is used in construction projects, including buildings, highways, bridges, process plants, shipbuilding. DGN is a competing format to Autodesk's DWG. [1]
DDM (short for "Design, Drafting, Manufacturing") was a 3-dimensional wireframe computer-aided design application. In the mid-1980s, it was one of the top ten selling CAD packages on the market. By 2006, DDM continued to be supported by Parametric Technology Corporation as "Dimension III".
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing , while subtractive manufacturing may also be referred to as machining , [ 1 ] and many other technologies can be used to ...
Creo Parametric, formerly known, together with Creo Elements/Pro, as Pro/Engineer (commonly referred to as Pro E) and Wildfire, is a solid modeling or computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), and associative 3D modeling application, to run on Microsoft Windows.
