The Aesthedes was a computer graphics or computer-aided design (CAD) system designed and developed in the 1970s and 1980s by Claessens Product Consultants (now Cartils) in Hilversum, Netherlands. The Aesthedes was introduced to the market in 1984 by D.P.G. Claessens (1922–2019) who, after studying monumental art at the State Academy of Art in ...
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.

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).
CADAM (computer-augmented design and manufacturing) is CAD-related software that was developed by Lockheed. [1] CADAM was originally written for IBM mainframes and later ported to UNIX workstations, including the IBM RT PC. A variant of CADAM called Micro CADAM was also developed for PCs under DOS.
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 ...
