Cad History Bypramit CAD HISTORY CAD HISTORY BY PRAMIT :-- Some time ago, CAD was created. Then there was gaming. It was good. Now it is today. There is probably some gaming going on today. If there is, it is good. A very brief history of CAD development is listed 1. 1940s - First digital computer developed 2. 1950s - Commercial computers become available 3. 1955 - CRTs begin being used in military projects 4. 1957 - APT II (Automatic Programmed Tool) developed for generating NC control. Automated NC used in industry. 5. 1959 - Stromberk Carlson develops a system to interpret graphics on tape, then output them to a screen, or print on special paper 6. 1963 - Ivan Sutherland presents a paper on "Sketchpad" which allows interactive graphics 7. 1965 - Lockheed introduces a CAD/CAM system, and a FEM system. McDonnell introduces CADD 8. 1966 - Business world sees Wall Street Journal title "Electronic Sketching; Engineers Focus on Screen to Design Visually via Computer; Keyboard Enlarges, Rotates `Drawings'; Lockheed, GM Enthusiastic About Uses" 9. 1971 - David Prince writes first book on computer graphics 10. 1975 - ICAM (Integrated Computer Aided Manufacturing) project is begun by US Airforce 11. 1976 - Color raster graphics technology begins to develop. 12. 1979 - Development of IGES begins 13. 1980 - Introduction of PCs revolutionizes all markets 14. 1980s - Solid Modeling on UNIX 15. 1990s - Solid Modeling on low end systems 26 years ago, nearly every drawing produced in the world was done with pencil or ink on paper. Minor changes meant erasing and redrawing while major changes often meant recreating the drawing from the scratch. If a change to one drawing affected other documents you were dependent upon having someone manually recognize the need to make the changes to the other drawings and to do so. CAD has fundamentally changed the way design is done. The first graphic system was in mid 1950 the US Air Force's SAGE (Semi Automatic Ground Environment) air defense system. The system was developed at Massachusetts Institute of Technology's Lincoln Laboratory. The system involved the use of CTR displays to show computer-processed radar data and other information. Dr. Patrick J. Hanratty known as "the Father of CADD/CAM" for his pioneering contributions to the field of computer-aided design and manufacturing, developed in 1957 PRONTO, the first commercial numerical-control programming system. In 1959 the CalComp company is founded. In 1960, Ivan Sutherland used TX-2 computer produced at MIT's Lincoln Laboratory to produce a project called SKETCHPAD, which is considered the first step to CAD industry. Bill Barnes established in his garage in Denver on 15 January 1962, Auto-trol and manufactureed the first product, a digitizer. Mr. Barnes named the company Auto-trol as a shortened version of automated control, which he had given to a product he developed in the 1950s. Parallel projects were developed at ITEK and General Motors. The ITEK project was called The Electronic Drafting Machine and used PDP-1 computer from Digital Equipment Corp., a vector -refresh display and a large disk memory device used to refresh the graphic display. Inputs commands were done with an electronic light pen. While at General Motors Research Laboratories in the 1960s, Dr. Hanratty was a co-designer of DAC (Design Automated by Computer), the first production interactive graphics manufacturing system. In 1960 McDonnell Douglas Automation Company (McAuto) founded. It will play a major role on CAD developments with the introduction of CADD program. The first Computer-Aided Design programs used simple algorithms to display patterns of lines at first in two dimensions, and then in 3-D. Early work in this direction had been produced by Prof. Charles Eastman at Carnegie-Mellon University, the Building Description System is a library of several hundred thousands architectural elements, which can be assembled and drawn on screen into a complete design concept. In 1962, SLS Environectics in Chicago began development of the Man-Mac machine, intended to draft plans for interior office space. In mid 1960 large computers characterized the period, vector display terminals and software development done in assembly language. The only significant attempt to create a commercially CAD system was Control Data Corporation's Digigraphics division, a successor to the previously mentioned ITEK. The system costs half million dollars and were sold in few units. In March 1965 Donald Welbourn heard a lecture to the Engineering Society by Strachey of the Mathematical Laboratory (now the Department of Computer Science) on the early work at MIT on Computer Aided Design (CAD). He was so fascinated by this that the following morning he caught the Head of the Cambridge University Engineering Department, Prof. J.F.Baker (later the Lord Baker of Trumpington) in the tea- room, told him about it, and said that we must get started in this field. Baker was enthusiastic, and by the end of the year, the Science Research Council had awarded Baker and Welbourn a grant of £65,000 with which to start work on CAD. Initially work was done on the PDP11 graphics computer and a joint team was formed under the leadership of C.A.Lang. The first research student was A.R.Forrest, who tackled the problem of how to define the blended intersection of two cylinders. The conceptual breakthrough of defining objects in terms of 3D reference lines, analogous to the draughtsman's centre line, together with cross-sections normal to them, was produced by S.Matthews, seconded by the Ford Motor Co. 1967 Dr. Jason R Lemon founds SDRC in Cincinnati. In 1968 Donald Welbourn, now the Director in Industrial Co-Operation at Cambridge University, had the vision to see the possibility of using computers to assist pattern makers to solve the problems of modelling difficult 3D shapes. Today we take for granted 3D modelling, in 1968 only crude 2D drawing systems were available using terminals linked to large main frame computers. Initial work was sponsored by Ford but finding money to support the development was a constant problem for Donald Welbourn. Only six years later he managed to obtain sponsorship from Control Data in Germany, and Delta Engineering Group. Control Data offered DUCT initially as a bureau services, especially to two of its largest German customers Volkswagen and Daimler Benz. David Evans and Ivan Sutherland founded in 1968 Evans and Sutherland. Dr. Hanratty founded United Computing in 1969. In the same year MAGI company is founded and releases Syntha Vision considered by many to be the first commercial solid modeler program. In 1969 were founding Computervision and Applicon companies. Computervision was created to produce systems for production drafting and in the same year it sold the first commercial CAD system to Xerox. Several other companies began to offer automated design/drafting systems in early 70s. Applicon was more a research-oriented company. In the mid 80s it was acquired by Schlumberger and then merged with MDSI which Schlumberger had acquired earlier. Calma was originally a manufacturer of digitizer used in mapping and integrated circuit manufacturing, and starts to move to the graphic industry at the same time. In mid 80s Calma was acquired by General Electric and then sold to Prime Computer. In 1973, the Hillman Trust purchased Auto-trol. That same year, Auto-trol emerged as a pioneer in the fledgling CAD industry by announcing Auto-Draft, one of the first turnkey graphics systems available. There was also a significant amount of internal development at major automotive and aerospace firms like General Motors, Ford, Chrysler and Lockheed, which work hard, on CADAM. In 1970 M&S Computing founded (later becomes Intergraph). At the beggining it was a consulting firm that supported government agencies in using digital technology. Among these technologies were application-oriented user interfaces that communicated with users in the language of their applications, rather than in programming terminology. The first Intergraph computer graphics system to apply these innovative computing concepts was used by the federal government for designing printed circuit boards. Meanwhile, in 1971, Donald Welbourn had become Director in Industrial Co-operation and Director of the Wolfson Cambridge Industrial Unit. He persuaded the Pye Foundation to support T.H.Gossling, a member of the Unit, in developing DUCT. Control Data had also become interested in the work, seeing it as a front end for creating Finite Element meshes. As a result of this industrial support, Welbourn, had been able in 1974 to get a grant from it for Dr.R.B.Morris and Dr.J.Matthewman to continue developing DUCT. The Science Research Council had said that this work was no longer research, while industry was saying that a lot more development was required. Faced with a potential disaster vis-à-vis the DTI, Welbourn took the direction of the work back into his own hands. and started systematically to test the programs, and the instruction manuals. This resulted in a quality of handbook which was partly responsible for VW and Daimler-Benz taking licenses for DUCT, since they said that they had never seen such clear instructions produced by any firm, let alone by a university. Welbourn never did any of the programming in connection with the work, but made it his job to set targets for what needed to be done, to get money and to get able staff to do the work. In the early stages of the work, up to the oil crisis of 1973, he had got a dozen or so firms to second men to work with the team in Cambridge, thus enabling the firms to get experience of CAD without having to find the capital for a dedicated computer. MCS was founded in 1971 by Dr.

  • CAD Software History, 1960S
    History CAD software started its migration out of research and into commercial use in the 1970s. Just as in the late 1960s most CAD software continued to be developed by internal groups at large automotive and aerospace manufacturers, often working in conjunction with university research groups. Throughout the decade automotive manufacturers such as: Ford (PDGS), General Motors (CADANCE), Mercedes-Benz (SYRCO), Nissan (CAD-I released in 1977) and Toyota (TINCA released in 1973 by Hiromi Araki's team, CADETT in 1979 also by Hiromi Araki) and aerospace manufacturers such as: Lockheed (CADAM), McDonnell-Douglas (CADD) and Northrop (NCAD, which is still in limited use today), all had large internal CAD software development groups working on proprietary programs. Some of the mathematical description work on curves was developed in the early 1940s by Robert Issac Newton from Pawtucket, Rhode Island. CAD software uses either vector based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. CAD is used in the design of tools and machinery and in the drafting and design of all types of buildings, from small residential types (houses) to the largest commercial and industrial structures (hospitals and factories). CAD is mainly used for detailed engineering of 3D models and/or 2D drawings of physical components. CAD stand for computer-aided design. Architects, drafters, engineers, and artists use CAD software to create plans and construction drawings. Computer Aided Design (CAD) is a form of design in which people work with computers to create ideas, models, and prototypes Most CAD software programs were still 2D replacements for drafting, with the main benefits to manufacturers being: i) reduced drawing errors, and, ii) increased reusability of drawings.

" ABSTRACT The research studies and experimental investigations reported are addressed to the problem of developing more efficient means by which the physical scientist might intimately control the complex data processing operations involved in the analysis and meaningful interpre- tation of large volumes of sensor data from scientific satellites. Areas of computer graphics technology in which pioneering efforts might prove fruitful are defined and approaches conceived. The results of pilot tests to evaluate proposed techniques from a human factors viewpoint are given. Specific techniques include information transfer via uncommon display media (full color; flicker; animation) and approaches to facilitate the use of a single input device as the means of processing control. Specifications are developed for an advanced hardware-software system for manipulating and displaying large volumes of data. A man- computer communication station design is recommended which permits finger pointing as a means of input and peripheral equipment to service the display and input devices.
