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.

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 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 '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. Patrick J. Hanratty. Since the day it was founded in 1971, MCS has enjoyed an enviable reputation for technological leadership in mechanical CADD/CAM software. In addition to selling products under its own name, in its early years MCS also supplied the CADD/CAM software used by such companies as McDonnell Douglas (Unigraphics), Computervision (CADDS), AUTOTROL (AD380), and Control Data (CD-2000) as the core of their own products. In fact, industry analysts have estimated that 70% of all the 3-D mechanical CADD/CAM systems available today trace their roots back to MCS's original code.

The company's first product, ADAM (Automated Drafting and Machining), was released in 1972, ran on 16-bit computers, and was one of the first commercially available mechanical design packages.

In 1972 the CUED was able to obtain two 3-axis n/c machine tools with a DTI grant to help the m/c tool industry, thus enabling the work in CAD to be expanded into CAM. One of these, a Hayes milling machine, went onto the firm's stand at the Machine Tool Exhibition at Olympia that Autumn, and thanks to a sterling effort by P.J.Payne, a jug-like object, was cut on the stand. This was probably the first ever public demonstration of 3-D CADCAM at a machine tool exhibition.

1972: The earliest Intergraph (M&S Computing) terminal was designed to create and display graphic information. Composed of unaltered stock parts from various vendors, the terminals consisted of a single-screen Tektronix 4014 display terminal with an attached keyboard and an 11-inch by 11-inch "menu" tablet that provided the operator with a selection of drawing commands.

By the end of 1973 and the beginning of 1974 a number of firms had paid the WCIU to make simple tools for them. These were probably the first industrial tools, other than those for automobile bodies, to be made using CADCAM. They were both programmed by T.H.Gossling, and made in the CUED workshop.

In 1974 the first commercial sale of an M&S system. The system - based on a PDP central processor from Digital Equipment Corporation - ran the first version of Intergraph's original core graphics software, the Interactive Graphics Design System (IGDS), and was used for mapping applications.

Electronic Data System Corporation (EDS) is founded in 1975

A major improvement was the new 19" display terminals from Tektronix in 1975, which allows to display larger drawings than the original 11" units.

In 1975 Avions Marcel Dassault (AMD) purchased CADAM (Computer-Augmented Drafting and Manufacturing) software equipment licenses from Lockheed thus becoming one of the very first CADAM customers.

Early solid modeling software first started showing up in the late 70s. Taking basic geometric objects such a sphere, block, cylinders and wedges and combining them using Boolean operations such a remove a cylinder from a block to create a hole.

In 1976, MCS introduced AD-2000, a design and manufacturing system for the first 32-bit computers.

In 1976 United Computing, developer of the Unigraphics CAD/CAM/CAE system, acquired by Mc Donnell Douglas company. By 1977, Avions Marcel Dassault assigned its engineering team the goal of creating a three- dimensional, interactive program, the forerunner of CATIA (Computer-Aided Three-Dimensional Interactive Application). Its major advance over CADAM was that all-important third dimension. While CADAM automated the existing world of two-dimension engineering, essentially drafting and calculation with roots in descriptive plane geometry, CATIA lifted Dassault engineers into the world of 3-D modeling, removing the possibility of misinterpreting two-dimensional data and generating a host of immediate benefits.

In 1977 a new department called Delta Technical Services was formed at Cambridge University to continue research in CAD, but it remained difficult to justify the technology as computers were slow and expensive and the available software had few automatic features and was difficult to use.

In 1978, Computervision introduced the first CAD terminal using raster display technology. In the late 70s, Computervision made a costly decision to build their own computer system. Once the new 32-bit systems replaced the old systems, Computervision was no more on the first line and switched to Sun Microcomputers. Finally it was acquired by Prime.

In 1978 the Computer Graphics Newsletter, a 2 years old publication, change the owner and will become Computer Graphics World magazine.

In 1979, Auto-trol became the first company to market technical publishing applications to be used to produce the complex technical illustrations needed for service manuals, parts catalogs, and engineering documentation.

In 1979 Boeing, General Electric and NIST develops a neutral file format as a contract from Air Space called IGES (Initial Graphic Exchange Standard). It will become the industry standard format and the most widely accepted format for transferring complex surface information, such as NURBS curves.

At the same time Cymap, an English company, starts developing HVAC and Electrical drawings software. Their major product will be CADLink.

Mike and Tom Lazear who are credited with developing the first PC CAD software in 1979

At the end of 70s a typical CAD system was a 16-bit minicomputer with maximum of 512 Kb memory and 20 to 300 Mb disk storage at a price of 125,000 USD

1980 T&W Systems releases Versa CAD

1980 Matra Datavision founded as part of Lagardene Group and starts producing CAD/CAM software. 1981 Dassault Systems is created.

1981 Computer graphics from Cornell University founded 3D/Eye Inc., a pioneered 3D and graphics technology. 1981 Unigraphics introduced the first solid modeling system, UniSolid. It was based on PADL-2, and was sold as a stand-alone product to Unigraphics. 1982 CATIA Version 1 is announced as an add-on product for 3D design, surface modeling and NC programming. 1982 In 1982 mini computers with much more power at less cost started to appear. This was a major step forward and by 1984 the technology began to be competitive with traditional methods. For many years aircraft had of course been designed using computers, but now it was becoming possible to economically design saucepans and other domestic products with complex 3D shapes using a computer. 1982 Autodesk was founded by sixteen people in April 1982 in California by initiative of John Walker in idea to create a CAD program for a price of $1000 to can run on PC. John Walker has been running Marinchip Systems for two years before. The first version of AutoCAD was based on a CAD program wrote in 1981 by Mike Riddle called MicroCAD, changed later in Interact. 1982 A company called P-CAD released a CAD program called CADplan. Later the product was purchased by CalComp and renamed CADVANCE. 1982 In November at COMDEX trade show in Las Vegas was demonstrated the first CAD program in the world that runs on PC. This was the initial release of AutoCAD and deliveries begun in December. 1983 Unigraphics II introduced to market

1983 Applicon introduces BRAVO! first 32-bit VAX based mechanical design/NC system

1983 The first German and French versions of AutoCAD

1983 The work has started for a new reliable and universal system of transferring data called STEP (Standard for the Exchange of Product model data). STEP can transfer CAD data, to include complete details of product modeling including materials and various design parameters. The first generally available STEP translator was released in 1991 by EDS Unigraphics. 1983 Autodesk ships version 1.2 of AutoCAD in April, version 1.3 in August and version 1.4 in October. 1984 CoCreate Software Inc., was established in 1984 as a division of Hewlett-Packard Company with the charter to expand the scope and focus for development of computer- aided design (CAD) and computer-aided manufacturing (CAM) software products. In 1996, CoCreate became a wholly-owned subsidiary of Hewlett-Packard Co. and expanded its product offerings to include collaboration software solutions. 1984 DUCT development continued at Cambridge together with the small team established at Delta in Birmingham. By 1984 the Birmingham team was larger than that at Cambridge and the unique features of DUCT began to be recognised. It was one of the very few systems developed from the beginning to design and machine products. The equal emphasis on design and machining made it different to its competitors and this was appreciated by the users. Most other systems had developed 2D draughting first, followed by 3D modelling with machining added later. 1984 In 1984, a Hungarian physicist, Gabor Bajor, smuggled two Macs into his country. At the time, ownership of personal computers was illegal under Communist rule. Using Pascal, he and a teenager, Tamas Hajas worked to write a 3D CAD program for the Mac which will be the beginning of Graphsoft Company. 1984 Drafting capabilities are added to CATIA in 1984, enabling it to function independently of CADAM. 1984 The first Autodesk Training Centre

1984 In October AutoCAD version 2 (Release 5) with text improvements, DXFIN and DXFOUT commands, new Inquire commands, Object Snap, named views, Isometric capabilities and new Attribute features.

1985 Keith Bentley founds Bentley Systems, Inc.

MicroStation provides advanced computer-aided design on PC. MicroStation began as a clone of another CAD package. Originally named PseudoStation, the software developed by Bentley Systems allowed users to view IGDS drawings files without needing Intergraph's software. The next version of PseudoStation was renamed MicroStation and added the ability to edit IGDS files. After Intergraph purchased 50% of Bentley Systems, a new version of MicroStation added proprietary extensions to the IGDS and renamed it DNG. 1985 CATIA Version 2 is announced with fully integrated drafting, solid and robotics functions. CATIA becomes the aeronautical applications leader. 1985 The first CAD Camp organized by Autodesk in San Rafael, California.

Release 9 includes as well an Advanced User Interface incorporating a menu bar, pull- down menus, icon menus and dialog boxes. ADS (AutoCAD Development System) was introduced with release 9 for OS/2 and allowed C code to be used instead of ASCII based AutoLISP. To enable C code to access AutoCAD internal data, a set of application programming interfaces (APIs) are supplied with AutoCAD. Internally AutoCAD sees an ADS application exactly the same as a LISP routine.

1988 Shape Data Ltd. acquired by Unigraphics for solids modeling capabilities -- Parasolid -- the production-proven kernel modeling toolkit.
