![]() ![]() Its major advance over CADAM was real approach to 3D modelling. Nemetschek started selling its ''Programm system Statik 97/77'' for civil engeneering.Īvions Marcel Dassault started developing the forerunner of CATIA named CATI. United Computing, and their UNI-GRAPHICS was acquired by McDonnell Douglas ( McAuto). MCS introduced AD-2000, a design and manufacturing system for the first 32-bit computers. This CAD was the direct successor of the ADAM The French aerospace company, Avions Marcel Dassault (AMD), purchased a source-code license of CADAM from Lockheed and three years later began developing a 3D CAD software program named CATIA (Computer Aided Three Dimensional Interactive Application). The Hillman Trust purchased Auto-tro and announced Auto-Draft, one of the first turnkey graphic systems available. United Computing introduced UNI-GRAPHICS system. It provided basic 2D modeling & drafting functionality and supported 14 layers. The user interface of ADAM was already controlled by menu. MCS company released its first CAD named ADAM (Automated Drafting and Machining), it ran on 16-bit computers, and it was one of the first commercially available mechanical design packages. 3D models in this system were solid models similar to models used by later 3D CAD software. The first 3D solid modeling program SynthaVision from MAGI (Mathematics Application Group, Inc.) was released - not as CAD software but as a program for performing 3D analysis of nuclear radiation exposure. M&S Computing was founded (later becomes Intergraph) – At the beginning it was a consulting firm that supported government agencies in using digital technology. More companies introduced their first commercial CADs at the end of the 60s. It is necessary to mention at least Applicon, Auto-trol, Computervision (sold its first commercial CAD system to Xerox), Evans & Sutherland, MAGI (released commercial 3D CAD Syntha Vision), McAuto, SDRC and United Computing (nowadays known as UGS). Georg Nemetschek company started to develop software, initially only for in-house use 1969 The program only ran on very expensive IBM mainframe computers.įord Corporation introduced its CAD named PDGS 1968 McDonnell Douglas Automation Company ( McAuto) introduced its patented CAD program named CADD - originally developed for solving different geometry problems. The Lockheed Corporation introduced its CAD/CAM system, and FEM system named CADAM (Computer Augmented Drafting and Manufacturing). Although DAC was said to be incredibly useful at its time, GM discarded the system when it upgraded its hardware. It was the first CAD/CAM system using interactive graphics (enabled to type car description, rotation, and viewing from different angles). Hanratty co-designed CAD system, named DAC (Design Automated by Computer) at General Motors Research Laboratories. It was priced at $500,000 per unit (only a very few units were ever sold).ĭr. Input commands were done with an electronic light pen and a large disk memory device used to refresh the graphic display.Ĭonsequently - Digigraphics division of Control Data Corporation released the first commercially available CAD software system - which was a successor to ITEK's earlier CAD software. ITEK company developed CAD software research system named "The Electronic Drafting Machine" for PDP-1 computer. 20 years later it started to produce well-known AEC system named Allplan. Georg Nemetschek founded his company as a civil engineering office in this year. But still it was not commercial product yet. This is considered to be the first step to CAD industry. Ivan Sutherland (MIT‘s Lincoln Laboratory) developed the program named SKETCHPAD on the TX-2 computer and demonstrated the basic principles feasibility of computer aided engineering drawing. John McCarthy invented the LISP (programming language used in AutoCAD ® until now) 1963 Stromberk Carlson developed a system which interpreted graphics on some kind of tape and output these graphics on screen or printout graphics on special papers. Hanratty (most often referred to as "the father of CAD CAM") developed PRONTO – the first commercial numerical control programming CAM system. ![]()
