Dr. Patrick J. Hanratty (most often referred to as "the father of CAD CAM") developed PRONTO – the first commercial numerical control programming CAM system.
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.
John McCarthy invented the LISP (programming language used in AutoCAD® until now)
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. This is considered to be the first step to CAD industry. But still it was not commercial product yet.
Georg Nemetschek founded his company as a civil engineering office in this year. 20 years later it started to produce well-known AEC system named Allplan.
ITEK company developed CAD software research system named "The Electronic Drafting Machine" for PDP-1 computer. Input commands were done with an electronic light pen and a large disk memory device used to refresh the graphic display.
Consequently - Digigraphics division of Control Data Corporation released the first commercially available CAD software system - which was a successor to ITEK's earlier CAD software. It was priced at $500,000 per unit (only a very few units were ever sold).
Dr. Hanratty co-designed CAD system, named DAC (Design Automated by Computer) at General Motors Research Laboratories. It was the first CAD/CAM system using interactive graphics (enabled to type car description, rotation, and viewing from different angles). Although DAC was said to be incredibly useful at its time, GM discarded the system when it upgraded its hardware..
The Lockheed Corporation introduced its CAD/CAM system, and FEM system named CADAM (Computer Augmented Drafting and Manufacturing).

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).
M&S Computing was founded (later becomes Intergraph) – At the beginning it was a consulting firm that supported government agencies in using digital technology.
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. 3D models in this system were solid models similar to models used by later 3D CAD software.
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. The user interface of ADAM was already controlled by menu.

This decade was the time when the basic CAD features were formed – especially the fundamental geometric algorithms. The computer's price was about $125,000, and the first commercial CAD systems resellers started to be formed.

T&W Systems reprogrammed its software named T-Square for the Apple II computer and introduced it as CADapple
SDRC company announced the first I-DEAS.
Autodesk (initially called Marin Software Partners) was founded by sixteen people in this year by initiative of computer programmer John Walker. The main idea was to create a CAD program for a price of $1000 able to run on PC. One of the objectives was to create a CAD system as open as possible. The first version of AutoCAD was based on a CAD program written in 1981 by Mike Riddle called MicroCAD.
AutoCAD-80 (respectively AutoCAD 1 for PC) was demonstrated for the public in November at the COMDEX trade show for the first time.
At this time DWG and DXF formats were also defined!
Unigraphics was basically still the original MCS ADAM software, although significantly revised by United Computing and subsequently by McAuto. The new software (substantially a new product) after a complete re-architecting was named as Unigraphics II version 1 - and earlier software was now called Unigraphics I.
Adra Systems was founded and soon after that it began releasing its CADRA 2D CAD
Jon Hirschstick (who later started SolidWorks) founded a company called Premise. Their first product was DesignView - simple parametric 2D tool.

AutoCAD R9 was released (only for DOS) - the first version of AutoCAD to require an 80x87 maths processor in computers based on Intel 8086 processors.
The release of AutoCAD R9 was a little surprise.
When Autodesk was asked what happened with versions 3 - 8, Autodesk reputedly replied, that there were really 8 major previous versions. Even if 3-8 versions nobody had ever seen, to call a new version as 3.0 seemed not to be a good idea, and so AutoCAD R9 was released
CATIA Version 3 was released and became the automotive application leader. This version was announced with AEC functionality.
Surfware Inc., shipped the first version of SurfCAM, a CAD/CAM program.
PTC shipped the first version of Pro/ENGINEER. Concept of parametric modeling is quickly followed by other products, such as SolidEdge, SolidWorks, Unigraphics,... etc.
MDM&E/Unigraphics was threatened by Pro/ENGINEER and was forced to react more quickly, and so, the Unigraphics acquired Shape Data (developer of solid modeller Romulus), quickly retired the PADL-2 based UniSolids and in late 1989 introduced solid-modeling CAD software program named UG/Solids based on Parasolid.
Autodesk released AutoSolid and AutoCAD R10 (DOS & MAC), with full 3D capabilities
Spatial Technology developed the first version of ACIS solid modeling kernel. Ron Davidson launched Parasolid as a "de-facto standard" solid modeling kernel. The solid modeling kernel Designbase (released in 1987 by Ricoh) was quickly adopted by many Japanese CAD software vendors and Ricoh began to sell Designbase in the US.
and ...started the war of the "solid modelling kernels" between ACIS, DesignBase and Parasolid which was to continue throughout the following decade.

Microstation v.5, CINEMA 4D version 2 for Amiga and MiniCAD v.5 were introduced.
Softdesk acquired Phoenix (IntelliCAD).
Softdesk and Cyco Software were the largest AutoCAD developers at that time. Cyco Software was kicked out of an AutoCAD conference, because its product (Auto- Manager) competed with one of Autodesk (WorkCenter) - never mind that the AutoManager product was the first, and Autodesk's WorkCenter came later. The falling out with Cyco set off alarm bells at Softdesk. What if Autodesk cuts us off like Cyco? they wondered. Softdesk decided to create a secret team for secret project named IntelliCAD. The team with ten programmers (as a precaution) was located on the other side of the country.

To prevent a monopoly, the Federal Trade Commission ordered Autodesk to divest itself of IntelliCAD, not to buy companies that dealt with IntelliCAD, and did not interfere in employees who left Autodesk and began to work with IntelliCAD. Boomerang Technology for the purpose of acquiring the IntelliCAD was founded. And at the same time - Boomerang assigned and sold all of its rights to the IntelliCADD product to Visio Corporation (originally named ShapeWare).
Visio started to sell IntelliCAD 98 – AutoCADu R14 clone. There were 12.000 licences of IntelliCAD sold for the first three months. The successful sale of their Visio Technical (on its stimulation, the Autodesk later released competitive product Actrix Technical) continued.

PTC assumed rights to VersaCAD from Archway Systems company
Microsoft nearly entered to the CAD market – by Visio acquisition. Visio became the division in Microsoft. Because of the potential risk of judicial anti-trust problems, Microsoft spun off IntelliCAD into a public service organisation (www.intellicad.org) to give away Intellicad for free - and the ITC (IntelliCAD Technology Consorcium) was founded.
Microsoft was aware it would make Autodesk angry (the sixth largest software company at that time) , which started to compete with Microsoft in multi-media software area.
2000 - to yesterday (overview of the main events)
The new versions of old CAD products and also new CADs were released, and their number was already becoming hard to read

Bentley acquired InRoads software from Intergraph (in 2000) and acquired Infrasoft (in 2000) - a developer of AutoCAD and Archicad moduls for general road design (MXROAD) and others. It is assumed that the main reason for the Infrasoft purchase was to sidetrack Autodesk from "civil design".
