Based on ITEK Control Data Corp., in 1965 the first CAD was marketed with a price of US$500,000. In that year, Professor J. F. Baker, head of the Engineering Department at the University of Cambridge, began research in Europe working with a PDP11 graphics computer. A. R. Forrest performs the first research study with a CAD, performing intersection of two cylinders.

In 1969, Computervision developed the first plotter (plotter) and in the same year an engineering company from Bilbao, Sener") already used it in its program for ship design.[1]​ A year later, companies in the aerospace and automobile world (General Motors, Lockheed, Chrysler, Ford) began to use CAD systems. In 1975 Textronic developed the first 19-inch screen, as well as the first system CAD/CAM from AMD (Marcel Dassault Aircraft), with Lockheed being the first company to acquire it. Two years later, Delta Technical Services was created at the University of Cambridge and a year later the first graphic terminal was developed using raster technology with Computervision.

The price of CAD systems in these late 70s was around US$125,000.

In 1979, Boeing, General Electric and NIST developed a neutral data exchange format IGES (Initial Graphics Exchange Standard) and in 1980 Matra Datadivision was created. In that same year, Investrónica was born, a Spanish company with CAD and CAM developments aimed at the textile-clothing sector.

Finally, in 1981 Dassault Systèmes was created, as well as the company 3D/Eye Inc. became the pioneer in 3D and graphics technology, based on developments at Cornell University. Unigraphics presents Unisolid, the first solid modeling system on a PADL-2 computer.

In the 1980s, John Walker founded AutoCAD (1982) along with 12 other founders. Composed of 70 people, they wanted to produce a CAD program for PC at a cost of less than US$1000. The first AutoCAD is presented at the November Comdex in Las Vegas.

The universal data transfer system STEP (Standard for the Exchange of Product model data) began in 1983. Two years later, MicroStation was presented, a CAD development for PC, based on Bentley System's PseudoStation, which allowed drawings to be viewed in IGES format.

Already in the 90s, McDonnell Douglas (Boeing) selected the Unigraphics system for its company. In 1992, the first AutoCAD was born on the Sun platform, and 3 years later the first version for Microsoft Windows (version 12) was released to the market. Unigraphics made the leap to Windows in 1995, getting General Motors to sign the largest CAD/CAM contract in history with them a year later.

The world leaders in the CAD/CAM market are, in this order:.

The market volume amounts to 95.8 billion USD in the United States and 24.5 billion € in Europe.

In 1997, Autodesk developed AutoCAD R14. Beyond new utilities, R14 was a rebirth of AutoCAD. The code was completely rewritten. It did everything its predecessor did, but much better, faster, almost without errors and in a simpler way. From the installation itself, the changes were noticeable in all aspects of the system, allowing quality and productivity to be greatly improved. The importance of AutoCAD 14 is that it established a standardization parameter for all programs in the industry in relation to the small to medium-sized end user.

The new century would see the appearance of new programs, such as ArchiCAD (in versions 6.5 to 14) oriented towards a design by parametric objects built in an integrated 2D/3D medium, clearly oriented towards architecture; or sketchup, which revolutionizes the concept of CAD by incorporating the idea of ​​intuitive construction through lines of objects, very close to traditional manual drawing, but with the contribution of an associated three-dimensional construction. Likewise, the appearance of better three-dimensional modelers and programs and plug-ins for the rendering task capable of being mounted on various software platforms (such as the V-ray renderer) has built a varied and interconnected market where unique proprietary solutions are increasingly less flexible and adaptable.

Recent years have seen the emergence of the BIM (Building Integrated Model) concept, a model of exchange and interoperability between general computer-aided design programs (AutoCAD, ArchiCAD, Sketchup) and specific specialty programs.

CAD software is constantly evolving, adapting more and more to new times. The use of three dimensions is increasingly frequent, and therefore this is an aspect that is improved in each version of the programs, gaining stability, speed and performance.
