what is CAD and history of CAD softwares?
CAD is short form of
COMPUTER ADDED DESIGN
Its mean a design which made by the help of computer is CAD.
1950 - 1970
The beginnings of CAD can be traced to the year 1957, when Dr. Patrick J. Hanratty developed PRONTO, the first commercial numerical-control programming system.He known as -

Its mean a design which made by the help of computer is CAD.
1950 - 1970
"the father of CAD CAM"
The first graphic system was also use 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.

Later In 1960, Ivan Sutherland MIT's Lincoln Laboratory created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing.
their hard work and research give us great CAD system which make our production in every field very accurate and easy.
best advantage of CAD software is we can make more drawings in less time with more accuracy than drafting sketch board.
This is beggining of 2D CAD SYSTEM
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.

at this time In 1959 the CalComp company is founded which famous for its plotter for cad drawings .
In mid 80s Colma was acquired by General Electric and then sold to Prime Computer.
M&S Computing founded (later becomes Intergraph). At the beggining it was a consulting firm that supported government agencies in using digital technology.
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.
1970
Colma 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 Colma was acquired by General Electric and then sold to Prime Computer.
M&S Computing founded (later becomes Intergraph). At the beggining it was a consulting firm that supported government agencies in using digital technology.
1972-
MCS was founded in 1971 by Dr. Patrick J. Hanratty. Since the day it was founded in 1971,
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

1973
Initial release October 1973
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 mapp

1976
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.
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.

1993
SolidWorks Corporation was founded in December 1993 by Massachusetts Institute of Technology graduate Jon Hirschtick. Hirschtick used $1 million he had made while a member of the MIT Blackjack Team to set up the company.[4] Initially based inWaltham, Massachusetts, United States, Hirschtick recruited a team of engineers with the goal of building 3D CAD software that was easy-to-use, affordable, and available on the Windows desktop. Operating later from Concord, Massachusetts, SolidWorks released its first product SolidWorks 95, in November 1995
