 * The first graphic system was in mid 1950 the US Air Force's SAGE (// Semi Automatic Ground Environment // ) air defense system."
 * " In 1959 the CalComp Company is founded.
 * "The first Computer-Aided Design programs used simple algorithms to display patterns of lines at first in two dimensions, and then in 3-D."
 * "In 1962, SLS Environectics in Chicago began development of the Man-Mac machine, intended to draft plans for interior office space."
 * "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."
 * "In 1969 were founding Computer vision and Appliconcompanies. Computer vision was created to produce systems for production drafting and in the same year it sold the first commercial CAD system to Xerox."
 * " In mid 1960 large computers characterized the period, vector display terminals and software development done in assembly language."
 * "Bill Barnes established in his garage in Denver on 15 January 1962, Auto-trol and manufactured 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."
 * "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, and seconded by the Ford Motor Co."
 * "In 1960 McDonnell Douglas Automation Company (McAuto) founded, it played a major role in the CAD machine production."
 * "Today we take for granted 3D modelling, in 1968 only crude 2D drawing systems were available using terminals linked to large main frame computers."
 * "The only significant attempt to create a commercially CAD system was Control Data Corporation's Digigraphics division, a successor to the previously mentioned ITEK."
 * "Mid 1960 large computers characterized the period, vector display terminals and software development done in assembly"
 * "1967 Dr. Jason R Lemon founds SDRC in Cincinnati."
