The system costs half million dollars and were sold in few units. The only significant attempt to create a commercially CAD system was Control Data Corporation's Digigraphics division, a successor to the previously mentioned ITEK. In mid 1960 large computers characterized the period, vector display terminals and software development done in assembly language. In 1962, SLS Environectics in Chicago began development of the Man-Mac machine, intended to draft plans for interior office space. Charles Eastman at Carnegie-Mellon University, the Building Description System is a library of several hundred thousands architectural elements, which can be assembled and drawn on screen into a complete design concept. Early work in this direction had been produced by Prof. The first Computer-Aided Design programs used simple algorithms to display patterns of lines at first in two dimensions, and then in 3-D. It will play a major role on CAD developments with the introduction of CADD program. In 1960 McDonnell Douglas Automation Company (McAuto) founded. Hanratty was a co- designer of DAC ( Design Automated by Computer ), the first production interactive graphics manufacturing system. While at General Motors Research Laboratories in the 1960s, Dr. Inputs commands were done with an electronic light pen. The ITEK project was called The Electronic Drafting Machine and used PDP-1 computer from Digital Equipment Corp., a vector -refresh display and a large disk memory device used to refresh the graphic display. Parallel projects were developed at ITEK and General Motors. 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. Bill Barnes established in his garage in Denver on 15 January 1962, Auto-trol and manufactureed the first product, a digitizer. 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. 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. The system involved the use of CTR displays to show computer-processed radar data and other information. The system was developed at Massachusetts Institute of Technology's Lincoln Laboratory. ![]() History of CAD The first graphic system was in mid 1950 the US Air Force's SAGE ( Semi Automatic Ground Environment ) air defense system.
