The term Computer Aided Design (CAD) means the use of computer software to facilitate the generation, modification and optimization of a part or a compilation of parts. Using software to facilitate part design allows for greater accuracy, simpler and more accurate design iterations, and comprehensive documentation for part and/or project management (eg, integration with a traditional bill of materials).
The use of computers to facilitate or aid design has been around since the mid-20th century. The term “Computer Aided Design” (CAD) emerged in the 1950s and is commonly credited to Douglas Ross, a computer scientist working at MIT when the acronym was coined.
1943: The first general-purpose computer was developed in 1943 through the combined effort of US Army personnel and the Moore School of Electrical Engineering at the University of Pennsylvania. It was named the ENIAC (Electronic Numerical Integrator And Computer) and was primarily used to calculate ballistics for US Army artillery fire.
1953: The first graphs formed from mathematical equations came about ten years later and involved the use of a computer numerical control machine and a cutting tool (instead of the electronic displays you think of today). These early CNC machines translated time and position inputs (x, y and z coordinates) to make cuts in the form of common shapes (the first “graphs”).
1964: In the early 1960s, the first commercially available computer-aided design (CAD) systems were released onto the market. The first of these was used by large aerospace, engineering and information technology companies such as Lockheed, General Motors and IBM.
One of the first computer graphics display systems, the “DAC-1” (which stands for Design Augmented by Computer) appeared in 1963 as part of a joint project between two of the aforementioned companies (GM and IBM). GM unveiled the technology in 1964 and used it for nearly a decade until it was eventually replaced by a superior iteration.
1963: CAD took a huge step forward with the introduction of SKETCHPAD in 1963 by Ivan Sutherland, then working at MIT. Also known as the “Robot Draftsman”, Sketchpad was a new step forward in the field of human-computer interaction and was a major advance in computer graphics in general. Major advances include the introduction of a GUI GUI GUI graphical user interface allows users to interact with a computer device through visual aids (icons). This is in contrast to the more traditional method of computer interaction using text and object-oriented programming.
1971: Another big step forward involved the introduction of Automated Drafting And Machining (ADAM). ADAM was a CAD system designed by Dr. Patrick J. Hanratty whose company, Manufacturing and Consulting Services (MCS), provided the software to large companies such as McDonnell Douglas and Computervision.
Mid-1970s - mid-1980s: 3D CAD was first introduced in the 1970s, but not in a widely distributed fashion. CAD was still an expensive tool and the industry in general could not invest in this modern technology.
3D CAD has primarily been the preserve of the automotive/aerospace industries where the end product has high value. The general industry still used the good old A0 clipboard with pencil, eraser and paper.
1980s - Mid 1990s: As technology advanced at an ever-increasing pace and IT hardware/software became more commercially available, Nova was one of the first mechanical design firms to invest in this tool for modern design called CAD - Computer Aided Design software. To put things in perspective, Nova's first CAD workstations ran on Windows 3.1.1.
Late 1990s to Today: General industry moved slowly but steadily into the world of 3D CAD, first using AutoCAD 3D for wireframe and solid modeling, then using software such as early versions of Inventor, SolidWorks, and Solid Edge.

Maravilhosa evolução. Inclusive até nos computadores. Antes eram salas enormes. Parabéns pelo vídeo 👏.

[@nicolinodavidfilareto1109]

Sou dessa época, e fiz muitos desenhos, de elétricas, estruturas, ferragens, arquitetura, detalhes de construções, fora o conhecimento técnico, sou projetista, e conheço muitos CaDistas, não conhece nada, sou calculista também, quando saiu o cad, muitos amigos ficaram desempregados.

Hoje em dia CAD está em alta, e muitos já não usam folhas para imprimir projetos porque se faz tudo digitalmente, é bom porque também faz parte da indústria 4.0.

A impressão que passa é que seu vídeo acaba antes sem falar tudo que poderia ser falado sobre o assunto. É como um corte seco Vi outros vídeos seus e todos são assim
