Why CAD has been introduced?

When was CAD invented and for what purpose?

1964: In the early 1960s the first commercially available Computer Aided Design (CAD) systems were coming out on the market. The first of these were used by large aerospace, engineering, and information technology companies like Lockheed, General Motors, and IBM.

What is the purpose of the CAD?

The purpose of CAD is to optimize and streamline the designer’s workflow, increase productivity, improve the quality and level of detail in the design, improve documentation communications and often contribute toward a manufacturing design database.

Why is Autocad so important?

It allows you to draw and edit digital 2D and 3D designs more quickly and easily than you could by hand. The files can also be easily saved and stored in the cloud, so they be accessed anywhere at anytime.

How has CAD changed history?

One of the biggest advancements that CAD has brought engineers is the ability to render parts or assemblies to their near-final appearance. This helps bring the engineering design process into reality and even pushes it a little bit into the future.
