What was CAD first used for?

CAD meets CAM

His invention was designed to aid the design and tooling of cars by integrating drawing machines, computer control, interactive free-form curves, surface design and 3D milling for manufacturing clay models and masters.

When was CAD drawing invented?

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. In 1960, Ivan Sutherland MIT’s Lincoln Laboratory created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing.

When was CAD first used in architecture?

In the 1970’s, early CAD programs gave architectural and engineering technicians the ability to produce 2D designs that were equivalent to hand-drawn drafts. However, it wasn’t until the 1990s that CAD programs, such as AutoCAD, became an industry staple and were used by architectural and engineering firms everywhere.

How did engineers design before CAD?

Before the launch of AutoCAD and other design software, engineering drawings were made on sheets of paper using drawing boards. Multiple pieces of equipment were required to complete a given drawing such as drawing boards, different grade pencils, erasers, T-squares, set squares etc.

What is the history of drafting?

The earliest historical record of drafting goes back to 2000 BC, as proven by a recovered fossilized plan showing an aerial view of a Babylonian castle. This showed that, even in the early eras, people used drawings to guide them in building structures.
