Who invented cad software

Modern engineering design and drafting are largely attributed to the development of descriptive geometry in the 16 th and 17 th centuries. There are two people in particular who are largely responsible for setting the stage for what we know today as computer-aided design CAD. Hanratty, and Ivan Sutherland made groundbreaking contributions, including:. The development of the sketchpad system revolutionized design because it made creating drawings and interactively moving and changing objects on a computer screen possible.

Regardless, the first simple programs were starting to change the way the manufacturing and construction industries viewed design. Much of the research moved from 2D to 3D design creation. Later in the decade, solid modeling technology for rendering 3D designs became integrated into new CAD programs. But it was still largely 2D. The later years of the decade saw the release of several 3D modeling kernels, most notably ACIS and Parasolids, which would form the basis for other history-based parametric CAD programs.

CAD Today, CAD Tomorrow The modern CAD era has been marked by improvements in modeling, incorporation of analysis, and management of the products we create, from conception and engineering to manufacturing, sales, and maintenance what has become known as PLM, product lifecycle management.

With all of this pressure on engineers and designers, what do you see as the next big evolution in CAD?

Instead, this software enabled drafters to feed their design into a computer by drawing with a light pen on a CRT monitor. Manufacturers valued CAM for its precision and ability to optimize the manufacturing process, decrease material waste, shorten turnaround times, and provide clear visualizations.

By the s, algorithms had grown increasingly sophisticated, with engines capable of advanced parametric techniques. BIM Could Help. Select From Over , Industrial Suppliers.
