The 2000s marked an emergence of open-source CAD systems such as FreeCAD.

This was adopted by the now well-known systems SolidWorks (1995), SolidEdge (1996), and Autodesk Inventor (1999). In the 1990s, solid modeling engines were enhanced with boundary representation, a more consistent way to describe virtual objects by their boundaries and interconnections. CAD software tools empower designers to explore design ideas, modify designs easily, visualize concepts through renderings, simulate how a design performs in the real world, draft documentation, share designs for feedback, and more-facilitating innovation and allowing companies to get to market faster.ĬAD software has been around since 1959, when Doug Ross, a researcher at MIT, coined the term ‘computer-aided design’ after developing a program that allowed his team to draw electronic circuit drawings on a computer, thereby realizing its potential for rapid modification and exploration.īy the early 1980s, CAD had become integrated into the workflow of the automotive, aviation, and consumer electronics manufacturers that could afford it.

Computer-aided design (CAD) is a method to digitally create 2D drawings and 3D models that has replaced manual drafting across a wide range of industries.
