When I started studying engineering, CAD was usually understood to stand for computer-aided drafting. Shortly thereafter, as 3D modelers became more popular, the term colloquially came to be computer-aided design. Now, in 2020, I’m convinced we’ve arrived in the age of true computer-aided engineering, or CAE.
We’re seeing the integration of seven technologies that elevate 3D modeling tools. Transforming them from a convenience, to a sort of design assistant that participates in our product development process.
