We all know that CAD means Computer-aided design since the mid 1980s, don’t we? There also exist other computer-aided technologies (i.e CAx acronyms), some of them being directly related to CAD and the PLM workflow. Such is the case of Computer-Aided Engineering or CAE, which is also known as finite-element analysis or FEA (due to the mathematical method usually used to solve the elasticity or thermal equations). Sometimes, as in the Onshape App store, CAE is referred to plainly as “simulation” although I prefer the term “modeling.” In any case, here are five reasons why it is a good idea to add CAE to your CAD.
