List of CAx companies

This is a list of computer-aided technologies (CAx) companies and their software products. Software using computer-aided technologies (CAx) has been produced since the 1970s for a variety of computer platforms. This software may include applications for computer-aided design (CAD), computer-aided engineering (CAE), computer-aided manufacturing (CAM) and product data management (PDM).

The list is far from complete or representative as the CAD business landscape is very dynamic: almost every month new companies appear, old companies go out of business, companies split and merge. Sometimes some names disappear and reappear again.
