 1987: Euclid-IS, the first integrated CAD/CAM system, appeared.
 1993: Euclid 3 was released. This was a completely new and unique system that supported concurrent engineering. Euclid software made Matra Datavision a true market leader in the field of CAD/CAM. Euclid was employed in the widest variety of engineering domains, from general mechanical and automotive engineering to the complex robotics and aerospace industries.
 1993: a development platform called CASCADE (Computer Aided Software for Computer Aided Design and Engineering) created by Matra Datavision was released. CASCADE had been used by Matra Datavision as a platform to develop Euclid Quantum.

 2003: Matra Datavision, the parent company, was purchased by IBM, while Open Cascade was acquired by Principia Research & Development – a French editor of finite-element solvers and provider of engineering services.
 2004: The Open Cascade platform was renamed to Open Cascade Technology to avoid name confusion with the company itself (Open Cascade).
