Historical Background[edit]

The history of Open Cascade company starts in the 1980s.[7]

1980: Matra Datavision, a French company, released the Euclid CAD system.

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 CAS.CADE (Computer Aided Software for Computer Aided Design and Engineering) created by Matra Datavision was released. CAS.CADE had been used by Matra Datavision as a platform to develop Euclid Quantum.

1996: Matra Datavision released Euclid Quantum, a new generation of Euclid.

1998: Matra Datavision changed its strategy and became a software service provider. That year the company signed an agreement with Dassault Systèmes that acquired some products from the Quantum product line - Euclid Styler, Euclid Machinist, Strim, etc.

Since the primary focus was made on services, Matra Datavision established a new business model around CAS.CADE.

1999: Matra Datavision published CAS.CADE in open source on the Internet as Open Cascade, while focusing on rendering services around it.

2000: On December 7 Matra Datavision announced the foundation of Open Cascade SAS, its subsidiary for support and development of the Open Cascade platform as well as for carrying out numerous custom development projects for its customers.

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.[8]

2004: Open Cascade platform was renamed to Open Cascade Technology to avoid name confusion with the company itself (Open Cascade).

2007: Open Cascade SAS became a subsidiary of Euriware, which was a subsidiary of Areva group.

2014: Euriware, the mother company of Open Cascade SAS was purchased by Capgemini.[9]
