During many years cadett ELSA was developed in a close cooperation between cadett ab in Sweden and MG-Data GmbH in Germany. In Germany the product was sold under the name MG-CAD.

The cooperation between the two companies became closer and closer, and in 2003 a merge occurred when cadett acquired the German business.

Consequently in 2003 a cadett office was opened in Jülich, between Düsseldorf and Aachen.

In 2003 MG-CAD and cadett ELSA were completely integrated to form a common multilingual product supporting multiple standards under the same name - cadett ELSA - in the entire world.

cadett GmbH is a fully owned daughter company of cadett Sverige ab.
