Daimler has completed a groupwide transition to Siemens NX CAD software, which replaced Dassault Systemes' Catia V5 software across all of the company's divisions.

The German car and truck maker said the move, which involved training more than 6,200 users on the new software, was made to improve efficiency and sustainability. Daimler said in a press statement that the transition, which was first announced in 2010, also resulted from a desire to achieve full integration between the group's product data management, which already used Siemens PLM Teamcenter products, and CAD software systems.

"The introduction of the new design and product data software not only means that we are well prepared for the future," Daimler CIO Michael Gorriz said in a statement. "We have also taken the opportunity to bring our engineering processes in line with the highest standards in the automotive industry."

Gorriz said relevant suppliers to Daimler already are using Siemens NX or have adopted the software to safeguard the supply chain.

The Daimler CIO, who is leaving the company later this year, called the the move "our biggest IT migration project in recent decades." The project, which relied heavily on more than 300 employees in Daimler's r&d office in Bangalore, involved migrating more than 235,000 CAD objects to the new software.

The whole project was completed on schedule, he said.
