This was the interest group of CAD, PDM and PLM providers from 1995 to 2023

The sendler\circle is history. The last meeting took place on September 18 in Hamburg. I have published a final report about it. There will soon be a few articles here that trace the history of the circle over almost three decades. After all, it has played a not insignificant role in the development of digitalization, especially in the manufacturing industry in Germany.

The information relating to the sendler\circle in its last period is currently still online here. And the members who last made it up.




This is where the managing directors or marketing directors of important providers of software and services for industry, especially in the field of PLM, Industry 4.0 and the Internet of Things (IoT), meet to exchange experiences and discuss general market developments. Not always in such beautiful places as the Irsee Monastery (photo Christoph A. Hellhake). But often. Top-class speakers shed light on topics that are burning on the industry’s nails, and representatives of the manufacturing industry report from practical applications.

The IT offerings of the member companies focus on the product development process in the manufacturing industry and on the management of the product data created there throughout the entire product life cycle. From CAD/CAM/CAE and PDM to collaboration of distributed teams, project and process management and virtual reality to interfaces to other application areas such as ERP, SCM and CRM.

Between meetings, the sendler\circle also forms the hub of communication among participants and is the industry’s interface with third parties.
