cadflow GmbH
Computer-Aided Design & PLM Engineers
The company cadflow GmbH, formerly Oberdellman CAD Consulting, was founded in 1996 and has continuously evolved since then. What began as 2D CAD training to replace the traditional drafting board has developed into an expert in CAD and PLM solutions. Initially, the focus was on the introduction of 2D CAD systems, followed by the implementation of 3D systems. Over the years, cadflow GmbH has supported numerous companies in integrating CAD systems into PLM environments and in globally connecting their locations. Today, we assist our clients in adopting modern engineering technologies, including AI-supported engineering, to further enhance the efficiency and flexibility of their workflows.
