PLM tools mainly refer information systems based on a wide graph representing linked information. Such a PLM model is compatible with a meta-model often expressed in UML. UML graphics diagrams are paradigms to support sharing and understanding the concepts and relationships that must be supported by the PLM tool. Nevertheless instance diagrams contain so many objects that it is hard to present them in a holistic view that can be easily shared by collaborators. This paper presents a 3D approach to visualize an Object-Process Methodology (OPM) model, which provides a single holistic view of a complex system and supports sharing among collaborating parties. This approach has been applied to managing the complex information related to VISIONAIR – a European visualization infrastructure project, successfully enabling the management of 123 simultaneous projects.
