In today's globalized markets, effectivity in the way that product development information is communicated and transparently interpreted by a diversity of divisions and disciplines in an enterprise has an essential impact on the key factors time, cost and quality. Against the background of current activities in the automotive industry, we have conducted a process chain analysis at multiple OEMs and suppliers, analyzing application potentials of JT as the format of origin specifically for CAx processes, such as Digital Mock-Up, Simulation and Downstream production. In this context, a simple application to investigate and manipulate JT data in terms of structure and properties would provide the means for prototypical integration tests. Connecting containers available in the JT Open Toolkit to those provided in the OpenSceneGraph (OSG) graphics toolkit, the fundamentals of such an application were developed and are presented in this paper.
