—Rapid advances in digital technologies in the last twenty years have offered cultural heritage new possibilities in conservation and promotion. 3D digiti-zation has especially become more and more affordable and efficient. This leads to massive digitization projects and increasing amount of cultural heritage digital data. As an engineering team working on industrial techniques for reverse engineering, we are deeply affected by this effect. In this paper we propose a way to combine semantic information on top of the acquisition and mod-eling steps in order to manage heterogeneous historical data. We illustrate our approach with 3 related use cases at different levels of detail. Keywords—Industrial heritage, knowledge management , 3D modeling, information visualization, levels of detail.
