A product design goes through a Digital Mock-Up which is based on the product geometric model. This latter has an important role in the design project whose exploitation mainly depends on how it has been established [1]. Furthermore, the growing competitive context hardly encourages firms to implement new working methods like collaborative engineering. However, its implementation in combination with product geometric data generates many problems in terms of project and data management. For this purpose, this article proposes a methodological solution to the problem at hand. Moreover the problem gets complicated as the project progresses. As a result, the detailed design phase becomes critical particularly in the face of this problem. Therefore, the current article focuses on this phase of the product design process through an example.
