One of the main principles of Concurrent Engineering is accessing the up to date design information at any moment. 3D models are the basic design information for today's industry. To work with 3D models by different departments concurrently, every model should be managed as positioned in 3D space relative to other models. This brings the term of Digital Mock-Up (DMU), digital design of the product to be developed. In order to use DMU effectively, design data should be managed in Product Lifecycle Management (PLM) tools by the help of Product Structure. In addition to that, 3D modeling rules are also important parameters to have effective DMU. Therefore, these rules should be set and every model should be created according to these rules.
In this paper, definition and management of DMU in aerospace industry are explained. Relation between Product Structure and DMU is detailed considering different DMU management methods such as “Bottom-Up Method” , “Top-Down Method” and “Hybrid Method” . These methods are also explained in this paper. Moreover, definition of Master Geometry is done and the role of Master Geometry in DMU creation is explained by using specific design examples from industry.
