Many Small and Medium Enterprises (SME) work as subcontractors (or co-contractors) for several clients for the design of mechanical components. During the design process, they must use a variety of Computer Aided Design (CAD) softwares and connect all the Product Data Management (PDM) systems of their customers. After defining the specific needs of these companies, we show that the available commercial CAD/PDM integrations, as well as the current literature, are inappropriate for a multiCAD/multiPDM collaborative design. Are first defined the few simple processes required to ensure an efficient collaboration. Then, the instantiation of these processes in our CAD/PDM integration can be split into four points: the general definition of a CAD product structure tree and its associated model, the conversion algorithm of the product structure to an Engineering Bill Of Material (EBOM), the creation of an Unified Modeling Language (UML) data model, an implementation based upon Component Object Model (COM) and Service Oriented Architectures (SOA) technologies. We conclude by presenting the results obtained from the demonstrator developed.

“…When the simulation results are not satisfactory, the CAD models are modified, the meshes are updated and the simulations rerun. Despite a general tendency to set up new product modelling framework for lifecycle management, the interoperability between software is still mainly ensured by numerous data exchanges based on neutral formats [1]. However, due to data loss of different nature [2], the yield of these exchanges is often low, especially when considering exchanges of complex nonmanifold CAD models.…”

Abstract Data exchanges between different software are currently used in industry to speed up the preparation of digital prototypes for finite element analysis (FEA). Unfortunately, due to data loss, the yield of the transfer of manifold models rarely reaches 1. In the case of nonmanifold models, the transfer results are even less satisfactory. This is particularly true for partitioned 3D models: during the data transfer based on the well-known exchange formats, all 3D partitions are generally lost. Partitions are mainly used for preparing mesh models required for advanced FEA: mapped meshing, material separation, definition of specific boundary conditions, etc. This paper sets up a methodology to automatically recover 3D partitions from exported non-manifold CAD models to increase the yield of the data exchange. Our fully automatic approach is based on three steps. First, starting from a set of potentially disconnected faces, the CAD model is stitched. Then, the shells used to create the 3D partitions are recovered using an iterative propagation strategy which starts from the so-called manifold vertices. Finally, using the identified closed shells, the 3D partitions can be reconstructed. The proposed methodology has been validated on academic as well as industrial examples.
