Abstract:
1. A computer-implemented method for updating a CAD/CAM modeled object to be updated in a Product Lifecycle Management (PLM) system, the method comprising: (a) accessing a directed acyclic graph modeling a CAD/CAM modeled object to be updated, the CAD/CAM modeled object to be updated being a modeled object in a CAD/CAM model in the PLM system, and the directed acyclic graph comprising at least one path comprising nodes and arcs, wherein: (b) building a first path of all successive nodes used by the CAD/CAM modeled object to be updated, the first path comprising a root node; (c) computing, from the first path, a second path of nodes impacting the update of the CAD/CAM modeled object to be updated, said second path excluding (i) nodes of the first path that are irrelevant to the update of the CAD/CAM modeled object, and (ii) arcs of synchronized status, such that said second path has reduced data relative to the first path; and (d) updating the CAD/CAM modeled object to be updated and the CAD/CAM model by using the nodes of the second path exclusive of the nodes of the first path that are irrelevant to the update of the CAD/CAM modeled object, said nodes of the second path being nodes of arcs of unsynchronized status.
