The connection of resources, data, and knowledge through communication technology plays a vital role in current collaborative design methodologies and Product Lifecycle Management （PLM） systems, as these elements act as channels for information and meaning. Despite significant advances in the area of PLM, most communication tools are used as separate services that are disconnected from existing development environments. Consequently, during a communication session, the specific elements being discussed are usually not linked to the context of the discussion, which may result in important information getting lost or becoming difficult to access. In this paper, we present a method to add synchronous communication functionality to a PLM system based on annotated information embedded in the CAD model. This approach provides users a communication channel that is built directly into the CAD interface and is valuable when individuals need to be contacted regarding the annotated aspects of a CAD model. We present the architecture of a new system and its integration with existing PLM systems, and describe the implementation details of an annotation-based video conferencing module for a commercial CAD application.

During the last two decades,industrial applica-tions of augmented reality(AR)have been incorporated in sectors such as automotive or aeronautics in tasks including manufacturing,maintenance,and ***,AR’s potential has yet to be demonstrated in the railway sector due to its complexity and difficulties in automating *** work aims to present an AR system based on HoloLens 2 to assist the assembly process of insulation panels in the railway sector significantly decreasing the time required to perform the *** with the technical description of the system,an exhaustive validation process is provided where the assembly using the developed system is compared to the traditional assembly method as used by a company that has facilitated a case *** results obtained show that the system presented outperforms the traditional solu-tion by 78%in the time spent in the localization subtask,which means a 47%decrease in the global assembly ***,it decreases the number of errors in 88%of the cases,obtaining a more precise and almost error-free assembly ***,it is also proven that using AR removes the dependence on users’prior knowledge of the system to facilitate assembly.
