Applying Multi-User technology for modeling complex CAD objects

Abstract

Complex CAD modelling occurring in engineering design and construction processes relies upon the effective management of teamwork where a variety of specialists work together on the development of one compound object that leads to the following issues which have to be dealt with in order to make this process time- and cost-effective: i) difficulties in exchanging technical information (including drawings) due to modifications in the CAD model; ii) difficulties in tracking modifications performed by other project participants; iii) difficulties in working with elements connected to another element already used by other participants; iv) assessment of various object versions. To facilitate these processes and manage the flow of technical information between project partners, multi-user technology is considered. It operates with a complex CAD object in the same way as an electronic archive system in engineering document management systems and offers a level of control over the information flow within the construction process.
