Distributed part parametric design system based on COM/DCOM

To implement the distributed part design based on UG (unigraphics), two application development modes of UG were compared, and a universal parametric design method on the basis of a part library was presented. Through UG external programming, and utilizing COM (component object model), a universal software component for part parametric design was written, and then with the help of DCOM (distributed component object model), the distributed design using this component was achieved. Finally, considering the 3-tier network model, a distributed part parametric design system integrating this component was developed, which implemented the parametric design in a LAN (local area network) environment.
