Preparation of CAD infrastructure for ITER procurement packages allocated to Korea

► It is necessary to use the same CAD platform between project partners for efficient design collaboration. ► Several unexpected problems were found during preparation of the CAD infrastructure. ► The problems have resulted in a waste of time and cost. ► The approach using the same configurations is effective to avoid IT-related problems. ► The design activities are steadily being performed on the prepared ITER CAD platform. It is necessary to use the same CAD platform for standardization and efficient design collaboration between project partners. ITER has selected CATIA with ENOVIA as the primary CAD and integration tool. During the preparation of the CAD infrastructure, there were several difficulties with respect to information technology (IT). ITER design is classified as mechanical and plant. The procurement arrangement is divided into three types; functional specification, detailed design, and build to print. Therefore, it is important to prepare the suitable prerequisites according to the design type, and to comply with CAD methodologies to avoid trial and error. This paper presents how to overcome the difficulties and how to perform the CAD activities for ITER Korea procurement packages including important matters on a CAD infrastructure in a big project.
