In today's product manufacturing industry, for maintaining a high-quality design, it becomes important to not only reuse past design results, but also share and utilize information about design intention. Research within the CAD industry supports the value of retaining the design information and intention. We focused on retaining the temporary expressions of design intention, and developed a system that is able to exchange and share such information easily. This is a report about the application of this system to an actual product design and manufacturing processes.
