Abstract
As a place for co-creation, one interactive WWW site is under construction so as to prepare a freedom of design. This site consists of products from such projects as "Data & Engineering", "Landscape Materials", "Virtual Engineering", "Materials Design" and "Dream Driven Artifacts", and three subjects, which are now under browsing of solution spaces and formulation as inverse problems, are introduced as milestones for establishing key technologies for Da Vinci Factory, namely, multi-scale modeling, multi-operational manufacturing and multi-criteria solution. These preparations are to be abstracted into a new engineering field, i.e., co-creation engineering.
