The purpose of this study is to support han-ok design for supply and popularization of han-ok using parametric design, To achieve this, represent design knowledge of han-ok components based on parametric rules on the basis of modeling principles and geometric association of han-ok to use various computer environment. This is realized to extract design DNA of shape and non-shape through meta modeling that be able systemically to describe information. In addition, construct the 3D Parametric model of han-ok component using this knowledge.
