Parametric Design Method Based on Grasshopper and Shoe Last Bottom Pattern Moulding Characteristics

To adapt to the user's need for flexible and custom design of shoes, a more efficient customization method is explored. Combined with the formation characteristics of the shoe last bottom map, each characteristic parameter and related algorithm are analysed. Based on the importance of the shape control, the feature parameters are graded. The parametric design plug-in Grasshopper of Rhino software is used to construct the automatic moulding program of the shoe last bottom to form a professional and feasible design method. Through the time consumption comparison between the traditional method and the parametric design method, the efficiency advantage is analysed, so as to truly improve the design and production efficiency of the customized shoe last bottom.
