| Abstract: |
| The work aims to apply the surface reconstruction method based on 3D sketch in the personalized shoe last design. The personalized shoe last design method was studied, and the foot last design standard was determined. The reverse design method based on 3D sketch was used to create 3D sketch of shoe last containing key parameters of foot shape on foot model. According to the 3D sketch, the appropriate surface creation tool was selected to generate shoe last CAD model. By modifying the 3D sketch of shoe last, the deformation design of shoe last model was realized. Taking Geomagic Design X as the design platform and according to the foot last design standards, 3D sketch extraction and CAD model creation of shoe last based on foot scanning model are realized. By modifying the head curve of shoe last 3D sketch, a new style 3D sketch driven by sketch constraint is obtained, thus creating a new model of shoe last, and realizing the creation and redesign of personalized shoe last. |
