Abstract: All product innovations of manufacturing industry are now designed and developed using CAD (Computer-Aided Design) software. In the present study, geometry models of foot produced from the insole shoe orthotic product (ISO-product) corresponding to the contour of reliefs malformed legs due to illness (foot deformities) are described in detail in the form 3D mesh solid. In addition, the ISO-product can be made in a wide range of digital 3D design application such as foot iQube 3D scanning, 3D CAD PowerShape 2016, reverse engineering, CAE analysis and rapid prototyping/CNC machine. This study presents the stages of Reverse Engineering Design (RID) for a pair of ISO-product generated from the feet people suffering from the foot deformed. Initially, the scan to get a foot in the form of 3D meshes is presented in the STL file. A few feet of the Indonesian people by the age of fifty to mid-seventies and weight range of 50-80 kg and having foot deformities are obtained. A curved solid modeling-based on 3D surface and solid modeling of ISO-product is fitted to the contour of the scanned foot relief. The results can be a guide how to obtain the 3D surface and the solid model of the feet people with deformities for the subsequent analysis.
