The purpose of this paper is to propose a new scheme using the finite-element method for modification of a three-dimensional shape. When designing a curved surface, we need to have the following processes. First, various regions on a curved surface are transformed into flattened forms. Second, a curved surface is recovered from the flattened forms. Third, a new surface has to be made on the basis of the modified flattened shapes. We have already proposed methods for developing any curved surfaces and for recovering curved shapes with the use of the finite-element method. We now introduce a new idea for modification of 3D-curved surfaces using reformed flattened shape lines and additional information. To illustrate the usefulness of the method, We apply it to a shoe model as a typical and practical application.
