this paper, we propose a method of free-form surface construction for conceptual design.In general, it is difficult to construct the free-form surfaces in such design process.In order to solve this problem,we have developed a method to generate initial free-form surfaceswhich envelops simple polyhedra (called primitive) group arranged in a three-dimensional space.This generated shape by the method is used as an initial shape ofan external shape of a designing product.Therefore, it is important to be able to manipulate the generated shape easily.In our method,the shape which envelops all primitives is constructed by a curve networkthat is defined by the center of gravity and assigned radiuses of curvature tovertices of the primitive.The initial curved surface shape is generated by interpolating this curve network.As the greater part of this process manages only curves,we can realize a high-speed execution and an easy modification of the result shape
