In this paper we present a pattern development method for soft product design. To take into account of physical properties of the material, a physically-based surface fattening method is used to create 2D patterns from a 3D model. We employ multilevel meshes to expedite the flattening process, and a boundary optimization method is proposed to guarantee 2D patterns can be sewn well. We apply the proposed method to the design of real soft products, and experimental results show that it can deal with complex surfaces efficiently and robustly, and manufactured products are satisfactory.
