We developed the parametric mesh morphing technique, which can be used to change the shape of existing analytical mesh models, and generate a mesh model for a new shape by morphing the mesh model for the previous one. Therefore, our method is suitable to use for analysis during the early stage of design because it reduces the amount of time required to generate analytical mesh models. Compared with conventional methods, our method preserves the geometric features of the original mesh in the morphed mesh because of geometric feature identification and parametric mesh morphing. Geometric feature identification technique can classify outside surface of mesh as plane, quadric (cylinder, cone and sphere) and free-surface. Shape of mesh can be transformed in maintaining the identified geometry feature by using developed parametric mesh morphing technique. We demonstrated the effectiveness of our method by applying it to models of a bracket and a connection rod.
