Embossed shape called draw bead is often designed to reinforce and stiffen thin plate structures. In this paper, we studied a method to create the draw beads by using the basis vector method, which is one of the parametric optimization methods. The shape basis vectors are created using the small latticed domains so as to express the local out-of-plane shape variation, which is based on the concept of the shape function of the finite element method. The morphing technique is employed to vary the domain consisting of the several finite elements. This method has generality and convenience in practical use, and has the important property that each vector is orthogonal. Moreover, the shape basis vector which is created from the non-parametric shape optimization method, which we have been developing is added to the shape basis vectors using small latticed domains. The effects of both types of vectors are presented through basic plate examples.
