A useful design tool dealing with 3-D topology optimization is being developed. We aim to develop such a tool as gives engineers inspiration of concept design in the engineering field. This design tool uses an adaptive optimization with multi-level voxel mesh to get both better efficiency of calculation and better optimal topology. This paper shows that one of the new targets of topology optimization; not only to use topology optimization in the phase of concept design in engineering but also to help engineers to design more directly, the efficiency of multi-level voxel method, the performance of the adaptive optimization and some 3-D numerical examples.
