In this paper, we propose a tool creating support system using evolutionary techniques. Here, a tool is defined as an object which consists of multiple parts, and is encoded to tree structure. The proposed system is composed of two phases: the fundamental-parts-generation-phase where each fundamental part is generated, and the structuring-phase where the generated parts are combined. On each phase, evolutionary techniques which utilize user's evaluations as decision of fitness are employed. Therefore it is possible to obtain desirable shapes for users. We have implemented the system on the O2 workstation, and have evaluated the proposed system. It is confirmed that various novel shapes can be obtained.
