This study is conducted to improve the efficiency of shape design of a product. An efficient method to re-construct surfaces in the phase of surface evaluation is proposed. Usually, quality evaluation of product shape is implemented by checking the pattern of highlight lines: reflection of fluorescent tubes arranged parallel to each other. However, if required highlight lines are not obtained, the model should be modified by numerous procedures. In this study, a system for constructing surfaces which show the required highlight lines entered intuitively with a mouse or pen tablet device is constructed. As results, (1) a method of defining an evolute which stands for the locus of the curvature centers in a cross section of the surface from highlight line information is proposed, (2) it is clarified that surface having the required highlight lines defined by the involute can be obtained, (3) the system is constructed by mounting the algorithm on the computer based on the proposed method, and (4) The usefulness of the proposed method is confirmed through fundamental experiments.
