Feature Line which exists outside of the car looks like a line as the result of the remarkably small radius compared with surroundings. Feature line usually express the aesthetical characteristics like makes the body of car look smooth and massing. Also, Feature line’s position and visual thickness are very important quality elements for outside parts of the car. But they usually pass about the Feature line without definite evaluation in existing verification process. So, there should be the research about visual analysis to know the exact allowable error range of Feature line in the evaluation process. For that, it is necessary to make some samples. However making samples of Feature Line is so difficult in some reasons. First of all, samples and car body’s surface illumination should be same. Second, the shape of Feature line is so tiny. Last, Feature Line’s surface part is made of free curves. In this research, we make samples with RP, Wire-EDM, and CNC Milling, compare whether the samples’ each elements are correctly expressed or not, and finally we found that CNC Milling is the best method to express the Feature Line.
