The normal methods for designing and manufacturing molds (Forward Engineering) have some disadvantages that are long time and inaccuracy, especially for designing and manufacturing molds from used products. To reduce these disadvantages, one of the most modern and economically effective methods being applied is using reverse engineering (RE) in designing and manufacturing molds. In this paper, the authors apply reverse engineering in conjunction with 3D CAD software to design clay roof tile molds with short time and high accuracy. The results of the study are used for subsequent processes of manufacturing, such as CNC machining, 3D printing, or rebuilding CAD data for products with complex shapes.
