Abstract Curved hull plates are essential to the construction of a ship. Moreover, curved hull evaluation is significant during the curved hull plate forming process. Most shipyards use 2D- and 3D-type wooden template to estimate curvature of plates by placing the template on specific positions of curved hull plates. Only the 3-D template can be utilized to evaluate plates that are relatively thick with large radius of curvature. In general, forming plans of the 3-D template, based on the given information, are drawn manually by workers, and the information is only given for plates that may require 3-D templates. These plates are predicted empirically by the designers in the detailed design phase, resulting in the presence of unpredicted plates. For unpredicted plates, workers used to request additional information for manufacturing, and during the process, there exists a complex information exchange between related departments, which is a time-consuming process. To solve the above-mentioned problems, in this paper, a 3-D template forming information calculation algorithm, based on the surface geometric information, was proposed. Moreover, the proposed algorithm was implemented as a computer program in which forming information of 3-D template can be calculated automatically.
