Abstract

The development of the ordinates of the theoretical drawing in most programs is carried out by the interpolation method for prototype vessels. If there are no prototypes or not enough, then the development of ordinates can be carried out by the method of affine transformations, for which one prototype vessel is sufficient. The paper presents a comparative analysis of the creation of the ordinates of the theoretical drawing in the programs «Tkorpus» and «FreeShip». The process of developing the ordinates of a theoretical drawing of a tugboat is shown in the program «Tkorpus», using the interpolation method of constructing ordinates and in the program «FreeShip», using the method of affine transformations. A comparative analysis of the obtained ordinates of theoretical drawings is carried out. The programs can be used together: «Tcorpus» to obtain the ordinates of the theoretical drawing, «FreeShip» to edit the surface of the theoretical drawing. Both programs allow you to quickly obtain the ordinates of the theoretical drawing, which reduces the time at the initial stage of the design of the vessel.
