Preliminary evaluation of the predicted efficiency of the optimization problem of the rational orientation of the product in the working space of layered construction of additive units is proposed to perform based on the analysis of the original triangulation 3D-model of a complex product by its spherical mapping. The condition of reflection on the sphere is that the values of angles in the spherical coordinate system for the faces normal of the triangulated model of product fall into the range of values of a certain triangular face of the sphere model. Examples of evaluation based on the analysis of spherical mapping of the original 3D model of products are considered. Industrial products with different surface complexity were selected as test 3D models. This approach allowed to perform a comparative analysis of the results depending on the design features of the products. The practical implementation was performed in the subsystem of visual assessment of geometric characteristics of triangulated 3D-models, which is part of the technological preparation system for the complex product manufacture by additive methods. This system was developed in NTU "KhPI" Department of Integrated Technologies of Mechanical Engineering named after M.F. Semko.
