Lighting design using computer–aided design systems is an urgent and in-demand necessity that is being actively improved. The possibilities of importing and exporting 3D- models of objects into circuit modeling programs are considered, and the supported formats of 3D models of objects in three-dimensional modeling programs are compared. The main formats of photometric data files used in each of the programs for working with lighting projects are listed, examples of correct and incorrect import of three-dimensional models of objects for further work on creating lighting projects are given. The ways of solving the problems of importing and exporting object models, taking into account the textures scaled on the model itself, are proposed. The programs are considered with the allocation of opportunities and features of work in each of them. Various additions to the programs aimed at working with textures for three-dimensional objects are presented.
