This article demonstrates the possibility of a graphical program Kompas ASCON in the sphere of three-dimensional modeling of engineering and building objects. The created three-dimensional model of the training class for employees of JSC "Russian Railways" to study safety rules can have a real embodiment – all components are built according to catalogs and statements. In the course of work on this project various tools of the program are mastered: models of the room of a class of furniture are created. The basic operations of three-dimensional modeling and methods of creating assembly units are studied. All components of the class are paired. The resulting project has a high visibility and can be used as a presentation as a company that performs class projects, and the customer.

The relevance of the new forms of ecologically safe, stable in composition, in functional activity, biodegradable preparations development with a complex positive effect on plants remains high and the presented work is devoted to acquaintance with the generalized results of interdisciplinary studies for the effect on the system of soil (soil substitute) - cultivated plants by nanocompositions created based on carbon (water-soluble polyhydroxylated, carboxylated and amino acid derivatives of fullerene C60) nanostructures with additions of microelements in certain concentration ratios. Based on the previously identified concentration ranges of the tested fullerene derivatives with a positive effect on plants when treating their seeds, introducing them into the soil, other root habitats and foliar exposure, their compositions with salts of microelements were developed and in a series of vegetation and field experiments under controlled favorable conditions and when modeling oxidative stress caused by UV-B irradiation, deficiency of soil moisture, deficiency of nutrients, phytopathogens, as well as in the natural conditions of the Leningrad region, the main mechanisms of positive impact (regulatory on vital systems, adaptogenic, immunomodulatory, protective) of the created nanocompositions on plants and the prospects of their application in plant growing are shown.
