Modern trends in the development of technology are based mainly on successful engineering activities. The combination of the most modern computer technologies and the traditions of using a pencil, drawing, drafts, and, of course, a living fruitful thought is a guarantee of the education of a genuine Engineer. On the one hand, educational technologies in engineering universities at the initial stage should be based, in our deep conviction, on school geometry. On the other hand, descriptive geometry and engineering graphics should contain examples for immersion in the chosen specialty. By order of the Ministry of Education and Science of the Russian Federation, engineering classes, in which lecturers of technical universities were involved, were organized 10 years ago in Moscow schools. The creation of engineering classes is caused by the need to instill in students an interest in the engineering profession. To successfully solve this problem, it is necessary to increase the level of students» knowledge in geometry and drawing. On the basis of these subjects, one should develop design skills and skills of using computer modeling tools. The result of this cooperation should be the involvement of schoolchildren to participate in competitions and olympiads. The Department of Engineering Graphics, Bauman Moscow State Technical University, has accumulated 30 years of experience in cooperation with specialized schools in order to develop students» interest in the engineering profession. The article provides an example of the introduction of a common cutting tool, i. e. a drill, which demonstrates the depth of engineering thought formed over a thousand-year history, into the educational process when studying geometry at school and descriptive geometry at a technical university. The drill as an object comprehensible to first-year students is used to provide the basic knowledge of descriptive geometry. In addition, the problem related to the improvement of the technology of end-to-end training throughout the course of obtaining an engineering education is touched upon.

The article discusses the problems of teaching students engineering and computer graphics in a single course based on a computer-aided design (CAD) system. Examples of training tasks for acquiring knowledge, skills and abilities in the environment of the drawing and graphic editor of the AutoCAD system are given. They are necessary when performing drawings on engineering graphics, as well as the graphic part of course projects for students of mechanical specialties. Examples of exercises for self-study of the material are considered for a deeper study of the drawing-graphic module structure of the system and the acquisition of skills to work with its tools. The article also discusses several topics for studying the graphical editor AutoCAD, it reveals their contents and provides methods for completing practical tasks. A comprehensive training program extends the ability of teachers to submit material, increases students' interest in graphic disciplines, so it can achieve better results in their development. However, there are a number of problems with this approach. Different levels of basic knowledge of students in the field of computer technology require greater individualization in the organization of the educational process. An additional burden for the teacher is to check the electronic drawings and to control the independence of students' work when performing graphic works using CAD. Combining engineering and computer graphics requires more intensive work from students. It is noted that the implementation of the proposed set of tasks is only the first stage  of training students in computer technologies for creating design documentation. The acquired knowledge, skills and working skills in the environment of the AutoCAD system will be in demand when studying modern means of three-dimensional modeling. The execution of drawings using computer tools is undoubtedly more attractive to students, compared to traditional drawing. It is also important to create conditions for actualizing the intellectual potential of students, as well as the formation of positive motivation. Enthusiastic students independently master the functions of the system that are not intended for study by the curriculum. They participate with pleasure in Olympiads in engineering and computer graphics. Ways of improving the verification of graphic works by a teacher are developped.  A partial solution to the problem of checking the graphic part of course projects using preliminary drawings in a draft version and intermediate printouts of their electronic versions are proposed.

In the past decade is widely discussed the problem of geometric and graphic training of students of technical universities in Russia. In 1980-2005 arose contradictions between traditional and innovative methods of teaching for descriptive geometry and engineering graphics. This marked the article Professor P.A. Tunakov, in which descriptive geometry was carried to a dying science. This radical statement in subsequent years was supported by V.A. Rukavishnikov [15; 16] and A.L. Kheifets. An additional impetus to discussions was given by the developers of the Federal state educational standards of higher education (FSES), which declared the competence approach to the process of learning and evaluation of knowledge of graduates. Introduction in educational process of computer graphics and the appearance of technologies of 3D modeling prompted some representatives of the departments of engineering graphics towards the radical statements: • descriptive geometry as a graphic discipline became "moribund", "morally obsolete"; • it is necessary to refuse from the method of projection, as "fundamentally important is a matter of conformity to the dimension of the three-dimensional computer model and the modeled object". The article proves the incorrectness of these statements. History and background of transformation of the descriptive geometry in the engineering geometry are shown: 1) references to the dynamics of change subjects of presentations at the Moscow seminars on descriptive geometry and on engineering graphics during 1944–1965; the themes of dissertations on the specialty 05.01.01 engineering geometry and computer graphics (up to 1977 – applied geometry and engineering graphics); 2) the requirements of competence-based learning model to establish: • intrasubject links (combination of synthetics and analytical methods of problem solving); • interdisciplinary connections by expanding the subject of the discipline of the multidimensional shapes; 3) the incorrectness of opposing the "by the radicals" of 2D and 3D models, for they are complementary the types of modeling single method of two images.

To implement the requirements of the main educational programs in the descriptive geometry and engineering graphics disciplines, an analysis has been made of the students 'low academic performance in recent years and modern auxiliary methods have been proposed to increase the level of students' mastering of these disciplines. As a result of the analysis of low student performance in these disciplines, external and internal causes are identified. External reasons include: the adaptation of freshmen to new learning conditions; lack of an initial base for descriptive geometry and drawing. Internal reasons include a decrease in the classroom load and a change in the form of final certification. Of these reasons, to improve the quality of teaching, it becomes necessary to adapt teachers to new working conditions, which entails a revision of teaching methods and technologies. In order to increase the level of students' mastery of the disciplines «Descriptive Geometry» and «Engineering Graphics» and to save educational time in the learning process, it is necessary to introduce interactive teaching methods. New technologies help shape spatial thinking, develop and shape the professional competencies of students. To implement interactive methods, various tools are used as software, which allow you to create supporting training materials. Based on various types of work with students, this paper proposes a classification of tools for creating educational materials or implementing interactive methods. In this case, the tools include software that allows you to create training videos, video materials, etc. The created material is animated videos with a detailed explanation of the tasks, video lectures, test tasks. In this paper, we propose a methodology for creating auxiliary training material. The purpose of these educational materials is, firstly, invaluable help to the student, which are aimed at the development of spatial thinking, the formation of basic theoretical concepts and ways of building drawings; secondly, saving time in the educational process.
