This paper’s material is destined for high educational institutions’ graduate students and teachers whose professional activity is connected with problems of descriptive geometry and engineering graphics teaching improving on the basis of modern computer technology. The paper will be useful to students of technical universities in their further understanding the course of descriptive geometry and inoculation them an interest in their personal geometric and graphic training, without which a quality engineering creativity is impossible. The paper focuses on use of KOMPAS-3D software possibilities which enables solution of nearly all educational, as well as professional engineering and graphics problems. At the same time, the promotion of domestic IT-product in educational area is an urgent task, arising from the problem of technical education at the present stage of public education’s system development. A number of examples related to solution of spatial problems connected with second-order surfaces simulation have been considered. On the basis of descriptive geometry’s laws applicable to surface problems, a feature of their solution and display on computer screen has been illustrated. For example, in the graphic editor KOMPAS-3D there is the Ellipse command, but there are no Hyperbola or Parabola commands. But without these curves it is impossible to create a 3D model of hyperboloid (one- or two-sheet), paraboloid, or hyperbolic paraboloid. To create these curves it has been proposed to use conics of circular cone, canonical or parametric equations of hyperbolas and parabolas. For each of these options the examples of second-order surfaces 3D models creation have been considered.

The graduate of higher technical education institution must today possess the knowledge of information technologies from computer design systems to development of graphical models related to processes and phenomena. The interest in the engineering computer graphics must be instilled in the secondary school. Concrete results have been achieved in the Penza State Technological Academy on ECG Chair. The directions of work with students and schoolchildren in this area have been considered in the paper.
