The book discusses the well-known Russian KOMPAS-3D program, the main components of which are the KOMPAS-3D 3D modeling system and the COMPASS-Graph drawing editor. The COMPASS system is constantly being improved, in versions V17 and higher, compared to previous ones, there have been significant changes in the interface and terms. These changes are reflected in four chapters of the book, which also covers general information on designing based on 2D- and 3D technologies. The main advantage of the book is in the variety of developed training tasks presented in four chapters and aimed at creating skills in 2D- and 3D modeling. The features of performing tasks are disclosed in the figures, which show the sequence of operations related to the construction of certain images and models. The order of presentation and the content of tasks ensure that the techniques for creating solid models and design documentation of products are gradually and completely mastered.
