The tutorial covers working in the nanoCAD Mechanics program, created on the basis of the nanoCAD CAD platform by the Russian company Nanosoft. Based on two previous works by the author "nanoCAD PLUS 10. Adaptation to the educational process "(Ser.: CAD platform nanoCAD. M.: DMK Press, 2019. 346 p.) And "nanoCAD MECHANICS 9.0. Engineering 2D- and 3D Graphics "(Ser.: CAD platform nanoCAD. M.: DMK Press, 2019. 476 p.), the content of which has been systematized, revised and supplemented with a number of new necessary information, including issues of computer-aided design of fastening joints of parts, flange joints and shafts based on specialized tools and nanoCAD Mechanics modules. Numerous examples of phased design of educational and full-scale parts and products are given. The structure and methodology of the material in the training manual correspond to the GEF HE 3 + +. It is intended for independent work of students studying in an enlarged group of specialties and areas of training "Engineering, Technology and Technical Sciences." The textbook can be recommended for teachers and graduate students of higher educational institutions, as well as for designers and technologists of various companies interested in domestic CAD platforms.
