Students experience the greatest difficulties when applying dimensions due to the fact that they do not have sufficient knowledge of the production technology of practical experience. The novelty of the technique lies in the application of some provisions of the section of geometry called «Graph Theory». Training maps have been developed that contain algorithms of actions for the stage of applying dimensions to drawings. Particular attention of students is drawn to the knowledge gained in the study of the section of descriptive geometry «Surfaces». As the experience of introducing the new methodology has shown, thanks to the algorithms that organize the sequence of actions of students when applying dimensions to drawings, it is possible not only to help students overcome difficulties in completing an educational task. In addition, since the «Graph Theory» has some elements of the game, it is possible to captivate students with the task.
