Геометрические преобразования в начертательной геометрии и инженерной графике

Abstract

The publication is devoted to the analysis and justification
 of questions of teaching one of the most important sections
 of the course "Descriptive geometry" "Geometrical transformations".
 On the basis of critical analysis suggestions are made for improvement
 of a presentation technique of this section in the classroom
 and in academic literature, as well as for extension of application
 of geometrical transformations for the solution of position and
 metric tasks, surfaces modelling, and also for design of complex
 engineering forms that meets certain preassigned conditions.It is
 offered to make a number of considerable amendments to the terms
 and definitions used in the existing courses of descriptive geometry.
 Some conclusions are made, and the appropriate proposals on
 feasibility of coordination of movementtransformationteachingin
 the courses of analytical and descriptive geometry are made. It will
 provide interdisciplinary communications and allow students to be
 convinced in usefulness and expediency of a combination of analytical
 and graphic ways of geometric tasks solution. Implementation
 of these suggestions contained in the article will contribute to a real
 transformation of engineering and geometrical training and as a
 consequence, the quality of training specialists.
