Principles of Descriptive Geometry: Textbook for students of technical speciality

Descriptive geometry is a science which studies the methods of image of spatial figures on a plane and the ways of solving of the tasks of geometric character, in particular the tasks destined for defining of a mutual situation of the figures and their metric characteristics, therefore in these textbook the basic attention is spared by method of projection. The tasks destined for defining of the figures situation (this is the tasks on their belonging to each other and their mutual intersection), the tasks destined for defining of the metric characteristics (the various distances or life-size of geometric figures) are considered. Descriptive geometry prepares of future bachelors to the mastering of profile disciplines, to technical creativity (art of designing), therefore in textbook two chapters are dedicated to a curve lines and surfaces and development of surfaces. This is the 2nd additional edition
