Control works problems in descriptive geometry

Abstract

There are two collections of worked problems in descriptive geometry corresponding to two control works. The both collections contain some variants and are offered for individual work of students. Each of the variants consists of two conditions a and b. The size of the drawing page required for solution of these problems is 420x297mm (or two pages of 210x297 mm). The first control work ensures four primary chapters of the course: projections of points, of straight lines, of planes and their mutual combinations of location in space (perpendicular, parallel, intersection or non-intersection). The problems should be solved by drawing the given geometrical elements specified by the coordinates of the points involved. The first control work is suggested for students after studying the four mentioned chapters of the theory. The second control work is devoted to the problems of intersection of geometrical forms with a plane and with a straight line. The conditions of the problems are presented in graphical form. Students must copy the geometrical elements from the conditions of problems with scale factor equal to 2. These problems should be solved by methods of transforming the drawing by rotation and introduction of additional planes of projections. Hidden lines must be shown by dashes. The second control work is prefered for students after finishing of the exercise 9 and corresponding individual graphical home works.
