Abstract
The objective of this study is to develop the methodology for determining the laboriousness of assignments by graphic disciplines. The results determined the volume of students’ independent work performed on discipline "Descriptive Geometry and Engineering Graphics"; 2) determined the time expenses on 1 format A4 and indicated usage of this index to design the volume of students’ independent work; 3) determined how much time reduced for expenditures to show the drawings using a computer; 4) show a comparison of 2D and 3D systems by the index of time expenses. Conclusion: The obtained data gives the ability to determine the student's independently work laboriousness.
