Course abstract

The aim of the study course is to create and develop geometrical logic, spatial thinking and imagination. The basic method used in course framework is the graphical method. The students get thought to draft and read drawings what is the international graphical method and means of expression of constructive thought.

Learning outcomes and their assessment

1) Knowledge - understands the projection method, view, and section view creation principles. Familiar with the drawings related standards (ISO, LVS, GOST, etc.). Knows the type of items and the relevant working documents and the execution sequence. Knows how to explain the drawing and add dimensions and annotations of threads, surface finish and material. Knowledge is appreciated in tests and laboratory works.
2) Skills – knows to create part working drawings, axonometric views, perform drawings of dismountable and rigid assemblies and text documentation for it, as well as read assembly drawings and detailing them according LVS, EN, ISO, GOST, etc. standards. AutoCad Mechanical software is used to perform these tasks. Skills are appreciated in tests and laboratory works.

3) Competence – ability to apply professional knowledge and skills of Engineering graphics in practical work and studies. Competence is appreciated in tests and laboratory works.

Requirements for awarding credit points

Students receive a final mark if they have successfully completed the tasks assigned in laboratory works and have passed 2 tests.
The tasks performed in the laboratory works have to be presented. Presentation includes short oral report of each finished task as well as answers to the questions about the theoretical aspects of this topic.
In the first test drawing of parts is required, but the second one a detailing of assembly drawing is done.
Theoretical knowledge is assessed as a test.

Description of the organization and tasks of students’ independent work

Part drawing with offset and revolved sectional views.
Construction line of intersection of surface in part drawing.
Drawing of threaded parts.

Criteria for Evaluating Learning Outcomes

A student will get a successful mark on the test work if at least 50% of the tasks are properly solved. The student receives high marks if the tasks performed in the laboratory and independent works are completed, well-designed and the student is able to answer the questions.
