Engineering Graphics

Course developer

Course abstract

The aim of the studying 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

Knowledge - understands the projection method, view, and section view building principles. 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 - graphical works, tests.
Skills – knows to draw the sketches of parts, axonometric views, design part working drawings, perform drawings and text documentation for it, as well as read assembly drawings and detailing them according LVS, EN, ISO, GOST, etc. standards - graphical works, tests.

Competence – ability to apply professional knowledge and skills of technical drawing in practical work and studies – tests.

Part time extramural studies:

All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar

Requirements for awarding credit points

Final mark is obtained if the laboratory work drawings and tests are fulfilled and defended.

Description of the organization and tasks of students’ independent work

The tasks set in the laboratory work must be completed independently, in accordance with the conditions specified in the laboratory work. Learn unclear questions from the literature. Presentation of the graphical works takes place after its completion, during laboratory work.

Criteria for Evaluating Learning Outcomes

The assessment of the course tests depends on the cumulative assessments of the graphic works and tests.
The course tests mark is calculated as the arithmetic mean of the tests and the mean course mark, which is calculated as the arithmetic mean of the marks of graphical works that is taken from the study course.
A student receives a successful mark on graphical work if the work is presented and at least 60% of the conditions are met.

A student will get a successful mark on the tests if at least 40% of the tasks are properly solved.
