Course abstract | |
The aim of the course is to create and develop geometrical logic, spatial thinking and imagination, to get acquainted with the terminology of engineering graphics, to obtain extended understanding on the concept of computer aided design and spheres of usage in solving of engineering problems, as well as basic principles of computer aided system selection, to promote the use of standards (LVS, ISO, etc.) in creation of technical documentation. Practically students acquire the possibilities of drawing of different components using AutoCAD software package. | |
Learning outcomes and their assessment | |
Knowledge – understands the projection method, view and section view creation principles. Familiar with the drawings related standards (ISO, LVS, etc.). Knows the types of components and the corresponding work documentation and its execution sequence. Able to explain the drawing and to add dimensions and annotations of threads, surface roughness and material. Knowledge on the concept of computer aided design and spheres of different CAD system application, the basic principles of computer aided systems selection. Knowledge is assessed in Test 1, practical works and exam.
Skills – can accomplish part working drawings, axonometric views, perform drawings of dismountable and rigid assemblies and bill of materials for it, as well as read assembly drawings and detailing them according LVS, EN, ISO, etc. standards. Skills to choose an appropriate software application related to the computer aided design sphere basing on the problem nature, to use the software in creating of technical documentation. Able to work with standardized product library elements. Skills are assessed in Homework 1 and 2, Test 2, practical works and exam. Competence, working in group or independently, to use the information technology facilities for the solving of engineering problems and to manage them, as well as to convince others and argue own viewpoint. Competences are assessed in practical works and tests. |

Requirements for awarding credit points | |
The study course concludes with a cumulative exam, with or without a final assessment during the individual study and examination period. The exam grade is based on the evaluation of study results throughout the semester (practical assignments, homework, and tests). A final exam covering the entire course material must be taken if the semester grade is 5 or lower, or if the student wishes to improve his/her semester grade. | |
Description of the organization and tasks of students’ independent work | |
Construction of joints. Drawing a detail drawing using complex sections. Construction of surface intersection lines in detail drawing. Drawing of threaded parts. | |
Criteria for Evaluating Learning Outcomes | |
All coursework during the semester (practical assignments, homework, and tests) is graded on a 10-point scale. All tasks completed in practical and homework assignments must be finished, properly formatted, and the student must be familiar with the sequence of work and be able to answer questions about it. A passing grade on the tests can be obtained if there are no significant errors in the parts or assembly drawings and at least 50% of the test questions are answered correctly. The final grade for the study course consists of: 50% from the grades of practical assignments completed during the semester, 20% from homework grades, 30% from test grades. | |
