Learning outcomes of the course unit: |
The use of computer equipment in the design of products and the accompanying technological processes led to improving the quality of production, shortening the terms from idea to product realization, flexibility in market changes and consumer requirements. The idea of supporting the automation of design in mechanical engineering with the help of a computer was born immediately after its invention. By the mid-1970s, many theories of computer-aided design had been developed. Partial successes have been achieved in a number of countries, CAD design programmes have been established. The roots of CAD are intertwined with the advent and development of computer graphics and computer aiding for sketching and drawing - CAD. When studying the discipline, students gain knowledge about the development design environment CAD, with the development of two-dimensional and three-dimensional models of details and the realization of the drawings of the constructed details of agricultural machinery. The study of the discipline is based on certain modules of the product CATIA V5 and "3D EXPERIENCE". |

Planned learning activities and teaching methods: |
The lecture material advocates the purpose, approaches and ways of working with the digital design environment, as well as with the basic commands for creating assembled units of mechanisms and machines. The laboratory exercises are conducted in subgroups in a specialized computer laboratory at the Department of Mechanization of Agriculture. Three-dimensional models of the structures are created and simulated At each exercise, students work independently on the tasks set. Students report on the performance of the tasks of the exercise leader, and after his positive evaluation, proceed to the next model. Certification of the semester is given to a student with completed tasks set by the head of the exercises. All lectures are developed on Power Point and allow remote output via the MS Teams platform. The exercises are conducted in person. |

Assessment methods and criteria: |
The formation of the final assessment is carried out on the basis of the assessments of the conduct of practical knowledge, of the intermediate tests of knowledge and of the conduct of the written examination. Additional questions are asked at the exam to shape the final assessment. The semester score is determined by the formula: SA=0,2.OP +0,2.OM+0,6.OI where SA - semester assessment; OP – assessment from practical knowledge; OM – assessment from intermediate knowledge verification; OI – assessment from the written exam. |
