Computer Aided Design

Course developer

Course abstract

The aim of the studying course is to get knowledge about computer aided design and possibility to use CAD software to solve engineering problems and process automatization. Students learn the rules of design and automatic creation of drawings.

Learning outcomes and their assessment

1) Knowledge – Students understand the principles of modelling and are familiar with methods of digital prototype design of parts and assemblies with several features and standard mates. They know the possibilities of automatic creation of parts and assemblies drawings. Knowledge is appreciated in tests and laboratory works.
2) Skills – Students know to design parts with several features, create automatic views and sections and perform drawings according LVS and ISO standards. Skills are appreciated in tests and laboratory works.
3) Competence – ability to apply professional knowledge and skills in practical work and studies to solve different engineering problems. Competence is appreciated in tests and laboratory works.

Requirements for awarding credit points

Passing the independent assignments during the semester and receiving a successful grade for them will result in a pass.

Description of the organization and tasks of students’ independent work

Advanced sketching. Design of threaded parts – cosmetic, simplified, and schematic tread. Modeling of casting part. Drawing. Modeling and drawing of revolution solid. Modeling of mechanism and creation assembly drawing.

Criteria for Evaluating Learning Outcomes

The results are assessed according to the number of independent tasks submitted, the number of errors (up to 4 points), and their degree of importance (up to 4 points). The student's attitude towards the study course is also assessed, consisting of timeliness, communication and diligence (up to 2 points).
