Мета вивчення дисципліни: The purpose of the discipline is to acquaint the specialist with modern computer technologies of equipment design — automated design systems. The use of computers in this type of activity affects design and production technology. Electronic informatics, which in turn significantly increases the degree of integration, will undoubtedly lead to the expansion of the field of activity of designers and technologists. Mastering the latest design technologies will improve the quality of the project, speed up the creation of a production product, and reduce the time it takes to develop a potential order.

Summary of the subject: The content of the educational discipline "Fundamentals of Computer Design Technologies" consists of an introduction and four chapters and is read for 30 hours. The volume of the laboratory workshop is 30 hours. The discipline introduces the structure of modern automated design systems in mechanical engineering, examines in detail the capabilities and principle of operation of the production-neutral AutoCAD automated design system, touches on the concept of computer graphics as the main element of modern design technologies, and methods of displaying graphic information. The possibilities of automating the process of geometric modeling in AutoCAD and establishing the connection of this system with other CAD systems are also considered.
