The article highlights issues related to factors that affect the introduction of computer-aided design (CAD) systems in modern machine-building industries. The purpose of the work is to determine the main limitations and possibilities of using CAD in production and to consider the main trends in the development of system solutions for mechanical engineering problems. The theoretical basis of the work is data analysis and analytical study of the current state of proposals for CAD solutions. Electronic modeling systems allow not only to optimize the production process, reduce costs, but also are indispensable requirements for the competitiveness of modern engineering products on the world market. They allow you to carry out operational, remote interaction on the development and production of products, bringing it to the international market. Despite the variety of possibilities offered by CAD solutions from various companies and vendors, the request for its implementation by enterprises is very limited. The crisis state of the economy and industrial production is also not an incentive to implement such solutions. In this regard, it is necessary, on the one hand, to study in detail the evaluation of the effectiveness of implementing CAD technologies, and on the other hand - the most flexible software products that are adapted to the real capabilities and requirements of a particular enterprise, production process, and final product.
