Computer Graphics. Overview of CAD Technologies

Abstract

The purpose of the article is to review computer-aided design systems (CAD systems), types of CAD systems and their features.
 The research methodology consists in reviewing and conducting an analysis of modern technologies designed to automate design work in various industries, analyzing the advantages and disadvantages of existing design systems.
 The novelty of the study. The types of CAD systems, namely CAE/CAD/CAM systems, which are used in various sectors of the national economy; classification and examples of systems by application, namely architectural and construction (AEC CAD), mechanical (MCAD), electronic (ECAD), technological (CAPP) are considered. The article also presents product data management systems, engineering calculation support and analysis systems and examples of such systems.
 Conclusions. The material presented in the article makes it possible to form an idea of the full life cycle of manufacturing a product in various fields of industrial and agricultural activity from the preliminary design, which is designed by the system, to the final stage of design – process control, preservation of complete information about the product from geometric characteristics to the analysis and calculation of engineering characteristics, which include, for example, solid mechanics and solving various problems in the field of physics, namely fluid dynamics, voltage, electromagnetics Without these systems today it is impossible to imagine high-quality production of structures, devices in any field of industrial and agricultural activity.
