This article examines the methodological and practical aspects of the process of creating geometric models of technical objects in automated graphics systems. The methods of geometric modeling, which underlies the design of objects, its capabilities and applications in various industries, are analyzed. It is shown that geometric modeling is an important element in the design process, which ensures the creation of accurate and detailed digital models of objects. In this regard, computer-aided design programs, such as AutoCAD and SolidWorks, are the main tool for creating new and modifying existing objects, they provide engineers, architects and designers with the opportunity to develop and modify 2D and 3D models. The paper describes the principles of parametric modeling, which are the basis for the formation of geometric three-dimensional models in automated systems, considers the features of constructing two-dimensional drawings, and draws attention to the automated method of obtaining drawing documentation. The advantages and disadvantages of the automated modeling systems AutoCAD and SolidWorks are analyzed. As examples of the use of graphic systems for modeling technical objects, two-dimensional drawings and three-dimensional models of real objects used in the shipbuilding and mechanical engineering industries and in construction, made by the author in AutoCAD and SolidWorks systems, are given. The possibility of automatically forming a two-dimensional drawing from a three-dimensional model of a part and from a prefabricated structure is proven. It is concluded that the use of automated technologies for modeling geometric models of technical objects allows creating complex and detailed models that can be analyzed, tested and optimized before moving to physical production. In modern conditions, such an approach is an integral part of all engineering and design processes.
