Abstract: The paper presents a method for automating a portion of a drafter’s work during the parametric 3D model design phase, by using a developed application for KOMPAS-3D. Designing repetitive parts consumes a significant amount of time; therefore, the author has developed a program that enables applying parameterization mechanisms for the automatic creation of a 3D model of a prototype blank. The automation process involves using the created KOMPAS-3D application, which allows parameters that form the 3D model to be manipulated through a variable input window. The developed program aims to eliminate the user’s interaction with Boolean operations and sketches, and to create an application library for standard parts. The developed application, which automates the 3D model creation process, is implemented using the Python programming language and the KOMPAS-Macro application. The paper demonstrates the proposed method for automating the design of parametric 3D models of prototype blanks, through automated creation of the parametric 3D model, using the example of designing a “glass” part. To evaluate the effectiveness of this method, the author conducts a comparative analysis of the time spent modelling this part using the traditional method with Boolean operations, and using the developed program. The results show that the drafter’s time spent creating the 3D model of the proposed part is reduced several times over using the automated method. Modelling the process of automated design of a parametric 3D model of a prototype blank, based on the proposed algorithm, is implemented using the graph theory. This method can be useful for a programmer-engineer with experience in Python programming and skills in developing design documentation using the mechanical engineering configuration of KOMPAS-3D for creating their own embedded application library, as well as for a design engineer who solves problems to ensure the technological sovereignty of the country.
