The high-level structure of modules for building special computer-aided design systems

In modern production, there is a need to design specialized products predetermined by a certain set of changing parameters. Re-designing of a product associated with adjusting some of these parameters becomes one of the tasks for an engineer to complete. Using of heavy computer-aided design systems in such cases can lead to a significant increase in labor costs. Creating a history of building a solid model of a product balanced according to a given set of its parameters has a significant impact on the overall complexity of the design process. Increasing the efficiency of this process allows the use of special computer-aided design systems aimed at creating a parameterized model of a particular product. This paper presents the structure of high-level modules that ensures the rapid development of special computer-aided design systems. One of the methods that provide rapid development is the reduction of a large amount of knowledge of the classes and methods of the geometric core being used. The presence of separate functional blocks helps to build various solid-state modeling systems: from simple linear systems to systems with advanced modeling, analysis and data import/export capabilities. To reduce the dependency of the developed systems on a specific geometric core, the high-level structure that is being proposed provides the hiding of the geometric core being used by means of the private implementation design pattern.
