Peculiarities

Along with the use of automation systems for engineering calculations and CAE analysis, at present, as a rule, CAD (Computer-Aided Design) systems are used. Information from CAD systems goes to CAM (Computer-aided manufacturing). It should be noted that the English term "CAD" in relation to industrial systems has a narrower interpretation than the Russian term "CAD", since the concept of "CAD" includes both CAD, and CAM, and CAE. Among all information technologies, design automation occupies a special place. First of all, design automation is a synthetic discipline, as it includes various modern information technologies. So, for example, the technical support of CAD is based on the operation of computer networks and telecommunication technologies, and CAD also practices the use of personal computers and workstations. Speaking about the mathematical software of CAD, it should be noted the variety of methods used: computational mathematics, mathematical programming, statistics, discrete mathematics, artificial intelligence. CAD software systems can be compared with one of the most complex modern software systems, which are based on such operating systems as Windows, Unix, and such programming languages ​​as C ++ and Java, as well as modern CASE technologies. Almost every development engineer should have knowledge of the basics of design automation and be able to work with CAD tools. Since all design departments, offices and design bureaus are equipped with computers, the work of a designer with such a tool as an ordinary drawing board or calculations using a slide rule has become irrelevant. Consequently, enterprises operating without CAD or using it to a small extent become uncompetitive, since they spend much more time and money on design.

CAD types

  • Mathematical software CAD (MO) - this type involves the combination of mathematical methods, models and algorithms in order to perform design)
  • Linguistic software CAD (LO) - this software is an expression of the languages ​​of communication between designers and computers, data exchange languages ​​and programming languages ​​between CAD hardware;
  • CAD hardware (TO) - this includes peripheral devices, computers, communication lines, data processing and output, etc.;
  • CAD information support (IO) - consists of databases (DB), database management systems (DBMS) and other data that are used in the design;
  • CAD software (software) is, first of all, computer programs CAD;
  • Methodological support (MetO) - includes various kinds of design methods;
  • Organizational support (OS) - is represented by staffing tables, job descriptions and other documents that determine the work of the project enterprise.

CAD structure

Being one of the complex systems, CAD consists of two subsystems: design and maintenance. Design procedures are performed by design subsystems. Subsystems of geometric three-dimensional modeling of mechanical objects are a striking example of design subsystems. With the help of service subsystems, the functioning of the design subsystems is carried out, their unity, as a rule, is called the system environment or the CAD shell. Typical service subsystems are the design process management subsystems (DesPM - Design Process Management), design data management (PDM - Product Data Management). Dialogue subsystem (DP); DBMS; instrumental subsystem; monitor - providing interaction of all subsystems and managing their implementation - these are serving software subsystems. The dialog subsystem of the software enables interactive interaction between the CAD user and the control and design subsystems of the software, as well as the preparation and correction of initial data, familiarization with the results of design subsystems operating in batch mode.

The structure of CAD software is determined by the following factors:

  • aspects and level of descriptions created with the help of software, designed objects and subject area;
  • the degree of automation of specific project operations and procedures;
  • resources provided for software development;
  • architecture and composition of technical means, mode of operation.

CAD classification

CAD is classified according to the following principles: purpose, application, scale and nature of the basic subsystem. According to the intended purpose, CAD or CAD subsystems are distinguished, which provide various aspects of design. Thus, CAE /CAD /CAM systems appear as part of MCAD:

  • CAD-F or CAE (Computer Aided Engineering) systems. This refers to CAD functional design
  • CAD-K - design CAD systems for general engineering, most often they are simply called CAD systems;
  • CAD-T - technological CAD systems for general mechanical engineering - ASTPP (automated systems for technological preparation of production) or CAM systems (Computer Aided Manufacturing).

By applications, the most important and widely used are such CAD groups as:

  • Mechanical CAD or MCAD (Mechanical CAD) systems are CAD systems for use in general engineering industries.
  • ECAD (Electronic CAD) or EDA (Electronic Design Automation) systems - CAD for radio electronics.
  • CAD in the field of architecture and construction.

In addition, there are a large number of more specialized CAD systems, either allocated in certain groups, or being an independent branch in the classification. These are such systems as: BIS-CAD (large integrated circuits); CAD for aircraft and CAD for electrical machines. By scale, independent software and methodological complexes (PMC) of CAD are determined:

  • Complex for strength analysis of mechanical products in accordance with the finite element method (FEM)
  • Complex for analysis of electronic circuits;
  • PMC systems;
  • Systems with unique software (software) and technical (hardware) architectures.

Classification by the nature of the underlying subsystem

  • CAD, which are aimed at applications where the main design procedure is design, that is, the definition of spatial forms and the relative position of objects. This is a CAD based on computer graphics and mathematical modeling. This group of systems includes most of the graphic CAD cores in the field of mechanical engineering.
  • Application-oriented CAD systems in which a large amount of data is processed with fairly simple mathematical calculations. It is CAD based on DBMS. CAD data is mainly found in technical and economic applications, for example, in the process of designing business plans, objects like control panels in automation systems.
  • Complex (integrated) CAD, which include a set of previous types of subsystems. Typical examples of complex CAD systems can be CAE / CAD / CAM systems in mechanical engineering or CAD BIS. Thus, the DBMS and subsystems for designing components, schematic, logical and functional circuits, topology of crystals, tests for testing the suitability of products is an integral part of CAD LSI. In order to manage such complex systems, specialized system environments are used.
  • CAD based on a specific application package. In fact, these are freely used software and methodological complexes, such as a complex for simulating production processes, a complex for the synthesis and analysis of automatic control systems, a complex for calculating strength using the finite element method, etc. As a rule, CAD data refers to CAE systems. For example, logical design programs based on the VHDL language, mathematical packages such as MathCAD.

Development of CAD

One of the key topics in the development of CAD is "cloud" computing: remote work with data hosted on remote servers from various devices with Internet access. To date, clouds have made very significant progress in the segment of light applications and services - mainly in the consumer sector. There are two options for integration. In the first case, the entire infrastructure of engineering services is transferred to the cloud, and, accordingly, the need for engineering software installed at the workplace disappears altogether. In the second case, the designer still has a graphical workstation with CAD installed, but at the same time he gets access to various cloud services, thanks to which it is possible to solve tasks that require very significant resources (for example, to carry out a strength analysis). Cloud interaction is possible in two ways: publicly, when access to the server located at the provider is open via the Internet, and privately, when the server is located at the enterprise and it is accessed via a closed local network. In Russia, the development of clouds in the field of CAD is constrained by the need to maintain excessive secrecy in so many projects. Therefore, it is most likely that private clouds will become the main driver of the market in the near future. Clouds are not only new technologies, but also an opportunity to experiment with new business models.

The next important trend is alternative operating systems. Five years ago, when there was talk about an alternative to Microsoft Windows, it was usually about Linux. This topic is still relevant today: the domestic national software platform, most likely, will be made based on the Linux kernel; there is a growing interest in this OS in the field of education and in government agencies (there are examples of a successful transition). However, now we can already talk about the significant potential of the Google Chrome OS operating system. And here the mentioned trend merges with the cloud trend - Google OS, as you know, does not imply installing applications on a local computer.

An important role in the promotion of this OS is played by the trend towards a decrease in the market share of PCs. Obviously, if most of the cumbersome and complex calculations are transferred to the clouds, the requirements for hardware and it becomes possible to work on any device. For example, on tablets. As a result, developers of CAD solutions will either have to develop platform-independent solutions (cloud version) or make them multi-platform.

The next topic is `hardware`. Here, again, everything is determined by the market's dissatisfaction with the monopolist's decision - the classic Intel architecture (the pace of its development). In this regard, there is a clear trend towards the development of the ARM architecture. It is now supported by several manufacturers, among which one of the most active is Nvidia (Nvidia). So far, this architecture is actively used only in mobile devices, but in the near future, apparently, it will also be transferred to stationary PCs. Indirectly, this is evidenced by the fact that the future Microsoft Windows 8 OS will be able to work on the ARM architecture too (for the first time not only on Intel).

The second trend is the transfer of a significant part of the calculations from the central processor to the graphics core. This topic is more related to the field of parallel computing.

Another trend is the growth of the mobile device market. It received the greatest acceleration last year with the advent of the iPad. At first, however, it seemed that this device was purely consumer and it would not be applicable in the corporate sector. However, it turned out that it is quite suitable for solving many problems.

In the CAD sector today, many employees are mobile - working on the road, at remote construction sites, moving around the country, working at home. (All this requires a handy mobile device.)

One way or another, abroad that every employee of the engineering service will soon have a tablet, today they speak as a fait accompli. Apple IOS mobile platforms attractive for developers have already appeared and android google, as well as a significant number of CAD applications for them.

Now it is very difficult to say whether the keyboard and mouse will leave our arsenal in ten years. But the fact is that interfaces focused on working with multi-touch screens (finger-based) are clearly gaining popularity. In mobile devices, they have almost become the standard. Today it is quite clear that this interface is more than suitable for information consumption. Whether it is just as good for its creation, for working with CAD, is still difficult to say. There is still not enough technological base for a mass transition to such interfaces. Now there are simply no large enough multi-touch panels on the market with the necessary resolution for CAD.

The CAD market is very conservative. Even replacing one such system with another within the framework of work on one project is a rather difficult task. What can we say about a serious paradigm shift, interfaces, CAD generations. Therefore, this market is clearly not one of the leaders in the technological race - there is development, but obviously not as fast as we would like. However, in the next decade, engineers who have grown up in the era of the Internet, new technologies and mobile devices will come to enterprises, and one way or another they will actively bring elements of their culture to the market.

CAD in construction

Digitalization of business has affected all its industries. In the last decade, solutions for the design, engineering and construction of industrial facilities have been booming. From Soviet drawing boards, designers came to 3D modeling. What digitalization means for this segment, how to help the team work in a single space and why it is not yet possible to completely get rid of paper media, Alexey Lebedev, CEO of AVEVA, helped to understand.

CAD system(computer-aided design computer-aided design support) is a computer-aided design system designed to perform design work using computer technology, and also allows you to create design and technological documentation for individual products, buildings and structures.

Usually an abbreviation CAD considered to be the standardized English equivalent of the term CAD. However, the concept of CAD is not a complete equivalent of CAD as an organizational and technical system: for example, in GOST 15971-90 this phrase is given as a standardized English equivalent of the term "computer-aided design". The term CAD in English can also be translated as CAD system, automated design system, CAE system.
A number of foreign sources establish a certain subordination of the concepts of CAD, CAE, CAM. The term CAE is defined as the most general concept, including any use of computer technology in engineering activities, including CAD and CAM. The term CAx (computer-aided technologies) is used to designate the entire spectrum of various automation technologies using a computer, including CAD tools.

The main purpose of creating CAD- increasing the efficiency of the work of engineers, due to the automation of work at the stages of design and pre-production. So, thanks to CAD, it is possible to achieve:

Reducing the complexity of design and planning;
- reduction of design time;
- reducing the cost of design and manufacture, reducing operating costs;
- improving the quality and technical and economic level of design results;
- reducing the cost of full-scale modeling and testing.

As input information, CAD uses the technical knowledge of specialists who enter design requirements, refine results, check the resulting design, change it, etc.
The computer-aided design system is implemented as a set of application programs that provide design, drawing, three-dimensional modeling of structures, flat or three-dimensional parts.
As a rule, modern CAD systems include modules for modeling a three-dimensional three-dimensional structure (parts) and designing drawings and text design documentation (specifications, sheets, etc.).

CAD classification according to GOST 23501.108-85:

Type / variety of design object
- complexity of the design object
- level of design automation
- complexity of design automation
- the nature of the issued documents
- number of issued documents
- number of levels in the technical support structure

Classification of CAD (or CAD subsystem) according to the intended purpose:

CAD (computer-aided design/drafting) - computer-aided design tools, in the context of this classification, the term means CAD tools designed to automate two-dimensional and / or three-dimensional geometric design, create design and / or technological documentation, and general-purpose CAD.
- CADD (eng. computer-aided design and drafting) - design and creation of drawings.
- CAGD (English computer-aided geometric design) - geometric modeling.
- CAE (English computer-aided engineering) - means of automation of engineering calculations, analysis and simulation of physical processes, carry out dynamic modeling, verification and optimization of products.
- CAA (computer-aided analysis) - a subclass of CAE tools used for computer analysis.
- CAM (English computer-aided manufacturing) - means of technological preparation for the production of products, provide automation of programming and control of equipment with CNC or GAPS (Flexible Automated Production Systems)). The Russian analogue of the term is ASTPP - an automated system for technological preparation of production.
- CAPP (eng. computer-aided process planning) - automation tools for planning technological processes used at the junction of CAD and CAM systems.
Many computer-aided design systems combine the solution of problems related to various aspects of CAD/CAM, CAD/CAE, CAD/CAE/CAM design. Such systems are called complex or integrated.

Generally accepted international classification of CAD/CAM/CAE systems:

Drawing-oriented systems, which first appeared in the 70s. (and have been successfully used in some cases so far).

Systems that allow you to create a three-dimensional electronic model of an object, which makes it possible to solve the problems of its modeling up to the moment of manufacture.

Systems that support the concept of a complete electronic description of the object (EPD Electronic Product Definition). EPD is a technology that enables the development and maintenance of an electronic information model throughout the entire life cycle of a product, including marketing, conceptual and detailed design, process preparation, production, operation, repair and disposal.

CAD abbreviation in modern technical, educational literature and state standards stands for "Computer-aided design system", although more closely corresponds to the abbreviation CAD decoding "System of automation of design work", but it is more heavy for perception and is used much less often. You can often hear the wrong interpretation - "Automatic design system", which is inherently erroneous, since the concept of "automatic" implies the independent operation of the system, without human intervention, and in CAD, part of the functions is performed by a person, and only certain design operations and procedures are automatic. Not quite correct interpretation "Software tool for design automation", because it is too "narrow": of course, at present, CAD is often understood only as application software for design activities. However, in domestic literature and state standards, CAD is defined as a more capacious concept, including not only software tools.

CAD systems are used to perform a variety of design procedures using computer technology. Also, with the help of such software, a technological one is created for individual buildings, products or structures. Modern CAD systems are used in a wide variety of areas of activity of a modern person, and almost each has its own unique type of such utilities.

What it is?

Often the abbreviation CAD is considered to be the standard English equivalent of the term CAD, but in fact this is not entirely true. CAD systems cannot be considered as a full-fledged analogue of CAD as an organizational and technical system, since GOST gives this phrase as a standardized English equivalent of the term "computer-aided design". Thus, the term CAD is translated into English more like a CAE system, but a number of foreign sources indicate that the term CAE is a generalized concept that includes the use of any computer technology in engineering work, including also CAM and CAD.

Why is this needed?

CAD systems are mainly used to maximize the efficiency and productivity of engineers through full automation of design and further production preparation. Thus, due to their use, the following advantages are achieved:

  • design time is significantly reduced;
  • the amount of labor required for planning and design is reduced;
  • the overall cost of manufacturing and design is significantly reduced, which directly affects operating costs;
  • increasing the technical and economic level, as well as the quality of the results of the design work;
  • reduction of costs required for testing and full-scale simulation.

As input, modern CAD systems use various technical knowledge of experts who refine results, introduce various design requirements, check the resulting design, modify it, and many other things.

The implementation of the computer-aided design system is carried out as a set of applied utilities, with the help of which the design is provided, as well as further drawing and three-dimensional modeling of structures or volumetric and flat parts.

In the overwhelming majority of cases, CAD systems include modules for modeling three-dimensional structures, as well as drawing up drawings and various design text documentation.

They are classified mainly according to several parameters:

  • variety and type of the object in question;
  • level of automation of the design procedure;
  • the complexity of the created object;
  • the complexity of the automation process;
  • the number of documents used;
  • the nature of the documents used;
  • the total number of levels that will be present in the technical support structure.

Special purpose

Depending on what tasks of CAD systems are implemented, they are divided into several groups:

  • Automation of three-dimensional or two-dimensional geometric design, as well as the creation of various technological or design documentation.
  • Design and further creation of drawings.
  • Conducting geometric modeling.
  • Automation of various engineering calculations, dynamic modeling, as well as analysis and simulation of physical processes with subsequent verification and optimization of products.
  • A subclass of CAE tools used for computer analysis.
  • Tools designed for the technological preparation of the production process of various products, which allows for the automation of the programming procedure and further control of equipment with GAPS or CNC.
  • Tools designed to automate the planning processes of various technological processes, used at the junction of CAM and CAD systems.

Most computer-aided design systems can combine the solution of various tasks that relate to different aspects of design - this is a complex or integrated computer-aided design (CAD) system.

Commonly accepted international classification

Modern classification divides them into several categories:

  • drawing-oriented systems, which first appeared in the seventies of the last century, but can still be used in some situations;
  • systems that create three-dimensional electronic models of objects, due to which it becomes possible to solve various problems associated with modeling up to the production procedure;
  • systems that support the concept of a complete electronic description of the object.

The latter type is a technology that provides the development and subsequent support of information electronic model throughout its life cycle, including conceptual and detailed design, full marketing, production, technological preparation, operation, as well as disposal and repair.

In modern technical and educational literature, as well as various state standards, the abbreviation CAD is interpreted as "Computer-aided design system", but at the same time, the concept of "Design work automation system" most accurately corresponds here, but it is more difficult to perceive, therefore it is an order of magnitude less common. . It often happens that when designing in CAD systems, one may notice an incorrect interpretation of "CAD", although in fact this is inherently wrong. Do not forget that the concept of "automatic" provides for a completely independent operation of the system without the need for any human participation, while CAD still requires the performance of some tasks by the person himself, and full automation refers only to certain procedures and operations. .

Not entirely true is also such a thing as "Computer-aided design software", as it can be called too narrowly focused. Of course, at the moment, CAD is considered exclusively as an application software necessary for carrying out design activities, but in fact, in the domestic literature and various state standards, CAD is considered as a more voluminous concept, which includes not only software tools.

CAD in dentistry

The overwhelming majority of modern dental clinics use CAD. CAD-systems in dentistry are used for the production of high-quality dentures, for more than ten years they have been used for the manufacture of abutments for implants, crowns and all kinds of prostheses, all of which are of excellent quality and high accuracy. The essence of this technology lies in the fact that initially a three-dimensional modeling of the created structure is carried out on a computer, and only then, using the design model, they are manufactured on a milling block.

Thus, dentists receive a lot of benefits through the use of CAD technology in their work. CAD systems in dentistry are most often used as follows:

  • first, the doctor takes an impression, which is then sent to the laboratory;
  • after delivery, the cast is placed in a specialized scanner that creates a model of the future product;
  • the CAD system comes into play: the 3D model is converted into a specialized file that will serve as a data source for the milling unit;
  • using the resulting file, a frame is produced on a milling block from a special blank made of zirconium oxide;
  • in the end, the resulting frame is carefully covered with ceramic mass and baked.

CAD/CAM systems in dentistry make it possible to produce crowns from zirconia, which differ from metal-containing products in a number of advantages. By themselves, these products practically do not have any differences in color from natural teeth, since the choice of shade is carried out even during the production of the frame. Next, the frame is carefully covered with a special ceramic mass, which has a translucent and translucent structure, and also includes enough wide range colors, thanks to which it is possible to make crowns similar to natural teeth.

By itself, it is highly biocompatible, even when compared with precious metals, and is a hypoallergenic material, which has been confirmed in a number of scientific clinical studies. However, in fact, crowns based on zirconium oxide frameworks are far from the only type of products for the manufacture of which CAD / CAM systems are used. CNC-machine based on such technologies makes it possible to produce:

  • various bridge prostheses;
  • individual abutments.

In addition to the already mentioned zirconia, a wide variety of materials can be used in the manufacturing process, including plastic, wax, cobalt and titanium, chromium.

What are the benefits?

These technologies provide benefits such as:

  • the highest possible manufacturing accuracy with minor deviations;
  • full automation of production processes, which almost completely eliminates the possibility of errors;
  • the possibility of using a wide range of materials;
  • the possibility of carrying out procedures for modeling and manufacturing products in different places;
  • ultimate performance of any ongoing processes.

CAD in mechanical engineering

The CAD-system (T-FLEX CAD and others) has found a fairly wide distribution in the field of mechanical engineering, which differs in three levels - lower, middle and upper. Such a division appeared at the turn of the eighties and nineties of the last century.

The lower level includes low-cost CAD/CAM/CAE systems that are mainly focused on 2D graphics, that is, they are mainly aimed at ensuring the automation of drawing work. Personal computers were used as light CAD systems, which already at that time were significantly inferior in functionality to full-fledged workstations.

Top-level systems, or, as they are commonly called, heavy CAD, were designed to be used on all sorts of mainframes or workstations. Such systems turned out to be much more versatile, but at the same time they had a rather high cost, focusing mainly on surface and solid modeling. The design of various drawing documentation in them is often carried out through the preliminary development of special geometric three-dimensional models. After that, systems in which the 3D modeling function was limited exclusively to solid models, that is, occupying an intermediate position between heavy and light, received their own, average level.

To date, the development of CAD has already led to the fact that special surface modeling tools have begun to appear in most middle-level systems, and the functions available for use in personal computers have also become acceptable for modern top-level systems. Due to this, even those principles have changed, according to which the distinction between medium and heavy systems was previously made. Modern heavy-level CAD systems are now called CAE / CAD / CAM / PDM, that is, those that simultaneously include features such as:

  • technological and design design;
  • engineering analysis;
  • project information management;
  • extended composition of special software modules.

In contrast, modern mid-range systems are usually called mainstream, mid-range, or simply serial.

Systems of one level can be called by functionality approximately equivalent, since some new achievements that appear in a certain software and methodological complex will soon be implemented in new versions of others. In CAD of large companies, it is quite common to combine several systems of different levels at the same time. Often this is due to the fact that almost all design procedures can be carried out on medium and low-level CAD systems, and besides, heavy ones are too expensive. It is for this reason that enterprises purchase licenses of top-tier software in a rather limited amount, and the vast majority of today's customer bases are provided by lower and middle tiers.

At the same time, it often happens that CAD / CAE systems may have certain problems in terms of exchanging information with each other, but such troubles are solved through the use of special formats and languages ​​\u200b\u200baccepted in CALS technologies, although to ensure undistorted transmission of geometric data through intermediate unified languages ​​have to overcome some difficulties.

Structure

Like any other complex systems, CAD includes several subsystems that can be design or maintenance.

The first are directly involved in the implementation of a variety of design work. As an example of these, one can cite subsystems for three-dimensional geometric modeling of various mechanical objects, circuit analysis, creation of design documentation, or tracing of printed circuit board connections.

Servicing subsystems are intended to ensure the normal performance of designers, and their combination is often called the CAD system environment among specialists. As typical service subsystems, design data management bases, various subsystems for the development and subsequent maintenance of CASE software, as well as training ones designed to facilitate the development of technologies implemented in CAD by users, are often used.

Structuring according to various aspects has allowed the emergence of types of CAD software, which today there are only seven:

  • technical, which includes various;
  • mathematical, combining all kinds of mathematical methods, algorithms and models;
  • software, which is a CAD computer program;
  • informational, which includes databases, management systems for these databases, as well as many other information used in the design process;
  • linguistic, expressed in the form of languages ​​of communication between computers and designers, languages ​​of data exchange between CAD hardware and programming languages;
  • methodical, which includes all kinds of design technologies;
  • organizational, executed in the form of job descriptions, staffing tables and other documentation, with the help of which the regulation of the work of design enterprises is carried out.

It should be noted that the entire set of information that is used in the design process is called the CAD information fund by specialists. The database is an ordered set of information that reflects the various characteristics of objects and their relationship in a certain Access to the database for studying, recording and subsequent correction of data is carried out through the DBMS, and the combination of DBMS and DB is commonly called BnD, that is, a data bank.

Classification

CAD / CAM design systems are classified according to a number of criteria, such as application, intended purpose, scale (how comprehensively the tasks are solved), as well as the nature of the underlying subsystem.

By applications, among the most popular and representative, it is worth highlighting the following CAD groups:

  • used in the field of general engineering (due to which they are usually called machine-building);
  • used in the field of radio electronics;
  • used in the field of construction and architecture.

In addition, there is also a fairly large number of specialized systems, either allocated in the listed groups, or representing a completely independent branch of the classification. As an illustrative example, CAD of large integrated circuits, electrical machines, aircraft and a number of others can be cited.

Separate software and methodological complexes differ in scale, including a complex for testing the strength of various mechanical products according to the finite element method or a complex for testing electronic circuits, as well as systems with a unique architecture of not only software, but also hardware.

Base subsystem

Here are the following types of CAD:

  • Based on the subsystem of geometric modeling and computer graphics. Such CAD systems are mainly focused on various applications in which design is the main design procedure, that is, a clear definition of spatial forms, as well as the relative position of objects. That is why this group includes many CAD systems from the field of mechanical engineering, based on graphics cores. Nowadays, it is quite common to use unified graphics cores.
  • DBMS based. They are mainly focused on those applications in which it is possible, by carrying out relatively simple mathematical calculations, to process a sufficiently large amount of information. They are often found in technical and economic applications, such as business plan design, but they are also often used in the design of large objects, such as control panels in automatic systems.

In addition, there are also complex CAD systems, which include subsystems of all previous types. As typical examples of such complex systems, it is worth citing software that is actively used in modern mechanical engineering, or CAD LSI. The latter includes a DBMS and various subsystems for designing components, functional and logical circuits, crystal topology, as well as tests for analyzing the suitability of manufactured products. In order to ensure the normal management of such complex programs, it is customary to use specialized system environments.
