Write in the comments what programs for creating circuits and designing electronic circuits do you use?

Drawing on paper is far from fun for everyone - it takes a long time, it’s not always beautiful, it’s hard to immediately correctly calculate the dimensions, and it’s inconvenient to make adjustments. All these problems are easily solved by the program for drawing diagrams. Most modern software products contain a library with a set of basic elements. From them, as from the constructor, the required configuration is assembled. Edits and corrections are made quickly, you can save different versions.

There are many drawing programs electrical circuits which can be used for free. Some of these are demo versions with limited functionality, some of them are full-fledged products. For designing a wiring diagram in an apartment or house, these functions are enough, but for professional use, a product with wider functionality may be required. For these purposes, paid options are more suitable.

Like any software, a diagram drawing program is rated for ease of use. The interface should be simple, convenient, functional. Then even a person without special computer skills can easily figure it out. But, nevertheless, the main factor is the sufficiency of functions for creating circuits of varying complexity. After all, even an inconvenient interface can be adapted, but the absence of some parts is more difficult to make up for.

A simple program for drawing diagrams VISIO

Many of us are familiar with Microsoft office products and Visio is one of the products. This graphics editor has a familiar interface for Microsoft products. Extensive libraries contain all the necessary element base, you can create circuit, wiring diagrams. Working in VISIO is easy: in the library (window on the left) we find the desired section, look for the required element in it, drag it to the working field, put it in place. The dimensions of the elements are standardized, they fit one with the other without problems.

Vision program for drawing diagrams - a clear interface

What's nice is that you can create diagrams to scale, which will make it easier to calculate the required length of wires and cables. What’s more good is that it doesn’t take much space on the computer’s hard drive, even not very powerful machines will “pull” this program for drawing diagrams. Also pleased with the presence of a large number of video tutorials. So there won't be any problems with learning.

Clear ProfiCAD

If you need a simple program for the design of electrical wiring - pay attention to ProfiCAD. This product does not require downloading libraries like most others. The database contains about 700 built-in elements, which are enough to develop a power supply scheme for an apartment or a private house. The available elements are also sufficient to draw up not too complex circuit diagrams. If an element is missing, it can be added.

The main drawback of the program for drawing ProfiCAD diagrams is the lack of a Russified version. But, even if you are not strong in English, it is worth a try - everything is very simple. In a couple of hours you will master everything.

The principle of operation is simple: in the field on the left we find the desired element, drag it to Right place diagrams, rotate to the desired position. Let's move on to next element. After completing the work, you can get a specification indicating the number of wires and a list of elements, save the results in one of four formats.

Compass Electric

A program with more serious functionality is called Compass Electric. It is part of the Compass 3D software. In it, you can not only draw a circuit diagram, but also block diagrams and much more. At the output, you can get specifications, purchasing lists, connection tables.

To get started, you need to download and install not only the program, but also a library with an element base. The program, explanations, help - everything is Russified. So there will be no problems with the language.

When working, select the desired section of the library, graphic images appear in a pop-up window. In it, select the necessary elements, drag them to the working field, setting them in the right place. As the scheme is formed, the data about the elements get into the specification, where the name, type and denomination of all elements are fixed.

The numbering of elements can be put down automatically, or maybe manually. The method is selected in the settings menu. You can change it during work.

QElectroTech

Another program for drawing circuits is QElectroTech. The interface resembles Microsoft products and is easy to work with. There is no need to download a library for this program, the element base is "built-in". If something is not there, you can add your own elements.

The finished scheme can be saved in the get format (for further work with it in the program) or as an image (jpg, png, svg, bmp formats). After saving, you can change the dimensions of the drawing, add a grid, a frame.

QElectroTech- free editor to create electrical circuits

This program has some drawbacks. The first is that inscriptions can be made in only one font, that is, if you need a drawing in accordance with GOST, you will have to somehow figure out how to change the font. The second is that the sizes of frames and stamps are set in pixels, which is very inconvenient. In general, if you need a program for drawing diagrams for home use, this is a great option. If compliance with the requirements of GOST is required, look for another.

123D Circuits Electronic Circuit Simulator

If you do not know how to draw a diagram on a computer, take a closer look at this product. 123D Circuits is online service, which allows you to create a not very complex circuit with the ability to create printed circuit boards. There is also a built-in simulator that simulates the work of the finished circuit. The function of ordering a batch of ready-made boards is available (for a fee).

Before you start, you need to register, create your profile. After that, you can start work. Multiple users can work on the same project using shared libraries. In the free version of the program, you can create an unlimited number of schemes, but they will be publicly available. In the amateur tariff ($12), five circuits can be personal, and there is also a 5% discount on the production of circuit boards. The Professional plan ($25) gives you an unlimited number of personal designs and the same discount on ordering boards.

The circuit can be drawn from the available components (there are not very many of them, but it is possible to add your own) or imported from the Eagle program. Unlike other programs, the 123D Circuits library does not contain schematic symbols of elements, but their mini copies. Interface with two side fields. On the right, the section of the library with the element base is displayed, on the left - part of the settings and the list of used elements. After the work is completed, the program itself generates circuit diagram, and also suggests the location of elements on the board (can be edited).

Everything seems to be fine, but 123D Circuits has serious drawbacks. First, the results of simulated work are often very different from real readings. The second - the functionality is small, it will not work to make a really complex circuit. Conclusion: Basically, this program is suitable for students and beginner radio amateurs.

Paid programs for drawing electrical circuits

Paid graphic editors there are many to create circuits, but not all of them are needed for “home” use or for work, but not directly related to design. Paying a lot of money for unnecessary features is not the smartest decision. In this section, we will collect those products that have received a lot of good reviews.

DipTrace - for PCB design

For experienced radio amateurs or those whose work is related to the design of radio products, the DipTrace program will be useful. It was developed in Russia, therefore it is completely in Russian.

It has very useful feature- it can develop a printed circuit board according to a ready-made scheme, and it can be seen not only in two-dimensional, but also in a three-dimensional image with the location of all elements. It is possible to edit the position of elements on the board, develop and correct the device case. That is, it can be used both for designing wiring in an apartment or house, and for developing some devices.

In addition to the program for drawing diagrams, you will also need to download a library with an element base. The peculiarity is that this can be done using special application— Schematic DT.

The interface of the program for drawing circuits and creating printed circuit boards DipTrace is convenient. The process of creating a scheme is standard - we drag the necessary elements from the library onto the field, expand them in the required direction and set them in place. The element currently being worked on is highlighted, which makes the work more comfortable.

As the scheme is created, the program automatically checks the correctness and admissibility of connections, the coincidence of sizes, compliance with gaps and distances. That is, all edits and adjustments are made immediately, at the creation stage. The created circuit can be run on the built-in simulator, but it is not the most difficult, so it is possible to test the product on any external simulators. It is possible to import a scheme to work in other applications or accept (export) an already created one for its further development. So the DipTrase circuit drawing program is a really good choice.

If needed printed circuit board- we find the corresponding function in the menu, if not - the scheme can be saved (it can be corrected) and / or printed. The DipTrace diagramming program is paid (there are different tariffs), but there is a free 30-day version.

SPlan

Perhaps the most popular program for drawing diagrams is SPlan. It has a well thought out interface, extensive, well structured libraries. It is possible to add your own elements if they are not in the library. As a result, it is easy to work, the program is mastered in a few hours (if you have experience with similar software).

The disadvantage is that there is no official Russified version, but you can find it partially translated by craftsmen (the help is still in English). There are also portable versions (SPlan Portable) that do not require installation.

One of the most "light" versions - SPlan Portable

After downloading and installing the program, you need to configure it. This takes a few minutes, the settings are saved on subsequent launches. The creation of schemes is standard - we find the desired element in the window to the left of the working field, drag it into place. The numbering of elements can be put down automatically or manual mode(selected in the settings). What's nice is that you can easily change the scale - by scrolling the mouse wheel.

There is a paid (40 euros) and free version. The free one disables saving (bad) and printing (you can bypass it by creating screenshots). In general, according to numerous reviews, it is a worthwhile product that is easy to work with.

Electricians no longer use compasses and T-square to manually compose a complex and intricate system of lines and cables. This is not only long and laborious, but also not always beautiful and clean. In addition, any person is prone to errors, this is especially noticeable when working with drawings: inaccuracy on paper translates into a real danger to the use of the electrical system by users. The design of electrical circuits became more accessible after the development of special programs for building and modeling electrical wiring in a house or apartment. In this article, we will talk about the need for CAD, the positive and negative aspects of the most popular of them.

Advantages of designing drawings on a computer

  • Circuit diagramming platforms are designed to make it easier to create accurate drawings. The machine will do the calculations for you based on the data you enter. Any product made in a good designer will be automatically tested.
  • Many software includes a diverse base. Ready-made layouts that you just need to add and customize. All elements in the library meet drawing standards. Using them in your work, you make your task easier and do not waste time re-drawing classic power grid blocks.
  • Advanced functionality makes the computer analog of a pencil and ruler much more ergonomic. No need to have a pile of paper drawings with different parts when you can click a couple of buttons in an electrical design program to compare different pages. Using new technologies, it becomes easier for an engineer to work: there is no need to draw a lot of drawings, on which only the indicators differ, the computer will do it for you. ZWCAD solves this problem by prompting the user to insert selected objects with various parameters from the properties palette.
  • It is very convenient to store the project in electronic form. It can be sent by mail to colleagues, finalized or corrected if necessary. There is no need to redraw the drawing. When the work is completed, the plan can be printed at any scale.
  • In any project, there are elements that do not require a creative approach. They are standard and uncomplicated, but also waste the developer's time. They come to help automatic systems CAD design. With them, all or part of the work will be done in a fraction of a second.
  • Any consumer will find their product. To draw up a simple wiring diagram for a house, a free version of the program for an electrician is suitable. Such software has less functionality and opens up more modest possibilities, but sometimes more is not required to complete a simple task. A specialist will also choose software for himself: with extensive resources and a technologically competent interface. The high cost of a product is not always an indicator of quality. Popular companies that occupy a high position among their peers inflate the price, yielding in a variety of properties to their younger competitors.
  • The quality of European standards remains, but the use becomes convenient for the average designer, because most of the new programs for creating electrical circuits offer an interface in Russian.
  • There are developments aimed at a specific specialty. The tools in them are selected for a specific activity, for example, for the construction of large buildings, industrial facilities or residential buildings. Some companies offer additional modules that expand the functionality of the standard package.
  • Many companies offer periodic updates, so once purchased a platform will remain relevant for many years.

When is the software suitable?

The program is needed for drawing, designing, drawing single-line power supply diagrams at home. It is a graphic design document. Its toolkit contains the elements included in the structure of the device and the contacts between them. Conventions make it easy to find and apply all the tools available during development. The drawing itself is part of the entire package of documents related to the project. It contains data for mounting, coordinating and controlling the device.

What stages is the program for drawing electrical circuits

It is indispensable at all stages of power supply:

  1. Drawing up a project. The model makes it possible to establish the components of the product being developed.
  2. Production process. The drawings show the device. Based on them, all stages of creating, installing and testing the system are calculated.
  3. Period of operation. If a defect appears or a breakdown occurs, thanks to the drawing, you can find the cause and understand how to eliminate it.

This is the main type of planning. It is usually used in the construction of simple projects. This method differs from other models in its ease of creation: the entire set of components necessary to supply electricity to consumers is displayed on it with several lines.

The main stages of project development using a program for creating, drawing, drawing electrical circuits:

  • The initial and most important stage is the collection and preparation of computational materials. Calculation accuracy is important.
  • If the system was in use, it is necessary to visually and technically diagnose the electrical system, study the characteristics and identify defects and breakdowns in the network. Based on the results of the inspection, you need to draw up an estimate of those parts that need to be replaced. These data are included in the report and taken into account in the design. If the entire electrical network requires reconstruction, the calculation has to be done again.
  • With the collected materials, you can proceed to the drawing. The safety of the owner and users of the premises depends on the correctness of this stage. The accuracy of execution can be assigned to specialized programs for the design of electricians.

ZWSOFT offers technical support for users of any version of ZWCAD. They will answer your questions related to the use of the software. The developer's site has articles and videos created to help customers.

  • The final step before the start of installation is the approval of the project in the operation service. If everything is approved, you can proceed with the installation.

Compliance with all the rules is fundamental when preparing a building for electrification. Depends on normal functioning of the entire power supply, the possibility long service life without repair and replacement of parts and, of course, the health and safety of consumers.

What programs for designing power supply systems exist

There are a number of platforms, among which there are paid ones and their free analogues. The basic functionality remains the same, but purchased software offers a number of additional tools. Let's talk about the most popular.

Autocad

Until recently, this product held a leading position in the construction systems market. Autodesk developed this software back in 1982, and it immediately gained popularity among engineers. The abbreviation AutoCAD in translation means "computer-aided design systems." It is a 2D or 3D modeling program. It is actively used by engineers of various industries. AutoCAD has been translated into 18 languages. Russian version fully adapted to the users of our country - the entire interface and tools are clear and accessible. And only the instruction is not adapted for Russian designers. During its long life, the company has developed dozens of versions, thousands of add-ons and supporting applications.


According to statistics, around the world, about 6,000,000 consumers use the capabilities of the AutoCAD service. Among all the functions, the 3D modeling system occupies a special place. Volumetric figures can be brought to life, thanks to the possibilities of three-dimensional printing. The promoted brand has both zealous supporters and critics. The former argue that all the disadvantages attributed to AutoCAD are only the result of an incomplete study of the platform and the inability to use its full potential.

The second finds negative sides:

  • The first is a conclusion from the statement of software adherents: if most engineers cannot understand the capabilities of the software, then its functionality is too difficult to transfer to the user.
  • It is often noted that AutoCAD graphics are not suitable for text editors.
  • The system does not recognize some drawings made in other software.
  • Numerous add-ons to AutoCAD often have an inconvenient interface.
  • Both supporters and opponents of the program agree with the last drawback - its price is too high. And even if we assume that the quality is correlated with the cost, the product does not become more accessible from this.

Reasons to look for other platforms:

Over the past 5 - 7 years, the position of popular software has fallen. Increasingly, engineers are looking for an analogue of foreign developers. This is due to the company's policy of compulsory licensing and high price for the product, according to users' opinions. Large companies are interested in finding the most profitable software for work.

The main search criteria are:

  • wide possibilities for design electronic systems, a similar feature set;
  • convenient and simple interface, understandable to both a specialist and an inexperienced user;
  • simplified licensing system;
  • reasonable price and flexible system of corporate discounts;
  • compatibility with projects made in other software;
  • the ability to purchase upgrades and additional modules that expand the classic basic set of functions.

QElectroTech

This is one of the free programs in Russian for drawing various electrical circuits: single-line, structural and hydraulic. It is easy to use thanks to a large library of ready-made layouts. Well suited for beginners and students who do not need a wide range of tools, but rather an easy design process. But due to the small variety of functions, the system is not suitable for serious, complex projects and for professional work.

Visio

Another product that competes with popular simulators. It is the most convenient in work: the creators competently approached the classification of elements. The division into groups made the details accessible, they are dragged onto the layout and stacked one on top of the other, as in the constructor. But the library of ready-made schemes is poorer than that of most programs. Another notable disadvantage is possible failure formatting when included from a different version or in a different format.

NanoCAD

An excellent domestic analogue of AutoCAD. It has decent functionality and a number of additional modules. The interface remains the same and is easily recognizable. Unlike a foreign product, it is convenient to work with layers - there is a function to delete one slice with data transfer to the previous one. This allows you not to multiply the tabs and not clutter up the drawing. But there are opinions according to which this development did not live up to expectations: it takes a long time to load and often works jerkily or reacts slowly, it works unstable. The disadvantages also include incomplete geometry editing, in particular, the impossibility of trimming splines and hatching.

ZWCAD - convenient CAD for electrical circuits

The development of ZWSOFT is a high-tech analogue of AutoCAD, which has the potential to surpass the first in manufacturability. ZWSOFT employees make the transition of consumers to new software easy and convenient. This is as follows:

  • Each customer is offered a free technical consultation. They will help you choose the right version, taking into account the capabilities of the consumer's equipment and the scope of the product.
  • Before buying, it is possible to test the platform by installing a fully functional version with a limited validity period.
  • The discount system is aimed at working with corporate clients: the simultaneous purchase of a whole package of licenses will cost several times cheaper than from competing companies.
  • The ZVKADA interface combines ease of use and versatility.
  • The platform has broad compatibility with other CAD formats. You can even integrate with third party applications, since files created in other editors are supported in ZWCAD.
  • It is easy to work in both 2D and 3D space.
  • The client will have access to regular updates and extensions, both paid and free.
  • The company offers a range of options, from the classic feature set to the professional package.

This program is ideal for both multi-stage design of the power supply system at the enterprise, and for the design of simple wiring diagrams in the apartment. Can be designed for different platforms, get used to and not pay attention to shortcomings. But in order to enjoy your work, you need high-quality and convenient software that meets all your preferences.

We use computers and virtual instruments more and more. It’s already not always desirable to draw diagrams on paper - it takes a long time, it’s not always beautiful and it’s difficult to fix. In addition, a program for drawing circuits can give a list of necessary elements, simulate a printed circuit board, and some can even calculate the results of its work.

Free Schematic Programs

There are many good free programs for drawing electrical circuits on the network. For professionals, their functionality may not be enough, but to create a power supply scheme for a house or apartment, their functions and operations will be enough. Not all of them are equally convenient, some are difficult to learn, but you can find several free programs for drawing electrical circuits that anyone can use, they have such a simple and intuitive interface.

The easiest option is to use a regular program Windows Paint, which is available on almost any computer. But in this case, you will have to draw all the elements yourself. A special program for drawing diagrams allows you to insert ready-made elements into the right places, and then connect them using communication lines. We will talk about these programs further.

A free program for drawing diagrams does not mean bad. In this photo, work with Fritzing

The program for drawing QElectroTech circuits is in Russian, and it is completely Russified - menus, explanations - in Russian. Convenient and intuitive interface - a hierarchical menu with possible elements and operations on the left side of the screen and several tabs at the top. There are also buttons quick access to perform standard operations - saving, printing, etc.

There is an extensive list of ready-made elements, it is possible to draw geometric shapes, insert text, make changes in a certain area, change direction in a particular fragment, add rows and columns. In general, the program is quite convenient with which it is easy to draw a power supply diagram, put down the names of the elements and ratings. The result can be saved in several formats: JPG, PNG, BMP, SVG, data can be imported (opened in this program) in QET and XML formats, exported in QET format.

The disadvantage of this program for drawing diagrams is the lack of a video in Russian on how to use it, but there are a considerable number of lessons in other languages.

Microsoft graphics editor - Visio

For those who have at least a little experience with Microsoft products, it will not be difficult to master the work in the Visio graphics editor (Visio). This product also has a fully Russified version, and with a good level of translation.

This product allows you to draw a diagram to scale, which is convenient for calculating the number of wires needed. A large library of stencils with symbols, various components of the circuit, makes the work similar to assembling a constructor: you need to find the right element and put it in place. So how to work in programs of this type many are accustomed to, the search is not difficult.

The positive aspects include the presence of a decent number of lessons on working with this program for drawing diagrams, and in Russian.

Compass Electric

Another program for drawing diagrams on a computer is Compass Electric. This is a more serious product that is used by professionals. There is a wide functionality that allows you to draw various plans, flowcharts, and other similar drawings. When transferring the scheme to the program, the specification and wiring diagram are formed in parallel, and they are all printed out.

To get started, you need to load the library with system elements. When you select a schematic image of one or another element, a window will “pop up” in which there will be a list of suitable parts taken from the library. A suitable element is selected from this list, after which its schematic representation appears in the indicated place of the diagram. At the same time, a designation corresponding to GOST with continuous numbering is automatically affixed (the program changes the numbers itself). At the same time, the parameters (name, number, denomination) of the selected element appear in the specification.

In general, the program is interesting and useful for developing device diagrams. It can be used to create a wiring diagram in a house or apartment, but in this case its functionality will hardly be used. And one more positive moment: there are many video tutorials for working with Compass-Electric, so it will not be difficult to master it.

DipTrace program - for drawing single-line diagrams and circuit diagrams

This program is useful not only for drawing power supply diagrams - everything is simple here, since only a diagram is needed. It is more useful for PCB design, as it has a built-in function for converting an existing schematic into a PCB trace.

To get started, as in many other cases, you must first load the element base libraries available on your computer. To do this, the Schematic DT application must be launched, after which the libraries can be loaded. They can be downloaded on the same resource where you will take the program.

After loading the library, you can start drawing the diagram. First, you can "drag" the necessary elements from the libraries to the working field, expand them (if necessary), arrange and connect them with communication lines. After the circuit is ready, if necessary, select the line "convert to board" in the menu and wait for a while. The output will be a finished printed circuit board with the arrangement of elements and tracks. You can also see it in 3D appearance finished board.

Free ProfiCAD program for drawing electrical diagrams

Free program for drawing diagrams ProfiCAD is one of the best options for the DIYer. It is easy to use, does not require special libraries on the computer - it already has about 700 elements. If there are not enough of them, you can easily replenish the base. The required element can simply be dragged onto the field, expanded there in the desired direction, and installed.

Having drawn a diagram, you can get a connection table, a bill of materials, a list of wires. Results can be obtained in one of the four most common formats: PNG, EMF, BMP, DXF. A nice feature of this program is that it has low hardware requirements. It normally works with systems from Windows 2000 and above.

This product has only one drawback - there is no video about working with it in Russian yet. But the interface is so clear that you can figure it out yourself, or watch one of the "imported" videos to understand the mechanics of work.

If you find yourself working with a diagram drawing program frequently, some paid versions are worth considering. Why are they better? They have wider functionality, sometimes more extensive libraries and a more thoughtful interface.

Simple and convenient sPlan

If you do not really want to deal with the intricacies of working with multi-level programs, take a closer look at the sPlan prolukt. It has a very simple and understandable device, so after an hour and a half of work you will already be able to navigate freely.

As usual in such programs, a library of elements is needed, after the first start they must be loaded before starting work. In the future, if you do not transfer the library to another location, the setting is not needed - the old path to it is used by default.

If you need an element that is not in the list, you can draw it, then add it to the library. It is also possible to insert extraneous images and save them, if necessary, in the library.

From other useful and desired functions- auto-numbering, the ability to change the scale of an element by rotating the mouse wheel, a ruler for a more understandable scaling. In general, a pleasant and useful thing.

Microcap

This program, in addition to building a circuit of any type (analog, digital or mixed), also allows you to analyze its operation. The initial parameters are set and the output data is obtained. That is, you can simulate the operation of the circuit under various conditions. Highly useful opportunity, because, probably, teachers and students love her very much.

The Micro-Cap program has built-in libraries that can be replenished using a special function. When drawing an electrical diagram, the product in automatic mode develops circuit equations, also performs calculations depending on the set denominations. When the value is changed, the output parameters change immediately.

A program for drawing power supply schemes and more - more to simulate their work

The ratings of the elements can be constant or variable, depending on various factors - temperature, time, frequency, the state of some circuit elements, etc. All these options are calculated, the results are given in a convenient form. If there are parts in the circuit that change their appearance or state - LEDs, relays - when simulating operation, they change their parameters and appearance due to animation.

The program for drawing and analyzing Micro-Cap circuits is paid, in the original it is in English, but there is also a Russified version. Its cost in professional version- more than a thousand dollars. The good news is that there is also a free version, as usual with limited features (smaller library, no more than 50 elements in the circuit, reduced speed). For home use, this option is quite suitable. It's nice that it works fine with any Windows system from Vista and 7 and above.

Drawing refers to the process of creating images of objects with the exact reproduction of their dimensions using a scale. Drawing electrical circuits requires compliance with the GOST symbols adopted to designate each element.

To create a document on a computer, software is needed - a graphic editor that converts the PC user's manipulations on the input device into a drawing. The created document can be saved electronically as a file and/or printed on paper in a specific format.

You can draw electrical circuits with any available graphic editor. However, special programs adapted for these purposes greatly facilitate routine work, allow you to use already prepared blanks. various elements from the library, quickly paste them to the right place, convenient to edit.

The novice user should be aware that drawing programs can be supplied and run:

1. free;

2. for money.

In the second variant functionality software have been greatly expanded. In addition, over the past decade, entire CAD systems have become popular among paid programs among design engineers. They not only automate the work, but also perform it very accurately. Due to this, they have a high cost.

However, among CAD programs, programs that are supplied free of charge began to appear. Their functionality, of course, is a little limited, but it allows you to create high-quality electrical circuits at the initial and intermediate level of design.

KOMPAS-3D program

This well-known development of Russian programmers from the ASCON company allows you to draw diagrams in one plane or engage in 3D modeling. It is used by students, teachers and engineers in many countries. The program has a clear interface and a set of tools convenient for drawing.

For use by various specialists, the graphic editor is replenished with additional modules. The development kit for creating electrical circuits has a large library.

The program works in rectangular Cartesian coordinates, using linear dimensions in millimeters and angular dimensions in degrees. The reference material built into the program is well presented and allows you to independently understand all the questions that arise.

Compass 3D is distributed on a paid basis, but manufacturers provide anyone with the opportunity to evaluate the work of the program for free for a month. For this purpose, you can download a demo version, which has some limitations.

The program of the famous company Autodesk has been constantly improved for about 30 years, it is considered the most functional for complex design work. Built into the graphical editor, the help explains in detail the features of the algorithms. However, there is a lot of information, and it is difficult to master it on your own.

It is best to use the advice of an experienced mentor to master drawing in it. Even with its help, to fully master all the functionality, it will take more than one month of painstaking work, but you do not need to master the 3D format to develop electrical circuits.

A feature of the program is the use of a polar coordinate system for calculations and work with vectors. When drawing, for the convenience of the user, information is displayed in a rectangular Cartesian system. This allows you to determine the location of a point in two measurement systems.

In addition to using information from an extensive library, you can create frequently entered images of objects in the form of macros, assign hot keys for them, and use object binding when displaying them on the monitor. This greatly speeds up the drawing process.

The program has numerous settings that require detailed study at the beginning, but in the future greatly facilitate the work.

Quite often, detailed electrical circuits on paper take up large dimensions. AutoCAD allows you to create drawings on sheets of different sizes. If earlier a plotter was required for printing, now you can get by with an ordinary printer. The program implements the possibility of dividing the drawing into its component parts and printing them on sheets of A4 paper, followed by gluing along the borders.

Microsoft Visio program

The name of the product indicates that the paid graphic editor belongs to a company that occupies a leading position in software development. There are great opportunities for creating charts, diagrams and their connection with data.

Users of Microsoft programs are familiar with this interface. For drawing electrical circuits, special templates on various topics have been created and placed in an accessible library.

A large number of tools are formed into groups and are conveniently configured for specific drawing conditions.

Microsoft Visio works in rectangular coordinates and is compatible with Word. Therefore, it can create graphic elements for insertion into text documents. This is convenient to use when writing instructions for the purpose of visual explanation of the material presented with diagrams and diagrams. The reverse insertion of texts and objects created in Word is also performed through the memory buffer.

Electrical circuits drawn in large sizes can also be printed not on a plotter, but on a printer in parts on sheets of A4 paper. As in AutoCAD, for this you need to set the print settings.

Here, too, you can create frequently used element designations as templates for use in further work. The program allows you to draw and draw relatively quickly.

Significantly facilitate the work and speed up the creation of high-quality diagrams in Visio, you can use special additional stencil libraries designed to create electrical diagrams power supply, modern devices of electroautomatics, electric drive and control. With the help of such component libraries, it is very easy to create professional circuits in accordance with standards.

Such kits for drawing electrical circuits will be useful, first of all, to electrical personnel involved in the design, installation, commissioning, repair and maintenance of electrical installations, as well as to everyone who needs to quickly and accurately draw an electrical circuit and arrange it in accordance with GOST.

CorelDRAW Technical Suite

A very powerful and expensive graphics program allows architects, designers and even fashion designers to perform a very wide range of work to produce three-dimensional images. You can use it to create electrical circuits. But at the same time, its capabilities will be greatly underestimated, which is not economically rational.

A9CAD 2.2.1

This is also an Autodesk product. It largely repeats the work of the famous AutoCAD, but lacks the 3D design function. Distributed for free.

The interface of the CAD program is adjusted to the familiar look Windows programs, and its size is 15.54 megabytes. This graphic editor supports files created in DWG formats and DXF, which are used as industry standards.

English language. The set of tools is quite extensive, modeled after AutoCAD. Image editing uses scaling, working with windows and layers, moving, inserting breaks, rotating, changing reflection, text overlay, color palette and other functions and styles.

With A9CAD 2.2.1, you can start drawing electrical circuits yourself.

There are many free graphic editors on the Internet. Only Autodesk, besides A9CAD, offers a few additional developments. To choose a program for drawing electrical circuits, you should evaluate your needs, capabilities and tasks.
