Free drawing software, what to choose?

2016-06-15 08_16_19-drawing Good hour!

There are a lot of drawing programs now, but most have a significant drawback – they are not free and cost very decently (some more than the average salary in the country). And for many users, the task of designing a complex three-dimensional part is not worth it – everything is much simpler: print the finished drawing, correct it a little, make a simple sketch, sketch an electrical circuit, etc.

In this article I will give several free drawing programs (in the past, with some of some, I had to work closely myself), which are excellent for these cases …

1) A9CAD

Interface: English

Platform: Windows 98, ME, 2000, XP, 7, 8, 10

Developer site:

2016-06-15 08_27_26-Main window A9CAD

A small program (for example, its distribution kit weighs several times less than AucoCad!) That allows you to create fairly complex 2-D drawings.

A9CAD supports the most common drawing formats: DWG and DXF. The program has many standard elements: circle, line, ellipse, square, leaders and dimensions in drawings, lay out drawings, etc. Perhaps the only drawback: everything is in English (however, many words will be clear from the context – a small icon is shown opposite all words in the toolbar).

Note. By the way, on the developer's website (, among other things, there is a special converter that allows you to open drawings made in AutoCAD (versions supported: R2.5, R2.6, R9, R10, R13, R14, 2000, 2002, 2004, 2005 and 2006).

2) nanoCAD

Developer site:

Platform: Windows XP / Vista / 7/8/10

Language: Russian / English

2016-06-15 08_37_21-nanocad-main window

Free CAD system that can be used in a wide variety of industries. By the way, I want to warn you right away, despite the fact that the program itself is free – additional modules for it are paid (in principle, they are unlikely to be useful for home use).

The program allows you to freely work with the most popular drawing formats: DWG, DXF and DWT. By its structure of the arrangement of tools, sheet, etc., it is very similar to the paid analogue of AutoCAD (therefore, changing from one program to another is not difficult). By the way, the program implements ready-made standard shapes that can save you time when drawing.

In general, this package can be recommended both for experienced draftsmen (who probably have known about it for a long time?), And beginners.

3) DSSim-PC


OS type Windows: 8, 7, Vista, XP, 2000

Interface Language: English

2016-06-15 08_48_19-DSSim-PC

DSSim-PC is a freeware program for drawing electrical diagrams in Windows. The program, in addition to allowing you to draw a diagram, allows you to test the power of the circuit and watch the distribution of resources.

The program has a built-in circuit control editor, line editor, scaling, utility curve graph, TCC generator.

4) ExpressPCB

Developer site:

English language

OS Windows: XP, 7, 8, 10

2016-06-15 08_56_00-Expresssch main window

ExpressPCB – This program is intended for computer-aided design of microcircuits. Working with the program is quite simple, and it consists of several steps:

  1. Selection of components: a step in which you have to select various components in the dialog box (by the way, thanks to special keys, their search in the future is greatly simplified);
  2. Placement of components: use the mouse to place the selected components on the diagram;
  3. Adding loops;
  4. Editing: using standard commands in the program (copy, delete, paste, etc.), you need to modify your microcircuit to 'perfection';
  5. Ordering a microcircuit: in the last step, you can not only find out the price of such a microcircuit, but also order it!

5) SmartFrame 2D


2016-06-15 09_56_00-simulation example

Free, simple and at the same time powerful program for graphic modeling (this is what the developer claims about his program). Designed for modeling and analysis of flat frames, spans, various building structures (including multi-loaded ones).

The program is focused primarily on engineers who need not only to model the structure, but also to analyze it. The interface in the program is quite simple and intuitive. The only drawback is that there is no support for the Russian language …

6) FreeCAD

OS: Windows 7, 8, 10 (32/64 bits), Mac and Linux

Developer site:

2016-06-15 10_01_32-bearing in freecad

This program is intended primarily for 3-D modeling of real objects, of almost any size (do the limitations apply only to your PC?).

Each step of your modeling is controlled by the program, and at any time it is possible to go into history to any change that you made.

FreeCAD is a free, open source program (some experienced programmers add extensions and scripts for it themselves). FreeCAD supports a truly huge number of graphic formats, for example, some of them: SVG, DXF, OBJ, IFC, DAE, STEP, IGES, STL, etc.

However, the developers do not recommend using the program in industrial production, since there are some questions about testing (in principle, a home user is unlikely to face questions about this …).

7) sPlan


Language: Russian, English, German, etc.

OS Windows: XP, 7, 8, 10

2016-06-15 10_19_05-splan - a diagram drawn in the program

sPlan is a simple and easy to use program for drawing electronic circuits. With its help, you can create high-quality blanks for printing: there are tools for layout of the diagram on a sheet, a preview. Also in sPlan there is a library (quite rich), which contains a large number of elements that you may need. By the way, these elements can also be edited.

8) Circuit Diagram

OS Windows: 7, 8, 10


English language

2016-06-15 10_31_00-electrical diagram

Circuit Diagram is a free program for creating electrical circuits. The program has all the necessary components: diodes, resistors, capacitors, transistors, etc. To enable one of these components – you need to do 3 mouse clicks (in the literal sense of the word. Probably no utility of this kind can boast of such a thing)!

The program keeps a history of changes in the scheme, which means that you can always change any of your actions and return to the original state of work.

You can transport the finished schematic diagram in formats: PNG, SVG.


I remembered one anecdote on the topic …

A student draws a drawing at home (homework). Her father (an old-school engineer) comes up and says:

– This is not a drawing, but a daub. Let me help, will I do everything right?

The girl agreed. It turned out very neatly. At the institute, a teacher (also with experience) looked and asked:

– How old is your dad?

– ???

– Well, he wrote the letters according to the standard of twenty years ago …

I finish this article on the sim. For additions on the topic – thanks in advance. Happy drawing!
