Free AutoCAD machine, transformer, meter and symbol element symbols (DWG), IEC 60617 style

Machines, transformers, meters and symbol elements (IEC 60617): 78 ready-made AutoCAD blocks (DWG), free to download and use in your own projects, as a ZIP or one symbol at a time.

78 symbols as ready-to-use AutoCAD blocks, drawn after IEC 60617 (parts 2, 6, 8): winding connection marks (one to six phases, V, T, zigzag, double delta, polygon), transformer and current transformer variants (polarity dots, variable coupling, tap, several passages, pulse transformers), heat sources and thermoelectric and thermionic generators, the closed-loop controller, instruments (recording, maximum demand, power factor, phase, synchronoscope, oscilloscope, differential voltmeter, tachometer, thermometer, combined wattmeters, watt-hour meters with maximum demand), counters and the master clock, and the symbol elements (objects, propagation and energy flow, materials, effects, radiation, magnet, analogue and digital marks). Each block stores the entry number of the standard and the database number in invisible attributes.

Using AutoCAD 2017 or an earlier version? Download the 2010 format

Free to use and modify in your own projects, including commercial ones. The ZIP holds one plain DWG file in AutoCAD 2018 format and a README; no add-in needed. Provided as is, without warranty.

After you download

Use the symbols across a whole drawing set

A symbol only helps when every drawing uses the same version of it.

  1. Open the DWG and copy the blocks you need into your drawing, or drag them in from DesignCenter. Insert them at scale 1; the README in this ZIP gives the drawing unit and the insertion point of each group.
  2. When a symbol changes later, replace the old block with the new one in every drawing in one run with BlockCopy, instead of opening each file.
  3. To count symbols or list their attributes across many drawings, export them to Excel with BlockSync and build a pivot table from the result.

The tools are free for up to 10 files per batch; Pro removes the limit.

Attributes for parts lists

Devices carry a visible reference such as P1, T1 or U1 and invisible attributes: RATING, PART_NO, MANUFACTURER and REMARKS. Marks and small figures have a remarks field only, so they can be combined freely.

Because the data sit in attributes, you can export the devices of a project to Excel with BlockSync, build a list, check it and write the corrections back in one run, with preview and backup.

How to use the library

  1. Unzip the file and open the DWG. Copy the symbols you need into your plan, or drag the blocks in from DesignCenter (ADCENTER).
  2. The symbols are drawn at plotted size in millimetres on a 2.5 mm grid, the grid of the standard's pages: a boxed device is about 10 to 20 mm wide, a contact about 15 mm high. Insert them at the scale of your drawing, for example scale 2 on a 1:2 drawing.
  3. Meters are circles or boxes centred on their figure, with a visible reference P1. Current transformers are vertical with the primary at the top, and the secondary leaves to the right with the standard's slashes. Winding marks and symbol elements are small figures centred on themselves, meant to be combined with other symbols.
  4. Variants share the same body and differ by a mark or a detail. Edit the mark to make a variant that is not in the library.

About IEC 60617

IEC 60617 is the international standard for graphical symbols for diagrams, in many parts. This library holds figures of parts 2, 6, 8 that are not in the library “Common electrical symbols (IEC 60617)”, drawn after the standard's database.

These symbols are our own drawings after the figures of the standard. They are not copied from it, and the library is not certified against it. Check them against the standard, your company standard or your customer’s legend before you decide to use a symbol.

Frequently asked questions

Where are the ordinary motors, generators and transformers?
Motors, generators, the common transformers and the star and delta winding marks are in the library “Common electrical symbols (IEC 60617)”. This library has the variants and the less common ones.
Where are the other IEC 60617 symbols?
The standard is spread over several libraries on this site: common electrical symbols, power system single-line, semiconductors and tubes, binary logic elements, logic functions and analogue, telephone and sound, telecom transmission, relays and protection, machines and meters, and busbar trunking with cable television. Every library page lists the others.
Can I use the symbols in commercial projects?
Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.
What are the symbol elements for?
Objects, materials, propagation arrows, energy-flow marks and effects are the building blocks of IEC 60617 symbols. Put them inside or next to your own symbol when you need a figure that the library does not have.
Can I change a symbol or add attributes?
Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.
Where do I find a ready-made set of these symbols for AutoCAD?
AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.

Count the symbols and build a parts list

Because ratings and part numbers are attributes, the symbols of a whole project can be counted and listed without opening the drawings. Export the blocks to Excel, total them with a pivot table and write corrections back in one run, with preview and backup.

See how to count blocks with BlockSync
