Free AutoCAD telecom, radio, radar and data equipment marks (DWG): IEC 60417

About IEC 60417

IEC 60417 is the register of graphical symbols for use on equipment: every mark has a four-digit registration number, a title and a description of what it indicates. The marks are printed on, or shown by, the product, for example on a front panel, a label or a display. They are not the circuit symbols of IEC 60617.

The blocks are our own redrawings after the registered figures, not copies of the register, and the library is not certified. The registration number is stored in every block so that you can check a figure against the current edition of the standard, which is the authority.

Frequently asked questions

What is the difference between these marks and diagram symbols?

A diagram symbol (IEC 60617) stands for a component in a circuit. An equipment mark (IEC 60417) is printed on the product to tell the user what a control, a connector or a warning means. Use this library for front panels, labels, user interfaces and manuals.

How large should I draw a mark?

The blocks measure 20 mm on the reference square. The size on the product depends on the viewing distance and on the rules for your type of product, so scale the block to what your product standard or label specification asks for and write the value in SIZE_MM.

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.

Are marks for computers and copiers included?

Yes: memory disk, hard disk, disc media, computer network, mouse, keyboard, telephone line, copying and scanning marks (paper, toner, margins, overlay, scan mode, output tray) and the biometric marks for fingerprint, vein and face recognition.

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.
