What is free and what do I pay for?

The 79 symbols of the ANSI/IEEE 315 library as DWG files are free on this website and stay free. The Pro library with its 385 further symbols is sold as DWG files, and a palette licence includes them. You pay for the palette: browsing, search in nine languages, placing with attributes, carry-over, favourites. 12 symbols work without a key; the key unlocks all 464.

Can I try it before I buy?

Yes. Install the palette for free and use the 12 free symbols with every feature: placement, tags, attributes, search. Only the other symbols are locked.

On how many computers does a key work, and does it need internet?

An individual key works on two computers, an organisation key on as many as its people band. Internet is needed to activate. After that the palette checks the licence from time to time and keeps working for up to 14 days offline. To move to a new computer, free the old one in your account and activate again.

Which AutoCAD versions and systems are supported?

AutoCAD 2021 to 2027 on Windows 10 and 11, 64-bit. AutoCAD LT and Mac are not supported.

Yes, within 14 days of the purchase as long as the key has not been activated. See the refund policy.

Does it change my drawings? Will colleagues without the palette see them?

The symbols are inserted as ordinary blocks with their attributes. Your drawing is a normal DWG that opens on any computer, with or without the palette. Nothing is locked inside it.

I work for a company. Which licence do I need?

Choose the Organisation licence and the number of people who will use it; the price on the card is for one company. For a quote or a purchase order write to support@cadxchange.net.

About the palette

The palette puts the free ANSI/IEEE 315 library and the Pro library, 464 symbols together, in one panel next to your drawing. Normally every item means opening a file, inserting a block and filling in attributes by hand. The palette finds the symbol by name in your own language and places it with its attributes in a single click. Twelve symbols work for free, so you can start a drawing before you decide. One licence unlocks all 464 symbols and also includes the Pro library as DWG files.

What is inside

These are the 464 symbols the palette holds: the free library first, then the five sections of the Pro library, each shown as one sheet. You can see what you can place before you install anything. Click a sheet to enlarge it.

Open the library page with every symbol named

Click, place, repeat

Pick a symbol and it follows your cursor. Click to place it, and keep clicking to place more. Schematic symbols follow the drawing scale, so they fit the size of your diagram. Space or Enter turns it.

Attributes that carry over

Fill in the attributes once, for example the device and the rating. The next symbols you place arrive with them. You type what changes, not everything again.

Search in your own language

Type a part of a name in English, Chinese, German or any of the nine languages and the palette shows the matching symbols from every section. No need to know which chapter of the standard a symbol is in.

Nine languages

English, Simplified and Traditional Chinese, Japanese, Korean, German, French, Italian and Spanish. The palette follows the language of AutoCAD, or you pick one in the palette; the symbol names change with it.

Recent and favourites

The symbols you used last sit at the top, and the ones you star stay there. After a day of drawing, the twenty symbols you use are always at hand.

12 symbols free, 464 with a key

Twelve everyday symbols, contacts, pushbuttons and the basic switches, work in the palette without a key, with placement, attributes and search. The other symbols are visible with a lock; click one and the palette tells you how to unlock it. The drawing you make is a normal DWG that opens everywhere, with or without the palette.
