What is free and what do I pay for?

The 158 symbols as DWG files are free on this website and stay free. You pay for the palette: browsing, search in nine languages, placing with attributes, carry-over, favourites. 12 symbols work in the palette without a key; the key unlocks all 158.

Can I try it before I buy?

Yes. Install the palette for free and use the 12 free symbols with every feature: placement, 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.

I am a student or a teacher. How do I get the education offer?

Sign in with your school e-mail address and use the education button on the price card. The standard palette is free for one year, and a Pro palette is half price for one year. The steps are in the Students and teachers section above.

My school e-mail address is not recognised. What now?

The price card then shows a form: enter your school name or website. We check it and add the school, and you can claim again afterwards. Private addresses such as Gmail or Outlook cannot be used.

About the palette

The process equipment symbols are free to download as DWG files, and they stay free. The palette is for the moment after the download: you are drawing a process flow diagram with vessels, pumps, heat exchangers and columns, and every one means opening a file, inserting a block and filling in attributes by hand. The palette puts all 158 symbols in a panel next to your drawing, finds them by name in your own language, and places each one with its attributes in a single click. Twelve vessels and tanks work for free, so you can draw before you decide. The symbols are the pictorial edition of the process equipment library: machines drawn the way they look, with flanged nozzles.

What this palette can do

Set up the drawing in one click

Pick the drawing scale: standard layers for each kind of symbol, a text style and the scale settings are created, and every symbol you place goes onto its own layer.

Sheet frame and title block

Choose ISO, ANSI, ARCH or GB, the paper size and a title: the frame, the title block and a print-ready layout are made at once.

Connect pins

Free pins light up. Click one pin, then another, and a wire is drawn between them.

Junction dots

One click puts a dot on every junction where wires meet.

Parts list

Counts every symbol by type, with its tags, and exports the list as a CSV file.

Check drawing

Finds duplicate tags and coils without contacts, lists each problem on its own line and selects the symbols involved.

Equipment data

Opens the data of one piece of equipment (service, design pressure and temperature, material, volume, duty, flow, motor power) in a dialog and writes it into the block.

Resize

Sets the width and height of one piece of equipment (a vessel, a tank, a column): the symbol is stretched to the size you type and the text keeps its height.

Replace a symbol

Swap selected symbols for another one from the palette; position, rotation and tag are kept.

Click, place, repeat

Pick a symbol and it follows your cursor. Click to place it, and keep clicking to place more. The size follows your drawing scale, and the tag counts up by itself: P-101, P-102, P-103.

Attributes that carry over

Fill in the attributes once, for example the service. 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 group. No need to know which group 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.

Auto wirePro

Select a group of symbols and the wires between their pins are routed for you, with clean corners.

Number every wirePro

Numbers all wires in one pass, in order, with the prefix and start number you choose.

Wire listPro

Lists every wire with the two pins it connects and exports the list as a CSV file.

Nozzle tablePro

Lists the nozzles of every piece of equipment in the drawing (N1, N2 ...) with the nozzles they are wired to; open nozzles show an empty cell. Exports to CSV.

Renumber tagsPro

Renumbers the equipment tags of the drawing by prefix (P-, V-, E- ...) from left to right and top to bottom. A standby pair (P-101A/B) keeps its letters and moves together.

Standby pairPro

Copies a pump (or any equipment) as its standby: the tags become P-101A and P-101B, the data are copied.

Equipment sheetPro

Lists every tagged piece of equipment of the drawing with all its data fields (service, pressure, temperature, material, volume, duty, power ...) and exports it to CSV for Excel.

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.

What is inside

These are the 158 symbols of the free DWG library, shown as one sheet. The palette holds exactly these, so you can see what you can place before you install anything. Click the sheet to enlarge it.

Vessels and tanks 21
Reactors and agitators 18

Open the library page with every symbol named

12 symbols free, 158 with a key

Twelve vessels and tanks work in the palette without a key, with placement, attributes and search. That is enough to draw a first diagram and try the whole way of working. 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.

Install it free

Install the palette first; it is free, includes the 12 free symbols and opens every symbol and tool for 14 days. Buy the key when you want to keep them.
