P&ID symbology in Plant 3D

Know your symbols-learn how different standards can affect the appearance of symbols in Plant 3D.


00:03

A process and instrumentation diagram (P&ID) represents the starting point for most plant designs,

00:11

and helps the engineer understand how a system is supposed to operate.

00:15

In AutoCAD Plant 3D, you should create these diagrams prior to actually adding modeling components, creating orthographic views,

00:23

or developing isometric spool drawings.

00:26

Your company may already have a symbol library, but is it using industry standards?

00:32

It's important to review your default content, then use what best reflects the standards you want to follow.

00:38

AutoCAD Plant 3D can help you be compliant, with symbology based on these standards: PIP (Process Industry Practices),

00:47

ISA (Instrument Society of America), ISO, JIS, and DIN (International, Japanese, and German standards organizations).

00:57

Start by setting the P&ID PIP workspace.

01:02

From the Tool Palettes, Equipment tab, select a horizontal centrifugal pump symbol.

01:07

To see the symbol more clearly, you can turn the grid off by pressing the F7 function key, or by selecting Grid on the Drawing Status bar.

01:16

Place it in the current drawing.

01:19

The Assign Tag dialog appears for you to tag the pump.

01:23

For this tutorial, click Cancel to skip the tag creation.

01:28

Note how the pump symbol appears.

01:31

This may not be the same symbol that you normally use to create your diagrams.

01:36

You can try another standard.

01:38

Switch to the P&ID ISA workspace.

01:43

From the Tool Palettes, Equipment tab, notice how the pump symbols look completely different from the PIP standards.

01:49

By changing workspaces and palettes based on specific standards, you can start with your library,

01:55

matching the most common standard to follow.

01:57

The symbology will match for different types of symbols, including:

02:02

Equipment, which includes pumps, tanks, and vessels;

02:05

Nozzles used for connections to equipment;

02:08

Instruments including control valves, flow meters, and instrument bubbles;

02:13

Inline components that are supported by a pipe run, such as valves and reducers;

02:19

And non-engineering items including connectors, flow arrows, and other symbology that doesn't contain any reportable data.

02:26

You can also edit the symbology, if needed.

02:30

P&ID content has intelligent data associated with the symbols, such as the part type and number, loop number, and pipe size.

02:39

This data is automatically associated with a database, and updates immediately as the data is changed
