Convert AutoCAD Objects to AutoCAD P&ID Components or Lines
You can identify AutoCAD objects as AutoCAD P&ID components or lines by converting the objects.
You can also add the converted object to the tool palette for use in the current project.
Convert an AutoCAD Object to a P&ID Component
An AutoCAD block or a group of AutoCAD lines is converted to a specific class definition in the P&ID schema. For example, you can convert a group of AutoCAD lines to a component of the “vessel” class definition.
This group of lines is converted into a single AutoCAD P&ID component. It contains the same data and graphical properties as an original AutoCAD P&ID component. The vessel is referenced in the Data Manager and in relevant reports (such as an Equipment List report).
In addition, the converted object has the same grip behavior and dynamic behavior as AutoCAD P&ID components.
Convert an AutoCAD Object as a P&ID Schematic Line
You can convert AutoCAD lines and polylines (including splines or polylines with arcs) into line class definitions that are recognized as P&ID data. Converting an AutoCAD line adds a record for that line in the Data Manager, and includes it in reports. You can specify P&ID line properties such as size, service, and spec.
NoteAn AutoCAD line that is converted to an AutoCAD P&ID line does not have the same dynamic behaviors of P&ID schematic lines. For example, a converted line does not automatically break when inline components are inserted in the line. It does not have flow direction properties.
Once you convert objects to P&ID components or lines, you can add the converted objects to a P&ID tool palette. The object becomes a tool on the tool palette, and can be placed in project drawings like any other P&ID tool.
You should understand the following when using converted objects as tools on the tool palette:
- The drawing file that contains the converted object must be saved to the current project.
- The converted object is available for all drawings in the current project, but only on the workstation where it was created.
- Converted objects that become part of your tool palette are not added to the project components and lines.

While teaching myself AutoCAD P&ID over the summer break I ran into some issues with inline blocks and database access. This is just a quick tutorial covering how to import a symbol/block into AutoCAD P&ID’s database and access functions like scaling on insert, inline symbols/blocks (Join type), auto block nozzles and general style properties.
Firstly, I should mention that it’s a good idea to maintain a database of symbols that you have created or acquired. Personally I use a DWG file that has different sections for pumps, blowers, instruments etc. The DWG file is also part of a project that houses the individual blocks and their design stages. Having everything in one place can really help when moving jobs or changing projects, so it’s something to consider if you plan on using AutoCAD P&ID in the future.
Step 1: Using a block
As I mentioned above, I use a DWG file that houses all my blocks, so for the purposes of this post I will be using a general blower from my block database. If you are unsure how to design or use a block, then you will need to brush up on the process before continuing.

Firstly you may need to create the block or symbol that you intend on importing. Before importing, it’s good practice to finalise the properties and parameters. Once you have created the block and are happy with its properties, save the drawing file.
Step 2: Accessing project setup (database)
In the command prompt type “PROJECTSETUP”. Alternatively in the project manager, right click the current project tree and select properties.

Step 3: Choosing a P&ID class definition
Open the tree in the following order:
P&ID DWG Settings > P&ID Class Definitions > [choose item or group]
In my case a general blower: P&ID DWG Settings > P&ID Class Definitions > Engineering Items > Equipment > Blowers > General Blower

In my case a general blower: P&ID DWG Settings > P&ID Class Definitions > Engineering Items > Equipment > Blowers > General Blower
Step 4: Adding a symbol/block (Case settings)
Once you have selected the type of item or group that your block fits under, click the “Add Symbols” button. Click the browse button and navigate to your saved drawing containing the block from Step 1. Once you have opened the file a list of available blocks from the file will be presented. Navigate to the block that you want to import and click “add”. Then click “next”.

Step 5: Edit Symbol Settings
To progress any further you will first need to name you symbol/block. At this stage you can set a number of properties that effect how the block will interact with your drawing.

If you require the block to be inline or within the stream line, make sure the joint type is set to “Inline”. To set an automatic nozzle or flange (appears on insert), select an option for “Auto Nozzle”. Other features are also available like scale on insert, the scaling mode, rotation or mirror upon insertion, prompt for annotation when inserting and a bunch of style properties like linetype, layer selection and color. Once you have finalised all the properties click “finish”.
Step 5: Editing block properties
Step 6: Editing the Symbol/block properties & adding to the tool palette
A number of different inputs are available for object information, this should be filled out if you are using AutoCAD as a database. You can also edit the tag layout/format and the annotation tag type.

Once you have finished editing the block properties, click “Add to Tool Palette” (you can change the block symbol location later by clicking and dragging the symbol to a different tab within the palette). You can also change the symbol or add more symbols to the class by clicking “Add Symbol”.
If you are happy with the symbol click apply and ok.

Step 7: Inputting your symbol
Firstly, check if your symbol is in the correct class. If you find it is not, simply click and drag the symbol to a different tab within the palette.

At this stage you should be able to input the new block/symbol into your P&ID. If you experience any problems you can always go back and edit the class settings by following the Project Setup tree and the method above.
