P&ID File Format

The .xml file specifies each piece of equipment and pipe or tube system to include in the routing assembly, and must adhere to the SolidWorks P&ID file format.

To view an example of the P&ID file format, double-click the sample P&ID xml file from the following location in C:\ProgramData or C:\Documents and Settings\All Users\Application Data, depending on your operating system:
SolidWorks\SolidWorks version\design library\routing\piping\pnid sample version.xml

P&ID Data

Attribute string values are optional unless otherwise noted. Required values and elements are indicated by *.

You can define multiple elements to model multiple pipelines in the routing assembly, but you cannot assign two pipelines with the same tag in separate routing assemblies.
<TubelineInfo>   Specifies a container element for tube fittings and connections.
Requires the closing element </TubelineInfo>.
You can define multiple elements to model multiple tubelines in the routing assembly, but you cannot assign two tubelines with the same tag in separate routing assemblies.

Equipment and Fittings

Attribute string values are optional unless otherwise noted.
Element Attribute Element or Attribute Description
<Equipment> * or <Fitting>*   Specifies the container element for a piece of equipment or fitting in the piping and instrumentation system.

<ID>* value* Defines a unique string value that identifies the piece of equipment or fitting.
<Tag>* value* Defines a unique string value for the equipment or fitting tag.
This value appears in the Piping and Instrumentation tab of the Task Pane.
<Description> value Defines a string value that describes the piece of equipment or fitting.
<PartNumber> value Defines a string value for a SolidWorks part number for the piece of equipment or fitting.
If you do not assign a part number, you can specify the library search with the <Type>, <SubType>, <Size>, and <Specification> elements.
<Config> value Defines a string value for the SolidWorks part configuration for the piece of equipment or fitting.
<Area> value Defines a string value for the equipment or fitting Area subtag.
<Type> value Defines a string value for the component type, for example, "tee" or "reducer".
If you do not assign a <Type> value, you are prompted to search for the file when the Select Component dialog box appears.
<SubType> value For valve part types, defines a string value for the subtype, for example, "gate" or "globe".
<System> value Defines a string value for the equipment System subtag, which assigns a name to the routing subsystem to which the piece of equipment or fitting belongs.
<Size> value Defines a string value for the equipment or fitting Size subtag, which specifies the nominal size. The size aids the database search when you do not specify the part number and configuration.
<Specification> value Defines a string value for the Specification subtag.
<Custom>  
Specifies the container element for custom attributes and values. Include the <CustomAttribute> element within the <Custom> element.
Custom attribute values provide metadata, but are not referenced when you create the routing assembly from the P&ID file.

For example, to define a custom attribute width with the value 1.345 for a pipe segment, include the following in the <PipeSegment> element: <Custom> <CustomAttribute name="width" value="1.345"/> </Custom>.
<CustomAttribute> name Defines a string for the name of the custom attribute.
value Defines a string value for the custom attribute.
