You can import a Piping and Instrumentation Diagram (P&ID) file created with an external system and use that file as a guide in building route assemblies.
To import route specifications from a P&ID file, click
Piping and Instrumentation 
from the SolidWorks Task Pane, select the P&ID file, and click
Import P&ID.
You must import the P&ID data file in
.xml format. For an example, see
Documents and Settings\All Users\Application Data\SolidWorks\SolidWorks_Version\design library\routing\piping\pnid sample.xml. The path to the Application Data folder depends on your operating system. You must show hidden files to view this folder.
As a best practice, import schematics from a P&ID file to design a piping route:
- The piping design matches the connectivity and pipe sizes in the schematic.
- Design validation tools warn of any deviation from the schematic.
