You can assign a line number to group pipe segments and fittings in the 3D model.
Pipe segments and fittings are grouped based on a line number. You can assign a line number before routing pipe. You can use the line number to select pipe in the model. For more information, see Select Piping.
You can use the P&ID Line List to create pipe using a line number. The line number is assigned in the model if the line number tag formats are compatible. For more information, see About Pipe Line Numbers.
You can assign line numbers globally, by name, using the Data Manager to rename the line number.
When you create pipe that is assigned to a line number, you can set the layer name that the pipe is created on to include the line number in the name. For more information, see About Configuring Automated Layer and Color Assignments.
The default line number format includes only the line number property (for example: 101).
You can set the line number format in the P3d Line Group class. For more information, see About Tag Formats. If you set the line number format to Spec-Service-Line, you can assign the following line number: CS300-P-101.
Pipe lines in a P&ID drawing and a model are independent of each other and are not linked. You can check for property differences by validating matching line numbers, but the values are not linked. For more information, see About Validating Plant 3D Models.
In a P&ID drawing, the line number is a property of the line group. Any pipe line segment or component that belongs to the same line group has the same line number.
P&ID line groups are managed as a unit. You can add lines and components to the group (for example: using slgroupedit). When you change the line number of a group in a P&ID drawing, the line number changes for all lines and components in the group.
In a Plant 3D drawing, if you select a single piece of pipe and change its line number, connected pipe and fittings do not change. The Properties palette does not allow you to set a line number if selected items are not connected.
