To identify components in your diagram, you can create intelligent tags. You can add data to components in your diagrams and generate lists of equipment, pipelines, valves, and instruments.

As you modify diagrams, you can easily generate new lists. Show me an example. PFDs show how industrial process equipment is interconnected by a system of pipelines. On the File menu, point to Newpoint to Engineeringand then click one of the following:. From Equipmentdrag equipment shapes onto the drawing page.

Drag a pipeline shape from Pipelines onto your drawing page, and then position one of its endpoints on an equipment shape. You can connect a pipeline to any point on the outside of an instrjment shape, even if the shape has no connection point there. The endpoint of the pipeline turns red to indicate that it is connected glued to the equipment shape, and a connection point instument created if one did not exist.

To change the appearance or show the flow direction of a pipeline, select the pipeline, and then select a style from the Line Style list on the toolbar. Styles control the thickness of the line, directional arrows, and other graphic symbols that indicate the type of pipe or instrument line.

You can also use the Connector tool to draw pipelines. This method is particularly useful when you work in large diagrams that have many connections. Click instru,ent Connector tool, and then on Pipelinesclick the pipeline shape you want to use. Then draw the instrment in your diagram. To change the type of pipeline, simply click a different pipeline shape on Pipelines and continue working in your diagram. From Valves and Fittingsdrag valve shapes on top of pipelines.


Release the mouse button when a red square appears, indicating that the valve is glued to the pipeline.

From Instrumentsdrag instrument shapes onto the drawing page near the pipeline, valve, or equipment they monitor. On the View menu, click Shape Data Window.

On the Tools menu, click Shape Data Sets. Choose whether to create a new shape data set, a set based on the currently selected shape, or a set based on an existing shape data set, and then click OK. To add or modify shape data, select the shape data set, and then click Define. On the Process Engineering menu, click Renumber Components. In the Renumber Components dialog box, under Apply tospecify whether to renumber the components in the entire document, on the current page, or in the current selection.

In the Include tag symbls list, click to clear the check boxes for the tag formats that you don’t want to include in the renumbering. Assign a starting value and an interval value for renumbering.

You can assign a different start value and interval value to each tag format. Click an item in the Include tag formats list to highlight it.

In the Starting value box, type or select the starting value for renumbering. In the Interval box, type or select the increment used to renumber the components. Generate lists or bills of materials of equipment, pipelines, valves, and instruments. Create a custom report definition or skip to step 3 to use an existing report definition.

Create a P&ID or PFD

The following steps create a report definition that filters out duplicate process engineering shapes and reports on process engineering components. Symbolls Limit Selection to define the criteria for the report. Click Add to put this condition in the defined criteria list, and then click OK.


In the Report Definition Wizardclick Next. Then select the check boxes for other data you want to report on, and then click Next. To filter out duplicate process engineering shapes and report on components, click Subtotals. In the Options dialog box, click Don’t repeat identical valuesand then click OK twice. In the Report Definition Wizardclick Nextenter the information to save your report, and then click Finish.

In the Report dialog box, you can either run the report or click OK to save your definition and run it later. To create a new report definition based on an existing one, in the Report dialog box, select the existing definition, and then click New. Save the modified report definition with a new name. In the Report Definition list, click the name of the report definition you want to use.

The report definition determines which shapes are reported on and which shape data are included in your report. Click Runand then in the Run Report dialog box, click the report format you want, and then do one of the following:.

If you are saving your report as a shape on the drawing, choose whether to save a copy of the report definition with the shape or link to a report definition. If you ran a custom report, when you return to the Report dialog box, click OK to save your definition.
