Label Display Options

The text of labels may either be in the default font select for the project, or in the text style assigned to the label type. Text styles are defined in the Text Styles Configuration Category of the AVEVA P&ID Project Administration program, and assigned to label types using the Label Types Configuration Category.

In addition, the height, justification and rotation settings of the text of a label are project configuration options, also set using the Label Types Configuration Category.

These values can be overridden for individual labels using their Properties Dialogs.

Non-Standard (Single Property) Label Format

Although the format of a label is fixed by the project configuration, it is possible to specify which part of a label is actually displayed on a drawing. This is achieved by selecting single property label formatting while labelling a pipe. For example, it may be required to have displayed only the specification part or only the number part of a label. It is possible to combine both fixed and non-standard label format on the same pipe, if multiple labels are applied.

Note: Once a format has been chosen and the pipe label placed on the drawing, the format cannot be modified. The label must be deleted and reapplied.

Split Label Format

Split Label Formatting is the placing of some fields of a pipe label above the pipe and the remainder below the pipe. Split Label Formatting is controlled by three associated project configuration options.

The Split After Field field in the Pipes - Labels Sub-Category of the AVEVA P&ID Project Administration program is used to select which field in the pipe format to split on. The number entered here determines how many fields to count from the left of the pipe label before the split occurs.

Note: Do not confuse these numbers with the order numbers allocated to fields in the project configuration for pipe labels.

For example, if the entry is 3, the pipe label will display with the first three fields above the pipe, and the remaining fields below it.

When split label formatting is turned on, the Y offset above line and Y offset below line fields are responsible for setting the offset from the label point picked when placing the pipe label. If the point picked is directly on the pipe, the Y offset distances are equal and the text justification for the pipe label is set to MC (Middle Centre), the pipe label will appear.

Note: The pipe label justification is BC (Bottom Centre) by default in the project configuration file.

The colours, heights, styles, and other formatting attributes of the parts of split pipe labels are defined by setting the properties of the XPO (first part), XPB (second part), XBO (third part), and XBT (fourth part) label types in the Label Types Configuration Category.

Formatting changes made in the AVEVA P&ID Administration program are implemented on a drawing using the Update Split Pipe Label Formatting procedure. They will not be implemented automatically.

Note: Only split pipe labels that have been upgraded as described in Upgrade Split Pipe Label Types can be formatted and updated in this way.

It is possible to change the pipe label display from single label display to split pipe label display or vice versa.

Note: If the configuration changes from single pipe label display to split pipe label display, the split pipe label configuration options are applied using the insertion point and display attributes of the original single pipe label as a reference. It is therefore possible that when the original single pipe label is too far from the pipe, the second pipe label may overlap the pipe and a manual displacement of the split pipe label needs to take place.

Null Characters

The default null character (e.g. ?) can be selected for all or for specific pipe label fields, if pipe data is not yet available. The label will then appear with the null character as defined by the project configuration. This is the only application of this facility.

For example, if the null character were used for each digit of the area number, pipe label 2"-SW-2001-S1A-5L would appear as 2"-SW-??01-S1A-5L.
