Label Format Validation

For certain label fields, the project may be set to check that entered labels correspond to a specified format, in other words, that they consist of the correct type of characters in the correct order.

For example, the equipment Prefix field may be set so that all entries in this field must begin with an uppercase letter, followed by a lower-case letter, then a number, and so on.

These settings are made using the AVEVA P&ID Project Administration program, using the Pipes - Validation Sub-Category, Instruments - Validation Sub-Category, Equipment - Validation Sub-Category, Valves - Validation Sub-Category, Nozzles - Validation Sub-Category and Miscellaneous - Validation Sub-Category

If an invalid entry is made in a Properties dialog an error message is displayed, and the invalid label may not be placed.
