From here you can create new piping elements and edit and delete the existing piping definitions. Hold mouse over piping definition name to get piping definition details.
When renaming an existing piping definition, the existing occurrences used in the survey texts will not be updated with the new name. This must be done manually.
When deleting a piping element, the existing tag occurrences will not be removed from texts. This must be done manually.
To create a new piping definition, click on the "New piping" link in the Menu box. When you create a new piping or edit an existing one, the first thing to do is to determine where the piping value will come from. This is called the piping source.
