The Permissible Taps node (the PermissibleTaps sheet in the Piping Specification.xls workbook) defines the preferred tap and a list of permissible taps for a piping materials class. This rule is intended to be used for taps that are created by the piping designer versus taps that are created in the piping catalog. That is to say, when a piping designer goes to place a tap, the software checks this rule to get all the taps that are allowed for the active piping materials class. The software then goes to the Tap Property Data node (Tap Properties sheet) to retrieve the tap information to display to the piping designer.
Permissible Tap Number (Required)
Enter the tap number that you want to allow in the piping materials class. The tap number must be defined in Tap Properties.
Is Preferred Tap (Required)
Enter TRUE if the tap number is the preferred tap. Enter FALSE if the tap is not the preferred tap. You can have only one tap set to TRUE per specification name. If you do define more than one tap as true, the first tap in that specification is used and the other tap is treated as being set to false.
Spec Name (Required)
Type the name of the piping materials class for which you are defining the preferred and permissible taps. The piping materials class that you enter must be defined on the Piping Materials Classes.
