The Default Change of Direction Rule node (the DefaultChangeOfDirection sheet in the Piping Specification.xls workbook) defines the default boundaries for change-of-direction fittings during automatic placement. This rule contains all the default values that the software is to use in the piping specification. You can define exceptions for a particular piping materials class in the Default Change of Direction Per Spec.
Bend Angle From (Required)
Specifies the lower boundary for the bend angle. This value must match the Bend Angle To value on the previous row.
Bend Angle To (Required)
Specifies the upper boundary for the bend angle. This value must match the Bend Angle From value for the next row.
Functional Short Code (Required)
Specifies the functional short code to use to access the piping commodity filter for the change-of- direction fitting.
Functional short codes for change-of-direction fittings are defined here, not on the Piping Commodity Filter.
