You use the End Preparation Compatibility Rule node in the Catalog tree view to define the rules of compatibility for the end preparation of two mating ends.
EndPrep1
Specify the first end preparation code for which you want to define a mating port. Valid end preparation codes are listed in the End Preparation select list.
EndPrep2
Specify the second end preparation code for which you want to define a mating port. Valid end preparation codes are listed in the End Preparation select list.
The End Preparation Compatibility Rule node in the Catalog task defines the same rules as does the Mating Ports sheet in the workbook. See the Piping Reference Data.
