Creating an External Parameter  

This tasks shows how to create an external parameter.
  • Make sure you have selected:
    • The Parameters and the External References check boxes below the Display in Specification tree settings in the Tools>Options>Infrastructure> Part Infrastructure>Display  dialog box,
    • The With Formula and With Value check boxes below the Parameter Tree View settings in the  Tools>Options>General>Parameters and Measure > Knowledge tab.
    • Keep link with selected object check box (Tools>Options>Infrastructure>Part Infrastructure>General.)
  •  Open the DeactivatingExternalParameter.CATProduct file.
  • Note that the external parameters created at a product level are not fully integrated to the update process. Synchronize the external parameters manually before updating your document.  

  1. Expand the Part1_External_Parameter(Part1.1)\Part1_External_Parameter document, right-click the Integer.1 and Integer.2 parameters located below the Parameters node in the specification tree, and select the Copy command.

  2. Double-click, then right-click Part2_External_Parameter (Part2.1)\Part2_External_Parameter and select the Paste Special command. In the Paste Special dialog box, select As Result With Link and click OK to validate. The External Parameters node is added to the specification tree and the Integer.1 and Integer.2 parameters are displayed.
  The screenshot here above shows that when a parameter is imported, a local parameter similar to the pointed parameter is created (Integer.1 and Integer.2). A link towards the pointed parameter is also automatically generated.

In case, if the publication is redirected towards another parameter of different type, the pointed parameter changes its value and the corresponding local parameter displays an error - The pointed parameter must be of the same type as the external parameter.
