    The External parameter selection dialog box is displayed.
  5. In the External parameter selection dialog box, select the one of the features in the external parameters list and click OK.
    The parameter definition is carried forward to the formula editor.
  6. Complete the formula definition.
  7. Click OK in the Formulas editor.
    You are back to the Formulas dialog box. From the parameter list, the parameter value is modified according to the formula specified. The External Parameters node is added to the tree.
  8. Click OK to add the formula to the document and exit the dialog box.
  9. From the Tools section, click Links & Relations .
    The displayed dialog box confirms that there is a link between the objects in both documents.
