Deactivating External Parameters

You can deactivate external parameters meaning that when the external reference is isolated, it cannot be re-connected to the original parameter, it cannot be synchronized with the pointed value, but it keeps its last value (the value cannot be changed any longer).

This task shows you how to:

Before you begin: Make sure you have selected:
  • The Parameters and the External References check boxes in Me > Preferences > 3DEXPERIENCE Platform Common Preferences > Display > 3D Shape Infrastructure.
  • The With Formula and With Value check boxes in Me > Preferences > 3D Modeling > Multi Discipline Automated Engineering > Knowledge Basics > Parameters & Relations > Parameters tree view.
  • Keep link with selected object check box (Me > Preferences > 3DEXPERIENCE Platform Common Preferences > General.

Creating an External Parameter

Create the External Parameter

You must first create the external parameter.

Before you begin: Create a product containing two other products. The first product must contain a line and a Line_Length parameter that computes the line length.
  1. Expand the first representation, right-click the Line_Length parameter located below the Parameters node in the tree, and select the Copy.
  2. Double-click, then right-click the second representation, and select Paste Special.
  3. In the Paste Special dialog box, select As Result With Link and click OK to validate.
    The External Parameters node is added to the tree and the copied parameter is displayed.

Isolate the External Parameter

You can isolate the external parameter.

  1. Click Line_Length under the External Parameters node and select Links & Relations from the Standard section of the action bar.

    If Links & Relations is not available, make sure you are in the Engineering Rules Capture app.

  2. Select the link in the window, click Isolate link and click OK.
    A new Parameters node is created containing the isolated parameter and the External parameters node is now empty.
    Note: An isolated external parameter loses the ability to be synchronized and keeps its last value.
If the external parameter is not created, make sure it was properly created using the Formula editor.
