You can save selected attribute values or all compared attribute values of a comparison network to new, user-defined attributes. Thus, the values are kept after termination of the version comparison.
You proceed differently depending on the version comparison chosen.
Creating user-defined attributes by adopting direct attributes during version comparison
1. From the File menu, choose Compare and transfer networks > Version comparisons.
The Version comparisons window opens.
2. Select the desired version comparison or the desired attributes.
3. Click the 
Copy to user-defined attributes button.
The version comparisons or attributes are saved to new user-defined attributes.
|
Note: Since user-defined attributes do not have subattributes, a user-defined attribute is created for each subattribute. ID and short name of the new user-defined attributes are generated from the original short name of the attribute, added by the name of the version comparison. If the generated ID already exists, an error message is displayed and this attribute will not be created. |

If the generated ID already exists, an error message is displayed and this attribute will not be created. |
