Manage Modifications

Editing a component library with Vertex BD 2021 (27.0) or earlier generated a customer-specific copy of the system library folder to the custom/complibs folder. In the library browser, you distinguish such libraries from the following labels:
  • Customized - Standard library label. The customer-specific library folder contains individual drawing or model files or ADT programs that overwrite the corresponding standard library files. However, the library database is in the system library folder.
  • Overwrites - Custom library label. The customer-specific library folder contains both component drawing or model files or ADT programs and the library database that manages the library. The customer-specific library overwrites the system library.

To view modifications and compare customer-specific and system library differences, follow these steps:

  1. Open the library browser by selecting System | Libraries | Libraries.
  2. Select a library with the label [Customized] or [Overwrites].
    • [Customized] - Standard library
    • [Overwrites]- Custom library

    For example, first select All Libraries, and then sort the libraries by Note column.

  3. Right-click to open the context-sensitive menu.
  4. Select Manage Modifications. The Manage Modifications dialog box opens.

Dialog Box Options

Use Customization
Customer-specific changes are applied when Use Customization is selected.
To disable customer-specific changes and re-enable the system library, clear the check box. In Windows Explorer, the customer-specific library folder is moved to the complibs_obsolete folder, and the system library folder is enabled. The library gets the label Restored in the browser.
To re-apply your customer-specific changes, select Use Customization.
Comparison Method
The comparison method is "Custom library overwrites system library" in the case of custom library that [Overwrites].
The comparison method is “Custom files overwrite system files” in the case of [Customized] system library.
If it is a project-specific library and also a custom library that [Overwrites] exists, you can choose which comparison method to use:
  • Custom library overwrites system library
  • Project library overwrites system library
  • Project library overwrites custom library
Check item register modifications
Compare the differences between the database in the customer-specific library folder and the database in the system library folder. The function opens the Show Changes dialog box. Choose what you want to compare:
  • Compare structure - Compare the database fields. Choose from the options:
    • Compare types and lengths of the fields
    • Compare order of the fields
  • Compare contents - Select the Relation field, for example the row number $RID, and click Compare. View deleted, added, and changed content marked in different colors in the dialog box. If there are no markings, there are no differences in the databases.
Delete customized item register
Delete the database in the customer-specific library folder. The program will prompt you for confirmation before deleting the database:
“System library may be corrupt if current library ui has not been used for previous modifications. Remove customized item register permanently?"
If you are not sure, select No and try disabling customer-specific changes first by clearing the Use Customization check box. Exit reviewing modifications and test the library. If you then want to delete the customer-specific database, reselect the function Manage Modifications, select Use Customization, click Delete customized item register and click Yes.
File / Status
The list shows the files in the customer-specific library folder and their status:
  • Copy - The file is the same as in the system library folder.
  • Local - The file does not exist in the system library folder at all.
  • Overwrites - The file is different from the system library folder. In the case of a drawing file (*.vxp), you can compare the changes by selecting Compare changes from the right-click menu. More information on the corresponding function: Show Differences of Drawings.
To delete a file, select Delete file from the right-click menu.
