Update Items and BOMs in Vault automatically when you make changes to your file data from AutoCAD Mechanical.
Synchronize Changes to Title Blocks in AutoCAD Mechanical with Vault
If you make changes to a title block in AutoCAD Mechanical, check the file back in to synchronize the changes with Vault.
Tip: Be sure to select the Keep File Checked Out check box if you plan to continue working on the file.
In addition, entering data directly into your AutoCAD Mechanical BOM and checking the file back in will also synchronize changes with Vault.
