If some drawings or other file documents become unnecessary, you can delete them from Document manager.
Note: In some configurations, deleting drawings or other file documents from Document manager is not allowed.
Tip: If you have deleted some GA drawings, and you want to have the GA drawings renumbered, in modeling mode, enter Renumber all GA drawings in Quick Launch and press Enter. This command renumbers all GA drawings starting from number 1 in the order that they were originally created. Use this command in single-user mode only.
