Use the File Save Options dialog to specify the maximum number of backup files and other settings related to file saving.
To open the File Save Options dialog, use Save As from the application menu, and click Options in the Save As dialog.
- Maximum backups. Specifies the maximum number of backup files.
By default, non-workshared projects have 3 backups, and workshared projects have up to 20 backups.
- Make this a Central Model after save. Sets the current workset-enabled file to be the central model.
- Compact File. Reduces file sizes when saving workset-enabled files. During a normal save, Revit only writes new and changed elements to the existing files. This can cause files to become large, but it increases the speed of the save operation. The compacting process rewrites the entire file and removes obsolete parts to save space. Because it takes more time than a normal save, use the compact option when the workflow can be interrupted.
- Open workset default. Sets the workset default for the central model when opened locally. From this list, you save a worksharing file to always default to one of the following options: All, Editable, Last Viewed, or Specify. The only way a user can change this option is to resave a new central model by selecting "Make this a Central Model after save" on the File Save Options dialog. The local model can use the Reload Latest tool to update the changed option.
To change this setting in an existing central model, resave the file using Save As and adjust the Save Options.
When opened locally, you can override this default setting each time the project is opened. The override only affects that work session, and will revert to defaults the next time the file is opened.
- Preview. Specifies the preview image that displays when you open or save a project. The default value for this option is Active View/Sheet. Revit can create a preview image only from open views. If you select Regenerate if View/Sheet is not up-to-date, Revit updates the preview image whenever you open or save the project. This option can consume considerable resources on a complex model. Use it only if you want the preview image to update frequently.
