About Backing Up the Model and References
Working with the Backup Model
For both diagnosing and fixing a problem in Resolve Mode, you can choose to work on the failed model or a backup model. The backup model shows all features in their pre-regenerated state, and can be used to modify or restore dimensions of the features that are not displayed in the failed model.
If Preferences > Create Backup Models is selected from the Regeneration Manager, the regenerated backup model is used. A copy of the model is saved as regen_backup_model####.prt prior to each regeneration. After successful regeneration of the feature, the copy is removed.
If Preferences > Create Backup Models is not selected, then the last saved pre-failure version of the current model is used.
When you open a backup model that has already been saved and that contains failed features in Resolve mode, you are prompted to click Continue to open the backup model, or Change to open a different backup model.
Creating Backup References
Backup references are used to prevent feature failure when a reference model is not in session. When a backup reference is available you can highlight and dynamically preview a reference when the original is not present.
Some reference types, such as Direction References and Chains, are automatically backed up. You can create additional backup references from
File >
Options. Click
Assembly and set the options under
External Reference Control.
When the original reference is missing and a feature uses a backup reference:
• The feature is regenerated with the backup references when possible and the backup reference is shown in the collector and can be highlighted.
• Reference status is displayed in the collector and in the Troubleshooter dialog box.
• Preview is available. You can choose to make changes and complete the feature using the backup reference or to cancel the tool.
When the original reference is missing and the feature has no backup reference:
• The feature fails.
• A missing reference is marked in the collector.
• No preview is available.
• You cannot resolve the failure until the reference is replaced, the original is found, or the feature is suppressed or deleted. Canceling the tool will not resolve the failure.
When the original reference has become invalid and the feature has no backup reference:
• The feature fails.
• The failed or invalid reference is marked in the collector.
• No preview is available.
• You cannot resolve the failure until the reference is replaced, or the feature is suppressed or deleted. Canceling the tool does not resolve the failure.
