About Regeneration Failures
When a model is regenerated, the model is recreated feature by feature, in the order in which each feature was created, and according to the hierarchy of the parent-child relationship between features. Regeneration can fail for reasons such as the following:
Bad geometry
Broken parent-child relationships
Missing or invalid references
Missing components of an assembly
When regeneration fails, one of the following failure modes is activated:
Resolve mode (also referred to as Fix Model mode)
No Resolve mode
Set the regen_failure_handling configuration option to specify a failure mode. No Resolve mode is the default.
Change the failure mode temporarily for the current session by clicking Model > Regenerate > Regeneration Manager > Preferences > Failure Handling and selecting a mode.
