Results of a Failed Regeneration
The geometry of a feature must be regenerated when the geometry of any of its parents, including topology parents, is changed. When there are no changes to the parents of a feature, its original geometry is preserved during the regeneration process to speed up regeneration time and to avoid triggering chain regeneration in Assembly mode.
When a model regeneration is completed with failures, one or more of the following types of items is created:
Item
Definition
Display
Geometry Status
Child of Failed feature
A feature with one or more local parents that are failed or child of failed features.
In the graphics window, surfaces of the feature are displayed in blue.
In the Model Tree, the feature name appears in red, and the glyph is not displayed.
May or may not have its preregeneration geometry restored. If it does, the geometry is not up-to-date.
Child of External Failed feature
A feature with one or more external parents that are failed or child of failed features.
In the graphics window, the geometry display does not change.
In the Model Tree, the feature name is red, and the glyph is not displayed.
Has geometry that may or may not be up-to-date.
Cannot be restructured.
Failed feature
A feature that fails for reasons other than failed parents.
In the graphics window, surfaces of the feature are red.
In the Model Tree, the feature name is in bold, red font. The feature is marked with the glyph.
May or may not have its preregeneration geometry restored. If it does, the geometry is not up-to-date.
Failed model
A model with one or more failed features.
In the graphics window, surfaces of failed features are red, and surfaces of child-of-failed features are blue.
Has geometry that is not up-to-date.
Out-of-date reference
A reference that belongs to a failed or child-of-failed feature.
In a reference collector, out-of-date references have a yellow prefix dot.
Since the geometry of a failed feature is nonexistent or not up to date, the regeneration of all its children, including topology children, is temporally suspended until the failure is resolved. As a result, the children have no geometry, or their original geometry is restored.
* 
The geometry status for a child of a Child of External Failed feature is Regenerated when the child has no other parents that are Failed or Child of Failed.
