When you modify features in a complex part or assembly, it may be convenient to postpone regeneration until you make all your changes, since regeneration can be time consuming. (For more information, see “Editing a feature,” Section 42.4.1.) When you are ready to regenerate the part or assembly, you can select Feature
Regenerate from the main menu bar. You can also regenerate a feature by clicking mouse button 3 on the feature in the Model Tree and selecting Regenerate from the menu that appears.
To regenerate a part or assembly:
From the main menu bar, select FeatureRegenerate.
Tip:
You can also regenerate a feature using the 
tool located in the module toolbox.
ABAQUS/CAE regenerates the part or assembly.
If regeneration fails, a dialog box appears. In this case you can choose one of the following options:
Click Undo Changes to return to the original part or assembly and discard all your changes.
Click Keep Changes to continue the regeneration, suppressing those features that failed to regenerate.
Note: Features that are suppressed as a result of the failure are resumed automatically if you correct the cause of the failure.
