To Regenerate a Model
1. Click on the Quick Access toolbar. Alternatively, on the Model tab, click the arrow next to Regenerate and then click Regenerate.
2. Creo Parametric rebuilds your change in the part or assembly model.
3. If a feature fails regeneration, Creo Parametric enters the Resolve environment.
