Reducing Regeneration Time
When you regenerate a part after modifying it, the system recalculates the geometry of the part. For example, changing dimensional values, editing relations, or altering dimension tables require part regeneration.
The system performs a fast regeneration by regenerating only the features affected by certain actions. Fast regeneration is performed in the following situations:
Modifying dimension values—The part regenerates from the earliest modified feature only.
Resuming features—The part regenerates from the earliest resumed feature.
Redefining features, and modifying schemes and patterns—The part regenerates from the earliest modified feature only.
The entire part is regenerated when you modify the following:
Part accuracy
Part unit value
You can significantly enhance regeneration time by doing the following:
Create identical or varying patterns instead of general patterns.
Suppress features that have not been modified since the last regeneration.
