The new parts are derived; they contain a reference to the parent part. Each new part contains a single feature named Stock- <parent part name> - n ->. You can reattach a derived part to a specified stock part, split feature, or body.
If you change the geometry of the original part, the new parts also change. If you change the split feature geometry, no new derived parts are created. The software updates the existing derived parts, preserving parent-child relations.
With multibody parts, the various split parts are listed in the FeatureManager design tree under Solid Bodies.
The original part contains all its original features plus a new feature called Split.
If you selected Consume cut bodies under Resulting Bodies, the solid body displayed in the graphics area is the original solid body minus the new parts. If all bodies in the original part were saved as split bodies, no solid body is displayed. To see the original solid body, move the rollback bar in the FeatureManager design tree above the split feature or suppress the split feature.
If you delete the split feature in the original part, the new parts still exist, but the status of the external reference in the new parts is dangling.
