Partition Rollback and API Handles
Partition rollback, introduced in SolidWorks 2003, has changed the way
that SolidWorks caches bodies.
Before partition rollback: |
The FeatureManager design tree and bodies were cached. Cached bodies
remained valid even if a model was rolled back to a state where one or
more bodies had not yet been created, because the SolidWorks API was able
to get hold of the cached bodies. |
With the introduction of partition rollback: |
Bodies are no longer cached. Thus, the SolidWorks API handle is not
valid after a model is rolled back to a state where one or more bodies
have not yet been created. |
