The retrieval process in Smart 3D supports restore. For example, when another application has been restored to a previous state, the Smart 3D design basis objects are deleted and re-created upon retrieve. To avoid duplicating 3D objects, the retrieval process checks systems, pipelines, and projects/contracts to see if they already exist with the same name and type as design basis objects. If so, the software correlates to the objects upon retrieve rather than creating new objects.
After the retrieve operation, you must re-correlate the other 3D objects (besides systems, pipelines, and projects/contracts) with the new design basis objects.
