XFM Feature Propagation Rules
Since a feature can be comprised of one or more component features, XFM uses propagation rules to control how all the pieces are handled during element manipulation. Propagation flags are defined for every XFM sub-feature. The propagation flags can be set to Never, Always, or Lock. If the flag is set to Lock, then the change is propagated only if the MicroStation Graphic Group lock is on. If the flag is set to Always, then the change is always propagated.
