Resynchronizing DGN File Levels with Library Levels
While a level library is attached to the open DGN file, when you place an element while the Active Level is set to a library level, the level definition is copied from the library to the open DGN file. Because the copy can be modified independently of the original, the levels can become unsynchronized. Should this happen, you may at some point decide to resynchronize them.
Administrators can limit the effects of synchronization to particular level properties by setting the configuration variable MS_LEVEL_EDIT_ATTRIBUTE_LIST .
