Unexpected Extents of Symbols

If in a DGN a cell is created with an attached library, it can be converted to a shared cell. The extents of shared cells may be affected by whether some tags in the library have been deleted. This might then impact the tag identification as the undeleted tags might lie outside the cell's extents. This can be fixed in MicroStation by converting the shared cell to a normal cell, which restores the tags in the library and updates the cell with the correct extents.
