[Group code] 1005 [Description] Handles of entities in the drawing database NOTE When a drawing with handles and extended data handles is imported into another drawing using INSERT, INSERT *, XREF Bind, XBIND, or partial OPEN, the extended data handles are translated in the same manner as their corresponding entity handles, thus maintaining their binding. This is also done in the EXPLODE block operation or for any other AutoCAD operation. When AUDIT detects an extended data handle that doesn't match the handle of an entity in the drawing file, it is considered an error. If AUDIT is fixing entities, it sets the handle to 0.
