DatabaseRestoreForwardingXrefSymbols Method

RestoreForwardingXrefSymbols() redoes all the changes back to a proper external reference resolve status. If the original symbols are restored and then changes are made to the symbols before RestoreForwardingXrefSymbols(), those changes will be overwritten. However, newly added symbols are properly resolved during RestoreForwardingXrefSymbols(), and then are included in the undo/redo of future calls to these two methods. (The only workaround for wanting to change the symbols themselves is to go ahead and make the changes, save them to disk, and then let RestoreForwardingXrefSymbols() overwrite the changes. When all is done, reload the external reference from disk.) The symbols affected are the table and records for blocks, layers, linetypes, text styles, dimension styles, registered applications, and plot styles, as well as any custom object changes made during and between the XrefBeginAttached and XrefBeginOtherAttached events. To properly resolve the external reference, RestoreForwardingXrefSymbols() needs write access to the symbol tables and symbol table records in the host drawing. Therefore, applications should close any open symbol tables or symbol table records before calling RestoreForwardingXrefSymbols().
