I am inserting objects from one C4D file into another using MergeDocument().

If I want to add undo for that, how do I use the AddUndo()?
Do I have to put a UNDO_NEW for each object inserted? Or do I have to put a UNDO_CHANGE before the MergeDocument command? In the latter case, what pointer do I need to pass in the AddUndo(type,pointer) command?

Thanks for help.

As an addition: This is what I try to do:

  
doc->StartUndo();   
if (!MergeDocument(doc,bodyFile,SCENEFILTER_MATERIALS|SCENEFILTER_OBJECTS,NULL))   
{   
GePrint(GeLoadString(IDS_s**cE_ERROR_BODYOBJECT));   
bodyOp = BaseObject::Alloc(Onull);   
doc->InsertObject(bodyOp,NULL,NULL);   
doc->AddUndo(UNDO_NEW, bodyOp);    //add an undo for the insertion   
}   
else   
{   
doc->AddUndo(????);    //add an undo for the MergeDocument ?   
}

MergeDocument() automatically creates an undo step. If want to have more control you have to use LoadDocument() and merge the objects manually.
