Topic: AU 2005 code - Part 9 "Gettin' Jiggy With It"

Hello,
your code helped me a lot. But now i have the problem that i use AutoCAD 2007 and there the following code does not work.
What do i have to do now?

Code: [Select]

IdMapping idMap = currentDb.DeepCloneObjects(entityCollection, currentDb.CurrentSpaceId, false);I get this error: Error   1   No overload for method 'DeepCloneObjects' takes '3' arguments

I need 4 arguments, but i do not know which IdMapping i have to use.

Welcome to TheSwamp Roland;

I think this is a way to do it:

Code: [Select]

        [CommandMethod("DeepClone")]
        public void deepclone()
        {
            Document doc = acadApp.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            IdMapping mapping = new IdMapping();
            ObjectIdCollection identifiers = new ObjectIdCollection();
            db.DeepCloneObjects(identifiers, db.CurrentSpaceId, mapping, true);
            foreach (ObjectId id in identifiers)
            {
                //...
            }
        }

Ignore my previous post, it was the first tryout, see if this one helps you, I used a selection set, but it will be easier to adapt it for your needs.

Code: [Select]

        [CommandMethod("DeepClone")]
        public void deepclone()
        {
        Document doc = acadApp.DocumentManager.MdiActiveDocument;
        Editor ed = doc.Editor;
        Database db = doc.Database;
        IdMapping mapping = new IdMapping();
        ObjectIdCollection identifiers = new ObjectIdCollection();

        PromptSelectionOptions prOpts = new PromptSelectionOptions();
        prOpts.MessageForAdding = "\nSelect objects: ";
        PromptSelectionResult res = ed.GetSelection(prOpts);
        if (res.Status != PromptStatus.OK) return;

        ObjectId[] ids = res.Value.GetObjectIds();
        foreach (ObjectId id in ids)
            identifiers.Add(id);

        db.DeepCloneObjects(identifiers, db.CurrentSpaceId, mapping, false);
        using (Transaction tr = db.TransactionManager.StartTransaction())
        {
            foreach (IdPair id in mapping)
            {
                DBObject obj = (DBObject)tr.GetObject(id.Value, OpenMode.ForWrite, false);
                Entity ent = obj as Entity;
            }
            tr.Commit();
        }
        }

Now i changed the code that it works for my use. The only problem is that it does not work with blocks. Now i changed the TransformSelectionSet to TransformSelectionSet2. There i use DeepCloneObjects and all works good. But if i want to transform blocks i get an error. Every other object works correctly. What do i have to do that i can transform a block?
