Create an anonymous group

By Virupaksha Aithal

Anonymous groups can be created using the function “SetAt”, on the group dictionary. Please refer to the sample code shown below

[CommandMethod("creatAnonymGroup")]
public void creatAnonymGroup()
{
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Editor ed = doc.Editor;
    Database db = doc.Database;
 
    PromptSelectionResult result = ed.GetSelection();
    if (result.Status != PromptStatus.OK)
        return;
 
    using (Transaction Tx =
        db.TransactionManager.StartTransaction())
    {
 
        DBDictionary groupDic =
            (DBDictionary)Tx.GetObject(db.GroupDictionaryId,
                                              OpenMode.ForWrite);
        Group anonyGroup = new Group();
        groupDic.SetAt("*", anonyGroup);
 
        foreach (SelectedObject acSSObj in result.Value)
        {
            anonyGroup.Append(acSSObj.ObjectId);
        }
        //groupDic
        Tx.AddNewlyCreatedDBObject(anonyGroup, true);
 
        Tx.Commit();
    }
}
