为什么注记文字加不上？这段代码不对吗？

        private void MakeAcDbText(AttributeReference obj, BlockReference objBLK)<br/>        {<br/>            Autodesk.AutoCAD.DatabaseServices.Database db = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database;<br/>            Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = db.TransactionManager;<br/>            Autodesk.AutoCAD.DatabaseServices.Transaction ta = tm.StartTransaction();<br/>            try<br/>            {<br/>                BlockTable bt = (BlockTable)tm.GetObject(db.BlockTableId, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForRead, false);<br/>                BlockTableRecord btr = (BlockTableRecord)tm.GetObject(bt, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForWrite, false);<br/>                Autodesk.AutoCAD.DatabaseServices.DBText newText = new DBText();<br/>                newText.TextString = obj.TextString;<br/>                newText.TextStyle = obj.TextStyle;<br/>                newText.Position = obj.Position;<br/>                btr.AppendEntity((Entity)newText);<br/>                tm.AddNewlyCreatedDBObject((Entity)newText, true);<br/>                ta.Commit();<br/>            }<br/>            catch<br/>            {<br/>                FileStream fs = new FileStream("提示.txt", FileMode.Append);<br/>                StreamWriter sw = new StreamWriter(fs);<br/>                sw.WriteLine(objBLK.BlockName.ToString());<br/>                sw.WriteLine(objBLK.Name.ToString());<br/>                sw.WriteLine(objBLK.Layer.ToString());<br/>                sw.Close();<br/>                fs.Close();<br/>            }<br/>            finally<br/>            {<br/>                ta.Dispose();<br/>            }<br/>        }<br/><br/>

自动桌子的代码，有看http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%20.NET%20Developer's%20Guide/index.html
么？
同一内容最好不要重开贴：）
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Geometry;


public static void CreateText()
{
// Get the current document and database
Document acDoc = Application.DocumentManager.MdiActiveDocument;
Database acCurDb = acDoc.Database;

// Start a transaction
using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
{
      // Open the Block table for read
      BlockTable acBlkTbl;
      acBlkTbl = acTrans.GetObject(acCurDb.BlockTableId,
                                 OpenMode.ForRead) as BlockTable;

      // Open the Block table record Model space for write
      BlockTableRecord acBlkTblRec;
      acBlkTblRec = acTrans.GetObject(acBlkTbl,
                                    OpenMode.ForWrite) as BlockTableRecord;

      // Create a single-line text object
      DBText acText = new DBText();
      acText.SetDatabaseDefaults();
      acText.Position = new Point3d(2, 2, 0);
      acText.Height = 0.5;
      acText.TextString = "Hello, World.";

      acBlkTblRec.AppendEntity(acText);
      acTrans.AddNewlyCreatedDBObject(acText, true);

      // Save the changes and dispose of the transaction
      acTrans.Commit();
}
}

搞定，不过一些细节还没弄清楚，比如对齐方式、什么时候要给AlignmentPoint等等，还是谢谢几位

<p>默认的左对齐设置Postion</p><p>其余的设置AlignmentPoint</p><p>具体的要仔细调试下</p><p>AlignmentPoint通常在设置对齐方式后设置</p>
