本例为给标注加前缀，也可定制其他形式，效果如下：
public class Demo{[CommandMethod("xx")]//public void Dim(){Document doc = Application.DocumentManager.MdiActiveDocument;Database db = doc.Database;Editor ed = doc.Editor;try{using (Transaction tr = db.TransactionManager.StartTransaction()){BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);foreach (ObjectId dimId in btr){if (dimId.ObjectClass.Name.ToLower().Contains("dimension")){Dimension dim = (Dimension)tr.GetObject(dimId, OpenMode.ForWrite);string originalText = dim.DimensionText;string measureText = Math.Round( dim.Measurement,3).ToString();if (!string.IsNullOrEmpty(originalText)){dim.DimensionText = "dzb_"+ originalText ;}else{ dim.DimensionText = "dzb_" + measureText; }if (!string.IsNullOrEmpty(measureText)){ed.WriteMessage($"\n{measureText}\n");}}}tr.Commit();ed.WriteMessage("\n修改标注文本前缀成功。");}}catch (System.Exception ex){ed.WriteMessage("\n发生错误: " + ex.Message);}}}插件联系↓↓↓
