[求助]使用CAD的API怎样填充一个圆？

怎样填充一个圆？使用下面代码先创建一个圆然后填充，为什么运行到fillHatch.EvaluateHatch(false); 行时出现错误：“eAmbiguousOutput”？各位高手帮忙解决一下，先谢谢了。
         try
         {
            Database db = HostApplicationServices.WorkingDatabase;// 获得当前工作空间的数据库
            using(Transaction trans = db.TransactionManager.StartTransaction())// begin the transaction
            {
                  BlockTable bt = trans.GetObject(db.BlockTableId, OpenMode.ForWrite) as BlockTable;//获得块表
                  BlockTableRecord btr = bt[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForWrite) as BlockTableRecord;//获得模型空间的块表记录
               &nbspoint3d Point = Point3d(10, 200, 200);
                  Circle pointCircle = new Circle(Point, Autodesk..Geometry.Vector3d.ZAxis, 10);
                  btr.AppendEntity(pointCircle);
                  trans.AddNewlyCreatedDBObject(pointCircle, true);

                  ObjectIdCollection circleIds = new ObjectIdCollection();
                  circleIds.Add(pointCircle.Id);
                  trans.Commit();
                  Hatch fillHatch = new Hatch();// 填充
                  fillHatch.SetDatabaseDefaults();
                  btr.AppendEntity(fillHatch);
                  trans.AddNewlyCreatedDBObject(fillHatch, true);

                  fillHatch.Associative = true;
                  fillHatch.AppendLoop(HatchLoopTypes.Default, circleIds);
                  fillHatch.EvaluateHatch(false);

            } // Using
         }// try
         catch (System.Exception e)
         {
            CadEditor.Show(e.Message);
         }

不好意思，代码修正一下，各位高手帮帮办忙，谢谢。

try

            {
                  BlockTable bt = trans.GetObject(db.BlockTableId, OpenMode.ForWrite) as BlockTable;//获得块表
                  BlockTableRecord btr = bt[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForWrite) as BlockTableRecord;//获得模型空间的块表记录

加上fillHatch.SetHatchPattern(HatchPatternType.PreDefined, "ANSI35");
