C# SendKeyin 调用VBA，结果不完全

参考了这个教程“Create Drawing”对话框设置 - 技术资料库 - Bentley 中国优先社区 - Bentley Communities

想不打开 Create Drawing 快速生成剖面图，录制的宏和VBA代码如下：

C#中用Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin调用keyin命令

public static MyModalDialogEvents Instance = new MyModalDialogEvents();
        void BIM.IModalDialogEvents.OnDialogOpened(string DialogBoxName, ref BIM.MsdDialogBoxResult DialogResult)
        {
            if (DialogBoxName == "Create Drawing")
            {
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_COINCIDENTSHEET_OFF");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_ASSIGNSAVEDVIEWNAME 圆形井剖面" );

                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_SET_DRAWINGBOUNDARY 1");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_COINCIDENTSHEET_OFF");

                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_SET_DISCIPLINE 建筑");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_SET_PURPOSE 剖面");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND DRAWCOMP_VISIBLEEDGES 1");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND DRAWCOMP_VISIBLEEDGES 1");

                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_ADDSHEETTOSHEETINDEX_OFF");
                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_COINCIDENTSHEET_OFF");

                Bentley.MstnPlatformNET.InteropServices.Utilities.ComApp.CadInputQueue.SendKeyin("MDL COMMAND CREATEDRAWING_OPENMODEL_ON");



                //DialogResult = BIM.MsdDialogBoxResult.OK;
            }
        }

其中MDL COMMAND CREATEDRAWING_SET_DRAWINGBOUNDARY 1，是选择drawing boundary的，默认情况是 new，想选择为第二个选项，如下图

执行代码后，发现对话框上的Name成功更改了，但是drawing boundary没有按照代码的设置，想问以下有什么办法能够将Drawing Boundary 或者其他的选项也通过代码设置成自己想要的内容呢？
