尺寸标注问题！！！！！！！！！！！！

lwh-1234

在这个高手如云的地方，再次希望有人帮我解决一下下面的这个小问题！

我做了一个自动标注孔尺寸（包括孔径、孔深）的程序，部分代码如下：

 double leaderLength=50;
   int iDimColor=1;
   int iTextColor=1;
   AcCmColor color; 
   char* dimText=="光孔<>";
   AcDbDatabase *pcurdb=acdbHostApplicationServices()->workingDatabase();
   AcDbDimStyleTable *pnewdimtable;
   pcurdb->getSymbolTable(pnewdimtable,AcDb::kForWrite);
   AcDbDimStyleTableRecord *pnewdimrecord=new AcDbDimStyleTableRecord();
   pnewdimrecord->setDimasz(20);//设置箭头大小
   pnewdimrecord->setDimzin(8);//十进制小数显示时，抑制后续零
   pnewdimrecord->setDimexe(30);//设置尺寸界线超出尺寸线距离为400
   pnewdimrecord->setDimexo(0);//设置尺寸界线的起点偏移量为300
   pnewdimrecord->setDimtxt(30);//设置文字高度
   pnewdimrecord->setDimtad(1);//设置文字位置-垂直为上方，水平默认为居中，不用设置
   pnewdimrecord->setDimgap(10);//设置文字位置-从尺寸线的偏移量
   pnewdimrecord->setDimtih(0); 
   pnewdimrecord->setDimtix(1);//设置标注文字始终绘制在尺寸界线之间
   pnewdimrecord->setDimtofl(1);//即使箭头放置于测量点之外，尺寸线也将绘制在测量点之间
   pnewdimrecord->setDimlfac(0.125);
   color.setColorIndex(iDimColor);
   pnewdimrecord->setDimclrd(color);        //尺寸线颜色
   pnewdimrecord->setDimclre(color);        //尺寸边界线颜色
   color.setColorIndex(iTextColor);        
   pnewdimrecord->setDimclrt(color);        //文字颜色

   AcDbObjectId dimrecordid;
   pnewdimtable->add(dimrecordid,pnewdimrecord);
   pnewdimtable->close();
   pnewdimrecord->close();
 
   AcGePoint3d Pt1(KD[k].ZB_X+t-KD[k].KongJing/2*cos(PI/4.0),KD[k].ZB_Y+t+KD[k].KongJing/2*sin(PI/4.0),0);
   AcGePoint3d Pt2(KD[k].ZB_X+t+KD[k].KongJing/2*cos(PI/4.0),KD[k].ZB_Y+t-KD[k].KongJing/2*sin(PI/4.0),0);
    
   AcDbBlockTable *pBlockTable;//定义块表指针
   acdbHostApplicationServices()->workingDatabase()
   ->getSymbolTable(pBlockTable, AcDb::kForRead);
   AcDbBlockTableRecord *pBlockTableRecord;
   pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,
   AcDb::kForWrite);
   pBlockTable->close();
   AcDbDiametricDimension *pDim = new AcDbDiametricDimension(Pt6,Pt7,leaderLength,dimText,dimrecordid);
   pDim->setLeaderLength(20);
   AcDbObjectId Id;
   pBlockTableRecord->appendAcDbEntity(Id, pDim);
   pBlockTableRecord->close();
   pDim->close();
  }

运行后标出了孔的直径，形式为“光孔Ф120”。其中“Ф120”是系统自动读取生成的。现在我想把Ф换成M，也就是变成“光孔M120”，不知道可不可能，怎末才能实现，请指教，谢谢1
