[ARX] SOS求助：尺寸标注方面问题！！！！！！！

我是一个ARX二次开发CAD的新手，做了一个尺寸自动标注的程序，部分代码如下：
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->setDimgap(0.5);    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.ZB_X+t,KD.ZB_Y+t,0);    AcGePoint3d Pt2(DY.m_Chang+t,KD.ZB_Y+t,0);    AcGePoint3d Pt3(KD.ZB_X+t,DY.m_Kuan+t+150+k*70,0);    AcGePoint3d Pt6(KD.ZB_X+t-KD.KongJing/2*cos(PI/4.0),KD.ZB_Y+t+KD.KongJing/2*sin(PI/4.0),0);    AcGePoint3d Pt7(KD.ZB_X+t+KD.KongJing/2*cos(PI/4.0),KD.ZB_Y+t-KD.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();    AcDbAlignedDimension *pDim1 = new AcDbAlignedDimension(Pt1, Pt2,Pt3,NULL,dimrecordid);    AcDbDiametricDimension *pDim3 = new AcDbDiametricDimension(Pt6, Pt7,leaderLength,dimText,dimrecordid);    pDim3->setLeaderLength(20);    AcDbObjectId Id;    pBlockTableRecord->appendAcDbEntity(Id, pDim1);    pBlockTableRecord->appendAcDbEntity(Id, pDim3);    pBlockTableRecord->close();    pDim1->close();    pDim3->close();
现在我希望标出的值是图形实际尺寸的一半，而不是尺寸的实际值，不知道对程序怎样操作。恳请高手不吝赐教，再次表示感谢，鲜花赠上

AcDbRotatedDimension *pdim;pdim->setDimlfac(0.5)就可以了
