[ARX] SOS求助：尺寸标注方面问题！！！！！！！

lwh-1234

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[k].ZB_X+t,KD[k].ZB_Y+t,0);
   AcGePoint3d Pt2(DY.m_Chang+t,KD[k].ZB_Y+t,0);
   AcGePoint3d Pt3(KD[k].ZB_X+t,DY.m_Kuan+t+150+k*70,0);
   AcGePoint3d Pt6(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 Pt7(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();
   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

谢谢wuddy的热心指教，问题解决了。

再次表示感谢！！
