[求助]：怎样用修改的尺寸标注样式啊，求救

ltaotie

一个修改尺寸标注的子程序，主要就是想修改全局变量，因为发现画出的图形相对尺寸太小。但是运行后发现尺寸还是那样，看AutoCAD中标注－样式的全局变量还是1（我的AutoCAD2002中默认标注样式为ISO-25）。到底改该怎样做啊
editdimStyle()
{
        AcDbDimStyleTable *pDimStyleTbl;
        acdbCurDwg()->getDimStyleTable(pDimStyleTbl,AcDb::kForRead);
        AcDbDimStyleTableRecord *pDimStyleTblRcd;
        if(Acad::eOk==pDimStyleTbl->getAt("ISO-25",pDimStyleTblRcd,AcDb::kForWrite))
        {
                pDimStyleTblRcd->setDimscale(0.1);
                pDimStyleTblRcd->close();
        }
        pDimStyleTbl->close();
}

Acad::ErrorStatus setDimstyle(AcDbObjectId styleId);

具体要怎样啊？假如画了一直线并标注了尺寸，,程序都是照着书上套的.：
AcGePoint3d pt1(pt1x,pt1y,0),pt2(pt2x,pt2y,0);
AcDbLine* pLine1=new AcDbLine(pt1,pt2);
AcDbDatabase *pCurDb;
AcDbBlockTable *pBlockTable;
pCurDb=acdbHostApplicationServices()->workingDatabase();
pCurDb->getSymbolTable(pBlockTable,AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId Id;
pBlockTableRecord->appendAcDbEntity(Id,pLine1);
AcDbAlignedDimension *pDim1 =new AcDbAlignedDimension(pt1,pt2,pt2,NULL,Id);
pBlockTableRecord->appendAcDbEntity(Id,pDim1);
pBlockTableRecord->close();
pLine1->close();
pDim1->close();

pCurDb=acdbHostApplicationServices()->workingDatabase();
        pCurDb->setDimblk("_OBLIQUE");//设置两侧箭为斜线
        pCurDb->setDimtxt(0.5);//设置文字高为0.5
        pCurDb->setDimtsz(0.25);//设置斜线长为0.5＝0.25*2
        pCurDb->setDimdsep('.');//设置小数点为.
        pCurDb->setDimzin(0);//设置前、后缀零
        pCurDb->setDimexe(0.5);//设置尺寸界线超出量为0.5
        pCurDb->setDimexo(3);//设置尺寸界线偏移3
        pCurDb->setDimgap(0.2);//设置文字偏移0.2
