[ARX程序]：关于AcDbFcf怎么没人提提意见呢?

vinyar

程序要提取图纸中的公差信息,,，假设有两个公差标注,其数据分别为0.001，和0.02


我根据联机帮助使用了函数
double
dimtxt() const;
未能实现。

显示的结果为4.358634   4.358634
而不是0.001   0.02


我不知道为什么会出现这种情况.
是不是因为上面的函数用错了，还是别的什么原因，。
哪位知道的请求帮助！！void fitol()
{
// TODO: Implement the command
AcDbBlockTable *pBT;
if( acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBT, AcDb::kForRead) != Acad::eOk)// 得到块表对象
return;

AcDbBlockTableRecord *pRec;
if(pBT->getAt(ACDB_MODEL_SPACE, pRec,AcDb::kForRead) !=Acad::eOk) //获得模型空间块表记录
return;
pBT->close();
Acad::ErrorStatus es;
AcDbBlockTableRecordIterator *pIter;
es=pRec->newIterator(pIter); //得到块表容器的迭代指针
AcDbEntity *pEnt;
AcDbFcf *pFcf;
// AcDbDimStyleTableRecord *pRecord;
int i=0;

for (;!pIter->done();pIter->step()) //开始遍历
{
es=pIter->getEntity(pEnt,AcDb::kForRead);//得到实体
if (es!=Acad::eOk)
continue;
//判断是否是指定层和指定实体LINE
if ((!stricmp(pEnt->layer(),"0"))&&(pFcf=AcDbFcf::cast(pEnt)))
{
i++;
acutPrintf("\n第%d个公差标注的值为:%f\n",i, pFcf->dimtxt());///这里出错了
}
pEnt->close();
}
acutPrintf("\n **********共有%d个公差标注**********",i);

delete pIter; //释放叠代指针
pRec->close(); //关闭块表记录
return;
}

use AcDbFcf::text(...), pls:
==============================

AcDbFcf::text[/COLOR] Function virtual char *

text(

const int lineNo = kAll) const;

lineNo Input line number (zero based) of line of text desired. If the lineNo parameter is not present, then all lines are returned (with carriage returns between each line)

Each tolerance frame is one line of text, so, for example, a stack of two tolerance frames:

  ----------------
| // | 0.001 |      <-- frame 1
|----------------
| O  | 0.005 | M |  <-- frame 2
  ----------------
would have a line 0 (frame 1) and a line 1 (frame 2).

Warning The caller of this function is responsible for deallocating the string returned by this function (acdbFree() should be used).

这个提示是帮助里面的，我看过了。

但不知道该怎么对定义line0，和line1
