请教我这段代码，从数据库中读取DWG文件 如何获得AcDbMText坐标

lhf1973

//创建一个空白的图形数据库
//注意该处AcDbDatabase()函数的参数必须为Adesk::kFalse
AcDbDatabase *pNewDb =new AcDbDatabase(Adesk::kFalse);
//将指定文件名的图形A件读入到空白的B形数据库中
const char* sFileName="c:\\AA.dwg";

Acad::ErrorStatus es=pNewDb->readDwgFile(sFileName , _SH_DENYNO,false);
if (es!=Acad::eOk)
{
acutPrintf("\nThe file %s cannot be opend",sFileName);
return;
}

//获得块表指针
AcDbBlockTable *pBlockTable;
pNewDb->getSymbolTable(pBlockTable, AcDb::kForRead);
//获得模型空间的块农记录指针
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForRead);
pBlockTable->close();
//生成块表的迭代器
AcDbBlockTableRecordIterator *pIterator;
pBlockTableRecord->newIterator(pIterator);

AcGePoint3d basePoint;
AcDbEntity *pEnt;
AcDbMText *pAttdef;
char temp[200];
int i;
i=0;
for (pIterator->start(); !pIterator->done();
pIterator->step())//将source.dwg中所有的Attibute进行遍历
{
i++;
itoa(i,temp,10);///
// acutPrintf(temp);
pIterator->getEntity(pEnt, AcDb::kForRead);
if (pEnt->isKindOf(AcDbMText::desc()))
{
// acutPrintf("第% AcDbMText ",i);
// acutPrintf("\n\n");
pAttdef = AcDbMText::cast(pEnt);
if ( !( pAttdef->contents()==NULL) )
{
acutPrintf(" AcDbMText: %s \n" ,pAttdef->contents());
获取坐标
// basePoint = pAttdef->position();
// acutPrintf(" AcDbMText: %Ld %Ld %Ld\n"
// ,basePoint->X(),basePoint->Y(),basePoint->Z());
}
}
pEnt->close(); // use pEnt... pAttdef might be NULL
};
delete pIterator;
}

你的问题是??


AcDbMText *pAttdef;往下放,放在你需要的地方,并且你一旦不需要马上关闭.

谢谢 我想请问如何获得AcDbMText坐标？

dipenghao

pAttdef->location()不是坐标吗？

谢谢 两位 最后可以执行的代码。

不太会用

ok?
