前段时间有篇名叫《编程日记(1)ARX中如何insert一个图》的文章怎么没看见了？？
还有我按照上面的思路写了一段程序，但是插入后，autocad当前窗口中没有我所插入的图形！请指教！！

程序代码如下：
void InsertBlock()
{

char bName,pfName;
int es;
AcGePoint3d Pt(0,0,0);
double Angle = 0.0;
AcGeScale3d XrefScale(1,1,1);

strcpy(bName,"first");
strcpy(pfName,"F:\\FENGH\\program\\AutoCAD\\ObjectARX\\LibMag\\libmag.dwg");

AcDbDatabase *pDbMS = new AcDbDatabase(Adesk::kFalse);

if(pDbMS->readDwgFile(pfName) != Acad::eOk)
{
acutPrintf("\nThe file %s cannot be opend",pfName);
return;

}
// pDbMS->getBlockTable(pBlockTable,AcDb::kForRead);
// pBlockTable->close();

AcDbDatabase * curpDb = acdbHostApplicationServices()->workingDatabase();
AcDbObjectId blockId;

if((es = curpDb->insert(blockId, bName,pDbMS, true)) == Acad::eOk) //´ÓÊý¾Ý¿â²åÈëÍ¼¿âÖÐ
{
acutPrintf("\ninsert ok\n");

}
else
{
AfxMessageBox("Insert failed");
delete pDbMS;
return;
}

AcDbBlockReference *pBlkRef = new AcDbBlockReference; //´´½¨Ò»¸ö¿é±íÒýÓÃ
pBlkRef->setBlockTableRecord(blockId);// Ö¸ÏòblockId;

pBlkRef->setPosition(Pt);//ÉèÖÃÎ»ÖÃ
pBlkRef->setRotation(Angle);//ÉèÖÃ×ª½Ç
pBlkRef->setScaleFactors( XrefScale);//ÉèÖÃ·Å´ó±ÈÀý

AcDbBlockTable *pBlockTable;
curpDb->getSymbolTable(pBlockTable, AcDb::kForRead);

AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId newEntId;
pBlockTableRecord->appendAcDbEntity(newEntId, pBlkRef);
pBlockTableRecord->close();

// delete pDbMS;
acutPrintf("\nprogram begin add attribute\n");

AcDbBlockTableRecord *pBlockDef;
acdbOpenObject(pBlockDef, blockId, AcDb::kForRead);

AcDbBlockTableRecordIterator *pIterator;
pBlockDef->newIterator(pIterator);
AcGePoint3d basePoint;
AcDbEntity *pEnt;
AcDbAttributeDefinition *pAttdef;
for (pIterator->start(); !pIterator->done();
   pIterator->step())//½«source.dwgÖÐµÄËùÓÐAttibute½øÐÐ±éÀú
{
   pIterator->getEntity(pEnt, AcDb::kForRead);
   pAttdef = AcDbAttributeDefinition::cast(pEnt);

if (pAttdef != NULL && !pAttdef->isConstant())
{
         AcDbAttribute *pAtt = new AcDbAttribute();
         pAtt->setPropertiesFrom(pAttdef);
         pAtt->setInvisible(pAttdef->isInvisible());
         basePoint = pAttdef->position();
         basePoint += pBlkRef->position().asVector();
         pAtt->setPosition(basePoint);
         pAtt->setHeight(pAttdef->height());
         pAtt->setRotation(pAttdef->rotation());
         pAtt->setTag("Tag");
         pAtt->setFieldLength(25);
         char *pStr = pAttdef->tag();
         pAtt->setTag(pStr);
acutDelString(pStr);
         pAtt->setFieldLength(pAttdef->fieldLength());
         pAtt->setTextString("-");

         AcDbObjectId attId;

         pBlkRef->appendAttribute(attId, pAtt);
         pAtt->close();
   }
   pEnt->close(); // use pEnt... pAttdef might be NULL
}
pBlockDef->close();
delete pIterator;
delete pDbMS;
acutPrintf("\nprogram end!\n");

}

Sorry, 误删,可能是kForRead不对,也可能要锁定文档.

goldenshin 发表于 2003-4-22 11:49:00

不可以这样

运行InsertDwgFile()后,得到一个ID,创建一个AcDbBlockReference, 并将它指向ID所代表的AcDbBlockRecord, 然后将这个AcDbBlockReference加入pDb所代表的图形数据库中.
你的程序中,得到ID后,没有操作这个ID.
