//插入块 void insertBlock(AcGePoint3d basePoint,char *blkname)
{
AcDbObjectId blockId;
AcDbBlockTable *pBlockTable;
if(!hasThisBlock(blkname)){
AcDbDatabase *pDb = new AcDbDatabase(Adesk::kFalse);
pDb->readDwgFile(blkname);
acdbHostApplicationServices()->workingDatabase()->insert(blockId,blkname,pDb);
delete pDb;
}
else{
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable, AcDb::kForRead);
pBlockTable->getAt(blkname,blockId);
}
AcDbBlockReference *pBlkRef = new AcDbBlockReference;
pBlkRef->setBlockTableRecord(blockId); struct resbuf to, from;
from.restype = RTSHORT;
from.resval.rint = 1; // UCS
to.restype = RTSHORT;
to.resval.rint = 0; // WCS
AcGeVector3d normal(0.0, 0.0, 1.0);
acedTrans(&(normal.x), &from, &to, Adesk::kTrue, &(normal.x));
pBlkRef->setPosition(basePoint);
pBlkRef->setRotation(0.0);
pBlkRef->setNormal(normal); AcDbObjectId newEntId;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable, AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,AcDb::kForWrite);
pBlockTableRecord->appendAcDbEntity(newEntId, pBlkRef); pBlockTableRecord->close();
pBlockTable->close(); pBlkRef->close();

} 调用 char *block_name="c:\\arxprjmfc\\heada.dwg";
char tbuf[80];
AcGePoint3d pt1; if(acedFindFile(head_name,tbuf)!=RTNORM) { //在盘上查找图块
sprintf(tbuf,"file <%s> not existed.",block_name);
acedAlert(tbuf);
return RTERROR;
}
else{
pt1[X]=0.0;
pt1[Y]=0.0;
pt1[Z]=0.0;
insertBlock(pt1,head_name);
}
