如何将用wblock命令导出的块添加到图纸中？

pengyh 发表于 2006-5-31 22:17:00

我在一个dwg图纸中做好了所有的块，然后我用wblock命令将这些块保存成dwg文件，那么我在需要的时候就可以直接将这些块添加到我的其他的dwg文件中，可是在程序中如何实现插入以dwg格式存放在磁盘某个位置的块呢？

问题我已经通过广大无私人事的帮助终于完满的解决了，再次公布出来给大家共同分享，同时感谢帮助我的朋友们！
Acad::ErrorStatus insertBolck(const char *blockName) {  //将块从文件读出，添加到当前数据库中  AcDbDatabase *pNewDb =new AcDbDatabase(Adesk::kFalse);
 Acad::ErrorStatus es = pNewDb->readDwgFile("C:\\Documents and Settings\\pengsl\\My Documents\\ARX\\Step01\\TEL_CD.dwg" , _SH_DENYNO,false);  if (es!=Acad::eOk)  {   acutPrintf("\nThe file  cannot be opend");   return es;  }
 AcDbDatabase *pDb =acdbHostApplicationServices()->workingDatabase (); // pDb->insert(AcGeMatrix3d::kIdentity, pNewDb );这样添加的块是打散的，而且也没有自定义属性。    AcDbObjectId blockId;    if((es=pDb->insert(blockId, "TEL_CD",pNewDb, true))==Acad::eOk)  {   acutPrintf("\ninsert ok\n");  }  else  {   acutPrintf("\nInsert failed");   delete pNewDb;   return es;  }
 //将块从当前数据库中添加到图纸中并且显示出来，此时块还不具备自定义属性  AcGePoint3d ptOrg(10,10,0);     AcGeScale3d XrefScale(10,10,1);
 AcDbObjectId blockTelCdId;  AcDbBlockTable *pBlockTable;  pDb->getSymbolTable(pBlockTable, AcDb::kForRead);  pBlockTable->getAt("TEL_CD", blockTelCdId);
 AcDbBlockReference *pBlkRef = new AcDbBlockReference;    pBlkRef->setBlockTableRecord(blockTelCdId);  pBlkRef->setPosition(ptOrg);  pBlkRef->setRotation(0.0);//设定转角  pBlkRef->setScaleFactors(XrefScale);//设定放大比例
 AcDbBlockTableRecord *pBlockTableRecord;    pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForWrite);  pBlockTable->close();    AcDbObjectId newEntId;    if((es = pBlockTableRecord->appendAcDbEntity(newEntId, pBlkRef)) != Acad::eOk)  {   acutPrintf("\n something is wrong");  }    //处理新加块的自定义属性值  AcDbBlockTableRecord *pBlockDef;  acdbOpenObject(pBlockDef, blockTelCdId, AcDb::kForWrite);  AcDbBlockTableRecordIterator *pIterator;  pBlockDef->newIterator(pIterator);  AcGePoint3d basePoint;  AcDbEntity *pEnt;  AcDbAttributeDefinition *pAttdef;    for (pIterator->start(); !pIterator->done(); pIterator->step())//将source.dwg中所有的Attibute进行遍历  {         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("J001/zg01/003");             AcDbObjectId attId;             pBlkRef->appendAttribute(attId, pAtt);             pAtt->close();         }         pEnt->close(); // use pEnt... pAttdef might be NULL     }  delete pIterator;    pBlockDef->close();  pBlockTableRecord->close();  pBlkRef->close();
 delete pNewDb;  return Acad::eOk; }

这个函数封装的太差劲了

^_^，我也承认封装的很差，这个函数只是用来完成功能的，没有考虑其它很多

 嫩为大家提供一个封装的较好的函数吗？
