objectarx之遍历当前模型空间中的所有实体，并对每个实体进行炸开

mac2022-06-30 16

//炸开void BomEntity(){ AcDbBlockTable *pBlkTbl; acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlkTbl, AcDb::kForRead);

//获得模型空间的块表记录 AcDbBlockTableRecord *pBlkTblRcd; pBlkTbl->getAt(ACDB_MODEL_SPACE, pBlkTblRcd,AcDb::kForRead); pBlkTbl->close();

//创建块表记录遍历器 AcDbBlockTableRecordIterator *pItr; //块表记录遍历器 pBlkTblRcd -> newIterator(pItr); pBlkTblRcd->close(); AcDbEntity *pEnt = NULL; //遍历的临时实体指针 for(pItr->start();!pItr->done();pItr->step()){ //利用遍历器获得每一个实体 pItr->getEntity(pEnt,AcDb::kForWrite);

//块参照 if (pEnt->isKindOf(AcDbBlockReference::desc())) { //炸开 AcDbVoidPtrArray ents =Explode(pEnt); //循环遍历炸开的实体 for(int i = 0; i < ents.length(); ++i) { AcDbEntity* pSubEnt = (AcDbEntity*)ents[i]; AcDbEntity* entity = AcDbEntity::cast(pSubEnt);AppendToDatabase(entity); entity->close(); } pEnt->erase(); }

pEnt->close(); } delete pItr;}
