深度拷贝将数组中的实体ID指向的实体拷贝至blockId为ID的块中
AcDbIdMapping adimIdMap;
AcApDocument* pDoc = acDocManager->curDocument();
acDocManager->lockDocument(pDoc, AcAp::kWrite);//锁定当前文档
acdbHostApplicationServices()->workingDatabase()->deepCloneObjects(ptarr, blockId, adimIdMap);//克隆当前选中的实体到块中
acDocManager->unlockDocument(pDoc);//解锁文档
//同样用于拷贝AcDbObjectIdArray 中的实体对象到owner指向的实体中。

AcDbObjectIdArray& objectIds,
