生成直线的ARX在执行命令时出错

Gary_damingming

生成直线的ARX在AutoCAD加载成功，但是执行myline 命令时出现     内部错误：！dbobji.cpp@7227 eNotOpenForWrite  
   程序是下面的
  AcGePoint3d ptStart(0,0,0);
  AcGePoint3d ptEnd(200,200,0);
  AcDbLine*  pLine =  new AcDbLine(ptStart,ptEnd);
             AcDbBlockTable  *pBlockTable;
    acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlockTable,AcDb::kForRead);
    AcDbBlockTableRecord  *pBlockTableRecord;
    pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForRead);
    AcDbObjectId  lineId;
    pBlockTableRecord->appendAcDbEntity(lineId,pLine);
    pBlockTable->close();
    pBlockTableRecord->close();
    pLine->close ();

希望高手指点

生成实体要用写操作，你把 AcDb::kForRead  改成 AcDb::kForWrite
