    // Return distance in 3D space.
    length[k]=acutDistance(pt[k], pt[k+1]);
    rest[k]=length[k]%100;//求余数
    integer[k]=length[k]/100;//求每一段整100的个数

   AcDbLine*pLine=new AcDbLine(AcGePoint3d(startpt[j][0],startpt[j][1],0),

    } 
    pLine->setColorIndex(1);//红色
     AcDbBlockTable *pBlockTable;

     pBlockTable->close();
     AcDbObjectId lineId;
     pBlockTableRecord->appendAcDbEntity(lineId,pLine);
     pBlockTableRecord->close();
     pLine->close();
}

//ads_point pt[4] 为全局变量

请各位高手帮帮忙，是点没转化好，还是acutPolar函数返回的值没有呢？

好好学习下C++， 括号放错位置了：

    for(int j=0;j<3;j++)
    { 
         acutPolar(pt[r], rads[r], 100*j, startpt[j]);
   acutPolar(startpt[j],rads[r]+3.1415926/2,50,endpt[j]); 
   AcDbLine*pLine=new AcDbLine(AcGePoint3d(startpt[j][0],startpt[j][1],0),
                 AcGePoint3d(endpt[j][0],endpt[j][1],0));
  //  }错误地方
    pLine->setColorIndex(1);//红色
     AcDbBlockTable *pBlockTable;
     acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForRead);
     AcDbBlockTableRecord *pBlockTableRecord;
     pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
     pBlockTable->close();
     AcDbObjectId lineId;
     pBlockTableRecord->appendAcDbEntity(lineId,pLine);
     pBlockTableRecord->close();
     pLine->close();

    }//正确地方

非常感谢老牛～～

一直困扰了我很久啊～ 我还以为里面的函数用错了
