CAA已得到草图，如何得到里面的东西

如图所示，已经得到了"草图.1"
是：CATBaseUnknown_var CurrentFeat
如何得到其下面的几何参数
如图中圆的圆心坐标

图如下

图怎么这么难贴

  CATListValCATISpecObject_var spSketchCycleList;
  CATListValCATISpecObject_var spSketchCycleCenterList;
  do {
        CATIDescendants_var spDesc = spYourSketchAsBaseUnknown();
    if ( !spDesc ) {
      break;
    }
    spDesc->GetDirectChildren("CATI2DCircle",spSketchCycleList);
  
    for ( int ii = 1; ii <= spSketchCycleList.Size(); ii++ ) {
      CATI2DCircle_var sp2DCycle = spSketchCycleList[ii];
      if ( !sp2DCycle ) {
        continue;
      }
      CATISpecObject_var sp2DCycleCenterPoint = sp2DCycle->GetCenter();
      if ( !sp2DCycleCenterPoint ) {
        continue;
      }
      spSketchCycleCenterList.Append( sp2sp2DCycleCenterPointDPoint );
    }
    
  } while (FALSE)
  
大概可以用这个思路，未验证

acoka兄：
         这段代码我研究过了，有个问题请教一下：在这句：
spSketchCycleCenterList.Append( sp2sp2DCycleCenterPointDPoint );  
中得到了草图圆心列表，请问怎么样才能把所有的圆心显示出来？谢谢你一直指点。
