怎样得到样条线的拟合点数据？

• 回答：

      var ent = mxOcx.GetEntity("选择样条线");
      if (ent == null)
          return;
      if (ent.ObjectName == "McDbSpline"){
          var spl =ent;
          var fitPoints = spl.GetFitPoints();
  
          for (var i = 0; i < fitPoints.Count; i++)
          {
              var pt = fitPoints.Item(i);
  
              alert(pt.x.toString() + "," + pt.y.toString());
          }
      }
