求助，如何用AO或AE来处理shp文件

我有两个shp文件，一个是图版，一个是山脊线，我想要用山脊线文件叠加在图版文件上，然后用山脊线文件来分割图版文件，比如如果一条线穿过了一个图版，就把此图版分割成两个新的图版，请问大家用AO或AE怎么实现啊？

<P>可以利用要素的编辑功能来实现</P>
<P>利用线找到穿过的一个图版,然后把此图版分割成两个新的图版,下图为分割要素的一个例子</P>

  pFeatureEdit.Split pPolyLine
  Set pFeature = pFeatCursor.NextFeature
Loop</PRE><PRE>End Sub</PRE></CODE></PRE></PRE></PRE>

利用上述代码分割多边形时，它在pFeatureEdit.Split pPolyLine里提示出错“a polygon cut operation could not classify all parts of the polygon as left or right of the cutting line"我的线和面文件在一个featuredataset里

我也出现了楼上的这个问题，始终解决不了，请高手出场啊！

这个问题提示很清楚了,被分割多边形或线必须是被分割线分成两部分,即所谓的左边和右边.
