新人来请大侠们帮助，arcmap中如何用一条线来切割一个面？

大侠们可要帮小弟一下啊。。

用编辑工具里的split工具

<P>多谢老大对新人关怀倍至,小弟要多多努力,争取以后也可以帮助别人.</P>

<P>用cut  polygon也可以</P>

cut  polygon,功能菜在哪能找到啊.

<P>editor/task下有</P>

收到!!多谢...我所说的线割面,是两个ship文件,通过叠加运算,产生新的ship.就是split. 可是我这个功能用不了.是不是要装workstation才可以啊!

<P>你在arctoolbox里用split工具就可以是完成不了你的任务的</P>
<P>只能打断线，你可以在arcmap里编程完成</P>

<P>代码如下，在帮助里找的</P><PRE><P>The following VBA code fragment illustrates how to implement the appropriate calling behavior on multiple features within a set..</P><CODE><PRE> </PRE><PRE>‘Assume pSet (ISet) and pMoveVector (ILine) already exist.
Dim pUnknown As IUnknown, pFeatureEdit As IFeatureEdit
Set pUnknown = pSet.Next</PRE><PRE>Do While pUnknown Is Not Nothing
  Set pFeatureEdit = pUnknown
  pFeatureEdit.MoveSet pSet, pMoveVector
  Set pUnknown = pSet.Next
Loop</CODE>
</PRE><P>The following code is an example of one way you could split a selected polygon features by a polyline.<CODE></P><PRE>        </PRE><PRE>Public Sub SplitFeatures(pSelectionSet As ISelectionSet, pPolyLine As IPolyline)</PRE><PRE>‘ open a feature cursor on the selected features that
‘ intersect the splitting geometry
Dim pFeatCursor As IFeatureCursor
Dim pSpatialFilter As ISpatialFilter
Set pSpatialFilter = New SpatialFilter
Set pSpatialFilter.Geometry = pPolyLine
pSelectionSet.Search pSpatialFilter, True, pFeatCursor</PRE><PRE>‘ Clean up the splitting geometry
‘ This is necessary because, for polygons, IFeatureEdit::Split
‘ relies internally on ITopologicalOperator::Cut
Dim pTopoOpo As ITopologicalOperator
Set pTopoOpo = pPolyLine
pTopoOpo.Simplify</PRE><PRE>‘ Loop through the features and split them
Dim pFeature As IFeature
Set pFeature = pFeatCursor.NextFeature</PRE><PRE>Do Until pFeature Is Nothing
  Dim pFeatureEdit As IFeatureEdit
  Set pFeatureEdit = pFeature
  pFeatureEdit.Split pPolyLine
  Set pFeature = pFeatCursor.NextFeature
Loop</PRE><PRE>End Sub</PRE></CODE></PRE>

哇！老大你真是太热心了，多谢，多谢！！小弟离编程有段距离，但是看到你们用起编程来巨牛无比，好是羡慕，小弟定会潜心研究的。
