[求助]AE怎么实现对Coverage polygon的切割

要在程序中实现Coverage数据中多边形的切割和拼接，主要是拓扑关系怎么建啊？  总统来看一下哇    等着呢   ~~~~~~

<P>用 Intersect方法，试下</P>
<P>————————————————————————</P>
<P>NOTE: This tool only works with an ArcInfo license and will only be available in ArcToolbox if you have installed ArcInfo Workstation.</P>
<P>Intersect creates a new coverage by overlaying the features from the input coverage and intersect polygon coverage. The output coverage contains the input features or portions of the input features that overlap features in the intersect coverage. The output features have the attribute from the original feature from the input coverage and the feature in the intersect coverage, which they intersect. </P>

<P>能具体点不？</P>
