[求助]

我想在ArcGIS8.3 Desktop下进行拓扑处理,步骤是:
ArcCatalog下新建Geodatabase,Geodatabase下新建feature datasets,feature datasets下新建feature class,请问怎么在feature class中加入数据?或如何在feature datasets中引入feature class?我试了好多次都没办法把原有的feature class拖入feature datasets中,系统老是提示失败.使我一直不能运行topology.
请各位指点,我该怎么做?

点右键import，选择你要导入的数据类型

<P>谢谢！我刚才总算试验成功了。</P>
