AE中如何将面状地物转化为点状地物

arctoolbox里有工具Feature Vertices To Points (Data Management)

也可以利用ae的接口来获取到polygon上的节点来转换成点;用 ipointcollection 得到vertices.然后把 feature的shape 等于ipointcollection 变量.在pointcollection里你可以得到poygon的所有节点

dim pPointColl as iPointcollection
pPointcoll=new polygon
dim pfeat as ifeature
'get the feature.......... then assign it
pPointColl =pfeat.shape
