Thank you Dan. I think my problem is a quite common one, and not focusing on buffer, i.e. whenever I tried to use geoprocessing or arctoolbox to do something, warning000117 came. The help put this: [The output created or modified has no features. A common occurrence of this warning occurs when the Extent (or  XYDomain) environment has been set previously for a geographically distinct area. Since the Extent environment is used to limit the features used, an inappropriately set Extent environment could exclude all features.] So I tried to change my extent environment, I went to geoprocessing, then environment, then processing extent, I changed the processing extent in a few ways. But still warning000117. What is your advice? Thank you. ... View more
