I am trying to split polygons that are overlapped using "split" from analysis tools, however several of these polygons are not properly split. I double-checked that the name of each of these is different by creating a short name (less than 10 characters), however there are several errors (several polygons in one *.shp file). I also used model builder, and the result is not better. I have to do this for 3900 polygons, so I don´t want to do it manually. Some one has any suggestion, please? Thanks a lot.
