Hello, I´m trying to do a simple dissolve task in Model Builder 10.1 which worked fine in ArcGIS 10. It also works as desired when I use the tool outside the Model Builder. Strangely, besides the fact that the number of features is falsely increasing after running dissolve, the output is singlepart although I checked the multipart option and the input is a multipart feature class. Any suggestions? Thanks!
