Hi! I have created a model for DEM processing to extract hydro logic flow path and basins and then I saved the model as tools in a tool box. But when I recall the tool for another processing, that comes in model builder as single tool which is not editable and if I link that tool with another DEM file it can not provide any different output. So, all I want to know is, how to save the model of model builder and recall it for another data and along with that I want to edit the model where its needed.
