Trying to make a simple model, but getting an odd error

Hi all,

I need to run a bunch of viewsheds that are going to take some time to compute. I'd like to set them up so that they will run sequentially overnight. I figured that the best way to do this was with ModelBuilder. Now I've never used this before, but I read some tutorials, watched ESRI's video on Youtube, and what I am trying to do is very simple. And this is the error I get when I try to run my test model. It gives me the little yellow "I'm ready to go!" shading, but then breaks immediately. I haven't even added a second process, and I'm not quite sure how, but that's a problem for later.

I'm baffled. When I turn and run the exact same process through the geoprocessing tab, it works just fine. My data is not the problem here. I probably made some very elementary mistake here. Does anyone know what might be wrong?

Hi Aurelius,

Since the same process runs just fine in the Geoprocessing tool, it's possible to just drag the successful geoprocessing result into a new Model and try running that. That copies all parameters just as they were run in the tool into the model. It's a generally a good way to troubleshoot a model process.

Here's the workflow: 

  • Open a new Model
  • In the Catalog pane, click on History
  • Find the successful Viewshed geoprocessing result (denoted by a green check)
  • Click and drag the result into the Model pane.
  • Save and run the model.

If that works, it's possible that a parameter was just entered incorrectly. 

I'm hoping that helps you move forward! 

Happy modeling!
