Matt,
I cannot see the model inside the toolbox in version 10.0. However, I moved to a 10.1 machine and can access it. I ran the model exactly as you have it with the point3 file and it worked as expected. I replaced your point3 file with my file and reran the model and it is currently running through all the iterations. It may take it awhile to complete, but I will let you know the results when it's complete. Thanks for you help on this. I'm beginning to think something in my 10.0 installation was the problem.
BTW are you the same Matt Payne from WKU?
