I will give that a shot, thanks for the input!
I'll give some details to the problem that I was having and maybe you can answer where it would still arise if all three were combined into a single script.
I had to separate model 1 and model 2 at one point because the output contour feature class (created within the model) that was used as the input in a polyline to raster tool would throw an error that says "Cannot retrieve the feature class extent" before the model was even allowed to run. If I cut the two models at that point, run model 1 which ends at the contour creation, and then run model 2 starting with the contours as the input, it runs fine. I can see how it would say it couldn't retrieve the extent since the contours aren't technically created yet, but I find it weird that ArcMap won't allow the model to even begin to run at all.
The second break ends in the creation of a Minus raster, and begins with the Reclassify tool. For some reason if I put these two steps together, it won't work...but if I run model 2 up to the Minus raster creation, and then start model 3, it works just fine.
I'm not sure if that will all make sense without seeing what I'm working with, but maybe it will.
Thanks again for the input!
