I'm hoping someone can explain to me why this is happening.
I've created a toolbox that contains a model in Model Builder to complete a bunch of steps repeatedly. It's just a bunch of selects and calculates on a layer to set attribute values.
Although there are many processes (... 320 total), I'm not understanding why the toolbox is so large. Everytime I open the toolbox, open the model for edits, or save the model, it takes about 20 minutes. I'm not talking about actually running the model, just opening, editing, and saving.
I thought the model was just a set of paramaters and processes to run, but there must be something more going on in the background that I don't know about.
I've cleared all the results from the Results tab to see if that helps, but it doesn't.
