So let's see. The next question we have then is from Ricardo, and he's saying, “Is there a limit on
the number of processes and elements that you can have in a model?”
The only limitation, Ricardo, is your imagination. So whatever you need to put into your model
diagram, you can have in there. Keep in mind though, and I'll make a suggestion to you that I've
made to other people, that, just like you would do if you were creating a file structure in Windows
Explorer on your computer, you would have a sort of a plan in mind where you would have
things broken down into folders and then subfolders and so on. I would recommend that you do a
similar sort of thing with your models as well. Break them down into workable units. It will make
your life a lot easier when it comes to trying to make changes or if you need to do any kind of
editing, or if you need to fix things in that, and then you've got each one of those smaller models
being called in another model. So, sort of break it down into workable units.
Our next question is from Terry, and he says, “Can you demonstrate how to create a custom script
tool that runs in AML?”
Well due to time constraints, Terry, we can't demonstrate that for you, but I won't leave you
empty-handed. I'm going to tell you this: Go to the Desktop Help System, open that up, and there
is a book under there called Writing geoprocessing scripts. There is another book underneath that
called Messaging and script tools, which contains a page called Using AMLs with script tools.
This will explain everything to you and actually give you a step-by-step process on how to get it
done. So, there’s plenty of information there for you for that.
Then we have a user in West Lafayette who says, “Can I use ModelBuilder and a script together
in tandem?” I want to make it very clear to everybody—because this is something that a lot of
newer people have trouble with—that there is no difference between a system tool that we
provide you or a custom tool, such as a model and a script that you use. So yes, they can be used
together. You can drag and drop script tools into your ModelBuilder interactive window and use
those to build your workflow—no problem. And then inside of your script, you can also call a
model tool, just like you would call one of our system tools, so there’s no difference there. So
there's the answer to that question as well.
I think we'll pass it back to Jeff now.
