Using checkbox on ModelBuilder tool to control adding to data frame?

Question

I have a geodatabase feature class and every day I want to automate the loading of my feature class into a data frame of my map.

At present in my model (below) I add into my data frame the geodatabase feature class but I want to add a checkbox option.

i.e. choose whether to add or not the feature class using a checkbox

enter image description here

This is only part of the tool that I want to do.

This feature class contains reference points for an analysis of service area, which is the reason why I want to automate the data load.

Can I use a checkbox on my tool dialog to control whether, when the model runs, its output feature class gets added to the display (data frame)?

Answer 1

You could add a Boolean variable and expose it as a parameter then connect it as a precondition to the Make Feature Layer. This will allow ALL layers to be loaded if TRUE or none of them if FALSE.

Example model of a precondition controlling order of operations

I don't think you can control each layer as this would require you to interact with the model on every iteration and model builder does not work that way.
