I am building a model to process between two and five files (the number of inputs changes depending on the scenario). I would like to have the option for the users to input up to five files, but toggle on/off unneeded inputs as required.
Each input is processed the same way (define projection, add field, calculate field, project and buffer) and then the two to five files are merged at the end.
Batch processing is not possible however as the calculate field is based on a variable entered manually per file (Machine Tail Number) (IE input file 1, name variable 1. Input file 2, name variable 2 etc.)
I have tried to implement a toggle on/off using a boolean precondition. However this just stops the process, a data input is required for the validation check.
Can anyone think of a way to toggle on/off inputs?
Do you have any suggestions?
