I am relatively new to ModelBuilder and null in python. I want to include Merge tool in my model. However:
- at run 1, I want to Merge shapefiles s1 and s2
- at run 2, I want to Merge shapefiles s1, s2 and s3
- at run 3, I want to Merge shapefiles s1, s2, s3 and s4 etc.
How can I include this to my modelbuilder model? I know how to make it manually, but how to make it in the model?
I can't just set the "Merge" as Parameter, and I don't see to option to make it via "Make Variable".
Exported python snippet :
