Has anyone shared a ModelBuilder model on GitHub? I was curious if there was a way to collaborate on a custom ModelBuilder tool using GitHub and then bring it back into ArcGIS as a tool? ... without converting the model to Python.
I too am looking for collaboration on ESRI modelbuilder uses. I've collaborated outside on GitHub several times by exchanging toolbox files (*.tbx) but you really have to watch the version of ArcGIS you're using to create the model. Models can use python files as tools or not. Hope this helps.
To compliment Chris Woodward's reply a model can only exist inside a toolbox (*.tbx) so the only option is to share a tbx file. Exporting a model to python defeats the purpose of it being a model in model builder!
Also when sharing models you need to be aware of:
You may want to take a look at the Geoprocessing Package options available in Desktop...there are some options to help with collaboration by being able to pass a model(s) and the data being used among multiple people.
