In ModelBuilder I require the user select 1 of 5 feature class layers as the initial feature class to run the rest of the model on. The selected layer is to be then fed into a clipping tool as the Input Feature

How do I create a drop-down list of layers in the tool selected from ones I have set the file path for?

I want to have 5 feature class layers selectable as the input for the clipping tool.

  • Are all your input layers held in the same workspace? – Hornbydd Dec 16 '18 at 1:46
  • the layers are held in a Feature Dataset within a Geodatabase connection. – FRMMO Dec 17 '18 at 10:03
  • Does it need to be a dynamic list, read from a workspace? Or is it the same 5 over and over? If that's the case you can make and hard code a list on inputs – KHibma Dec 17 '18 at 13:07

I don't believe the type of functionality you are asking for is possible in pure ModelBuilder environment. To create a parameter that offers up lists you would have to build a script tool that feeds into a python script. If you want even more control then a python toolbox script is probably a better solution.
