I am trying to use the "Select layer by location" tool, in Model Builder, ArcGis.
This tools has 2 input files: "Input Feature Layer" and "Selecting Features".
I cannot connect the "Input Feature Layer".
When I drag and drop the "Connect" arrow (which is used to link layers to tools), The tool only shows "Selecting Features" (Fig. 1). Ok... I have tried to open the tool, and choose from there, the "Input Feature Layer", but it creates a duplicate of that layer (Fig. 2). By creating a duplicate, all the steps of this model stop at this particular step.
What can be causing this error? I work in ArcGis 10.2.2 and use no extensions.
