Hi. I have an existing model which is used in ArcGIS Desktop 10.3 which I would like to improve.
To use the model the user chooses a start and end point on the map and the model then calculates distances using different methods. The start and end points have been configured as feature sets and are interactively entered from the model tool dialog box.
The issue I have is that there is nothing stopping the user clicking more than once and ending up with multiple start and end points. This provides a poor user experience and breaks the model.
Can anyone tell me whether it is possible when using feature sets to restrict the user to only creating one feature? Alternatively, can anyone suggest a neat way of taking a feature set with multiple features and reducing it to one feature?
