DESCRIPTION 

Here we dispatch the items from a list into two target lists based on a list of Boolean (true/false) values. This allows us, to e.g. to find points within a particular range.  

PROCEDURE 

1.Create a slider that allows you to locate any point on a curve. Reparametrise the curve by right-clicking on the icon.  
2.Calculate the distance from all points in a point list to this curve point.  
3.Check if this distance is below a specific parameter  
4.Dispatch the list of points into two lists: those closer and those further away than the selected parameter.
