It's worth mentioning that this tool works only with ArcMap that is an Advanced license level.
Dear axin1026@
I have your toolbox on "River center lines" is downloaded and added to the Arc Toolbox, I am very happy with these tools because I can use for a lots of things to make a lot of biking trails (bike paths / polygons), but how can I use these tools. I send a clipped ArcToolbox where the tools were in with a red and that means I can not use this tool. while the other tool (centrepoint on lines) usable. would you please help me with this problem, I have arcgis 10.3.1. advance.
thanks for your help,
John Rumambi
