Hi ​@elmido13 

In my mind I would want to say there must be some way to set this up. For each point dissolve all lines downstream of the point, then use that dissolved line to select all points along and then do the calculation. Buuuut, for actual tracing tools I think ​@j.botterill covered it with his answer a little while ago.
 

Hi ​@elmido13 ,

I think you can use NetworkCostCalculator to achieve the goal in this case. The process would be a bit long story, see the attached workspace example to learn more.

​@takashi Thank you for your assistance. I truly appreciate it. I will review the WB and learn from it. I’ll let you know whether this addresses the issue discussed here.

​@crutledge Thank you for insight. I truly appreciate it. 

​@takashi the example you give me. Help solve my problem. Thank you so much. Really appreciate the help.
