Next DownID won't assign

MichelleTischler — Thu, 16 Aug 2012 21:01:19 GMT

Hi! I'm using ArcH 1.4 and trying to assign the next downstream ID/Junction. When the dialog box opens, it will not allow me to choose the HydroID field to assign from. It only shows the Enabled field. I created the HydroID field as a Long Integer and have been able to build a relationship class with it. It's pretty frustrating bc I've been able to do this before and not sure what I missed this time.

Thanks for any help,
Michelle

I thought I'd try and clarify what I've done to see if that might help in finding a solution.

I've built my geometric network with one set of points (proxies) and one set of streams and used the Attribute Tool to assign the HydroID to each. We have a custom tool that assigns the Junction ID (Proxy Hydro ID) to the lines. Then I generated the From/To node for the lines, found the next downstream line, and calcluated the length downstream for edges and junctions. Now I want to assign the next downstream junction to the Proxies (points). When I open the dialog box and select my points, the only option I have for the Common HydroID field is "Enabled."

Any suggestions would be helpful. Thanks,
Michelle

Problem solved. I didn't assign a HydroID to the network junctions.
