Has anyone had problems with using the "trace feature by NextDownID" in the latest ArcHydro version (2.1) under ArcGIS 10.1? I have created an ArcHydro Network and try to select catchment polygons by tracing upstream from a HydroJunction, as well as select drainage lines by tracing upstream from a downstream segment. In all cases, only the HydroJunction or drainage line segment I have clicked with the trace tool gets selected, nothing upstreams.
I have used this tool in the same way ever so often under ArcGIS 10 with earlier ArcHydro versions and never had problems. Couold this be a new bug?
Best regards,
Irene
