I'm using ArcHydro which, I think, uses the Spatial Analyst (SA) functions. One function is "Flow Path Tracing" too. This traces a graphic line where the water would flow based on the flow direction grid.

My problem is that the graphic line does not appear again until I zoom out. At this level of zoom I can't see enough detail to may the traced flow path worth analysing. When I zoom in  the graphic line disappears.

Anyone deal with this one?
