Is there a trick to using the "Change Flow Direction" in the pipes menu? Trying to follow the command line directions, nothing appears to happen to the flow direction arrows.
When it says to "Select the UPSTREAM starting point in plan (Pipe or Structure):", I've selected the pipe near the upper manhole structure or the upper manhole structure (not on the same try). When directed to "Select the DOWNSTREAM ending point in plan (Pipe or Structure):, I've selected the pipe near the lower manhole structure, the lower manhole structure, or the pipes in between the upper and lower sections on the lower ends. If it comes back with any response to what I've done, it's "Flow direction sucessfully applied to 0 pipes.
Does it automatically make the flow go downhill with the terrain? I need to change the flow direction to go against the terrain.
Any help in this area is appreciated.
