Hello! I have scanned some length of a local river bed for some Hydraulic Design. For less complex situations, I would use some projected surfaces to model the vertical faces of the river bank. My question is, would a Radial Surface be more effective since the river bends multiple times? If so, how do I accomplish this task? I have followed Alan Sharp's quick video on using the Radial Surface for a wall, but those steps seem to yield a surface that does not create any vertices. I have attached a couple of screen snips to help illustrate.
