I'm trying to create a flood-out map with ArcHydro and ArcGIS 10... I do all of the preprocessing and I make sure that all my data is projected correctly, but when I go to create a 3D line under utilities, the FROMZ and TOZ fields contain the same number... I know for a fact they're suppose to be staggered like normal slope... any help or thoughts would be greatly appreciated.
To clarify: I notice this behavior when the line is composed of only 2 vertices such that one WSE point covers the start (FROM) vertex and another WSE point covers the end (TO) vertex. The corresponding line in the Output Line 3D has Shape_Length = 0 and the TOZ = FROMZ such that the FROMZ = the value of the WSE point that covers the start (FROM) vertex.
