ERROR 10118 - Distance of zero encountered on breakline, check for cooincident vertices

Description

Two consecutive vertices on a breakline are at the same or nearly identical coordinates, resulting in a zero distance between them. This prevents elevation interpolation along the breakline.

Suggestions

Open the breakline GIS layer and check for coincident or duplicate vertices. Remove or merge any duplicate vertices and rerun the simulation. The GIS output shows a point on the affected breakline.
