DTM @ Retaining Wall


JRoth

Recommended Posts

On 8.5.2, I'm attempting to generate a fairly straightforward DTM of a small but steep site from contours. With some fiddling, I got 3D polys as I want them, but when I attempt to create a DTM, it gives me errors for having overlapping & coinciding x,y coords. I believe that the program is unhappy with the 2 places where there are existing retaining walls, and the contours therefore follow the wall - one over top of the other.

Is this, in fact, the problem? And if so, how do I resolve it?
