Topo generation question

[KENTUCKY]

Is there a method or plugin that will limit the distance a triangulation line travels in the z direction?

I have a very difficult terrain which has a series of very steep road edges. The sandbox tool and toposhaper plugin are not yielding usable results. Toposhaper grid can't be made small enough to accurately display the steep slope. Sandbox tool is jumping multiple countour elevations to triangulate.

Alternatively, perhaps there is a plugin that will divide all of the topo line segments to a maximum distance that could be set at 6 inches or so. This would eliminate much of the contour lines being jumped over.

Thanks

It is always difficult to reconstruct terrains with sharp relief. Instead, the best is to create the base terrain and then add the roads and other extruded relief (via Sandbox or other plugins).

Thanks for the reply.
I was able to get better results using a program that limited the distance of the triangulation lines and then bringing that into sketchup.
Ultimately though we ended up sending the file back to the surveyor to obtain additional break lines to use. We were able to get a usable topo.
Thanks again
