How to make a 2:1 slope on a topographic drawing?
-
Is there a method or plugin to create a specific slope on a curving, irregular, line?
I have a topographic plan that I've imported into Sketchup.
I drew the lot boundaries with a 10' offset and projected them onto the topo.
I need to create a 2:1 or 3:1 slope towards the center of the site.
The best method would be something like a chamfer where I can specify the angle.
(I've already tried: Follow Me, 1001bit tools slope and it's version of follow-me, extruding and scaling the bottom face, and fredo6 roundcorner.)

I don't normally try to make specific edits to topography. instead if I have a topo or if I have a structure, I will build the new topo and then build the geometry from it.
Does this have to be precise? can you not manually make the changes? If so the sandbox tools will help greatly. or if you want to spend the best $25 of your life you can buy Vertex Tools. http://www.thomthom.net/software/vertex_tools/
here's a list of land editing tools I've made.

I made the list of tools... Not the tools... I make no tools, I just point people towards people who make great tools.

check your links, some URL's looks like they're truncated, not working

Thank you Krisidious. None of those programs do what I need.
I do have to be exact, it is part of the Building Code.
I am trying to figure out site placement of a home and reduce the amount of retaining walls.
In the picture I attached, the green surface is the existing Topo. i need to slope everything towards the center of the shape, from that black line drawn on the topo. That line isn't on one plane, so it isn't a single contour line.
Manual doesn't work because there are probably a thousand points.

The approach is more about what sort of terrain object you need in the end. Shall it be evenly divided in quads or simple faces? How is it to be blended with the rest. How clean is the form? In most cases, given that I have an existing terrain, I would make a very rough model of the area to be "graded" and how it would blend to the non-graded areas. I would use Artisan sculpt tool, mostly using "flatten" with shift key to approximate the model on a copy of the existing terrain. This is imprecise, but most like the final grading would occur at a house site.I would try to maintain a quadrilinear grid of the terrain.
But there are other ways, such as using a simple angular model then smoothing it with Artisan. You might make a uniform terrain afterward using Instant Terrain.
You might use my little tool
