Curb and gutter along a road w/terrain?

ntg84

I'm new to terrain modeling in SU, and I have a site that I'm trying to show the existing conditions at. I've got a CAD survey that I brought in and created terrain from contours. Then I used drape to place the road and sidewalk. But its flat....and not smooth looking. Can you make realistic roads with curb and gutter? Heres an example
see the jaggedness of the road....any ways to get a smooth or smoother road? I cant find any good tutorials out there on this issue....any links would be cool too.

Well, as I'm not able to create whole tut on this right now, I can only give a couple of tips on this. What I'd do is not to use the drape tool in this case but the stamp tool like the steps below:

crete the terrain as you have already created;
use the contours of the road to create a face (hopefully they are coplanar and forming a closed loop)
move it down to the highest point of your terrain
divide the face with additional lines and/or use the autofold feature to rotate the other parts of your road face as close to the terrain as possible - but only in very general
when you're done and the road is smooth enough (but obviously "floating" above or "submerges" below the terrain, select all and use the stamp tool to integrate it into your terrain.
soften edges where necessary
In the "realy world", roads are either running higher than "valleys" or cut into hills so that they don't beed to follow smaller details of the terrain. This will be the result with your road, too.
