I am a beginner with SketchUp, but usually manage to find the answer to my questions by digging through the web. I am however not able to find any good solution to my current problem.
I have created 20 different layers for 20 contours to get the 3D-map I need (1 layer per meter above sea level). Further I have drawn a road which I would like to fit on the existing contours. Could anyone point me in the right direction?
Check out the “Drape Tool” in the Sand Box Tool Kit. I have never used it but it is for exactly what you want to do. I think you can easily find a video tutorial on this tool.
