      Hello everyone,

      So I know generally how to create a road on terrain. The problem with the methods I found is that if you put a road directly across (not through) a slope, the curb lines on both sides would result in very different heights causing the whole road surface tilted (along the slope or more complex geometry) unrealistically.

      Thus is there a way or plugin to stabilise/even a road surface as it follows the terrain geometry only on the direction the road goes? I searched for such plugin for some time as well as some online tutorials but never found a solution. Basically, it is like putting the correspondent points on two sides of a road section onto a same Z axis value.

      I wish someone have already got an easy accessible solution.

      Best,

        I'd use the native Sandbox tools to drape your kerb rail onto the terrain.

        Extract the draped profile so you can create its surface then Stamp that.

        Download the free D'oh Book for SketchUp 📖

          Drape tool is useful but it is not necessarily suitable to the scenario I have encountered. To use the tool as you explained (many thanks for it), I still need to figure out the roads' detail heights manually before apply it onto a mountainous terrain.

          The thing is if I have a terrain generated from contours and road plan which is totally flat, there is no way drape tool can put the road network correctly following the terrain, not the other way around.

          I hope there is a tool which can stamp the road plan onto an uneven terrain while maintain/allow editing roads' surface.

          Thanks again,
