In the screenshot, the red surface is the road, and the purple and green surfaces are topography surrounding said road.
With the purple topo, I manually set the points to match the road but I was wondering if there are quicker ways to achieve this result with the green topography. I’ve uploaded my file as well.
If you just need the green to touch the red without modifying it, you can use Move command with the Vertical Option activated and just bring everything down
If you meant to have a cliff wall or something, you can use the edge surface command and create a wall between the road and the green hill
If you want to modify the green hill you can use the MatchSrf command and make it touch the road modifying the green one
If you want to create another kind of cliff wall than a straight one, you can use BlendSrf to create surfaces with variable options.
that would not work since its a trimmed surface, MatchSrf requires untrimmed Surfaces
there might be something that brings you pretty close, its not perfect but the edges are really close enough to be cleaned up manually after that.
first use DupBorder on the road, then make a straight line along the open end and use this curve to split the previous boarder then use patch, no need to join the curves that might just make it difficult for patch to work now you have your target surface
