A path with slopes on the terrain

Min/Max Slope Pathfinder in Kangaroo

I think it helps to think about the geometric aims here and when they conflict. If the target length is low, this keeps the curve closer to a straight line. Clearly a straight line cannot lie between the 2 fixed end points on the curving surface - just because a destination is 100m away at 10m greater elevation doesn’t mean a route exists that can drive you there at a constant 1:10 slope. Because the 2 aims are conflicting, their relative strengths will control which one is violated more. If …
