If I have a terrain map with topography information (either Fusion or Carbide Create grayscale height map) is there a way to trace a line on that map for a road or trail that follows the terrain? I know I can create the shape by rastering back and forth across the whole terrain, with the ball end mill dipping in and out of the trail as it comes across it, but the line would look better and cut much more efficiently if it could just trace trail itself from start to finish.
Any ideas? Updating the grayscale height map will only give me the raster solution. Drawing a separate vector will lose the Z-axis information. How can we draw a vector in 3D space that the tip of the end mill will follow?
