This video tutorial goes through the steps to model sloping paths at consistent gradients within a landscape using Rhino 7. The key steps in this video can be found below:
Straight Path Creation
00:00 - Introduction
00:30 - Working out the gradient required for you path
02:00 - Working out how to alter the terrain to make this path gradient
02:20 - Making the path using the 'Sweep1' command
03:40 - Excavating paths of the terrain using the 'boolean difference' tool
04:12 - Building up the terrain using the path sweep
Curved Path Creation
06:40 - Sketching out the path route
07:55 - Drawing out a smooth curved path
09:35 - Checking the path length using the 'length' command
10:28 - Flattening a curve using 'SetPt' command
10:55 - Dividing the line into equal sections to set to a constant gradient
11:45 - Setting the vertical height of the points using the 'Nudge' tool
14:00 - Drawing a curve through these points
15:00 - Modelling the path using the 'Sweep1' command
17:05 - Excavating paths of the terrain using the 'boolean difference' tool
