Landscape Path Modelling - 3D - Rhino 7

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

Thank you so much sir!! I hope you keep posting such helpful tutorials. Thanks from India 🙌

[@tombudd15]

Thanks, im glad they are useful!

[@byShawnPark]

This was indeed very helpful. Thanks Tom! Essential for landscape architecture students.

Thanks Shawn, I am glad you found this useful

This is AMAZINGLY helpful merci

09:00 Best practise is to contour the terrain by 1m contours and use them as height and shape guides to create the path curve. Anything else can easily lead to unexpected lows (digging) or highs (building) of the path.

[@constantinosschinas4503]

14:40, We can also create a patch surface from points, and project the original flat curve to it.

[@constantinosschinas4503]

15:00 extrude line vertical, then offset surface both sides, solid option on.

[@constantinosschinas4503]

14:00 Easier to select all points, nudge by 1, deselect first, nudge by 1 using gumball (remembers last value), and so on. A few hundred clicks faster, and less prone to error.

Thaks, greate!

Hello, first of all I love your videos. They have lot of new things to learn and I learned a lot of new stuff after watching your videos. In this particular video, if you could in future make few tutorials on how to make such a quad mesh terrain with such variations and also how to create quadmesh based objects instead of regular triangulated mesh geometry of rhino. Thanks in advance!

[@tombudd15]

Thanks, glad you have found the videos useful! And many thanks for the suggestion, I have a video on creating terrain from contour lines you can find here: czcams.com/video/UbPtPznTicU/video.html and I also plan on making a similar video on using SubD tools in Rhino

Is there a way to "undo" the boolean? I mean, if I did all these step and then I realize I'd like to change the way of the river, for ex, how can I do it?

15:55 that profile was not exactly tangent to the path start. Extent end of path by line and use that line to rotate your profile.
