Convert Contour lines to 3D Terrain in Rhino

Learn about how to turn 2D contour into 3D editable topography in Rhino 3D! This method works with topography on a larger scale and can get accurate surfaces from existing contour lines.

We will be using grasshopper for this tutorial, but don't worry as it's very simple!

The main commands covered are:
- delaunaymesh
- reducemesh
- drape
- grasshopper

Can you explain how you generated the contours with height values? That would be super helpful to help us get started. Thanks!

Subscribed because of this video! I'm transitioning to Rhino, and this video has saved me a huge amount of time. Thank you! I would love to see more tutorials on terrain modeling.

relly useful, one of the most difficult thing on rhino is to make natural terrain, thx

[ravemasters]

It is very simple and well explained, as it would probably be most useful to architect students, you could perhaps include a tutorial on how to place buildings in scale. it would just make it more valuable :) . thanks again for another great tutorial that helped a lot.

Omg you save me days of work, thank you

It is very helpful, 🙂 loved the video. Also thinking of new shrinkwrap feature of rhino 8

I am doing a project surrounding a 700 ft deep mining pit and I think this will make my life so much easier trying to modify the contours and terrain to place my building on the edge of the pit and turn one of the contour lines into a path. do you have anymore tips that could help as i do this

Hey this was very helpful, tysm. I could make the mesh and the drape, but I would like to ask if there is a way once I use the split command to extrude the rectangle with flat/straight tap instead of with the curvature of the drape

[flashgames]

you can also quad remesh insted of drape

[behradinfinity]

Nice man! I think your Indesign tutorials are more popular, hit them with new creative ideas, good luck.

I diiiiddd Ive already done been subscribing

Awesome video, I have been trying to follow the steps carefully but I do not get the desired results. I have the contours as dfx file, I imported the file to rhino, followed the steps in Grasshopper and unfortunately do not get the mesh to further apply drape commend. please need help

[jennyliang]

thank you for the video! but i’m having trouble with manipulating the drape, when i select a curve to split it it keeps saying split failed, any advice?

1. Insufficient points for triangulation. You need at least 3.?

How did you get these contours? Please help me.
