Daniel,

many thanks. I didnt realise that the pull to mesh component had the same/similar functionality and overlooked it first time round.

I did get some great results from kangaroo so thanks. I had been speaking with my tutors (DS10 at westminster) who had suggested the scripted approach may provide a way to achieve denser results, but i did manage to get the following from kangaroo after my initial forum response on this thread. I will have a go with the pull to mesh approach and really appreciate kangaroos functionality! Thanks for your input! :)

Regards,

Chris

Hi Chris,

just wondering how did you create that image above? I suppose those are all the water lines generated?

What is the T in your grasshopper component?

Hello everyone,

I am a total beginner with Python, Rhino and Grasshopper, but I need to model the drainage paths on a surface.

I imported a .jpg file into grasshopper and created a Surface from Points. Now I tried to use your python script to model the drainage. 

When running the script it appears the Runtime error 'terrain surface' is not defined. 

But to be honest I am not sure if I even did connect the Python component correctly with my surface and further on then imported the surface correctly into the skript. 

As I said, I am a total beginner and I would really appreciate any help.
