[image] [image] [image] i m not able to figure out mesh intersection as i proceed. Its actually giving the direction of flow over terrain. but it comes as invalid and outcome is messy lines. i m using anemone for this flow analysis. can someone help me.

[image] output is like this… which is nout true i feel

Share the simplified GH, so people can look into your problem.

Hi @JENIL_Sarvaiya Try Bison. [image] Bison Bison is a landcape architecture plugin for Grasshopper + Rhino 6. It features tools for terrain mesh creation, analysis, editing, and annotation.

Okay, I will try that out too… Does that work in a similar way as this? that would be great.

It has a spacial component for flow direction of water. https://www.bison.la/ [afbeelding]

Will this plugin work in rhino 7?

yes in Rhino 7 it works fine, but the pluginn is discontinued and I heard it won’t be working anymore in rhino 8.

That’s not a good news, what alternative do we have?

[image] Road on Terrain Grasshopper Bison has several interesting tools. Too bad it’s no longer maintained and won’t work on Rhino 8 when that’s run in the NETCore runtime. -wim
