Hello forum! I want to use grasshopper to show the direction of curves and surfaces like rhino, as shown in pictures. Hope to get help, thank you in advance!
Evaluate Surface and Evaluate Curve components will get you normal vectors on a surface and curve respectively.
Then it depends on how you want to display it. whether through grasshopper’s planes or with the render tools with the rhino library.
The WombatGH plugin has Curve and Surface direction components, if you want to go that route.

Thank you all for your answers!
Hi, Sergeer. Thanks for sharing your script. Do you think it would be possible, when you have time, to share how you did it, please? I’m trying to understand Python, but I’m not able to replicate your script.
