Split surface doesn't work

[Uyan_Yuna]

Hi, I am working on my assignment trying to create a pavilion design. At the moment I have run into a new issue in my GH file: Data conversion failed from Curve to Surface which ends up not creating the surface I need for the next steps.

I created the surface on Rhino and used random points and then BREP but splitting doesn’t seem to work. I tried both split brep and split surface.
Please help.

the problem you are facing is that you are plugging a Polysurface where you are supposed to input single surfaces (it’s indeed called Surface Split, not Brep Split )

one way to solve it could be to explode the Brep into single surfaces, split each of those using the heart-shaped curves, pick the residue fragments with biggest area and join those together back into a Brep again:

Hi, @jessesn
After applying the shape, the hearts are not hearts anymore, is this the limitation or there might be some trick to get the hearts?

Hi @Quan_Li try to give a smaller size to the Length.

@Uyan_Yuna You can give a try with ShapeMap, @Quan_Li made a good demo for you. Thanks @Quan_Li

Thank you very much! That works.
I don’t understand how the base lines affect the shape. May I ask for your brief explanation?

Here, what affects the shape of the curve is not the baseline, but the value of Length. This is a value of samping distance of curves. Used to control the accuracy of the cure fitted to the orginalsurface. Please to go to below papge to downlaod the demoe file of ShapeMap and you can find the more details about it,

About the ShapeMap category

This is a group for the ShapeMap plugin: ShapeMap | Food4Rhino [image] About ShapeMap ShapeMap is a plugin for Grasshopper. It integrates multiple basic functions in Rhino and has undergone secondary development. This plugin allows users to map any curve texture designed on a plane onto the surfaces of complex 3D models, while minimizing or eliminating deformation of the texture curves on the 3D surfaces. With ShapeMap, designing textures on 3D model surfaces becomes much easier, and the oper…

Omg Thank you soo sooo much Inno, you even fixed my project. This saved my assignment.
I appreciate you.

Hello, Quan Li, I have no idea why it’s changing the shape it also happens when I try to randomize, but thank you so much for helping me. I appreciate you.

Thank you Jessesn, this helps a lot.

distortion on the heel part.gh (145.7 KB)

I want to map the hexagon lines to the foot with the ShapeMap. The hexagons on the heel are distorted badly; I wonder whether there is a way to avoid this overly uneven mapping.
