Gyroid Oriented Bbox Intersection with Curved Mesh

Hi everyone.

I am using Millipede and Weaverbird plug-ins for this.

The first picture and .gh file below is that of an intersection of a gyroid box with a normal box. The visualization is satisfying, with a nice gyroid panel as a result.

In the second picture, I have tried to do the same thing but with a curved mesh.

Firstly, the gyroid formation is stretched, which does not give a nice visual result.

Secondly, I cannot split the two meshes in order to obtain the curved gyroid panel.

Could anyone help me out? Thanks.
