(Brep plane& Surface Split) Is there any way to apply Planes on the Certain surface?


My goal:
I would like to make a certain panel division as below image.
Firstly I used lunch box, but I couldn’t make it.
Because Surface split was not working. (probably I did something wrong)

So I simply made Grid curves to split Surfaces. Because I would like to move the blue part with different number compared to white color parts.


It seems the Planes of the surfaces applied to other side of surfaces.
I tried to use Surface Split component too. The result was same.

Here are GH and Rhino file:

Could anyone give me any thought to solve this issue?
Thanks for you help in advance.
