Making wood art using electrical field

Hi
I’m new with grasshopper but I’m learning fast
I try to make a wood art like the picture below, I used spin field and merge field to make something similar to the picture and i think it’s fine. but i don’t know how to make a bulge with curves so to have surfaces and make it with CNC machine, i used 2rail sweep in rhino and was fine for most of the curves except cross-like, even curve network didn’t work. can you please share your advice and help me in this project?
Sorry for my broken language :wink:
Regard
