Gyroid structure with millipede

Hello
if Eval doesn’t work (don’t you see the red color ?) there are surely no input in Millipede components (they still work)
A get "2cos"is not understood, try “2*cos(x) …”

Gyroid works well here


cos(x)*sin(y)+cos(y)*sin(z)+cos(z)*sin(x)

2.75*(sin(2*x)*sin(z)cos(y)+sin(2y)sin(x)cos(z)+sin(2z)sin(y)cos(x))-(cos(2x)cos(2y)+cos(2y)cos(2z)+cos(2z)cos(2x))

0.5*(sin(x)*sin(y)+sin(y)*sin(z)+sin(x)sin(z))+0.5cos(x)*cos(y)*cos(z)

Thank you Laurent.

Im still very new with grasshopper, and dint know it was an issue.

Ive tried the 2* part, and still not working.

Hello
I don’t mind the YouTube video, there must be an error in the expression. A line jump, an empty line …
Could you post your file ?

i see, apologies for the inconvenience. This is the file.

It was what I though => an empty line. In order to see it augment the size of panel, select all (CTRL+A) =>


This is not good
Go to this place, Delete it and now you have a complete unique line

Just took it off from hotbed.
So this is cos(x)*sin(y)+cos(y)*sin(z)+cos(z)*sin(x).
