Failed to load surface

Grasshopper
1

I’m really new in grasshopper.
I want to use ‘LUNCH BOX DIAMOND PANEL’. But I can’t load my surface in grasshopper.
I tried to ‘SET ONE’ and ‘SET MULTIPLE’ but I can’t.
What should I do?
attached my work. 2.3dm (1.4 MB)

Yours is a polysurface(ie, a Brep), not a surface type, so you can’t refrence it by using Surfaceparameter. Use Brepparemeter instead…
BTW, If you try to use one of Lunchbox panels onto your Brep, you’d better use Deconstruct Brep together and apply lunchbox panels to individual surfaces respectively.

Thanks! I’ll try it:)
