Hello guys 
I’m a student in architecture major and have lots of interest in grasshopper.
Now I want to make an optimization process that stacks a unit(I’ll attach the photo).
What I’m thinking about is that if I input a mass, then the code stacks a units to the form similar to the input mass.
My unit looks like as the photo attached, and I’ll also attach a grasshopper code(compatible with Rhino 7) describing my unit.
Can anyone give me some clues for realizing this idea or some references for this one?
Thank so soooo much in advance
