Gridshell

hi,

i'm not familiar with kangaroo and want to learn it now.
for this i have taken the interesting work of Han Byul SEOL as basis,
to work on b.z.w. to vary it.

http://www.grasshopper3d.com/group/kangaroo/forum/topics/flexible-g...

i've now created a cylindrical gridshell.

unfortunately, the effect with varying the different opening
dos not work. i don't no what is my mistake.

can someone give me an advice?

p.s. in my def. you can also find the def. made by Han Byul SEOL!

thanks

rassul
