Hi everyone,
I was trying to make a weavy surface ; using split tree in order to make arches . By saing that, with dividing a curve, eather in even numbers or odd numbers I’ll need to exclude last number or (n-1) number, which in dynamo you can easily get them by using codeblock!.
what’s the right syntax to get last number parametrically in grasshopper?
This is extraordinarily complex for such a simple objective, but rather that re-writing it, see white group:
Use the tree statistics component to get a list of tree branch paths and cull index the list by number -1 (which is for indexing the last item) and use it for the tree branch component.
my point is get myself more invovled with data trees and writing syntaxes . Cuz I’m right now getting confused a bit using Dynamo logic and trying it in Grasshopper. that’s why I used this logic!. Thank you for your help as always by the way!..
Thank u Ali jan,so helpful!
Always keep it simple 
P.S. Your preferred solution is an image without GH code? 
ofcourse not 
Yet that’s the thread solution you chose. I normally don’t care about such things but an image without code leaves many questions. And it’s not the simplest method for shortening a list.
There are many ways to create this wavy surface, of course - as always. This one ignores how three points are chosen, which affects location and orientation, amplitude and wavelength.
Still, it’s very simple by comparison.
what do u mean an image without code? by saying syntax I just meant to work with operator syntaxes like we do for path mapper ,relative items and so on. Maybe there is a misunderstaning here between us!
Apparently so.
Congrats.
for?
Congrats. For using a cracked license.
set free sanctions from my country and then we can talk more about it!
Which country?
congrats!!
Russia?
you know nothing about ,how people struggled in many sanctions should survive and find a way to communicate with rest of the world! cuz u re livin in a free society !. R we gonna talk about data trees or politic datas? cuz i have no interest about it! tnx.
u should make me more congrats cuz while I’m writing to u is thanks to VPN!!!. So, go and have fun man!
You’re right about this.
Sorry and good luck.
