Definition doesn't work

Hi everyone,

I have just started using grasshopper a while ago and i'm still quite new at this, so I've been trying out different online tutorials. I found one that gives me really a hard time here:

https://vimeo.com/35519338

I managed to work out the same definition but i must be doing something wrong cause it doesn't work.

Maybe somebody here knows something to fix it? I have attached the files bellow if you could have a look.

Hello Maria,

Michael Pryor (the uploader of the video) is an active member of this forum (profile) so you can bring this to his attention.

I am not sure I can tell how exactly the two [shift list] components work but I believe you can achieve this by culling the last item(-1) on one list and shifting the other by 1. (and of course grafting the 2 lists which you forgot to do).

Check the file:

Added some "restrictions" more on that one (and options). Align planes (as usual) it doesn't work - or has some logic beyond my imagination - when curves are non planar (case 1): compare with case 0.

Thanks guys! I think I'm now close enough to what was shown in the tutorial! I'm really excited with this software even though I need to practice it much more to actually understand the logic.. Is there any book or series of video tutorials I can find for beginners to help me learn? I found quite a lot tutorials on vimeo or youtube, but most of them I think are quite advanced and even though I can recreate the definitions they work with, I can't always understand the logic, in order to help me make something on my own..

I keep getting stuck when I try making my own definition as I don't know how to use all the tools to get full control of what I'm doing..

No worries! I thought the best way was to go on youtube, but I have now checked the tutorials section in this website and it actually gives tones of learning material!
