Using Relative Item for Patterning

I am utilising the video tutorials by ExLab for the subject 'Studio Air' at the university of Melbourne. The video (if anyone would like to watch it) is 5.03 Tree Menu (https://vimeo.com/60594155).

I am trying to use the relative item component as a means of creating patterns on surfaces. At around 8 minutes in the video talks about using relative item and I have followed the tutorial step by step and have the exact same script as they show in the video yet I cannot get any patterns to be produced (i.e. having a sphere, and using relative item to create diagonal lines rather than horizontal/vertical). (See screenshot).

Please have a look at my script, I've made it self-contained in grasshopper. Would really appreciate if someone could please explain why the poly lines will not appear and why the relative item component isn't working?

Hmm ... I'll prepare a small ("simple", he he) tutorial on that matter.

In the mean time: are you by accident familiar with C#? (I have lot's of examples about creating lot's of patterns [any pattern imaginable, in fact] using solely code).

Unfortunately no, I'm quite novice to grasshopper but I am very keen on learning as much as I can. If you would be happy to share these C# pattern examples for me to learn when I get onto C# that would be really great.

If you like, please email to matthew.tibballs@gmail.com :)

OK, get an intro on that matter (C# VS patterns) made for a friend who has C# in his future plans (BTW: Intro is a relative thing ... he he).

If and when you are attracted to the Dark Side I'll mail you some other ("internal" so to speak) far more complex cases.

Also get a primitive intro to Rel Items (and Split Tree) using components (very old test case: I don't use components any more).

best, Lord of Darkness
