nts but as there are polylines and surfaces in it, they are conflicting as the geometries are overlapping and intersecting.
The input for the model is a centre point and four connecting points: we can call them CNT, A, B, C and D. The model works for these points - it's quite complicated with lots of polylines, vector geometry, surfaces, rotations, etc. - but it still works and has an output of two breps.
If I had a compilation of N sets of CNT, A, B, C and D's, is there a way of feeding each of these into the grasshopper in individual sets rather than just plugging in the huge set of numbers - e.g. feeding in CNT1, A1, B1, C1 and D1 and getting a result before moving on to CNT2, A2, B2, C2 and D2?
I've tried looking through tree structures, but it seems to be failing when the size of the set isn't known - e.g. how to extract all the information from trees when N isn't know using list item (i=0, i=1, i=2..., i=N).
I hope I've managed to explain the problem adequately, I can make up an easier to understand Grasshopper model later if I haven't explained well...
Thanks in advance for any comments, pointers, etc.…
product_info&cPath=17&products_id=68). It's a little light on sensors, so you may want to look through the sensors page on the adafruit website and choose a few that look interesting to you. If you have a little more money, here are two other kits which have many more components that will help round out your electronics supply. Here is a good one for around $85 (http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=170). And here's another great one from SparkFun for around $95 (http://www.sparkfun.com/products/10173). Of course, you can buy an Arduino Uno for around $29.99 and you can purchase each of these components separately and only choose the ones you need (and perhaps save some money)... but these are pretty good kits which include all the stuff you need to get started. Good luck.

ing; 95% of all the available tutorial material seems to be from an earlier build, like .7 or something.
Hexagonal Grid is a lot different with it's inputs and outputs changed a lot, and yeah I know Vector multiplication is now assumed by the ordinary one use serves all multiplication function but still generally this issue is the only confusing thing in the entire program which is otherwise quite clear. And it's not just these functions...there's quite a few I'm bumping up against and it's really eating into my study time to have to search and search for the substitute which is often the exact same function with a new name. I know there has to be change to have progress but...
I've tried to think my way around this and after a lot of work on various tutorials I've eventually forced things to work but I really wish things hadn't been thrown out with such brutal haste.
Thus I was wondering; is there an earlier build available that would allow me to go back to say, the Grasshopper Generative Modeling For Rhino tutorials? Link?
Sorry to bother you with this but it would really hasten the learning process..…

y differences that are inconsequential to me, choosing one or the other appears to simply be a matter of a choice in programming style.
I've been active on this forum for a couple of months now. From the cross section of my interests, about 95% of the scripts I've encountered are written in VB rather than C#. My natural choice would be to learn C# because I took some C++ in college and I like the refined style. But I'm a little concerned about learning C# with respect to GH because most of the stuff here is in VB.
Is it just coincidence that Grasshopper users happen to come from other arenas that use VB more? Or, am I missing something that I should know before learning how to script for GH?
Also, once you learn one language well, is it fairly simple to read into and do minor hacking or tweaking in the other, since they are based on the same libraries?
My questions are fairly straight forward. I'm trusting that people in the GH community can keep their cool more than on most forums when a "this versus that" question is asked. Thanks for your understanding.…
