next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

ll geometry.
The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process.
In this little model, the starting point actually is a bit obvious, the foundation.
The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters.
Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor.
You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH.
Anyways, here's a screen capture of the foundational lines:
In the first group of components, the centerlines of the rear columns are modeled:
And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly.
The same was done for the rear columns:
The above, believe it or not, took me the first 5 hours to get.
Here's a screen capture of what the model and definition looked like after 4 hours, not much:
If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really.
I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…

13;2} ... 20.{13;12}
21. {21;0}22. {21;1}23. {21;2} ... 41. {21;20}
42. {34;0}43. {34;1}44. {34;2} ... 75. {34;33}
76. {55;0}77. {55;1} ... ....
I want to grab the first 8 [0-7], the next 13[8-20], the next 21[21-42] etc
so i have the (known fibonacci seq) list of numbers on the left here:
C S
8 0
13 8
21 21
34 42
55 76
89 131
144 220
233 364
and i need the list on the right, so that i can select items using a Series (N=1 and S and C from the list above) and a List Item component.
the simple question is:
is there a component that can take a list and accumulate it in this way that I need?
if not, is there anyone that can point me to a simple relevant VB example so i could easily adapt it?
many thanks,
gotjosh…
correct:
- the right value in the 0. path {0;77} is the smallest one.
- right value in the 1. path {0;78} is the value which is closest to the chosen value in the preceding path
- ..and so on for {0;79} and {0;80}
but when the paths change their first level, the iteration should start from the beginning:
- right value in the 4. path {1;32} is the smallest one.
- right value in the 5. path {1;33} is the closest to the chosen one in {1;32}.
- right value in the 5. path {1;34} is the closest to the chosen one in {1;33}.
..to be continued.
..this is, what I want to achive in the VB code, I implemented at the beginning of the discussion.
..and this is how I designed the input-parameter of the VB-element:
if someone could help me .. super-great!

Mac due to its versatility , but given this new laptop will be using mainly on Rhino, GH , i have some doubts whether to switch to a window based laptop.
I have a look at some high-end window laptops, Dell Alienware for example, with same specs as MBP and found the price are even more expensive than MBP , about 10-15 %.
With the new Rhino 5 is coming , will Bootcamp be good and efficient enough to run Rhino, GH and some rendering programs?
From my experience i find Rhino and Gh run smoothly on Bootcamp , but never run those programs on window based laptop myself , it's impossible for me to know the differences.
Some say BootCamp only deliver 80% performance of the program , if it's true i would really consider switching to window based laptop.
Any suggestions?
and if you suggest me to switch , what brand should i go for ?
Thank you,

tunities offering new tools and ways to understand dataflow, performance analysis, logic constructions, etc. Over that statement, I've always observed that a definition is full of information at component level or small groups, but that informed-user-feeling disappears exponentially while you zoom out an get a more general picture of a big definition (small definitions are not a problem due to the good level of information supplied at that zoom factor).
So I though, why not to use this graphic potential to lead to a more complete data representation at low zoom factors in big/very big definitions? Have you ever noticed how annoying is to review big definitions captures printed in A1 project panels? These captures lack any kind of useful information (even if you are an expert in GH)...you can only conclude looking at them how organized or well planed was the definition coding process...but nothing else (not really, you can conclude other stuff, but not at the level that you could expect from a graphic-centric coding tool). Some users has invented ways to give more data to third-person users/tutors...: using panels with text scaled up, using scribble components, importing drawings from rhino...is even more frustrating if you want to explain how the definition works using one of those captures...there are not landmarks, etc to support your speech.
All this lead us to include certain components search (by name, plugin, tab...) into our mapping tool. Could be nice to be able to stack several layers of information visually, and it could lead to a better understanding on GH definitions as a whole and not as small pieces linked together.
Sorry for the big "tocho"...like we say in Spanish.
By the way, the histogram thing sounds great :D…

uld draw, lets say opening locations which would then trigger certain code. Its fairly easy to convert formating, a cell with a certain color, to code, so in a way I would be using excel as a super basic cad program to manage lists of data. In order to do this I need to be able to call some Excel commands from Rhino and to add some functionality to LAN's rhino to excel script (http://www.livearchitecture.net/archives/1516) I would like to be able to get the Ubounds and dimension of an array or a list. . . ie somehow get the equivelenat number of rows and columns of an incoming list of data and then use this to generate some graphics in excel but . . . . It seems that the sytax for excel Vb script via interoperability
marshaling is a bit different:1)I can not use
the set command ie Set range 2) it does not allow me to use the typical excel
syntax such as:
Worksheets("Sheet1"). Range("A1:D4").BorderAround
ColorIndex:=3, Weight:=xlThick
I get the following errors
Error: Method arguments must be enclosed in parentheses. (line 114)
Error: Name 'xlThick' is not declared. (line 114)
Is their an alternate way to write the Excel commands? Or is there something I need to do in Rhino? Any advice would be appreciated.
Best,
Ben…

H are automated by using them as an ActiveX, the C# script object fails on the simplest tasks. That is, when initiating Rhino and GH externally (as by the following C# code):
Rhino5Application rhino_app = new Rhino5Application();
dynamic grasshopper = newRhino.rhino_app.GetPlugInObject("b45a29b1-4343-4035-989e-044e8580d9cf", "00000000-0000-0000-0000-000000000000") as dynamic;
The following very simple C# script component fails because it cant cast its input:
The c# code at the component is only:
Line 89 is simply casting of the input. Clearly, this makes the usage of C# component, under automation, impossible which is a major loss.
As said, when initiating Rhino and GH manually , all works well as in the following:
Any ideas why it misbehaves under automation (as an Active X ) ?
I added the gh file of this example.…
akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.
