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.…
ard to find example...
I do not know how to load windows form and send data to object in form.vb...using grasshopper sdk.
it is the same,, when I try to use dll(class) with VB component in grasshopper.
may be I have to make two class (class1, form1) but,
when I send data to class1, form1 can not receive class1 data because form 1 made new class1 and both class1, class1(from form1) is different session?
for novice programer,, for me it is very hard.
load class1,
class1 load form1
send data from grasshopper to form1. x
and button click
couldn't calculated,... result was always "0"
and tried many other methods,, but it failed...
may be some known technic but it is hard to find books...
Please...help me.
if possible would you tell me how to load form1 using grasshopper sdk and ""send data "" to form1
or form1 could use data from grasshopper?
Thank you....
for ex)
'(in class.vb)
Public Class Class1 Private Shared fl As Form1 Public Sub fload() If fl Is Nothing Then fl = New Form1 fl.Show() End If End SubEnd Class
'(in form1.vb)
Public Class Form1 Public x, y As Double Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ab(x, y) MsgBox("hi" & y) End Sub Sub ab(ByRef a As Double, ByRef b As Double) b = a * 2 End SubEnd Class
'(in Grasshopper VB.component)
Dim cl As ClassLibrary1.Class1 If cl Is Nothing And f = True Then cl = New Class1 cl.fload() End If Dim fr As ClassLibrary1.Form1 If fr Is Nothing Then fr = New Form1 End If fr.x = x a = fr.y…
f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

he concept, moving on to decision making and continuing with digital and generative design tools TO GET THE BEST SOLUTION for each problem.
WHY? The world is complex and ever-changing and we need to be able to handle the volume of information we receive and, of course, to find and choose the best solution. Therefore, we direct our ATTENTION TO THE CAUSE, and not only on the effects/solutions.
We will learn from NATURE, the only “company” that has not gone bankrupt in over 4000M years, and it’s GENERATIVE SOLUTIONS.
> OBJECTIVES <
The participants will work in multidisciplinary groups (ex. architect + designer + business manager + constructor + communication specialist etc.) applying knowledge management tools, different approaches and nature-based optimization methods.
Listed objectives:
1. Improving the generative way of TURNING AN IDEA INTO A PROJECT through problem-solving thinking
2. Discovering nature’s ways of shaping evolutionary solutions
3. Getting out from our comfort zone and working together with other professionals in groups in order to achieve better solutions: Multidisciplinary Design Optimization
4. Learning to use technology to manage information in the decision making process

er, i hae drawn a quck sketch. Different curves in blue and orange colour. i have marked on my sketch which is a a non-planar surface.
At the moment, i have modeled this with NURBS curve component (component without Knots & Weights). I have set 5 to its 'P' intput (I'm going to reduce it to 3). Each point having 3 parameters X, Y & X axis. I have set my slider from -100mm to 100mm range. It is a closed curve.
If i just loft it, i get random results which i donot want. I can get a planar surface if i set Z parameter to zero. But how do i get a non planar and preferably a burbs surface?
the curves are very important to this projects. as Whole form is dependent on these curves.
Your tips will be highly appreciated. If you have different way of modelling it, I'm open to suggestion too.
cheers,

and perpframes
3) Ellipse on perframes
4) Series + Move + Series + Scale + Series + rotate (to create generations)
5) Divide curve (ellipse) + Dispatch only seleced points + join those points on ellipse using Intercurve + Divide the resulting intercurve
6) List items (I used list items 4 times, you could do as many). For 'i' parameter in list item i used slider to create generations. depending upon your definition, at this stage you might have to flatten your list output
7) joint the points you get from list output to form another intercurve + repeat that for all items.
8) Loft the curve
9) to form fenestrations, i again used rhino closed curves.
8) Project curve onto surface + copy trim + surface to mesh + mesh thickening from WB.
Hope this helps
Cheers

his project. Attached is my latest script. It seems to work for all points & directions of gravity except when the points are at equal height (in the reference plane the script creates, not in the world space). In other words, when the vector from A to B is perpendicular to the gravity vector, it doesn't work. It's totally due to the formulas used to solve for distance (see script), but I haven't found a way to fix it to make it work. Kudos to anyone that can help me figure it out!
Other notes: Required input: Point A, Point B, Gravity vector, and desired Height and/or desired chain/arch Length. Cool trick: when inputting both Height and Length, it recalculates the end point (point B) with those desired parameters, and the end point lies along the AB vector. Also, the "x" output shows either the found height, length, or distance (when both height & length are input), and "newPl" just shows the reference plane used to make calculations easier.
