r (top left) is connected with the list which contains the centroids of every triangle of my mesh (my canopy, that I turned into a series of triangular surfaces). In this part of the definition I evaluate the Z coordinates (extracted form the points).
I execute some operations in order to have my values from 0 to 1 (parametrization). Then I sutracted the lower value of the list to all the data. So I obtained a new list of numbers, which stay from 0 to 1 and I can use in order to determine a gradient in the arch openings.
The result? If you look carefully to the rendering I posted you'll see that the arches are less opened near the ground and more opened near the top. It's a structural way of design the canopy. The more loads you must support, the more closed your arches will be (and the more stronger you should be).
Anyway consider this part as not important, because this parameter is just a my interpretation, it's not essential in order to obtain the canopy I posted. If you want you can just substitute that emitter with a simple number, from 0 to 1. Don't know, try to put 0.4 as an imput and let's see what happens. The result will be more similar. ;-)
Nice to meet you Morgan.…

"This is a preview of a parametric conceptual design tool for architectural
practice that I have been developing at NBBJ. I wanted to develop a
system that allows designers to quickly organize and understand complex
architectural programmes in three dimensions.
It is an advancement of the traditional bubble diagram; it solves
adjacency requirements automatically and suggests planimetric and
sectional relationships. The resulting diagrams are not formal
solutions; they are simply organizational diagrams with solved
adjacencies and accurate required areas. The diagrams are raw
materials, meant to be manipulated sculpturally, or even squeezed into a
formal container.
Technical Information
The tool was created in the Grasshopper plug-in for Rhino. Custom components, written in VB.NET,
read programme data directly from Excel into Grasshopper. The tool
uses the Kangaroo engine for realtime spring dynamics simulation."

green & B in red. These surfaces are at the centerlines of thicker beams in the model (not shown).
I have a list of "Intersections", the yellow vertical lines, usually four at each point the beams intersect (85 points or 340 intersections expected, though there are only 335).
What I'm trying to do is "get" the list of yellow vertical lines for each beam and keep them "associated", so that I can re-orient them with the thick beams in a flat, "nested" layout.
These intersections will appear in two sets of lists, one for beams "A" and another for beams "B".
I found and hacked a bit of C# script to partition the sorted list of indexes but not the related list of intersections ("Line-like Curves").
In this case, the data trees aren't working for me. I want "beam objects" with arbitrary properties, such as lists of intersections. Are there ways to do this "easily" in GH without resorting to C#, VB or Python?…

2. This actually means that the parts on duty they don't differ that much. Meaning that we can use an "average" size (and "local" topology) acting as the Jack for all trades.
3. Meaning that we can effectively solve the abstract topology with an abstract app the likes of GH and then place in properly defined coordinate systems all the real-life bits and nuts ... closely "emulating" a pro solution (that could "adjust" the parts as well).
4. This means that one particular C# needs more lines of code since as it is it defines cable axis on a per nod to node basis ... but in fact these are defined as the min segment between curves (circles to be exact).
5. Additionally the end part of each strut differs depending on how many pairs of stabilizing cables are used (either 2 or 1). Meaning some lines of code more for defining the proper coordinate systems for the instance definitions.
6. This is the reason that I've postponed mailing to you the 4 horsemen (because PRIOR finishing the whole you MUST define what parts to use: the classic bottom-top design approach).
But in order to receive the Salvation (aka: Apocalypse) you MUST answer correctly to a simple puzzle:

orking in Grasshoper v0.9.00xx (I tried, 9.0010 and 9.0014)
If I try this code
------------------------------------------------------------------------------
System.Globalization.CultureInfo oldCI = new System.Globalization.CultureInfo("en-US");
Object objExcel;
objExcel = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application");
objExcel.Cells(2, 1).Value = "titleA";
------------------------------------------------------------------------------
I see, the message
" Error: 'object' does not contain a definition for 'Worksheets' (line 95) "
Line 95 is the last one < objExcel.Cells(2, 1).Value = "titleA"; >
I've also tried,
Microsoft.Office.Interop.Excel.Application xlApp;xlApp = (Microsoft.Office.Interop.Excel.Application) System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application");
But GH C# says
Error: The type or namespace name 'Office' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?) (line 89)
What did I wrong??

obably only using Rhino4, but three people who bought Rhino2, Rhino3 and Rhino4 respectively are three people using one version each.
We certainly don't know how many Grasshopper users there are. Grasshopper installers are not always downloaded via our website or -once downloaded- used multiple times (think class-rooms and company IT). We have no way of knowing whether someone who once downloaded Grasshopper is still using it. That being said, Grasshopper is downloaded ~100 times a day from our website and this number has been fairly constant since 2009 (though slightly on the increase, I'd say ~80 a day in early 2009). There are nearly 96,000 unique email addresses in the Grasshopper mailing list, more than 455,000 in the Rhino4 mailing list.
The size of this community (>17,000 registered users) is a much better indicator of user-base magnitude, but even here we have no idea how many people registered but are now no longer using GH as we do not collect use statistics (yet).

What I figured yesterday is that the increase in radiation because of the reflective facade for the 'worst' month is only about 2-3 kWh/m2 as your looking at a value of 80 without and 82-83 kWh/m2 with reflection.
So my assumption is that the glare factor will play a much bigger role instead of intensity of the sun, looking at comfortable levels. So I'm looking in this as well. It's very cool to play around with these plugins and see the outcome. I'll keep you guys posted.
@ Claudio, that was exactly my problem as well. I presented a direct sunlight hour analysis, to show the increase in direct sunlight hours because of the mirrored facade and at what times of the day the reflections occurred. But it is hard to asses if this is 'bad' or 'good'. The restaurant in question receives more or less 130 direct sunlight hours 'naturally' in the worst month and because of the reflection the result was 161 direct sunlight hours, but the client was like okay..... and is this a problem? So we decided to look at sun intensity but I didn't want to fall into the trap of in the end presenting kWh/m2 and having the same problem not knowing if this is 'comfortable' or 'annoying' etc. Good luck with your study, I'll post my findings
Thanks again guys…

I think i'm about 80% there. It may not be the most elegant procedure, but it appears to be working. I am having some slight problems.
1. I'm having trouble extracting the edge curve on one side of my mesh
a. I used a mesh plane intersection to trim my site mesh, and the resultant curve extends beyond the limit of my mesh
b. I identified the intersection point, but GH is not shattering on that intersection point. instead it happens at a point further down the polyline
2. I'm can't join my curves. If i bake them, they join into a closed curve.... GH join curves is not behaving. i've had some success joining two segments, but i can seem to get all 4 side wall curves to join.
if anybody could offer some advice, i'd be very appreciative. also, i'd like some recommendations for ways to streamline this definition. I'm sure that there are more creative ways to manage this data, and i'd love to about them. thanks - CSDG

use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
