ive input but I have no clue how to begin doing this. I've read about using Processing and have even tried something with Processing but it didn't work for me.
I haven't had any luck finding step by step tutorials on inputing data with the 'read file' tool either. I have a feeling that just knowing how to import data would help a lot but the only examples I've found didn't work for me.
I'll be honest though, when it comes to programming and code, I'm an idiot and at a very beginner level. However, once I have working code to study and play around with, I pick up pretty quickly. I've done this with some of the GH definitions I've found and had some good results.
Basically, it's been very difficult and frustrating since I've spend literally 4 weeks trying to figure this out. Like I said, I'm not good with code! Fortunately I've had a little bit of help from the GH community and am very thankful. With any luck, maybe some other people on here would be willing to help out a couple students working on a thesis project? We don't have money but could exchange fabrication services for your help with code or definitions. We have access to a 3 axis CNC mill, Laser Cutter and FDM printer.
Thanks for your time (and hopefully your help),
Matt.

to problems. If anyone wants to take a look at the attached file "605b-3" and try to help me, that would be awesome.
The way I'm thinking about creating the louvers:
1. Contour the shape (could be any shape, but I attached the one I'm trying to do it to)
2. Divide those contour curves
3. Find the 4 points on those curves that are furthest away from the center of each curve
4. Move those points slightly away from the center of each curve
5. Replace the unmoved points with the moved points
6. Interpolate/NURBS curve through the new list of points
7. Loft the new curves with the original contour curves
I think I'm close, but I'm getting stuck at the end- I thought shifting lists would be the best way to solve my problem, but I'm a little confused as to how grasshopper is organizing the list of new curves and how to match that organization to the original curves.
Attached is an image of where I am stuck. I can only create a surface in the gap that I'm trying to create by the louvers. Either that, or one or two of the curves tends to create a "tornado" looking thing and i can't figure out how to fix it without individually breaking up the list. Is there a way to set all the curve seams to be at the same location in a list?…
ry branches would be an added bonus.)
I had an idea of using contours to find the center point, then connecting these found center points to create my centerline. However, I am facing a few challenges... specifically, I do not know how deal with splits in the tree branch.
I think I have an idea for how to deal with this, but I am not skilled enough (yet) to execute. The whole idea would look like this:
1) create a list of contours through the tree branch
2) connect the center points of the contour lines
3) when a single contour produces two separate polylines (when the tree splits), AND the previous contour produces only a single polyline, divide the list into two new lists starting at that contour.
4)when a single contour produces two separate polylines, AND the previous contour also produces two separate polylines, draw a polyline between the closest pair of centroids.
Has anyone run into this (or something similar) before? And, is this a good way of going about it?
The attached script is incomplete, but has the oak tree branch internalized.
I have been struggling hard with this....Any help would be greatly appreciated!!
Thanks,
Ethan

2. WORKSHOP (23-27 April 2014)
A 5 day Design-Based Research Workshop exploring new techniques in Digital Architecture/Fabrication, with a specific focus on the use of generative systems and parametric modeling as tools for creative expression.
Our ultimate goal is to increasing the efficiency of utilizing digital tools in parallel with geometric performance of the primitive design agent.
+ + CONCEPT
Fashion and Architecture are both based on basic life necessities – clothing and shelter.
However, they are also forms of self-expression – for both creators and consumers.
Both fashion and architecture affect our emotional being in many ways.
The agenda of this workshop is to investigate on the overlap between these two areas of design, art & fashion.
Fashion and architecture express ideas of personal, social and cultural identity, reflecting the concerns of the user and the ambition of the age. Their relationship is a symbiotic one and throughout history, clothing and buildings have echoed each other in form and appearance. This only seems natural as they not only share the primary function of providing shelter and protection for the body, but also because they both create space and volume out of flat, two-dimensional materials.
While they have much in common, they are also intrinsically different – address the human scale, but the proportions, sizes and shapes differ enormously.
+ + + OBJECTIVES
So far, Architects have been using techniques such as folding, bending etc. to create space, structural roofs or different other structural shapes.
The agenda of this workshop goes further with the investigation of algorithmic thinking through generative tools Integrated in design.
The challenge is creating a bridge that connects these two areas of design, architecture and fashion that perform at two opposite scales.
+ + + + TECHNICAL BRIEF
In the early stages physical models and low-tech strategies will be used, allowing the participants to gain a greater understanding of materials, fabrication and assembly methods as well as simple, yet pragmatic structural solutions.
Later in the workshop these strategies will be digitalized and elaborated using software visualizing tools such as Rhinoceros and the algorithmic plug-in Grasshopper.…

Descriptions
Ladybug + Honeybee
Ladybug and Honeybee are open source environmental plugins for Grasshopper that help architects and engineers create an environmentally-conscious architectural design.
Ladybug imports standard EnergyPlus Weather files (.EPW) into Grasshopper and provides a variety of 3D interactive graphics to support the decision-making process during the initial stages of design. The plugin also provides further support for designers as they test their initial design options with radiation, sunlight-hour, and shading analyses. Integration with Grasshopper allows for an almost instantaneous feedback and, since the plugin runs within the design environment, the information and analyses are interactive.
Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and OpenStudio for building energy and daylighting simulation. The Honeybee project intends to make many of the features of these simulation tools available in a parametric way. Just as users have made changes to geometry for years in Grasshopper, now users can parameterize system types, zoning schemes, schedules of operation, daylight sensor placement and controls - all of the “hardcore” simulation parameters that have never been exposed to parametric modeling tools.

step-sizes. It starts out with large jumps, then as it cools the jumps get smaller and smaller as does the likelihood of a retrograde jump being accepted as a valid new state.
Most fitness landscapes have more than one dimension and therefore a 'jump' could include any number between 1 and N, where N is the dimensionality of the landscape. The Drift Rate setting —which may well be poorly named— controls the odds that a jump includes an additional dimension. All jumps must be at least one-dimensional, but 25 percent of them (on average) will include another dimension. 25% of those will include a third dimension and 25 percent of those a fourth and so on and so forth until the dimensionality of the landscape has been reached. Here's a list for 1000 jumps:
Drift Rate: 25%
1D jumps: 750
2D jumps: 187
3D jumps: 47
4D jumps: 12
5D jumps: 3
6D jumps: 1
A good question to ask would be; "Why would you want a jump to include more than one dimension?" and the answer is that the more genes are related, the higher the changes that a multi-dimensional jump will yield an improvement. It's not difficult to imagine that you cannot improve your current state by only modifying a single gene. Sometimes you need to change two in unison in order to reach a better solution. If your genes are highly related (which is bad practice to begin with) then you may need to adjust the Drift Rate to a higher value.

make sure I add this information to groundTerrain_ inputs in the next few days.
So if you are using "Gismo Terrain Generator" component (former "Ladybug Terrain Generator 2" component), only the following types are allowed for groundTerrain_ input: type_ = 2 (surface with rectangular edges)
type_ = 3 (surface with circular edges)If you are using "Ladybug Terrain Generator" component, then only the:
type_ = 1 (surface with rectangular edges)
is allowed.
As for terrain not being colored when it is created as a surface, you can analyse it additionally with "Terrain Analysis" component for Elevation analysis type. It can even be colored for rendering afterwards by using the "OSM Render Mesh" component. Check the attached file below.Have in mind that in urban areas "Ladybug Terrain Generator" component produces much more precise terrain than "Gismo Terrain Generator" component. On the other hand, the latter component can generate much larger terrain areas (up to 10 000 sq km2, at least in theory).
The reason why component might still work even though a terrain mesh has been added to the groundTerrain_ input is probably because once groundTerrain_ input fails to convert a mesh to a brep, this results in it being equal to None. Component then considers as if groundTerrain_ input is empty and runs as if nothing has been added to it (the buildings are laid down on a flat plane with 0,0,0 as the plane origin).
Thank you once again for all the testing you are doing!!! It really makes Gismo a better plugin!!…

ng the "kaleidocycle" as a facade component, and i need to be able to move it through its entire "rotation" in 3d space to understand where and how it is moving.
http://www.youtube.com/watch?v=4owFczeqqMQ
this is what it is doing, in general. there are 2 sets of 3 hinges, rotated 180 degrees, making up a hexagonal form.
here is a rhino model of the form. i used the trigonometric properties of the isoceles triangle to make this model very accurate (63.333, 53.333, 63.333 angles), and now i need to describe the movement.
It is TOUGH. i think i have it and it just throws me for a loop (no pun intended).
I have a ghx model set up to where it can go through part of the cycle, but the inbetween states are incorrect, and therefore it's not valid, but it shows how something like this could work. The trick is it rotates on multiple axes at different times, and its just very very tricky to figure out what it is rotating around and when.
If anyone has any ideas, or insight, please please let me know. I am working on this in my masters' studies, and I'm pretty screwed if i can't figure this out in grasshopper!
Also, please find attached a research article concerning this form. I haven't been able to apply the geometric findings of theirs, yet. But it shows it can be described mathematically.
THANK YOU!!!!

ts connectors and slots that allow CNC machining the facets and connectors for assembly.
https://www.youtube.com/watch?v=34OvgflJEmI
We developed this construction methodology earlier this year while working on a large scale parametric structure for Midburn, the Israeli Burning Man. While doing so I used grasshopper to generate the facets for the geometry, while a friend on the team (Matan Zohar) wrote a javascript app that translated the mesh into connectors and slots for CNC manufacturing. You can see more about the project here:
http://www.shlomimir.com/triped/
I wrote this component as an exercise in learning rhinoscript and python, with the purpose of bringing the functionality into the grasshopper workflow. It's now to the point where it is working for triangle and square welded meshes while outputting the connectors and slots as an unorganized list.
Questions and To Do List
1. I'm new to object oriented coding and functions, and basically just wrote the whole thing as a series of conditional loops with two dimensional arrays holding the data. Planning on restructuring this better, would love any tips.
2. Right now outputting the connectors and slots on the input mesh itself in 3D, planning on setting this up layed out on one plane to organize for cutting. I was wondering if there are any existing tools for this or if I need to do this manually.
3. Labeling connectors and slots. Is there anyway to output text from python that can be later baked into the rhino for labeling?…
