project below- should I be learning Grasshopper & Rhino or just Rhino first?
I'm trying to panel modules with low tolerances- I've prototyped regular shapes like geodesics and am now looking to experiment with irregular shapes with lots of different panel shapes.
I understand some things are best done through Grasshopper when using Paneling Tools- I'm trying to figure out if I can do what I want to achive with PT alone or should do it through Grasshopper (or some other route).
I’m on the MAC WIP - The module was built in Sketchup - all the components seem to be in order as blocks though am having problems running the ptpanel3dcustom command - thinking maybe a bug in the WIP or something wrong with my input or that I imported the sketchup file the wrong way. (I dropped it in the window) - If the 3D command is run it doesn’t do anything - if 2D (ptpanelgridcustom) it crashes.
The tileing pattern - the green rectangle is a refrence. each tile contains 4 blocks with 3 more nested in each.
How the module tiles.
The other thing I'm trying to do is specify that most of the lines in the panels don’t bend/curve when they are paneled (or something like Cage Edited). For my purposes the length & angles can change while the lines must remain straight.
These images show a test tile to be panneled on a ellipsoid. When the tile is mapped to the grid the lines curve, this is an extreme example but notice allot of tiles far from the hemespheres are also bent slightly.
These two questions have me stumped the most for now. What should I look into get a better handle on these problem areas? Maybe I should try recreating the work on a windows machine? or perhaps I should get started with Grasshopper?
Thanks for reading.

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.

ración de 150 horas divididas en cuatro módulos, arrancando el 22 de Marzo del 2011 y terminando la segunda semana de Junio con sesiones los Martes y Jueves de 18:00 a 22:00hrs y algunos Sábados de 10:00 a 14:00hrs.
El tema central del diplomado es el uso integral de la herramienta digital en el proceso de diseño a partir de la base teórica del fenómeno de la emergencia (entendida como la obtención de resultados complejos a partir de la interacción de elementos simples con reglas de bajo nivel de sofisticación).
El desarrollo del programa se concentra en la aplicación práctica de las reflexiones teóricas generadas mediante el uso de herramientas digitales generativas, principalmente Grasshopper (plug-in de modelado parametrico para Rhinoceros).
Contaremos con la presencia de dos colaboradores internacionales: EL primero será un miembro de LaN (Live Architecture Network) que impartirá un curso sobre programación avanzada en Grasshopper enfocandolo a la realización de un objeto construido, haciendo énfasis en la transición entre lo virtual, lo análogo y lo físico. El segundo es Jalal el Ali, maestro en arquitectura por la Architectural Association, líder de la Unidad de Geometría Generativa de Buro Happold y actual líder de proyecto en Zaha Hadid Architects, quien dará un curso intensivo enfocado al uso de la herramienta digital y la producción digital, enseñando procesos que ha aplicado en la empresa donde trabaja. Jalal pronunciará también una conferencia magistral.
Es un programa promueve el uso de nuevas tecnologías y la integración de procesos de producción desde la concepción del diseño, aplicando los conocimientos teóricos en un objeto físico usando el laboratorio de fabricación de la Universidad Iberoamericana.

we're actually using PET sheets for our flexures. We try to design so that the flexures don't go through more than +/- 30 degrees of deflection. If the angular deflection is kept small, the lifetime can definitely be on the order of 1000000 cycles.
As for the design process (item 2), ideally the designer would be able to use a simple 3D CAD tool to design a model of a robot, and the geometry would be represented by dimensioning the individual parts in the model. Maybe there should be some parametric primitive kinematic building blocks like four bar linkages, box frames, etc. that a user could build up a robot from. But, the key functionality the tool needs to provide is for the designer to be able to visualize how the robot will move when it's fabricated. This could mean observing (or plotting) the motion of a leg, a wing, or a series of body segments. Ideally, then, the tool would generate an unfolding of the design. How this would work is still very vague - maybe the user would assist in the unfolding, maybe there would be an optimization routine that computes optimal unfoldings based on criteria like minimal waste, or fewest pieces (I would *not* constrain the problem to construction from a single monolithic piece as in origami). The biggest problem we have right now, is that our design process is totally divorced from fabrication. Even if we went through the trouble of extruding individual thin plates in Solidworks and creating an assembly for visualizing the kinematics of a mechanism, that particular representation doesn't transfer easily to the fabrication process because it's essentially monolithic.
Item 3: The 2D drawing is simple a drawing done manually in Solidworks. There are different layers for flexure cuts, outline cuts, and potentially any cuts to be made in the plastic flexure layer. Depending on the robot, there may be many separate pieces for different parts and linkages in a single robot. For example, the drawing for a robot containing a fourbar linkage may have the linkage laid out as a physically separate piece consisting of five rigid links connected by four flexure hinges. During assembly, the designer would then fold up that linkage and insert it into the robot wherever it's supposed to go. If you're curious you can see some sample 2D drawings for older designs here: http://robotics.eecs.berkeley.edu/~ronf/Prototype/ under the "Example Structures" heading.
I noticed Kangaroo seems to be a popular choice for physical simulations. I don't really even need to include forces like bending resistance - I'm happy to allow the design tool to approximate flexures as pin joint-type hinges. Once the design is unfolded, the details of how to cut the flexures could be worked out in a post-processing step. I wouldn't expect the tool to be able to realistically simulate the bending of the hinges.
I'm going to have to dig a lot deeper into understanding Grasshopper and Kangaroo. I only just got started with Grasshopper today by following the folding plate tutorial on wa11ace.com.au today. …
now.
This V4 can sense if you feed it with your points and uses these instead of the p1,p2,p3 (it's a prelude for V5 that uses DataTrees of points making any surface subdivision a reality). Do the following: sample a triad of your points (NOT internalized) and feed the C# . Then ... start dragging these Rhino points around (the C# responds accordingly). See any difference?
The topology:
Well, the whole fractal logic (in this case) is to have 3 pts on hand (call them p1,p2,p3 : red, green, blue) and then project the "right" one, say, p3 to the Line (p1,p2) > do this > do that ... blah blah.
But ... what p3? that's the 1M question: Here for instance the right p3 (blue) is (by accident) the 3rd point entered (it's obvious the "projection" recursive logic):
but if you drag around a bit the points : p3 is now different (C# does this by sorting synchronously the triangle angles per point VS points) Numbers are used to indicate that "swift" : (0 for the new p1, 1 for the new p2, 2 for the new p3... etc). Compare with the initial points (red = ex p1, green = ex p2 , blue = ex p3).
and again different:
The 1M question:
In fractal thinking the big thing is when to stop: I could obviously control that by a counter ... but here the requirement is the tile min size (within unpredictable amount of recursions) : this is what the stop logic used does.
The 1B question:
So ... implementing fractal logic (against DataTrees of points) to a parametric environment ... requires a lot of questions: because each time the size of the start triad varies ... whilst the stop condition is constant: meaning that with a little bit of "good" luck you can reach incredible high amount of tiles (computer out of memory > Adios Amigos).
Obviously I'm taking having all possibilities in mind and especially big projects > big facades > millions (or zillions) of tiles > Armageddon > ....
more soon

ng in Grasshopper?
As a general recommendation for developers in Grasshopper who are writing a part of their library which is performance-sensitive (please note: often the performance sensitive part is very limited) is to write it in C#, or maybe even C, or maybe even assembly :). Of course, the closer to the machine you will be, the easier it will be to harness all minimal optimizations. However, there is always a compromise between "getting things done" and "making them best" and this boundary is not very easy to catch, right?
If you want to have significant speed improvements for numerical calculations, I would at least recommend developing with C# in a compiled component using Visual Studio or SharpDevelop. The reason is: in order to provide the line number of possible errors, Grasshopper compiles C# scripts in debug mode! They will be much less optimized than what is possible even with today's technology. This does not preclude keeping the project open-source, if that is one of your goals.
Regarding the actual list:
1) Yes, the implied loop will probably be slower than just a simple for loop. This is because Grasshopper code has to keep track of more things than the ones you could be considering with your knowledge of of your very-special case. However, a factor of 10 is simply not acceptable and is likely a symptom of something else. In fact, I think I remember fixing a bug around that in Rhino WIP. However, it appears to be still slower also there. I've added a bugtracking item here.
2) If you are able to do all casts that are involved, and do them as Grasshopper does, please write that code that way. For example, if you supply a curve to an input with number hint, Grasshopper computes the length of the curve. There will have to be an "if" that checks if the input is a curve somewhere (or some similar construct). This aid for designers is what slows down the hint input.
3) Grasshopper has to keep side effects at bay. For example, components B and C are both connected to outputs of A. If you edit data in component B, and that data came from A you of course expect that data to be unchanged in C. This means that, for even lists of numbers, Grasshopper has to perform a deep copy of the output for each input. Otherwise, what happens if B sorts the list and C finds the index of the smallest number? This could be improved if GH components had some way of flagging themselves as non-data-mutating (constant). The fact that, by supplying special types, Grasshopper has no way of performing copies will likely speed things up. But be aware of possibly very annoying side effects creeping in if data is not immutable. Another option is performing the copy "optimally", just where you need it, because you know where your data is used. This is not information that is available to GH at present.
Does this help?
Thanks again for your input,

onents to the latest version and, as you can see, everything works fine:
Over the next week, I am going to be adding in several new capabilities to the Adaptive model in LB+HB that are not an official part of ASHRAE or ISO standards but they are endorsed by the experts and researchers who have helped build the standards. Mostapha, I will be sure to have the component give a comment any time that these un-standardized methods are used and I will be clear that I have made them a part of LB because I have found these insights from new research to be particularly helpful to design processes for passive architecture. Also, I think many of us recognize that both ASHRAE and ISO were initially founded to produce standards for conditioned or refrigerated spaces and that, understandably, they . Among the features that I will be adding in:
1) You will have the option of using either the American ASHRAE adaptive model or the ISO EN-15251 model (see the CBE's comfort tool for a visual of the differences - http://comfort.cbe.berkeley.edu/).
2) In addition to a different comfort polygon, the European standard also uses a "running mean" outdoor temperature instead of the average monthly outdoor temperature. This "running mean" is computed by looking at the average temperatures over the last week and weights each of the daily average temperatures by how recent it is. This makes more sense to me than the ASHRAE method and addresses the issue that you bring up, Alejandro. Needless to say, the updated adaptive model will allow you to use either a running mean or average monthly temperature with either the American or European polygon.
3) The WIP adaptive chart currently has an option for a "levelOfConditioning". This input allows you to make use of research the was conducted along-side the initial development of the adaptive model, which showed that the findings did not contradict the PMV model when people were surveyed in fully conditioned buildings. This parallel research ended up producing a different correlation between the outdoor and desired indoor temperatures and this correlation had a much shallower slope than the official adaptive model for fully naturally-ventilated buildings. The levelOfConditioning allows you to make a custom correlation for full natural ventilation, full conditioning or (presumably) somewhere in between for a mixed-mode building. This levelOfConditioning will become an official input for all LB components using the adaptive model (not just the chart at the moment).
At the end of all of this, I will put together a new video series on Adaptive comfort so that we are all on the same page about how to use the model.
