ents will react to sensors, creating a range of different lighting and spatial effects that will trigger further movement and produce a feedback loop of behaviour and response. To accommodate this responsiveness, the design will be developed using parametric associative modeling, processing, arduino, and digital fabrication using the CNC and Laser Cutters. Students can both develop completely new designs, and/or work on the evolution of the Workshop 1 Supple Pavilion project.
The Visiting School will return to Barracão Escola de Carnaval to evolve the design of the migrating Pavilions, their contents and their context, exploring a design philosophy of interactive event design and the production of a creative fusion of high-tech design generation and fabrication with low-tech redefinition of Carnival-float artisan techniques, paraphernalia, and materials. We will work in the immense and creative Pimpolhos warehouse, collaborating with local artisans of several Samba Schools in the post-industrial, partly-derelict Porto do Rio area, (the birthplace of the Carnival and Samba), introducing digital fabrication techniques. The goal is to create interventions for micro-venues and cultural events that express the identity of the Samba culture within the `Porto Maravilha` planning.
Instruction for the Supple Pavilions workshop series will be led by Rob Stuart-Smith of Kokkugia, Lawrence Friesen of Generative Geometry, Ivan Ivanoff of Interactive Art Estado Lateral Media Lab, Toru Hasegawa of Proxy, with Anne Save de Beaurecueil and Franklin Lee of SUBdV, along with other AA tutors, the Pimpolhos Artistic Directors, and Carnival float-fabricators. Each workshop will provide an introduction to computational design (Grasshopper, Processing and Arduino) and digital fabrication, no previous computational experience is required. Students taking part in multiple workshops will have access to advanced computation instruction. This workshop will produce 1:1 prototyping, exploring the structure and transformations of the pavilions. Final fabrication and assemblage will occur in July.
The workshop is open to architecture and design students and professionals worldwide. Participants can take part in one or more workshops, with fee discounts offered to those interested in multiple workshops.

dy for a wall where we want to analyze its openings. I made a parametric wall that then get's analyzed with different geometries and the idea was just to leave it there for the weekend as it morphed through different iterations. However, after successfully running a test simulation on my pc (just with one iteration), it fails to run the same test on the workplace computer. Any help would be greatly apprecated! Here is the following error:
Sorry! But the number of available CPUs on your machine is 4.
Honeybee set the number of CPUs to 4.

The component is checking ad, as, ar and aa values. This is just to make sure that the results are accurate enough.

answer further on Friday.
The "ghdoc" variable and rhinoscriptsyntaxThe ghdoc variable is provided by the component if you select it as "target".You might ask yourself: "why do we need it"?Its use comes from the very design of the established RhinoScript library. This library is imperative, which means it is build from a set of procedures or functions that act on various geometrical types. Additionally, there is one level of indirection: most of the time, the user does not work with the geometry itself in the variable, but rather with Guid of geometry that is present in a document. This is exactly what ghdoc is: it is the document that the RhinoScript library always implicitly targets with all AddSomething() calls (for example, AddLine()).
Based on this comment...RhinoScript use within GhPython may be less idealThat comment is from a previous version of this component that did not have the ghdoc yet.With the ghdoc variable, the standard Rhino document target of RhinoScript is replaced, therefore we can use Grasshopper while leaving the Rhino document unchanged. This saves uncountable Undo's, and makes it easy to structure ideas through the definition graph
...is the rhinoscriptsyntax target irrelevant if using solely RhinoCommon classesYes. If you create class instances (objects), you will need to create also your own collection objects to store them (mostly lists, trees). You can imagine the ghdoc as being an alternative to them, just that you do not access data by index (number), but by Guid. So you can use the RhinoScript or the RhinoCommon libraries independently or mix them. The RhinoScript implementation in Rhino is open-source and is all written in RhinoCommon. Also the ghdoc implementation is open-source, and is here.
RhinoScript and/or RhinoCommon objects which are not recognized as valid Grasshopper geometryYes, sure, Grasshopper handles only a portion of all available types. Basically, unhandled types are all the types that do not exists in the 'Params' tab. For example, there is no textdot and no leader, so on line 149 there is a throw statement and all TextDot calls (about line 350) are commented out. When/if Grasshopper one day will support these types, these calls will be implemented.
DataTreeHere is a small sample. However, I think that 80% of the times it is not necessary to program for DataTrees, as the logic itself can be applied per-list and Grasshopper handles list-iteration.
I hope this helps,

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,
Ding

ay how many valid permutations exist.
But allow me to guesstimate a number for 20 components (no more, no less). Here are my starting assumptions:
Let's say the average input and output parameter count of any component is 2. So we have 20 components, each with 2 inputs and 2 outputs.
There are roughly 35 types of parameter, so the odds of connecting two parameters at random that have the same type are roughly 3%. However there are many conversions defined and often you want a parameter of type A to seed a parameter of type B. So let's say that 10% of random connections are in fact valid. (This assumption ignores the obvious fact that certain parameters (number, point, vector) are far more common than others, so the odds of connecting identical types are actually much higher than 3%)
Now even when data can be shared between two parameters, that doesn't mean that hooking them up will result in a valid operation (let's ignore for the time being that the far majority of combinations that are valid are also bullshit). So let's say that even when we manage to pick two parameters that can communicate, the odds of us ending up with a valid component combo are still only 1 in 2.
We will limit ourselves to only single connections between parameters. At no point will a single parameter seed more than one recipient and at no point will any parameter have more than one source. We do allow for parameters which do not share or receive data.
So let's start by creating the total number of permutations that are possible simply by positioning all 20 components from left to right. This is important because we're not allowed to make wires go from right to left. The left most component can be any one of 20. So we have 20 possible permutations for the first one. Then for each of those we have 19 options to fill the second-left-most slot. 20×19×18×17×...×3×2×1 = 20! ~2.5×1018.
We can now start drawing wires from the output of component #1 to the inputs of any of the other components. We can choose to share no outputs, output #1, output #2 or both with any of the downstream components (19 of them, with two inputs each). That's 2×(19×2) + (19×2)×(19×2-1) ~ 1500 possible connections we can make for the outputs of the first component. The second component is very similar, but it only has 18 possible targets and some of the inputs will already have been used. So now we have 2×(18×2-1) + (18×2-1)×(18×2-1) ~1300. If we very roughly (not to mention very incorrectly, but I'm too tired to do the math properly) extrapolate to the other 18 components where the number of possible connections decreases in a similar fashion thoughout, we end up with a total number of 1500×1300×1140×1007×891×789×697×...×83×51×24×1 which is roughly 6.5×1050. However note that only 10% of these wires connect compatible parameters and only 50% of those will connect compatible components. So the number of valid connections we can make is roughly 3×1049.
All we have to do now is multiply the total number of valid connection per permutation with the total number of possible permutations; 20! × 3×1049 which comes to 7×1067 or 72 unvigintillion as Wolfram|Alpha tells me.
Impressive as these numbers sound, remember that by far the most of these permutations result in utter nonsense. Nonsense that produces a result, but not a meaningful one.
EDIT: This computation is way off, see this response for an improved estimate.

te some cut sheets, but not to optmize material, rather define some cut lines. Everything that I am cutting is made of planar wood elements, but there are very specific geometries (mostly straight lines) and I have to put tolerances and radiasas at the corners in order to cut on the cnc mill. Spending time to figure out how to automate is necessary, but I am stuck!
One thing the definition is doing is taking my brep modeled components in rhino and makking them into 2d close curves and laying them side by side. It works...not ideal as its not layed out in a sheet, but that is not the most important part.
Another particular problem is that you will see some notches in the curves, which other pieces will slip into, so different slots need different specific offsets (making them larger) as a toelrance to allow for material play. This I don't even know how to set up so maybe it will just have to wait.
THE MAIN QUESTION, and super important would be, LIFESAVER:
At all 'inward' corners...which I think will always mean concave corners (most are 90 degrees, but are within to sides, instead of a corner sticking out). I'm sure its obviousy, but the reason being the outward corners a circular dril bit can cut, but inward ones need an arc profile extended beyond where the corner of the other piece will fit into. The drill bit i am using is 6mm, so 6mm diamters arcs is what i'm working with.
I have managed to put such an arc at every vertices of each cut piece. The problem being some stick outward isntead of cutting into the piece. So each one needs to be orieneted correctly. Ideally they would also only draw into inward corners, but I can always delete them out. I think maybe I am missing a more logical mathematical way of defining?
For these geometries it is not very important which side the half circle arc in on in the inward corners, but I also have some geometries that I will have to control where the circles face according to the rest of the cut piece.
The cutouts in the middle of the pieces that are curves do not need such corners obviously.
The picture is an example drawn
I hope this isn't too specific and long. in general though automating fabrication, and controling pracitcal math and orientation problems like this is itnersting to me!

perienced with grasshopper, but so far I've managed to combine the following:
Giulio Piacentino's "Catenary arch from height" script
Pirouz Nourian's "Mobius" script (Obtained from a friend)
End Result:
Here's where I'm stuck: I want the mobius twist to revolve around the midpoint of the arch, but the script uses the input values to determine the endpoints, resulting in a weird sinuous shape when viewed from above. Also, the secondary end points (generated by the mobius script, determining the width of the surface) are generated by default along the z axis, resulting in an arch that only touches the "ground" at two points. I attempted to work around this issue by trying to force the zHeight parameter to correspond with the y axis (thus rotating the arch 90 degrees so it would lay "flat"), but the script interprets the third point as a value and not as an actual point to bisect. I thought this might be an issue with the C# component that I obtained from Giulio Piacentino's script, so I attempted to tinker around with the source code. Unfortunately, I'm not fluent in C# so I only managed to mess everything up (I've since recovered the code from the cache). Anybody got some ideas? -BC …
onsidered period.
Even if the end of July for the mediterranean climate is not the best period to perform an adaptive comfort analysis (it's just a pretest to define a LB model) I want to refine the Adaptive comfort Chart (AC) by changing the external air temperature data imported from the .epw file with that of monitored data as reported here below:
Where the monitored ext air temperature are in this form (green panel below):
I have used the comfortPar component to set the following parameters:
Adaptive chart as defined by EN 15251
90% of occupants comfortable
the prevailing outdoor temperature from a weighted running mean of the last week
fully conditioned space (even if it is not properly in line with AC as already discussed)
The question is this: the AC component could correctly apply the code below if there is only a list of external temperature data for a restricted period (without indication about the limits of this period) and not for an entire year?
else: #Calculate a running mean temperature. alpha = 0.8 divisor = 1 + alpha + math.pow(alpha,2) + math.pow(alpha,3) + math.pow(alpha,4) + math.pow(alpha,5) dividend = (sum(_prevailingOutdoorTemp[-24:-1] + [_prevailingOutdoorTemp[-1]])/24) + (alpha*(sum(_prevailingOutdoorTemp[-48:-24])/24)) + (math.pow(alpha,2)*(sum(_prevailingOutdoorTemp[-72:-48])/24)) + (math.pow(alpha,3)*(sum(_prevailingOutdoorTemp[-96:-72])/24)) + (math.pow(alpha,4)*(sum(_prevailingOutdoorTemp[-120:-96])/24)) + (math.pow(alpha,5)*(sum(_prevailingOutdoorTemp[-144:-120])/24)) startingTemp = dividend/divisor if startingTemp < 10: coldTimes.append(0) outdoorTemp = _prevailingOutdoorTemp[7:] startingMean = sum(outdoorTemp[:24])/24 dailyRunMeans = [startingTemp] dailyMeans = [startingMean] prevailTemp.extend(duplicateData([startingTemp], 24)) startHour = 24
