iece could be easily cut using the "plan" curve, the wall need extra attention and manual work to prepare.
This script attempts to automate the preparation of lasercutting curves with some control:
1) Height: The parameter is set using the "Name" property of the Rhino "plan" curve object. Number of storeys (e.g. 5) is to be entered in that field and the script will read it after you press F5 (recompute) in grasshopper. If the block models are not multiples of standardised storey height, you could set "Storey height" in grasshopper to 1 and set exact height to individual "plan" curves in Rhino.
(Special mention: This part of script including reading "Name" property in Rhino and auto-correcting curve direction is attributed to Victor Leung's Laser Cutting Tool for Block Models)
2) Mode of wrapping: The wall could either be "sitting" on the bottom plate and being completely covered by the top plate, or wrapping outside both the bottom and top plate. In either case, material thickness is taken into consideration and the finished model will remain the same size.
3) Extra height option: In preparing flat roof models, one may like to add extra height for parapet wall to make the model more appealing.
4) Easy picking up: Each individual piece has some uncut part (red lines for engrave) to hold itself in place after cutting. There is no need to use masking tape to stick. Individual pieces could be taken out when you are ready to use.
There are also known issues to this script:
1) At internal corners, the adjacent wall will be longer (in wrapping outside mode) or shorter (in sitting inside mode). You have to manual cut at this point.
2) It could not work with only one input curve. (Although it may be a stupid bug,) A dummy rectangle nearby could be created to make it work.
Enjoy,

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.

hat offer an even spacing of 11 gems from 0.0 to 1.0, and though the Anenome script works it is not as robust to various shapes and sometimes just stops at some point even on mellow curves:
The Hoopsnake script in the other thread: Hoopsnake doesn't want to appear multiple times in a document since resetting one resets them all and it only runs the first instance when I pasted two more copies of the whole script in, so I'll do them separately, and instead of an input reset wire, there is a right click Reset All item in the pop-up menu.
I understand now how the two looping components work, in having a geometry input for the first item, then they accept a second item input as new geometry that then gets looped as the new geometry replaces the original. What a great hack, so I was wrong above about only being able to loop numerical values.
Since I really like Anenome better due to its nice interface, I've converted the old thread Hoopsnake program to Anenome. It still won't handle multiple curve pairs, so I made copies of the whole script.
I learned a lot today. Thanks guys. Given how well these straightforward scripts can work, I'll bet there's a much shorter Python version possible, one that most anybody could understand and thus adapt. If I have time I can start again this time from scratch. Converting the long one taught me about the problem though. Grasshopper makes it easier though, since Circle TTT only needs one center point hint whereas Rhinocommon TryFitCircleTTT needs three.…

h is attached below. it`s an arch, let`s say out of bricks with loads, represented with point loads which are taken from user-defined surfaces (to represent self-wight e.g).
goal of the study is to find a supporting arch which is inside the arch then (provided the strength of the bricks is high enough) the arch is ok -otherwise one have to change the geometry of the arch (make it thicker, or change the rise of the crown).
therefore i used kangaroo in combination with galapagos to find a catenary which fulfill the boundary conditions. it works very well. so the solution galapagos found is very satisfying.
it`s simple to prove the resulting forces in the arch if one knows the rise of the arch.
according to the formula N~ q*l^2/(8*f)
with q= 21 kn/m, l= 10.00 m and f= 0.965
one get N= 272 kn, which is very near on the solution which kangaroo founds in the middle of the arch (271 kn). due to the point loads this force have to get slightly higher the nearer one comes to the anchor points. this works perfect too.
but there is one irritating thing.
at the end of the catenary, near the anchor points, kangaroo gets two very different arch-forces. 281 kn in the next to last part. and 581 kn in the very last part. this is not possible and i am sure that the value of 581 kn is wrong. i calculated the example with a commercial fea-program too. it validates the kangaroo results except the first and the last one.
i think there is a problem with the calculated end length of the first (and last) element. they are twice too long as they have to be. or do i something wrong?
thank you for any reply and again for your work.
best peter

. From the Thermal Comfort Indices component, Comfort Index 11 (TCI-11):MRT = f(Ta, Tground, Rprim, e)
with:- Ta = DryBulbTemperature coming from ImportEPW component- Tground = f(Ta, N) where N comes from totalSkyCover input. Tground influences the long-wave radiation emitted by the ground in the MRT calculation.- Rprim defined as solar radiation absorbed by nude man = f(Kglob, hS1, ac)- ac is the clothingAlbedo in % (bodyCharacteristics input)- I can't find any definition in the code of Kglob and hS1. Could you tell me please what are those values referencered to? --> probably the globalHorizontalRadiation but how?- e = vapour pressure calculated from Ta and Relative Humidity input
Do you agree that in this case the MRT does not depend on these inputs: location, meanRadiantTemperature, dewPointTemperature and wind speed?It does not depend neither on the other bodyCharacteristics like bodyPosture, age, sex, met, activityDuration...?
MRT calculated by the TCI-11 method is the mean radiant temperature of a vector pointing vertically with a sky view factor of 100%?For ParisOrly epw,
2. From the SolarAdjustedTemperature component (that seems to be more used for the UTCI calculation examples on Hydra compared to TCI-11).
In contrast to the TCI-11, this component distinguishes diffuse and direct radiation and contextualizes the calculation thanks to _ContextShading input, right? It can also be applied to a mannequin thanks to the CumSkyMatrix and thus evaluate the dishomogeneity of radiation exposure.This component seems not to consider the influence of vapour pressure on the result --> is it then more precise to put the MRT output (from the TCI) as an input of meanRadTemperature for SolarAdjustedTemperature?The default groundReflectivity is set to 0.25 --> is GroundReflectivity taken into account in the Tground or MRT calculation in the TCI component? If yes, what is the hypothesised groundReflectivity?The default clothing albedo of 37% (TCI-11 bodyCharacteristics) corresponds to Clothing Absorptivity of 63%?
If the CumSkyMatrix input is not supplied, I get 9 results for the mannequin --> where are those points/results coming from?
If the CumSkyMatrix input is supplied,I suppose the calculation of the 482 results correspond to a calculation method similar to the radiation analysis component that is averaged over the analysis period. Right?But I don't understand why the mannequin is composed of 481 faces and meshFaceResult gives 482 results.
Finally, what is the link between the MESH results, the solarAdjustedMRT and the Effective Radiant field ? Is there a paper to have a detailed explanation of the method?
3. Here are some results for the ParisOrly energyplus weather data. You can find here attached the grasshopper definition.There is no shading in this simulation and the result coming from the ThermalComfort indices for MRT is very different compared to the solar adjusted MRT.Why such a big difference and which of the result should be plugged into the UTCI calculation component?

sinergetici associati alla compresenza simultanea di differenti strumenti di analisi e digital design all'interno di un processo di progettazione in svolgimento. I partecipanti utilizzeranno Grasshopper (modellatore parametrico per Rhino): l'uso di questo editor grafico di algoritmi si integra alla perfezione con gli strumenti di modellazione di Rhinoceros 3D espandendo le possibilità di corstruire modelli parametrici altamente complessi. Per generare una complessità simile saranno utilizzati collegamenti live ai diversi programmi elencati di seguito: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI Durante questi intensi 3 giorni, i partecipanti impareranno il workflow dei plug-ins con l'aiuto di esempi esplorando una panoramica dei differenti software, le possibilità di testare le performances di un progetto o l'uso di strumenti addizionali non legati ad un singolo sistema (es. accentuazione, formazione, reazione parametrica) [english text] The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process. The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way. Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino's 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software's, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system .

curve or locus] of a segment AB, in English. The set of all the points from which a segment, AB, is seen under a fixed given angle.
When you construct l'arc capable —by using compass— you obviously need to find the centre of this arc. This can be easily done in GH in many ways by using some trigonometry (e.g. see previous —great— solutions). Whole circles instead of arcs provide supplementary isoptics —β-isoptic and (180º-β)-isoptic—. Coherent normals let you work in any plane.
Or you could just construct β-isoptics of AB by using tangent at A (or B). I mean [Arc SED] component.
If you want the true β-isoptic —the set of all the points— you should use {+β, -β} degrees (2 sides; 2 solutions; 2 arcs), but slider in [-180, +180] degrees provides full range of signed solutions. Orthoptic is provided by ±90º. Notice that ±180º isoptic is just AB segment itself, and 0º isoptic should be the segment outside AB —(-∞, A] U [B, +∞)—. [Radians] component is avoidable.
More compact versions can be achieved by using [F3] component. You can choose among different expressions the one you like the most as long as performs counter clockwise rotation of vector AB, by 180-β degrees, around A; or equivalent. [Panel] is totally avoidable.
Solutions in XY plane —projection; z = 0—, no matter A or B, are easy too. Just be sure about the curve you want to find the intersection with —Curve; your wall— being contained in XY plane.
A few self-explanatory examples showing features.

2 & 6 2nd ver. (SED) (ArcCapableSED_def_Bel.png)

4 & 8 4th ver. (SED + F3, Projection) (ArcCapableSEDProjInt_def_Bel.png)
If you want to be compact, 7 could be your best choice. If you prefer orientation robustness, 5. Etcetera.
I hope these versions will help you to compact/visualize; let me know any feedback.
