or Ladybug and Honeybee:
1. Our recent presentation at IBPSA-NYC is now available online. We do an overview of what Ladybug and Honeybee capabilities with a short live demo:
part 1: https://vimeo.com/107501953 - part 2: https://vimeo.com/107502226
2. Chris recorded a great set of tutorials together for "Getting Started with Ladybug" that walks you through several components in Ladybug: (https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O)
3. He (Chris) also recorded another great set of videos for comfort tools that he is currently developing for Ladybug and Honeybee: (https://www.youtube.com/playlist?list=PLruLh1AdY-Sho45_D4BV1HKcIz7oVmZ8v)
4. With the help of Mohammad, we finally uploaded the videos from the workshop that I led at Penn few months ago which covers Daylighting with Honeybee: (https://www.youtube.com/playlist?list=PLkjfDmSc5OryXkWSt57ltJFU4qXD5ss1v)
5. Finally, Chris also started a series of videos on Energy Modeling with Honeybee that you can watch here: (https://www.youtube.com/playlist?list=PLruLh1AdY-SgW4uDtNSMLeiUmA8YXEHT_)
There are couple of stuff which are coming next, soon:
1. So Young is modifying the videos for the Ladybug workshop and once they are ready, we will upload them.
2. I will be capturing a number of videos for developers soon. We are so excited to see all the new developers joining the team and we understand the need to support you to get started. I hope these videos can help you to understand the development logic and get you started with the development.
OK. Now if you have access to Internet, which I supposed you do as you are reading this online, you have no excuse not to learn Ladybug and Honeybee. :)
Let us know your comments and suggestions.
Cheers, Mostapha…
this was about some boring building I wouldn't respond ... but here we are talking sardines.
Here's my take on that matter:
1. The 4 C# first create/use a nurbs, then define some random planes (and transformations) and then (a) either they place some humble stripes or ... er ... (b) sardines as instance definitions (NOTE: Load Rhino file first).
2. All important decisions are the ones in yellow groups.
3. You control what you get via this (priority on stripes or sardines? that's the 1M Q):
4. If you decide for sardines (the right thing to do) then you must ENABLE the Sardiniser(C)(tm)(US patent pending) as follows:
5. The vodkaFactor on that Sardiniser C# adds some spice in the sardine placement (it does that by altering the priority on the "composite" transformation in use: first randomly rotate then planeToPlane .... or the other thing?).
6. Only the finest Da Morgada sardines are used in this definition:
7. Spot the WARNING in the filter related with what sardine to choose > do it wrong and no hard disk on your workstation > no risk no fun > sorry Amigos, he he.
8. 1M question for you all: why placing sardines (it's real-time you know) is WAY faster than creating these humble stripes?
9. Although the sardines are placed in real time as regards your CPU ... the critical factor is your GPU (display mode: rendered).
10.Still WIP (dancing sardines in the next update).
have some sardine fun, best, Lord of SardineLand…
use Google's API, especially if you'd like to achieve a great quantity of data without overloading Google's servers.
I used a way to request data without overloading Google's servers by using a tiling method. Obviously, this component respects the limit of 2500 requests per day.
This is how the component works:
1) set one point and its coordinates
2) generate surfaces by using isotrim component (Basically, each sub-surface is a request)
3) set the number of division of each surface and the resolution of Google static maps
4) run, move points and generate surfaces with surface from points
5) apply textures to the surfaces
In the image below another small example:
I was thinking that this should be useful for wind simulation with Butterfly, maybe.

and Grasshopper. Recently I tried doing some test project just to see what can I do. My target is to design a small house for an atom family. Though as you might think - it'll be a parametric one. And I encountered exactly what's in the title. So here it goes: 1. Something is wrong with the measuring units in the complex profiles. I met this problem while making I-beam. In ArchiCAD it had 127/76 mm while in Grasshopper i had 127000/76200mm so a little bigger. 2. I'm unable to turn off the preview. I mean when I delete something in Grasshopper/Rhino it still exists in ArchiCAD. I have to unlock it and then delete it. 3. Coordinates for points seem broken. They have to be multiplied 1000 times to match. 4. Now one of the most important. Is it possible to somehow SHOW Grasshopper where are already made in ArchiCAD objects. Even if they'll remain still. For example I want to make a parametrical roof. Do I have to model whole building from scratch in Grasshopper or is there some fast way to "import" existing scene so I can limit my work with Grasshopper only to parametrical one. 5. Is it possible to make "points" as controlling points in AC? Like, if I'd like to make a beam in a desired place which I will mark by that point and then I will "show" Grasshopper that point and tell it to make an object in there so I can control it within grasshopper. I tried ti do this using AC Control Point but when I click "Send changes" button, Grasshopper and Rhino crush immediately. It only happens then, with control points. 6. It seems that "move" component won't work with "2D curve" component connected directly. It is possible that some of those problems are outdated. I was playing around in Grasshopper a few months ago, before summer break, but now I plan to try something new and it would be nice to know what to do. I appreciate any answer to any of those questions. Please help, you guys, are my only hope. Thanks in advance! Karol…
. 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?
Results for ParisOrly.epwM,D,H:1,1,12

I have diagonals (bracings) which can buckle in these "non-regular" directions too, and they do. If I could add those values then in the Karamba model I could assign specific buckling scenarios..... I can see another challenge which will be at the ModifyElement component, I will not be able to choose these buckling lengths, in these directions.
Do you think this functionality can be added within short, or should I try to find another way to model these members?

diseño, construcción y entendimiento de nuestro entorno.
BIM está poniendo a disposición de los diseñadores y gestores auténticas bases de datos que pueden generarse, conectarse y editarse de forma paramétrica, proporcionando una sólida capa de realidad a los ejercicios de diseño generativo y computación que son objeto de estudio en Algomad, el seminario que busca popularizar la programación y la parametrización en el diseño y en la experiencia de nuestro entorno construido.
Tras un paréntesis en 2015, Algomad vuelve con el objetivo de demostrar cómo una visión computacional del BIM es una oportunidad para mejorar la forma de trabajar de ingenieros, arquitectos, constructoras y operadores de edificios e infraestructuras, tendiendo un puente entre las técnicas de diseño digital más avanzadas y la realidad de la construcción.
Algomad 2016 tendrá lugar en el centro de Madrid, en IE School of Architecture and Design, IE University, los días 3, 4 y 5 de Noviembre de 2016 y comprenderá 4 talleres así como ponencias a cargo de expertos de primer nivel.
Estructura de Algomad 2016
Algomad 2016 se estructura en torno a tres áreas temáticas principales:
BIM, como la metodología total específica para el sector de la construcción.
Computación, englobando las aplicaciones de programación y parametrización al diseño de edificios e infraestructuras.
Realidad, como marco de trabajo, buscando siempre resolver problemas reales a través de los dos puntos anteriores.
Público objetivo
Arquitectos, arquitectos técnicos, ingenieros y en general académicos, estudiantes de últimos cursos y profesionales del mundo inmobiliario y de la construcción que compartan un interés por la digitalización de nuestro sector. Se espera un nivel mínimo en el uso de herramientas BIM y de parametrización. Algomad proporcionará formación adicional y gratuita en las herramientas básicas a emplear en los talleres para asegurar un correcto desempeño.…
imes. Your loop should go to y.Count - 1. Or, you could use a For...Each loop, circumventing the problem altogether:
Dim shortLines As New List(Of Line)
For Each segment As Line in y
If (segment.Length < x) Then
shortLines.Add(segment)
End If
Next
A = shortLines
--------------------------------
Another problem is this line of code:
New_Lines.Add(New_Line)
It is located inside the loop but outside the If statement, meaning it gets run every single iteration. This fills up the short line list with duplicates.
-------------------------------
Here's something else which is redundant:
Dim Input_Line As New Line
Apart from the fact that you don't need a special variable for this at all, you also don't need to add a New keyword. The type Line in RhinoCommon (just like Point3d, Vector3d, Plane, BoundingBox etc. etc.) are Structures, not Classes. Structures always exist when they are defined, whereas Classes can be null ("Nothing" in VB).
-------------------------------
Some more advice:
Dim i As Integer
For i = 0 To y.Count()
You can merge these two lines into one. VB.NET allows you to declare your iteration variable inside the loop:
For i As Integer = 0 To y.Count - 1
--------------------------------
If you don't like the For...Each approach at the top of this answer, here's how to write this using a For...To loop:
Dim shortLines As New List(Of Line)
For i As Integer = 0 To y.Count - 1
If (y(i).Length < x) Then
shortLines.Add(y(i))
End If
Next
A = shortLines
ps. A personal preference of mine is that I always encase the expressions inside If...Then statements in brackets. You technically don't need to do this, but I find it makes the code more readable.

itects are at the spoke of a number of different specialties, and their work affects many different people. It's not like an architect is a painter, whose work may offend or upset the occasional viewer. As an architect you have a responsibility to produce quality work. How can anybody trust you with this responsibility if you're taking a purely artistic approach? What guarantees do you have that your clients money won't be spend on a poorly designed project if you can provide no rational for why your design is the way it is?
2. What is any sense in purely architectural discourse?
I don't get. Discourse is there to flesh out problems and agree on solutions. It might not always accomplish that, but what's the difference between talking about architecture as opposed to any other topic?
3. strictly looked, can be determined sense generally in a purely architectural discourse?
I'm sorry I don't understand.
4. What is purely architectural discourse?
I imagine it's having a discussion where you only talk about architecture?
5. What is Funktionalismus or Rationalismus without philosophical support?
Functionalism and Rationalism are ideologies. Some would even call them methodologies. They are inherently philosophical things as they are nothing more than a collection of ideas and views. As a society we've decided that a certain level of rationalism is a good thing. The Enlightenment continued this trend after the Dark Age hiatus and it quickly led to a large number of very tangible benefits for almost everyone.
I'm not arguing for or against Functionalism as an architectural style. I'm asking for a measure of rationalism in our academic process.
6. Would not be the pure functional fulfilment empty ?
Let's find out. In the meantime I'll settle for a little functionalism.
7. Would be not a critical position on the promise of purely rational algorithms applied?
Algorithms and algorithmic design are rational in the sense that they do not allow for ambiguity. But that doesn't make them rational in the real-world sense. These are not the same kind of 'rational's. I can make an algorithm that produces total nonsense, but does so completely reliably. I can also use an algorithm in a setting for which it wasn't intended, thus invalidating the results.
This is actually the crux of the problem. Which algorithms does one use to solve a problem and what data do they require? If you can't answer this question or if you do not understand the algorithms you are using (at least on a superficial level) then I'd say you have no business using them.
