ture which is combined with some columns. The columns are arranged in a straight grid structure. I’m not able to get a smooth transition between structural curves as you can see in the image.
Problem 1: I was able to make the columns out of 4 curves, I need this to be 8.
Problem 2: I want to be able to manipulate the column posiotions by XYZ.
Problem 3: The curves (these two curves should be a dome like structure) from two columns aren’t conecting smoothly as you can see in the green ellipse in the image below.
After I created the column curves ( blue circle) in grasshopper (file: 'Surface+Columns' and 'columns2') I made solid columns out of it and tryed to join them smoothly with the surface to project a grid structure on it (in rhino).
Unfortunatly I went wrong and the problem is which you can see in the red ellipse:
The column pipes aren’t on the same level like the grid structure of the surface. Somethimes they are on, sometimes under the surface.
Could somebody help me please, That would be absolutly great!! :)
In the file 'Surface' you'll find the Surface with the current column possition.
Here you find a few reference pictures, but actually it should look like on the rendering below - just properly :)

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

complicated than it seems as I have an event and a subscriber method receiving data from a serial port.
In the code below, the strings received within myReceivedLines appear when connecting with the serial port (when connecttodevice is true). However they disapear when I launch another command (when homeallis true).
As you recommended in your reply, I have added the field called myReceivedLineswithin the class so that I could use the method String.Add() to all the feedback received and commands sent.
Why does the feedback dispear when a command is sent? Is the string going to myReceivedLine disappearing because they happen within a subscriber method or is it related to the DA.SetDataList() method used to assign myReceivedLinesto the output?
Many thanks!

sent a 3D shape without any ambiguity. If the shape you're trying to convey falls outside the scope of existing standards, then it can't be done, but this is a problem of standards, not an intrinsic shortcoming of pencils.
[...] with the computer theoretically acting as a decision maker.
The computer makes no decisions on it's own. It's a fully deterministic machine, meaning that any output is the result of applying a set of rules to some pre-existing data. Humans make the rules. At no point can you blame the computer for coming up with a bad answer, it's always some human who is responsible.
[...] it seems to often be split between Computerization, and Computation.
I'm willing to concede there exist cases that are unambiguously one or the other, but there's a gradient in between these two extremes, they are not separate categories. If I draw a box by specifying the 8 corner points as XYZ coordinates then computation can be said not to be involved. If I draw a box by specifying 2 opposite corners then the computer has to compute the other 6 coordinates and we're already on our way towards the other extreme. If I draw a box by specifying a width, height and a required volume, more computation is needed. If I specify a box by a width, a volume and the requirement is doesn't cast too much shadow on some other shape, more computation is needed. At what point do we say "now it qualifies as computation/solving"?

be due to memory issues, but I did see the run time go from, no kidding, 5-1/2 hours down to 1.5 minutes; as this logic simply removes duplicate curves in groups, and then runs it again to further remove duplicates, should not be missing any curves. I haven;t tested it extensively, but results were the same for a straight curve removal (5.5 hours) and the 'page swapped' method outlined (1.5 minutes). So called page swapped, as it is one of the old methods used by intel and others to manage memory on slow processors, from the 1970's.
This method also works to cure the "region union" bug, again coming up with an outline curve from your tree definition. Not only was it fast (45 seconds) it actually worked! on a large curve set (3,000 + curves).
Is it a generic method? Don't know. worked well in these two cases though, and is both 2 orders of magnitude faster, and embarrassingly idiot simple; so simply that I was actually not sure if I should show it, as I do not want the group to think I have the skills of an 8 year old (actually that used to be an insult; with today's kids, might be a compliment)
I am interested to hear if it work in other cases.
Oh! I left out the last line in the sequence, the last component should be a repeat of the duplicate lines command without partition the set so indeed not to miss any curves. Same for a 'region union" sequence
By the way, your scripts, tools and examples are fantastic! - I and others have used them as starting points for various projects.
here is the full sequence

Its about making radiant temperature map, but it gives some errors such as:
1. The length of data in the comfResultsMTX does not matech the number of faces in the viewFactorMesh.
1. Solution exception:index out of range: -2
Its just simple box building that simulation itself doesn't take long, and I've updated my HB and LB components and everything seems ok. But still having the problem. Since the components have major and minor changes I've managed to connect _comfResultsMtx to the read Comfort result component to do the simulation, however it has some other issues as well.
The components error message says
1. Failed to parse the result file. The csv file might not have existed when connected or the simulation did not run correctly.Try reconnecting the _resultfileAddress to this component or re-running your simulation.
So the question is how to achieve radiant temperature map? and could it be done in specific analysis period instead of annual cycle?

e and i get it. If you have time check the attached papers we published a while ago in relation to the contribution of thermal mass in the reduction of temperature in residential buildings. See the nice contribution of the heavy TM or the lower one for light TM.
As for the solarHeatCapacity, your description (of the 50W) is derived on a 1 Facade/Floor ratio and fully glazed. The only way to reduce it is to increase the ratio (bigger facade area). Which is not recommended (energy losses), but this is a different issue. So, roughly, we can say that 50 is the lower value. If i have less glazing area this number will be higher (right?)
I want to define a value list of "architectural situations", so it is easy to explain and understand. One situation can be:
"Ratio facade/floor 1 & Fully glazed" = 50
"Ratio facade/floor 1 & Half glazed" = 75
"Ratio facade/floor 1.5 & Fully glazed" = 30
"Ratio facade/floor 1.5 & Half glazed" = 50
"Ratio facade/floor 0.75 & Fully glazed" = 70
"Ratio facade/floor 0.75 & Half glazed" = 90
Makes sense for you something like this?
I also defined a value list for the timeConstant like this:
Light Building (Mobile home) = 1Medium-light building (Cement tiles on floor) = 4Semi Heavy Building (Concrete floor + Tiles) = 8Heavy Building (Concrete floors/ceilings + Heavy external and internal walls) = 12
As for the first 5-10 cm effective TM in general my assumption is that you take half of the mass to your space and half to the space above/below you. Will be interesting to do a parametric study on just the thermal mass, uninsulated and insulated to see what the depth limits effectivity will be. Interested in doing such a study together? Can be a nice work even for publishing.
Thanks a lot ... again,

ALISTICO. Ciascun modulo si svolgerà nell’arco di due giornate e si potrà scegliere se partecipare ad entrambi i moduli o altrimenti solo all’uno o all’altro.
In questo corso si insegneranno nuove tecniche di modellazione parametrica attraverso l'utilizzo di Grasshopper, rivoluzionaria plug-in di Rhinoceros. Grasshopper permette di esprimere al massimo le qualità e le potenzialità della modellazione Nurbs, abbandonando in parte l'interfaccia classica di Rhinoceros. Quest'ultimo infatti viene sostituito da un menù a tendine nel quale vengono collezionati nodi utili alla composizione di algoritmi risolutivi.
La plug-in Grasshopper, dimostra come il linguaggio del computer stia diventando un reale strumento progettuale.GRASSHOPPER-BASE - 8 oreil giorno 09/05/2013 dalle 10.00 alle 19.00
Nella prima parte del corso si insegneranno i metodi di esplicitazione degli algoritmi, applicati ad esercizi base utili alla comprensione del software. In queste ore si illustreranno, attraverso fasi operative, i seguenti argomenti:
Suddivisione degli algoritmi in parametri e componenti;
Tipologie di dati compatibili con Grasshopper e loro combinazione creando definizioni minime;
Funzioni matematiche e logiche
Data flow, liste e filtri di esclusione.
Costruzione di curve e superfici e loro trasformazione.
Scadenza preiscrizione per Grasshopper - BASE : 06/05GRASSHOPPER-SPECIALISTICO - 8 oreil giorno 10/05/2013 dalle 10.00 alle 19.00
Nella seconda parte del corso lo strumento viene specializzato affrontando editing e trasformazioni complesse sulle superfici:
Elaborazione delle superficie di suddivisione;
Tassellazione spaziale di superfici a doppia curvatura;
Gestione di parametri variabili per la progettazione di definizioni finalizzate al controllo del movimento;
Ideazione di algoritmi per il passaggio dal modello digitale al modello reale attraverso la tecnica dello sliceing.
Scadenza preiscrizione per Grasshopper - SPECIALISTICO : 07/05
