f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

ata1...3_" mean? Additionally what do I connect to _HBObjects? Windows or shading geometry? Then what is expected to come out of "windowBreps","shadeBreps" and HBObjWShades? I ask as it was skipped in your video tutorials. If I am not correct, please give me a hint where I can find it.
But I am obviously curious of what is the best way to test elements that substitute each other according to the schedule. If this was a tool this would be EXTREMELY powerful as it one of fundamental strategies in adaptive architecture.
Unfortunately, I do not know what happens behind the interface as before I have been an EDSL TAS user which is promoted at the AA school as user friendly).
The flow for the NatVent settings in the proposed settings is suitable for preliminary studies. However it would be helpful to control apertures by the weather data in a more tricky way. I mean that the input should be dynamic and obviously instead of using the outdoor temperature to open or close the window I would prefer to use the indoor DBT which appears dynamically while the conditions are calculated. Anyway you should know better!
Thank you for prompt help.

The type of recipe appears to be related to the problem, because de error desolves when I connect the component to a different recipe.
A screenshot of the complete error message is in the attachment.

e design intent, but this is what Inventor is good at. The way it packages bits of 'scripted' components into 'little models' that can be stored and re-assembled is central to MCAD working. The big speed/usability advantage for the user that apps like Inventor provide is: All the defining, handling, assembling/gluing to the adjacent components is done as part of its 'main loop' with all the hooks that can cater to user interaction, ie traditional modeling. I guess one example of this is how Revit handles the placing of Adptive Components. AC's (and GC's GFT's) is pretty much a copy of Catia PowerCopies (which are probably a copy of something else). When placed, the AC's input points are transferred one by one to the cursor for the user to interactively place them. When copied, it tries to keep the same inputs, while changing its position/parameters. This saves a lot of time/nerves.
Catia, OTOH, is still thinking in terms of scripting and looks for matching property names, or uses a script to match strings, that nearly match. Sure, sometimes, this is unavoidable, but I think that there is a lot of room for incorporating a more traditional 'event-based' interface or 'wrapper' around the scripted components.So much is scripted in GH, maybe it should also be possible to script/define/constrain/assist the placement/gluing of the results? An example of this is how Modo's Toolpipe works. The Toolpipe is a simple tool to record the active selection, snap/alignment/working plane, tool settings for re-use. I could see the user benefitting if the GH component was aware of the app's 'state' when placing/assembling components.
Also, a lot of simple things could be 'modeled' first and translated into scripted form if GH could read the active workplane, snap settings etc. Draw first, convert to hand-scripted script later?Columns: Looking at your description, the vertical elements were modeled in Rhino, and referenced in GH? 5hrs to get some points on the lines? And using Excel as the design table? I think this could be 'drawn' and constrained in Inventor in a lot less time. I know the GH model would have a lot of flexibility, but in this case, what can you do with it that wasn't provided by an Inventor model? The other thing that MCAD apps like Inventor have, is the 'structured' interface that offers up all that setting out information like the coordinate systems, work planes, parameters etc in a concise fashion in the 'history tree'. This will translate into user speed. GH's canvas is a bit more freeform. I suppose the info is all there and linked, so a bit of re-jigging is easy. Also, see how T-Flex can even embed sliders and other parameter input boxes into the model itself. Pretty handy/fast to understand, which also means more speed.Would love to understand what you did by sketching.Starting point: I think we are talking across purposes. AFAIK, the solving sequence of GH's scripted components is fixed. It won't do circular dependencies... without a fight. The inter-component dependencies not 'managed' like constraints solvers do for MCAD apps.
With a manager, If one of the beams is connected to the column, changes in either component would trigger changes in the other to preserve the connection, regardless of the creation history. In GH, the dependencies are fixed, and the connection points would probably need to be defined independently, and placed 'upstream' of both elements. This makes editing laborious... but DAG processing is a lot quicker than constraints solving. Switching direction seems to be possible in the animation world. Maya etc have IK/FK switching, which seems to be able to reverse the solving direction on demand. Not sure how or whether the rig is scripted.…
. 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?

se (like in nature). the length of the sticks shall be controlled by the brightnessvalues of a picture. so the bend have to be controlled, too.
now we have several problems:
1. how can i map a hexgrid on a curved surface?
2. how can i adapt the grid to the dimensions of the surface (no overlap, no gaps to the bound)?
3. important
: to create the curved sticks, we use points on a line and we move some of them and then we want to connect the right points via interpolated curve to create each curved stick. now the problem is that the points have to been filtered in the right way. we know that we have to filter each list of points to the index values of the points. the number of index values is the number of hexgrid rows, so there are a lot and we can't use a list item for each one. it could be hundreds.
is there any opportunity to sort a list after the index values (first every index=0, then index=1, ...n)?
or is there any component which does a group of operations for n-times (n is the flexible number of index values) ?
4. how can i control the length and bend of the sticks via the brightnessvalues of a picture?
please help us. thanks.
german version:
In einem hexagonalen Raster soll sich senkrecht zu Oberfläche ein Stab im Mittelpunkt jedes Sechsecks befinden. Dieser soll sich ab einem gewissen (festgelegten) Punkt Richtung Boden biegen. Zusätzlich wird die Länge des Stabes zum Beispiel durch die Information eines Bildes gesteuert, so dass auch die Biegung, je nach Länge, geregelt werden muss.
Wir haben ein Hexagonales Grid (HexGrid) erzeugt und in jeden Mittelpunkt eine Linie senkrecht zum Grid erzeugt, aus der wir uns Punkte mit CurvePoint ausgeben lassen. Der letzte ist verschoben, um eine Biegung zu simulieren. Um die Punkte zu einer interpolierten Kurve zu verbinden, müssen sie nach dem Index sortiert werden. Gibt es eine andere Möglichkeit, als jeden einzelnen Indexwert über ein ListItem herauszufiltern (Da die Rasterung flexibel einstellbar sein soll, entstehen n Indexwerte)? Oder kann man eine Liste nach den Indexwerten, also nicht nach den Punkten, sortieren?
Und wie kann man über Bildhelligkeitswerte die Länge der Stäbe und damit auch die Biegung steuern (ein kurzer Stab biegt sich weniger als ein langer Stab)?
Gibt es die Möglichkeit ein hexagonales Raster auf eine gekrümmte Fläche zu mappen?
Und wie passt man ein solches Raster (HexGrid) in eine Fläche mit definierten Maßen ein, ohne dass das Raster an den Rändern übersteht oder die Fläche nicht vollkommen ausfüllt?
danke.…
