n the z axis I can not, here's the problem, because the movement is not only on the z axis, I can't do a serie with this vector. I tried to do it by differents columns or rows but its impossible for me.
2. Another problem. How I can fill a surface like this with tetrahedrons? What about change the size of this tetrahedrons? Is it possible like a fractal? :Si'm still working...
Thank you!
Finally I have completed the cloud!! I am a little bit fool. With the help of some sketches it was not so difficult! :).
I found the movement pattern of my tetrahedrons
Then I found the points inside my surface!
But now I cant create lines between points like in the begining of the process, with the pattern with points 1, 2, 3, 4. What I have to do?
??????????

Is your company registered and properly licensed?
It does not take foremost and good question to ask mover before you finalize the services of one. You must go with a mover that is registered and properly licensed.
How many years has your company been in relocation business?
This specific will give you an ideas about experience of a moving company. You must go with only a professional mover on your move. Don't consider only long history of a valerse but additionally check its perfect background in the business.
Are you insured or do you provided goods insurance on move?
It is essential to select an insured company or a company that provides you goods insurance service on your move. An insured mover will cover the loss if your goods are however damaged or lost in transit.
Do you have your own transportation vehicles and necessary equipments?
The good moving company has its own especially designed goods carriers and moving trucks for safe vehicles of goods from one spot to another. A good company has its own necessary equipments for easy packaging, loading, unloading and undoing of goods.
Do you provide warehousing or safe-keeping facility?
If you need storage of your household belongings for a period on your next new house purchase then you must ask this question. You need to go with a mover that also provide warehousing & storage facility.
Ask about the staff members and works of the company?
An individual must ensure that the staff member of company is professionally trained and friendly as well.
Ask about details of their previous customers or clients?
May hesitate to ask details or information of prior customers of the movers and packers. A good mover will almost always be happy to provide you references.
Aside from these questions you should never forget to make clear about price, services, concealed cost, surplus charge and other details which you need to know on your move. You must ask about written and biding estimates. You should go with a mover that delivers you written binding estimate for your next big move. In fact , you should make each and everything crystal clear before finishing the services of one great Packers and Movers in India. I hope you will find these pointers helpful.…
he example file to this file so you can give it a try with any version of Honeybee that you're already using. The only requirement is to have OpenStudio installed as the component is using OpenStudio libraries to parse gbXML files. If you're using the latest version available on github the component is also available under WIP tab.
Why?
The main purpose of developing this component is to save time and effort for importing Revit models for energy and daylight analysis. It bothers me to see a lot of smart people spend a lot of time to just come up with solutions just to get the geometry from Revit to Honeybee for analysis. This component is not solving all the issue but is a first step forward. In an ideal world, the future version of Honeybee, which works both under DynamoBIM and Grasshopper should address this issue but that can take some time to be fully ready!
How?
To use this component you need to Export your Revit model as gbXML and then use the file path to load the file into Grasshopper. There are several resources available online on how to prepare the analytical model in Revit and export the gbXML file. Here is an image for importing the Revit 2017 sample model using the default settings. As you can see the model will be just as good as what your original gbXML file from Revit is.
What can be improved?
Well, there are several items that can be improved and they are mostly not on us. To get it started I add what I think are the 3 main shortcomings and my thoughts on how they can be addressed in the future. Feel free to add what you think needs to be added to this list in the comments section.
1. Revit analytical models and as the results gbXML files, by design, are not intended to be clean. Watch this presentation from the Autodesk University to see the logic behind this approach which in short is it doesn't matter for a large scale early stage energy model. Well, This will be quite a problem for studies that you can do with Honeybee. Included but not limited to daylight and comfort analysis.
The best solution that I can think of, until Autodesk fixes their exporter, is to use Revit Rooms and Spaces and generate a clean model from the scratch. We have already tried this approach in Revit but since the Revit API doesn't provide access to Room openings we had a very hard time to get it to work.
That's why that I opened an idea on Revit ideas to get over this issue. With your support we already have 81 votes, but it hasn't been enough to make them to consider the idea for an official review. If you haven't voted already and you think this will be a helpful feature take a moment and vote so we can have it implemented at some point in the future.
2. There is no way (that I know) to export only part of the model. The way export gbXML is set up in Revit is to export the whole model once together. As a result, if you have a huge model with 100 rooms and you want to get one of the rooms into Honeybee using this component you have to export the whole model, which can take some time, and then import them all back into Grasshopper. To partially address this issue I added an input to the component that allows you input a list of names for rooms that you're interested to be loaded into Grasshopper. You can use the name of the room/space in Revit as an input for the component.
3. The component doesn't import adjacencies, loads, schedules and HVAC systems. I wasn't able to export a gbXML file from Revit with any of this data except for the adjacency, but even if you can do that, the component currently can only import geometries and constructions. I hope we get access to 1 and so we don't have to use the xml file approach at all, but if that takes a very long time then we will add these features to the component.
Happy 2017!

the daylighting and energy sim with Nat Vent create many complex questions.
Daylighting :
1. Adding shading to energy AND daylight simulation: Can I add HBconext to Honeybee_run daylight simulation HBobject input ?
Looking at the results it seems like daylight simulation doesn't recognize HBcontext, or maybe the difference is minute. Am I doing this correctly? Is there a possible error due to redundancy ? (meaning I am introducing the HBcontext twice, one time to the Honeybee_run daylight simulation AND energy simulation)
2. One of the component, Honeybee_Read annual result 1 keeps failing and says that ''1. Solution exception:index out of range: 0." I read here input needs to be internalize data but maybe there is a better solution?
Shading :
I want to study life cycle perspective of
A) Optimal ratio of fixed vs dynamic louvers for economic implementation,
B) Assess whether it makes more sense for the dynamic louvers to functions as light shelvs or the fixed ones for economic reasons
C) Simulate dynamic/fixed hybrid louver system schedule, and show it in a manner similiar to lighting schedule.
For this I would need to simulate the effect of dynamic and-or fixed shades in reducing annual lighting cost while reducing cumulative heat gain.
3_How to introduce Dynamic shading schedule for custom shades? Is this done with EPtranschedule input of the HB EP context component? I would like to keep the louvers branched so that it is possible to assign different modes i.e. fixed or dynamic
Light Shelf:
4_Is the lighting schedule effected by light shelves introduced in the annual daylighting simulation?
5_Does energy simulation take account of additional heat gain from light shelvs ?
6_When I use Honeybee_createHBSrfs with Honeybee_radiance Mirror material, it crashes rhino. The geometry input is not branched. Any report similar crashes?
Nat Vent:
I want to design to combine passivhaus principles with Natural ventilation.
My goal to simulate the energy performance of passivhaus house like building system with Bouyancy driven Nat Vent design which maximizing the percentage of the year Nat Vent takes care of ventilation and cooling, and in cloud days heat exchanger with fans kicks in.
using a trombe roof that heats air and using a vertical shaft that recirculate air, want to minimize the use of fans, Ducts, Heating etc. and I want to use the HB Set_Air flow component to evaluate such system if I can.
while I have heard that bouncy driven system may only be reserved for tall buildings, I still would to simulate the effectiveness for mid rizes and podium- types. I am skeptical whether there will be enough pressure difference for effective ventilation of 1.5ms so I would like to test.
How to set up models to evaluate bouyancy driven ventilation :
7 About HB Set_Air Flow, with Natural ventilation, If I use the HB Set_air the honeyzone output is null. I am not sure why, no error messages.
8_ When using the HB Set Air component to include Nat Vent with bouyancy,
does the result of reduced temperature to take effect into the cooling/equipment/ventilation schedule of the Honeybee_set Energy plus zone schedules?
Additionally I want to incorporate Nat vent analysis with the light shelf, since both would effect indoor temperature.
A wish list: as if it were all this has been not.
9_I wish there is something like a deconstruct honeybee zone component that basically breaks down all the options (mechanically ventilated or not) that is associated with the honeybee zones so that it is easy to document all the properties in text.…
giornata inaugurale sarà dedicata alla free-lecture introduttiva finalizzata alla realizzazione di un modello d'architettura complesso attraverso l'utilizzo di comandi e tecniche avanzate di rappresentazione con Grasshopper (plug-in parametrica di Rhinoceros) e 3dsMax. Sarà illustrato inoltre il potenziale di V-ray per 3dsMax realizzando un rendering concettuale. Durante il mini-corso dell' openDAY verranno mostrate le caratteristiche e le potenzialità degli strumenti per far luce sui nuovi valori assunti dalla modellazione 3D. La modellazione 3D sta interessando un pubblico sempre più vasto inserendosi in una nuova fase di ampia disponibilità per conoscenze, software, hardware di prototipazione e modelli. Pur mantenendo tutti i suoi valori già noti la questione si è talmente ampliata fino ad interessare norme giuridiche (diritti sui modelli ,concorrenza con offerte di servizi apparentemente simili, informazioni deformate e onfusione nei media) Makers University[http://www.makersuniversity.com], in collaborazione con parametricart, vi propone un punto di vista ampio e sintetico su queste tematiche.
Al termine della free-lecture, sarà illustrata l'offerta formativa [CLICCA QUI] di parametricart riferita ai corsi che si terranno nei mesi di Gennaio e Febbraio 2013 inseriti all'interno della più ampia programmazione della Makers University. SONO PREVISTE TARIFFE PROMOZIONALI PER COLORO CHE SI ISCRIVERANNO AI CORSI durante l'OpenDAY.
La lezione e la presentazione si terranno nel nuovo spazio co-working il PEDONE.

arq, que se celebrará entre el 28 de Enero y el 1 de Febrero de 2013 en el Colegio de Arquitectos de Granada.
El taller está destinado a arquitectos, artistas y diseñadores, tanto como profesionales, como estudiantes de grado y posgrado, que, sin necesidad de haber tenido ningún contacto previo con entornos de programación o herramientas informáticas de dibujo paramétrico o generativo, están interesados en probar y experimentar con las opciones que nos pueden ofrecer a los diseñadores.
El taller está dividido en tres bloques:
Curso intensivo: del 28 de Enero al 30 de Febrero, en horario de mañana, de 10 a 14. Taller de proyectos: del 28 de Enero al 30 de Febrero, por la tarde, de 16 a 20; y el 31 de Febrero, durante todo el día.
Presentaciones: viernes 1 de Febrero, mañana y tarde.
Utilizaremos Grasshopper, el editor algorítmico asociado al software de modelado tridimensional y dibujo Rhinoceros, por su facilidad de aprendizaje, al tratarse de un entorno gráfico, facilidad de adquisición, al ser gratuito y haber disponible una versión de prueba de Rhinoceros también gratuita, y amplia difusión en los últimos años. Y lo emplearemos tanto como modelador, como conector entre otros softwares y varias disciplinas. Por este motivo, también utilizaremos algunos de sus plug-ins, como Geco, para análisis ambiental, Elk, para enlazarlo con OpenStreetMap o Kangaroo, para simulación de sistemas físicos.
Lo único que necesitas es un ordenador portátil (si no pudieras conseguir), hacer el ingreso con el importe correspondiente y mandarnos tus datos y el recibo bancario del ingreso a smartlabgranada@gmail.com. Puedes ver los detalles en el apartado de Inscripción. El resto del material, tanto software como hardware, lo ponemos nosotros.
Nuestro acercamiento a estas herramientas es entusiasta acerca del potencial creativo que pueden ofrecer a diseñadores y artistas, pero también crítico y especulativo. Nos alejamos tanto de una posición puramente formalista, como del estricto funcionalismo, a los que desde los últimos años frecuentemente se ha asociado a esta disciplina.…

cess informing the user the network is incomplete.
I've been thinking for a while about reading in these blobs of incomprehensible data in an attempt to maintain them through an open/save cycle, but I'll never be able to get this process watertight.
2) When you release components, you should try and make sure that they are backwards compatible previous releases. For example, if you decide to change the number of inputs/outputs or the type of inputs/outputs, this might well break file IO. What you should do in those cases is:
- Copy-paste the old component source code and change the ComponentGuid property. In essence, you make a different component which will have the changes.
- Change the Exposure property on the old component to be GH_Exposure.hidden. This will hide the component from the interface.
This basically means that when people open a file that uses the old style component, they'll get the old-style component. If people instantiate the component anew, they'll get the new component.
Grasshopper and it's default gha assemblies feature dozens upon dozens of these hidden components, sometimes there's as many as 4 old-style components out there.
3) If you want to store additional data in the ghx file for a specific component, you'll need to override the Read() and Write() methods. Something like this:
Public Overrides Function Write(ByVal writer As GH_IO.Serialization.GH_IWriter) As Boolean
writer.SetBoolean("MySpecialBooleanValue", m_myBoolean)
writer.SetString("MySpecialStringData", m_myString)
Return MyBase.Write(writer)
End Function
and
Public Overrides Function Read(ByVal reader As GH_IO.Serialization.GH_IReader) As Boolean
m_myBoolean = False 'Default state
m_myString = String.Empty 'Default state
reader.TryGetBoolean("MySpecialBooleanValue", m_myBoolean)
reader.TryGetString("MySpecialStringData", m_myString)
Return MyBase.Read(reader)
End Function
It is usually possible to make the Reading process smart enough to handle backwards compatibility. You can ask the reader object whether or not a certain value exists and you can then decide whether you can safely use old or new reading logic. So any changes to this part probably don't require you to create a duplicate component and hide the old one.

an almost planar tissue (your case) can cause a variety of issues up to the undo able state (metal parts/components grow in size as well for no reason). See forces estimated by FF below.
2. Therefor I strongly suggest to consider Plan B (a) mastermind a secondary "anchor" capability in order to achieve a far more stable system (b) use a mount design that can support this (and comply with the attractor concept of yours). Here's a variable mount custom system (mostly machined AND not cast) that is suitable for the scope (Rhino reads the stp file OK .... but makes a colossally big file - thus I attach here the original).
3. On first sight lot's of things in this system appear "odd". For instance: is it stable? Why these double cables are used? How far can be adjusted? (that's a classic case for feature driven parametric design - not doable with Rhino).
4. This concept (strut axis exported only) is tested in FORMFINDER and some other far more complex membrane apps that I use quite often (not RhinoMembrane). Here's is what FF tells us about:
Observe a different kind of "stress" when this is converted to radial type:
5. If you insert the stp file to the Rhino file provided (exactly as exported from FORMFINDER - no mods of mine of any kind) you'll see what goes where (and why). That way the usage of double cables is rather obvious (and a lot other things - for instance the way that the struts achieve "equilibrium", see the slots in the base mount plate.
6. If this approach is worth considering your definition requires some serious rethinking (far more simpler/manageable with the drawback that the real parts they are "static" they can adjust only as far this particular solution allows them to do - controlling them parametrically is clearly impossible with the current state of R/GH capabilities).`
All in all: this case works because the cables push the anchor points downwards and the struts push them upwards.

s mostly related with panelization. Panelization means many things, for instance (1.1) designing an aluminum facade system (most common case: "hinged" extrusion profiles that contain opaque or transparent materials - the "facets"), (1.2) designing insulation and final "coating" in roofs, (1.3) ... (1.n) continue at infinitum.
2. Let's stick to the least understood (and less glamorous) part : topic (1.2). The best core material for the core job is FOAMGLAS:
http://www.foamglas.co.uk/building/applications/
3. Most ignorants in our trade believe that the main point/task of a thermal insulation is the U thing. But in fact is the Dew Point (DP) management the most important of them all (DP = critical temperature at witch the relative humidity reaches saturation). Thus we arrive to the compact "roof" (or some compact "part" of the AEC thing) matter: (3.1): Dew point INSIDE the thermal insulation, (3.2): no thermal bridges, (3.3): no air from the application medium (say plywood, corrugated/flat sheets, special Foamglas Px panels etc etc) up to to the water proofing membrane(s) (say 2 layers of SBS bituminous membranes). Here's the most typical case of them all (special tapered inserts not shown - notice the cladding fixing method without perforating the sheets, no other insulating material can do that):
4. The above image brings us directly to Kangaroo matters (if we add the "liquid" thing meaning no linear geometry around). By "liquid" I mean that our working surface is no more "flat":
In particular we must: (4.1) test if the corrugated sheets can follow the curvature (they can up to a point), (4.2) test if the FOAMGLAS panels (straight "boxes") can safely AND FULLY adhere to the medium without spending the GNP of Nigeria to do it (*), (4.3) test if the VM Zink (or Kalzip) cladding systems can cut the mustard - they are more flexible than the corrugated sheets (and can been tapered on-the-fly, Germans are very innovative on that matter) ... but... well ... you understand where the issue is, I do hope.
(*) you can use 85/25 bitumen (cheap and nightmare to put it) or PC500 (very expensive and easy to apply). Obviously some mechanical fixing is required as well.
And what is the most important test of them all? Well ... the 4.2 thing, what else?
more soon.
