ion of both Ladybug and Honeybee. Notable among the new components are 51 new Honeybee components for setting up and running energy simulations and 15 new Ladybug components for running detailed comfort analyses. We are also happy to announce the start of comprehensive tutorial series on how to use the components and the first one on getting started with Ladybug can be found here:

Here is a short list highlighting some of the capabilities of this current Honeybee release:
1) Run EnergyPlus and OpenStudio Simulations - A couple of components to export your HBZones into IDF or OSM files and run energy simulations right from the grasshopper window! Also included are several components for adjusting the parameters of the simulations and requesting a wide range of possible outputs.
2) Assign EnergyPlus Constructions - A set of components that allow you to assign constructions from the OpenStudio library to your Honeybee objects. This also includes components for searching through the OpenStudio construction/material library and components to create your own constructions and materials.
3) Assign EnergyPlus Schedules and Loads - A set of components for assigning schedules and Loads from the Openstudio library to your Honeybee zones. This includes the ability to auto-assign these based on your program or to tweak individual values. You can even create your own schedules from a stream of 8760 values with the new “Create CSV Schedule” component. Lastly, there is a component for converting any E+ schedule to 8760 values, which you can then visualize with the standard Ladybug components
4) Assign HVAC Systems - A set of components for assigning some basic ASHRAE HVAC systems that can be run with the Export to OpenStudio component. You can even adjust the parameters of these systems right in Grasshopper.
Note: The ASHRAE systems are only available for OpenStudio and can’t be used with Honeybee’s EnergyPlus component. Also, only ideal air, VAV and PTHP systems are currently available but more will be on their way soon!
5) Import And Visualize EnergyPlus Results - A set of components to import numerical EnergyPlus simulation results back into grasshopper such that they can be visualized with any of the standard Ladybug components (ie. the 3D chart or Psychrometric chart). Importers are made for zone-level results as well as surface results and surfaces results can be easily separated based on surface type. This also means that E+ results can be analyzed with the new Ladybug comfort calculator components and used in shade or natural ventilation studies. Lastly, there are a set of components for coloring zone/surface geometry with EnergyPlus results and for coloring the shades around zones with shade desirability.
6) Increased Radiance and Daysim Capabilities - Several updates have also been made to the existing Radiance and Daysim components including parallel Radiance Image-based analysis.
7) Visualize HBObject Attributes - A few components have been added to assist with setting up honeybee objects and ensuing the the correct properties have been assigned. These include components to separate surfaces based on boundary condition and components to label surfaces and zones with virtually any of their EnergyPlus or Radiance attributes.
8) WIP Grizzly Bear gbxml Exporter - Lastly, the release includes an WIP version of the Grizzly Bear gbXML exporter, which will continue to be developed over the next few months.
And here’s a list of the new Ladybug capabilities:
1) Comfort Models - Three comfort models that have been translated to python for your use in GH: PMV, Adaptive, and Outdoor (UTCI). Each of these models has a “Comfort Calculator” component for which you can input parameters like temperature and wind speed to get out comfort metrics. These can be used in conjunction with EPW data or EnergyPlus results to calculate comfort for every hour of the year.
2) Ladybug Psychrometric Chart - A new interactive psychrometric chart that was made possible thanks to the releasing of the Berkely Center for the Built Environment Comfort Tool Code (https://github.com/CenterForTheBuiltEnvironment/comfort-tool). The new psychrometric chart allows you to move the comfort polygon around based on PMV comfort metrics, plot EPW or EnergyPlus results on the psych chart, and see how many hours are made comfortable in each case. The component also allows you to plot polygons representing passive building strategies (like internal heat gain or evaporative cooling), which will adjust dynamically with the comfort polygon and are based on the strategies included in Climate Consultant.
3) Solar Adjusted MRT and Outdoor Shade Evaluator - A component has been added to allow you to account for shortwave solar radiation in comfort studies by adjusting Mean Radiant Temperature. This adjusted MRT can then be factored into outdoor comfort studies and used with an new Ladybug Comfort Shade Benefit Evaluator to design outdoor shades and awnings.
4) Wind Speed - Two new components for visualizing wind profile curves and calculating wind speed at particular heights. These allow users to translate EPW wind speed from the meteorological station to the terrain type and height above ground for their site. They will also help inform the CFD simulations that will be coming in later releases.
5) Sky Color Visualizer - A component has been added that allows you to visualize a clear sky for any hour of the year in order to get a sense of the sky qualities and understand light conditions in periods before or after sunset.
Ready to Start?
Here is what you will need to do:
Download Honeybee and Ladybug from the same link here. Make sure that you remove any old version of Ladybug and Honeybee if you have one, as mentioned on the Ladybug group page.
You will also need to install RADIANCE, DAYSIM and ENERGYPLUS on your system. We already sent a video about how to get RADIANCE and Daysim installed (link). You can download EnergyPlus 8.1 for Windows from the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/?utm_source=EnergyPlus&utm_medium=redirect&utm_campaign=EnergyPlus%2Bredirect%2B1).
“EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings.”
“OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.”
Make sure that you install ENERGYPLUS in a folder with no spaces in the file path (e.g. “C:\Program Files” has a space between “Program” and “Files”). A good option for each is C:\EnergyPlusV8-1-0, which is usually the default locations when you run the downloaded installer.
New Example Files!
We have put together a large number of new updated example files and you should use these to get yourself started. You can download them from the link on the group page.
New Developers:
Since the last release, we have had several new members join the Ladybug + Honeybee developer team:
Chien Si Harriman - Chien Si has contributed a large amount of code and new components in the OpenStudio workflow including components to add ASHRAE HVAC systems into your energy models and adjust their parameters. He is also the author of the Grizzly Bear gbxml exporter and will be continuing work on this in the following months.
Trygve Wastvedt - Trygve has contributed a core set of functions that were used to make the new Ladybug Colored Sky Visualizer and have also helped sync the Ladybug Sunpath to give sun positions for the current year of 2014
Abraham Yezioro - Abraham has contributed an awesome new bioclimatic chart for comfort analyses, which, despite its presence in the WIP tab, is nearly complete!
Djordje Spasic - Djordje has contributed a number of core functions that were used to make the new Ladybug Wind Speed Calculator and Wind Profile Visualizer components and will be assisting with workflows to process CFD results in the future. He also has some more outdoor comfort metrics in the works.
Andrew Heumann - Andrew contributed an endlessly useful list item selector, which can adjust based on the input list, and has multiple applications throughout Ladybug and Honeybee. One of the best is for selecting zone-level programs after selecting an overall building program.
Alex Jacobson - Alex also assisted with the coding of the wind speed components.
And, as always, a special thanks goes to all of our awesome users who tested the new components through their several iterations. Special thanks goes to Daniel, Michal, Francisco, and Agus for their continuous support. Thanks again for all the support, great suggestions and comments. We really cannot thank you enough.
Enjoy!,
Ladybug + Honeybee Development Team

uier momento del diseño de un modelo 3D y este se readapta sin necesidad de redibujar la zona alterada.
Otra de las principales características del trabajo paramétrico es que nos permite automatizar procesos de trabajo o diseño. Esto quiere decir que, con procesos sencillos, podemos generar geometrías complejas y siempre justificadas en función de unos parámetros que nosotros definamos; lo que, en cierto modo, elimina la arbitrariedad en el diseño y nos arma de argumentos en la toma de decisiones de proyecto. Por otro lado, se pueden generar texturas y patrones de manera aleatoria o variable en función de atractores.
Tras la realización de este workshop, el alumno será capaz de desarrollar sus propias gramáticas, con la confianza que da comprender los términos básicos de programación sobre los que se apoya todo el sistema de trabajo de Grasshopper.
Grasshopper nos abre todo un mundo de posibilidades en el diseño y en la fabricación digital.
PARA QUIÉN
El workshop está dirigido a estudiantes y profesionales de la arquitectura, el interiorismo, la ingeniería, el diseño de producto, el diseño industrial y, en general, perfiles creativos y disciplinas artísticas que quieran introducirse en el mundo del diseño paramétrico.
Es recomendable tener conocimientos previos de Rhinoceros (nivel básico) ya que hay algunos conceptos que pueden ser útiles para un mejor seguimiento del workshop.

ht spot :)
Is scriptcontext used to define docspace only?scriptcontext is not used only for that. It contains quite some few variables that allow to do different things. For example, there's the sticky dictionary, useful to store temporary information and bring it also across components or over to the _EditPythonScript editor. It is a real module and you can find it in the folder containing also the rhinoscript library.
Not sure how to use these: [...] AddReference('Grasshopper')There is no longer any need to use this call in the last release of GhPython, as the component automatically adds a reference to the Grasshopper library (grasshopper.dll) for convenience. As it might already be clear to you, Python itself does not know about Grasshopper
How is the gh kernel used in relationship to rhinoscript?Not in any specific way. They are two different libraries. The Grasshopper kernel does not know about the ghdoc document, so -- if you ever need to use it -- you can use the rs.coerceXXX() functions to get the geometry from rhinoscript Guids.
>>from Rhino import Geometry as makePlease don't import modules with very-different-looking variable names (aliases). Other people will have more trouble following.
Where can I find documentation on ghenv?Sorry, there is no more documentation than what you can see with autocompletion. However, there is also nothing else there, other than that! We do not encourage modification of Grasshopper behavior via this variable. You can see its sourcecode here:https://github.com/mcneel/ghpython/blob/master/Component/PythonEnvi...The most important information, as you already discovered, is Component, which returns a GH_Component instance (a ZuiPythonComponent instance, to be precise -- but this might change in the future). GH_Component is defined in the Grasshopper SDK.
(Paraphrasing from your comment) Why are these calls doing the same: a = rs.AddPoint(x,y,0) #rhinoscript b = ghdoc.Objects.AddPoint(x,y,0) #rhinoscript? access through ghdoc? how is this different? c = sc.doc.Objects.AddPoint(x,y,0) #only some of the rhinoscript methods availableThese calls are not doing the same. I understand how this might seem difficult, as this is the result of normal OO (object-oriented) design, where you might get reach to the same (or similar) objects through different calls.Now, rs up there is rhinoscriptsyntax module up there.ghdoc is a variable (similar to ghenv) that contains a reference to the invisible Grasshopper document. The document (both Rhino and Grasshopper ones) have an object table available through the Objects attribute. So,sc (the scriptcontext module) has a variable (doc) which gives you whichever document is current. In GhPython, this is by default ghdoc. In Rhino (the _EditPythonScript editor) this is by default Rhino.RhinoDoc.ActiveDoc. This is the place where rhinoscript functions add geometry. Whoever called AddPoint(x,y,0) that way, bypassed standard methods and added geometry through the same call that eventually rhinoscriptsyntax uses. d = Rhino.Geometry.Point3d(x,y,0) #rhinocommon #e is exactly the same as d, just with another shortcut. Dont do this if you can.d invokes the RhinoCommon constructor for Point3d. This returns a 3D point.Use type(var) to get the type of a variable. Other methods exists for other reason (this is IronPython), but please stick to this one unless you know why you should be doing differently.If the first three calls are successful, a, b, c will contain Guids that refer to objects in documents. d will be the RhinoCommon geometric point itself. This has advantages and disadvantage: objects in the document have also attributes like color, linetype, etc, while geometry is completely "bare-bone".
>>got bake figured out on component below.Nice, so you are putting these concepts into practice.
I hope this rather long answer was helpful.Thanks, kind regards,Giulio--Giulio Piacentinofor Robert McNeel & Associatesgiulio@mcneel.com

to prepare walls that extrudes from the base curve and wrap it around to top and bottom slab. To make them nicely, the "walls" have to take into considerations the thickness of the material one is using.
For example, at an exterior 90degrees corner, while some master model makers will try to knife the wall edges into a type of Miter Joint with extreme care and the expense of time. Many will choose make one wall longer while another one shorter and glued with one wall covering another wall. This method proofs to give fairly acceptable result with much less time spent. In my experience of building such models, the challenge is to make calculations and decide which wall have to be shortened and which one have to be lengthened, this applies to both laser cut walls and manually-cut walls. Apart from the fact that this usually a long and boring process, the next step of taking the measurements and redrawing the rectangles (for laser cutting) with the right height and width are prone to human error. The chance of making an mistake is particular high is when facing blocks that have non-90degrees corners.
Here I have created a small tool that reads polyline curves and automatically determine the required shortening and lengthening on all walls, taking care of the material thickness. It reads the height value from the Name of the polyline curve (which I found easiest to use). It can then redraw the laser cutting files for the walls with correct tags that allow assembly much easier. I also wrote a 3D extruded preview of all the models, so that one can check visually before going to the cutting, which also helps during the assembly to figure out which wall overlaps with which wall and how to properly glue them.
To run the script, you need to have "planar" "closed" polylines (it wont accept curve segments) with the height value entered in the "Name Property". (look at my example file)
If you have changed the height of the building but the script did not update, press F5 in grasshopper to Recompute.
Each block is named in numerical order, the walls are tagged with alphabetical suffix to specify the sequence.
Top slab has no tag to avoid showing on the model, match them with the bottom slab if you get confused.
Note that the walls are individual piece but not a folding sheet. The whole idea is not for models that the walls warps (continuous piece of paper) around top and bottom plates.
I have added an etched line for positioning the roof with a slight sink. Which will make the blocking look nicer with a shadow gap.
The script with an example file is uploaded on my website here: http://www.dreamationworks.com/?p=684

If you want to jump straight in, you can download the latest build from the Firefly website or from Food4Rhino project page. Or, if you'd rather learn more about all the new features, keep reading!
Improved Arduino Support The Firefly Firmata (Arduino Sketch) has gone through a massive overhaul - making it much more compact, efficient, and extensible. The sketch is now just over 230 lines of code (compared to more than 500 in the previous version). But more importantly, the firmata is now more extensible; making it easier to add support for new Arduino boards... Like what you ask? Well, support for the new Arduino Due platform for example. The Arduino Due is an advanced board and while it may look similar to the Arduino Mega... it's actually quite different under the hood. It features an ARM Cortex-M3 CPU which means its really fast. It also features 12-bit analog resolution for reading and writing (which is pretty awesome). As I said, the Due is a more advanced board and it does require some caution when getting started. You can find out more about the Due platform at the Arduino Due Getting Started page.
One of the biggest changes with the revision of the Firmata was that it required some structural changes with how the data is sent/received from Grasshopper. So, if you are planning on using the latest version of the Firmata, you'll need to also have the latest Firefly components installed as well. This shouldn't be an issue because the installer will place the new Firefly Firmata in your sketchbook folder and install the new components as well... but it's worth noting so you don't try to mix and match the versions.
Kinect Version 2 Support Earlier this summer, Microsoft released a new and improved version of its popular Kinect motion tracking sensor. The sensor includes better body, hand, and joint orientation, 1080p color video (1920x1080), depth video (512x424), and a new active infrared video (512x424). The sensor now has the capability to track up to 6 people at once (compared to only two people with the previous version).
This build of Firefly now comes with three new components to work with this new sensor. The Video Stream can access the color, depth, and infrared video streams at different resolutions. Simply right-click on the video component to choose the video feed and resolution. Note: You may need to update your graphics card in order to get the infrared video stream to work properly (at least I did before it began working properly). The Skeleton Tracker is similar to the previous version, but can now track up to 6 people. And the Mesh Reconstruction component will build a fully colored 3D mesh using the color and depth data from the sensor. I plan to add more components to this section soon, but I wanted to go ahead and release this so more people could use it! [EDIT: I would like to thank Panagiotis Michalatos for his collaboration in the development of the Kinect V2 tools].
New Computer Vision Tools This release also includes a number of new computer vision tools. One component to note is the Bitmap Tracer, which can be seen in action here. The Bitmap Tracer component spawns a number of randomly generated particles which trace the edges of a bitmap using the nearest contouring vector. Another pair of components is the Bitmap Decompose/Recompose which can either decompose or reconstruct a bitmap using a list of values for its constituent channels. These two can be used together to swap channels in an image (think chroma keying). There's also a Bitmap Threshold component which uses the average dithering algorithm to find the color quantization of an image. Lastly, I've updated the Leap Motion Finger Tracking component to work with the latest release of the Leap v2.2.1 software release. The component now has improved finger tracking including joint and bone position/orientation.
In addition to these new features, there's also a number of bug fixes too (check out the readme if your interested). As always, I welcome any and all feedback on this build. Your support really helps, so please let me know what you think!…
