oftware connections built from the initial seed of the project. As always you can download the new release from Food4Rhino. Make sure to remove the older version of Ladybug and Honeybee and update your scripts.
This release is also special since today it is just about 3 years (3 years and 2 weeks) from the first release of Ladybug. As with any release, there have been a number of bug fixes and improvements but we also have some major news this time. In no specific order and to ensure that the biggest developments do not get lost in the extensive list of updates, here are the major ones:
Mostapha is re-writing Ladybug!
Ladybug for DynamoBIM is finally available.
Chris made bakeIt really useful by incorporating an export pathway to PDFs and vector-based programs.
Honeybee is now connected to THERM and the LBNL suite thanks to Chris Mackey.
Sarith has addressed a much-desired wish for Honeybee (Hi Theodore!) by adding components to model electric lighting with Radiance.
Djordje is on his way to making renewable energy deeply integrated with Ladybug by releasing components for modeling solar hot water.
There is new bug. Check the bottom of the post for Dragonfly!
Last but definitely not least (in case you’re not still convinced that this release is a major one) Miguel has started a new project that brings some of Ladybug’s features directly to Rhino. We mean Rhino Rhino - A Rhino plugin! Say hi to Icarus! #surprise
Before we forget! Ladybug and Honeybee now have official stickers. Yes! We know about T-Shirts and mugs and they will be next. For now, you can deck-out your laptops and powerhouse simulation machines with the symbology of our collaborative software ecosystem.
Now go grab a cup of tea/coffee and read the details below:
Rewriting Ladybug!
Perhaps the most far-reaching development of the last 4 months is an effort on the part of Mostapha to initiate a well structured, well documented, flexible, and extendable version of the Ladybug libraries. While such code is something that few community members will interact with directly, a well-documented library is critical for maintaining the project, adding new features, and for porting Ladybug to other software platforms.
The new Ladybug libraries are still under development across a number of new repositories and they separate a ladybug-core, which includes epw parsing and all non-geometric functions, from interface-specific geometry libraries. This allows us to easily extend Ladybug to other platforms with a different geometry library for each platform (ie. ladybug-grasshopper, ladybug-dynamo, ladybug-web, etc) all of which are developed on top of the ladybug-core.
Without getting too technical, here is an example of a useful outcome of this development. If you want to know the number of hours that relative humidity is more than 90% for a given epw, all that you have to code (in any python interface) is the following:
import ladybug as lb
_epwFile = r"C:\EnergyPlusV7-2-0\WeatherData\USA_CO_Golden-NREL.724666_TMY3.epw"
epwfile = lb.epw.EPW(_epwFile)
filteredData = epwfile.relativeHumidity.filterByConditionalStatement('x>90')
print "Number of hours with Humidity more than 90 is %d "%len(filteredData.timeStamps)
Compare that to the 500 + lines that you would have had to write previously for this operation, which were usually tied to a single interface! Now let’s see what will happen if you want to use the geometry-specific libraries. Let’s draw a sunpath in Grasshopper:
import ladybuggrasshopper.epw as epw
import ladybuggrasshopper.sunpath as sunpath
# get location data form epw file
location = epw.EPW(_epwFile).location
# initiate sunpath based on location
sp = sunpath.Sunpath.fromLocation(location, northAngle = 0, daylightSavingPeriod = None, basePoint =cenPt, scale = scale, sunScale = sunScale)
# draw sunpath geometry
sp.drawAnnualSunpath()
# assign geometries to outputs
...
Finally we ask, how would this code will look if we wanted to make a sunpath for dynamo? Well, it will be exactly the same! Just change ladybuggrasshopper in the second line to ladybugdynamo! Here is the code which is creating the sunpath below.
With this ease of scripting, we hope to involve more of our community members in our development and make it easy for others to use ladybug in their various preferred applications. By the next release, we will produce an API documentation (documentation of all the ladybug classes, methods and properties that you can script with) and begin making tutorials for those interested in getting deeper into Ladybug development.
LADYBUG
1 - Initial Release of Ladybug for Dynamo:
As is evident from the post above, we are happy to announce the first release of Ladybug for Dynamo! You can download the ladybug package from Dynamo package manager. Make sure to download version 0.0.6 which is actually 0.0.1! It took a number of trial and errors to get it up there. Once you have the file downloaded you can watch these videos to get started:
The source code can be find under ladybug-dynamo repository and (as you can already guess) it is using the new code base. It includes a very small toolkit of essential Ladybug components/nodes but it has enough to get you started. You can import weather files, draw sunpaths and run sunlighthours or radiation analyses.
There are two known issues in this release but neither of them is critical. You need to have Dynamo 0.9.1 or higher installed which you can download from here (http://dynamobuilds.com/). It is recommended that you run the scripts with ‘Manual’ run (as opposed to ‘Automatic’) since the more intense calculations can make Dynamo crash in automatic mode.
To put things in perspective, here is how we would map Ladybug for Dynamo vs Ladybug and Honeybee for Grasshopper on the classic ‘Hype graph’. The good news is that what we learned a lot from the last three years, making development of the Dynamo version easier and getting us to the plateau of productivity faster.
We should also note that the current development of the Dynamo interface is behind that of the Ladybug-Core, which means there are a number of features that are developed in the code but haven’t made their way to the nodes yet. They will be added gradually over the next month or two.
If you’re interested to get involved in the development process or have ideas for the development, follow ladybug on Facebook, Twitter and Github. We will only post major release news here. Facebook, github and twitter will be the main channels for posting the development process. There will also be a release of a new ladybug for Grasshopper soon that will use the came Ladybug-Core libraries as the Dynamo interface [Trying hard not to name it as Ladybug 2].
2 - New Project “Icarus” Provides Ladybug Capabilities Directly in Rhino
Speaking of expanded cross-platform capabilities, the talented Miguel Rus has produced a standalone Rhino Plugin off of the original Ladybug code that has been included in this release. After writing his own core C# libraries, Miguel’s plugin enables users to produce sunpath and run sunlight hours analyses in the Rhino scene without need of opening Grasshopper or engaging the (sometimes daunting) act of visual scripting.
This release includes his initial RHP plugin file. It is hoped that Miguel’s efforts will extend some of the capabilities of environmental design to individuals who are unfamiliar with visual scripting, casting the network of our community into new territory. We need your help spreading the word about Icarus since the people who will benefit the most from it have probably not read this far into the release notes. Also, as the project is in the early stages, your feedback can make a great difference. You can download the current release from this link.
Once you download the zip file. Right click and unblock it. Then extract the files under C:\Program Files\Rhinoceros 5 (64-bit)\Plug-ins\ folder. Drag and drop the RHP file into Rhino and you should be ready to go. You can either type Icarus in the command line or open it via the panels. Here is a short video that shows how to run a sunlighhours analysis study in Rhino.
3 - BakeIt Input Now Supports a Pathway to PDF +Vector Programs
As promised in the previous release, the BakeIt_ option available on Ladybug’s visual components has been enhanced to provide a full pathway to vector-based programs (like Illustrator and Inkscape) and eases the export to vector formats like PDFs.
This means that the BakeIt_ operation now places all text in the Rhino scene as actual editable text (not meshes) and any colored meshes are output as groups of colored hatches (so that they appear as color-filled polygons in vector-based programs). There is still an option to bake the colored geometries as light meshes (which requires smaller amounts of memory and computation time) but the new hatched capability should make it easier to incorporate Ladybug graphics in architectural drawings and documents like this vector psychrometric chart.
4 - Physiological Equivalent Temperature (PET) Now Available
Thanks to the efforts of Djordje Spasic, it is now possible to compute the common outdoor comfort metric ‘Physiological Equivalent Temperature’ (PET) with Ladybug. The capability has been included with this release of “Thermal Comfort Indices” component and is supported by a “Body Characteristics” component in the Extra tab. PET is particularly helpful for evaluating outdoor comfort at a high spatial resolution and so the next Honeybee release will include an option for PET with the microclimate map workflow.
5 - Solar Hot Water Components Available in WIP
Chengchu Yan and Djordje Spasic have built a set of components that perform detailed estimates of solar hot water. The components are currently undergoing final stages of testing and are available in the WIP tab of this release. You can read the full release notes for the components here.
6 - New Ladybug Graphic Standards
With the parallel efforts or so many developers, we have made an effort in this release to standardize the means by which you interact with the components. This includes warnings for missing inputs and the ability to make either icons or text appear on the components as you wish (Hi Andres!). A full list of all graphic standards can be found here. If you have any thoughts or comments on the new standards, feel free to voice them here.
7 - Wet Bulb Temperature Now Available
Thanks to Antonello Di Nunzio - the newest member of the Ladybug development team, it is now possible to calculate wet bulb temperature with Ladybug. Antonello’s component can be found under the WIP tab and takes inputs of dry bulb temperature, relative humidity, and barometric pressure.
8 - New View Analysis Types
The view analysis component now allows for several different view studies in addition to the previous ‘view to test points.’ These include, skyview (which is helpful for studies of outdoor micro-climate), as well as spherical view and ‘cone of vision’ view, which are helpful for indoor studies evaluating the overall visual connection to the outdoors.
HONEYBEE
1 - Connection to THERM and LBNL Programs
With this release, many of you will notice that a new tab has been added to Honeybee. The tab “11 | THERM” includes 7 new components that enable you to export ready-to-simulate Lawrence Berkeley National Lab (LBNL) THERM files from Rhino/Grasshopper. THERM is a 2D finite element heat flow engine that is used to evaluate the performance of wall/window construction details by simulating thermal bridging behavior. The new Honeybee tab represents the first ever CAD plugin interface for THERM, which has been in demand since the first release of LBNL THERM several years ago. The export workflow involves the drawing of window/wall construction details in Rhino and the assigning of materials and boundary conditions in Grasshopper to produce ready-to-simulate THERM files that allow you to bypass the limited drawing interface of THERM completely. Additional components in the “11 | THERM” tab allow you to import the results of THERM simulations back into Grasshopper and assist with incorporating THERM results into Honeybee EnergyPlus simulations. Finally, two components assist with a connection to LBNL WINDOW for advanced modeling of Glazing constructions. Example files illustrating many of the capabilities of the new components can be found in there links.
THERM_Export_Workflow, THERM_Comparison_of_Stud_Wall_Constructions
Analyze_THERM_Results, Thermal_Bridging_with_THERM_and_EnergyPlus
Import_Glazing_System_from_LBNL_WINDOW, Import_LBNL_WINDOW_Glazing_Assembly_for_EnergyPlus
It is recommended that those who are using these THERM components for the first time begin by exploring this example file.
Tutorial videos on how to use the components will be posted soon. A great deal of thanks is due to the LBNL team that was responsive to questions at the start of the development and special thanks goes to Payette Architects, which allowed Chris Mackey (the author of the components) a significant amount of paid time to develop them.
2 - Electrical Lighting Components with Enhanced Capabilities for Importing and Manipulating IES Files
Thanks to the efforts of Sarith Subramaniam, it is now much easier and more flexible to include electric lighting in Honeybee Radiance simulations. A series of very exciting images and videos can be found in his release post.
You can find the components under WIP tab. Sarith is looking for feedback and wishes. Please give them a try and let him know your thoughts. Several example files showing how to use the components can be found here. 1, 2, 3.
3- Expanded Dynamic Shade Capabilities
After great demand, it is now possible to assign several different types of control strategies for interior blinds and shades for EnergyPlus simulations. Control thresholds range from zone temperature, to zone cooling load, to radiation on windows, to many combinations of these variables. The new component also features the ability to run EnergyPlus simulations with electrochromic glazing. An example file showing many of the new capabilities can be found here.
Dragonfly Beta
In order to link the capabilities of Ladybug + Honeybee to a wider range of climatic data sets and analytical tools, a new insect has been initiated under the name of Dragonfly. While the Dragonfly components are not included with the download of this release, the most recent version can be downloaded here. An example file showing how to use Dragonfly to warp EPW data to account for urban heat island effect can also be found here. By the next release, the capabilities of Dragonfly should be robust enough for it to fly on its own. Additional features that will be implemented in the next few months include importing thermal satellite image data to Rhino/GH as well as the ability to warp EPW files to account for climate change projections. Anyone interested in testing out the new insect should feel free to contact Chris Mackey.
And finally, it is with great pleasure that we welcome Sarith and Antonello to the team. As mentioned in the above release notes, Sarith has added a robust implementation for electric light modeling with Honeybee and Antonello has added a component to calculate wet bulb temperature while providing stellar support to a number of people here on the GH forum.
As always let us know your comments and suggestions.
Enjoy!
Ladybug+Honeybee development team
PS: Special thanks to Chris for writing most of the release notes!…
her people) a tremendous amount of time creating them by hand. Dog Treat was far from perfect, however it was good enough to use almost daily.
Three years is a long time. Since 2016 my Gh knowledge has expanded and I’ve seen how dodgy some of the scripting is. With this in mind I started work on a new build. Many things have been tweaked and some things have been rebuilt from the ground up.
Everything has been designed to be leaner and be a general solution to the problem of creating dog bone corners on geometry for quick, efficient and safe CNC fabrication.
Some of these things are:
Adding prompts about user geometry to make them aware about open curves, varying curve heights and if their geometry had been altered (mostly removing unnecessary points on curves).
Smooth Transfers. If you’re in a rush and need to speed through cutting, smooth transfers mean that a lead in geometry is now created alongside the actual dog bone arc. This means the router bit doesn’t have to come to a minute stop at every corner. This is turned on by default.
Acute Angle Condition If the angle between the two curves adjacent to a dog bone point is acute, previously the dog bone corner was useless. This was because the distance between the end points of the dog bone arc were less than the diameter of the router bit. There are many ways this condition could be addressed. I chose to circumscribe a larger arc based on the original angle between the adjacent curves. While it removes more material from the corner, it minimises tool wear and any potential for material to burn.
Single Curve A single curve can now be input into Dog Treat. It will be output with both internal and external treatments.
I’ll continue to update Dog Treat as the need arises, it’s become somewhat of a hobby now. Maybe one day it will become part of a Plug-in… once I learn to code it though!
Happy Treating!
Hi Everyone,
Here's a tool I've been working on for the past 4 months or so in my free time. It's a dog bone corner generator, however it's a little different to some of the existing ones. It's designed to be used for large amounts of geometry and as such, it avoids using any curve boolean operations that are computationally taxing. You don't have to split your curves up into internal and external lots either, it works it all out so you can be lazy. I've also incorporated Lunch Box's Object Bake Component for a one click operation that bakes geometry back out to Internal and External profile layers.
Let me know how it goes, will update where necessary.
Best,
Darcy

and export the geometry out to VVVV to render it LIVE! RawRRRR. In this case, a digital audio workstation Ableton Live, a leading industrial standard in contemporary music production.
the good news is that VVVV and ableton live lite is both free.
https://www.ableton.com/en/products/live-lite/
i am not trying to use ipad as a controller for grasshoppper. I wanted to work with a timeline (similar to MAYA or Ableton or any other DAW(digital audio workstation)) inside grasshopper in an intuitive way. Currently there is no way of SEQUENCING your definition the way you want to see that i know of.
no more combersome export import workflows... i dont need hyperrealistic renderings most of the time. so much time invested in googling the right way to import, export ... mesh settings...this workflow works for some, for some not ...that workflow works if ... and still you cannot render it live nor change sequence of instruction WHILE THE VIDEO is played. and I think no one wants to present rhinoceros viewport. BUT vvvv veiwport is different. it is used for VJing and many custom audio visual installation for events, done professionally. you can see an example of how sound and visuals come together from this post, using only VVVV and ableton. http://vvvv.org/documentation/meso-amstel-pulse
I propose a NEW method. make a definition, wire it to ableton, draw in some midi notes, and see it thru VVVV LIVE while you sequence the animation the WAY YOU WANT TO BE SEEN DURING YOUR PRESENTATION FROM THE BEGINNING, make a whole set of sequences in ableton, go back change some notes in ableton and the whole sequence will change RIGHT INFRONT of you. yes, you can just add some sound anywhere in the process. or take the sound waves (sqaure, saw, whateve) or take the audio and influence geometric parameters using custom patches via vvvv. I cannot even begin to tell you how sophisticated digital audio sound design technology got last ten year.. this is just one example which isn't even that advanced in todays standard in sound design ( and the famous producers would say its not about the tools at all.) http://www.youtube.com/watch?v=Iwz32bEgV8o
I just want to point out that grasshopper shares the same interface with VVVV (1998) and maxforlive, a plug in inside ableton. audio mulch is yet another one that shares this interface of plugging components to each other and allows users to create their own sound instruments. vvvv is built based on vb, i believe.
so current wish list is ...
1) grasshopper recieves a sequence of commands from ableton DONE
thanks to sebastian's OSCglue vvvv patch and this one http://vvvv.org/contribution/vvvv-and-grasshopper-demo-with-ghowl-udp
after this is done, its a matter of trimming and splitting the incoming string.
2) translate numeric oscillation from ableton to change GH values
video below shows what the controll interface of both values (numbers) and the midi notes look like.
https://vimeo.com/19743303
3) midi note in = toggle GH component (this one could be tricky)
for this... i am thinking it would be great if ...it is possible to make "midi learn" function in grasshopper where one can DROP IN A COMPONENT LIKE GALAPAGOS OR TIMER and assign the component to a signal in, in this case a midi note. there are total 128 midi notes (http://www.midimountain.com/midi/midi_note_numbers.html) and this is only for one channel. there are infinite channels in ableton. I usually use 16.
I have already figured out a way to send string into grasshopper from ableton live. but problem is, how for grasshopper to listen, not just take it in, and interpret midi and cc value changes ( usually runs from 0 to 128) and perform certain actions.
Basically what I am trying to achieve is this : some time passes then a parameter is set to change from value 0 to 50, for example. then some time passes again, then another parameter becomes "previewed", then baked. I have seen some examples of hoopsnake but I couldn't tell that you can really control the values in a clear x and y graph where x is time and y is the value. but this woud be considered a basic feature of modulation and automation in music production. NVM, its been DONE by Mr Heumann. https://vimeo.com/39730831
4) send points, lines, surfaces and meshes back out to VVVV
5) render it using VVVV and play with enormous collection of components in VVVV..its been around since 1998 for the sake of awesomeness.
this kind of a digital operation-hardware connection is usually whats done in digital music production solutions. I did look into midi controller - grasshopper work, and I know its been done, but that has obvious limitations of not being precise. and it only takes 0 o 128. I am thinking that midi can be useful for this because then I can program very precise and complex sequence with ease from music production software like ableton live.
This is an ongoing design research for a performative exhibition due in Bochum, Germany, this January. I will post definition if I get somewhere. A good place to start for me is the nesting sliders by Monique . http://www.grasshopper3d.com/forum/topics/nesting-sliders
…
n be obtained for curved NURBS surfaces as well as unconventional window configurations".
And I also noticed the following information form the optional input in the runEnergySimulation component.
"meshSettings_: Optional mesh settings for your geometry from any one of the native Grasshopper mesh setting components. These will be used to change the meshing of curved surfaces before they are run through EnergyPlus (note that meshing of curved surfaces is done since Energyplus is not able to calculate heat flow through non-planar surfaces). Default Grasshopper meshing is used if nothing is input here but you may want to decrease your calculation time by changing it to Coarse or increase your curvature definition (and calculation time) by making it finer".
1) My case is an one-story, rectangular-plan large hall (40m*70m*25m) with a curved roof. The roof surface is a part of a standard sphere and the walls and floor are all planar (the each wall has one curved edge as showed in the image).
For testing, I threw the original curved roof surface into daylight and energy simulations without making customized meshings, because I assumed that it might be automatically converted to meshs by Honeybee - Am I right? As showed in the image, how can I reduce the number of meshs in a proper way? Must two connected surfaces (i.e. wall and roof) be STRICTLY/SEAMLESSLY connected or not (considering different divisions of meshs in the respective surface)? - Is a connection tolerance allowed?
2) But, when I run the annual daylight simulation for this case, it gave me a lot of warnings "oconv: warning - zero area for polygon".- is that normal? and how to avoid this? Does the daylight simulation allow "curved NURBS surfaces"?
3) Moreover, when I run an energy simulation for this case, it costed extremely long time. It was just so long that I did not even have results out of one simulation. - I guessed it might be the problem caused by the curved roof surface (or automatic meshing?), but I don't have experience of converting a curved NURBS/spheral surface into correct meshs that can be recognized by Honeybee simulations (Daylight and Energy) in a proper way.
4) The large window on the wall was generated by the "_glzRatio". But the automatically generated wall meshs around this window are just too "fine", which might largely increase simulation time. Is there a proper way to get rid of it? (Considering that the size, shape and position of the window will have large influence on the daylight distribution in the building, it is worthy to keep the size, shape and position of the window as it should be in reality).
In sum, considering all above, could your please provide me some suggestions/tutorials/links that might be helpful for dealing with "curved NURBS surfaces" in Honeybee simulations.
Thank you all in advance!
Best,
Ding

t. So here we go!
1. Honeybee is brown and not yellow [stupid!]...
As you probably remember Honeybee logo was initially yellow because of my ignorance about Honeybees. With the help of our Honeybee expert, Michalina, now the color is corrected. I promised her to update everyone about this. Below are photos of her working on the honeybee logo and the results of her study.
If you think I'm exaggerating by calling her a honeybee expert you better watch this video:
Thank you Michalina for the great work! :). I corrected the colors. No yellow anymore. The only yellow arrows represent sun rays and not the honeybee!
2. Yellow or brown, W[here]TH Honeybee is?
I know. It has been a long time after I posted the initial video and it is not fun at all to wait for a long time. Here is the good news. If you are following the Facebook page you probably now that the Daylighting components are almost ready.
Couple of friends from Grasshopper community and RADIANCE community has been helping me with testing/debugging the components. I still think/hope to release the daylighting components at some point in January before Ladybug gets one year old.
There have been multiple changes. I finally feel that the current version of Honeybee is simple enough for non-expert users to start running initial studies and flexible enough for advanced users to run advanced studies. I will post a video soon and walk you through different components.
I think I still need more time to modify the energy simulation components so they are not going to be part of the next release. Unfortunately, there are so many ways to set up and run a wrong energy simulation and I really don’t want to add one new GIGO app to the world of simulation. We already have enough of that. Moreover I’m still not quite happy with the workflow. Please bear with me for few more months and then we can all celebrate!
I recently tested the idea of connecting Grasshopper to OpenStudio by using OpenStudio API successfully. If nothing else, I really want to release the EnergyPlus components so I can concentrate on Grasshopper > OpenStudio development which I personally think is the best approach.
3. What about wind analysis?
I have been asked multiple times that if Ladybug will have a component for wind study. The short answer is YES! I have been working with EFRI-PULSE project during the last year to develop a free and open source web-based CFD simulation platform for outdoor analysis.
We had a very good progress so far and our rockstar Stefan recently presented the results of the work at the American Physical Society’s 66th annual DFD meeting and the results looks pretty convincing in comparison to measured data. Here is an image from the presentation. All the credits go to Stefan Gracik and EFRI-PULSE project.
The project will go live at some point next year and after that I will release the Butterfly which will let you prepare the model for the CFD simulation and send it to EFRI-PULSE project. I haven’t tried to run the simulations locally yet but I’m considering that as a further development. Here is how the component and the logo looks like right now.
4. Teaching resources
It has been almost 11 months from the first public release of Ladybug. I know that I didn't do a good job in providing enough tutorials/teaching materials and I know that I won’t be able to put something comprehensive together soon.
Fortunately, ladybug has been flying in multiple schools during the last year. Several design, engineering and consultant firms are using it and it has been thought in several workshops. As I checked with multiple of you, almost everyone told me that they will be happy to share their teaching materials; hence I started the teaching resources page. Please share your materials on the page. They can be in any format and any language. Thanks in advance!
I hope you enjoyed/are enjoying/will enjoy the longest night of the year. Happy Yalda!
Cheers,
-Mostapha

y anyway ;))
Since 2014 i begun to get back into the construction biz for some dozen main reasons, one of them being the highly increased availability of this kind of software "power", and robotics.
first project ended by 1stQ 2015 was focused on the development of a parametric block for construction. (almost sure the first parametric product designed in Uruguay, and probably one of the few first of this kind globally...)
Far from being a complicated model. In fact the standard model is extremely simple, key thing is that is fully parametric...
dimensions, materials, textures, colors... and so on
second key thing is that the main common component of the blocks (an EPS core) is robotically machined...
the blocks are the base of a construction system (oriented mainly - though not restricted only - to residential buildings) that
- is based on digital models, tendentially to be used in parametric models of buidings
- lab tested to prove to be 1.5 times as compression resistant than traditional bricks and blocks. (autoportability up to two stories buildings)
- has recently proved (due to size) to be 300% more efficient than the classic and 200% more efficient than steel frame in (our country official figures)
check it out here

https://drive.google.com/file/d/0B1TRxxgF_sEnQnZrTkZGbUx3cmM/view
--
- and it's aimed to be mass produced and handled by robots...
this project ended on 1H 2016
and i filed 4 patents in the process.
3 of them of mechanical devices designed as extensions for a cnc machine i own
and the fourth (
the patent related specifically with the blocks ) included a dozen of innovations (believe me...i have almost 15 yrs in the biz, and are coool stuff...)
along the project I've been working with inventor, even knowing in advance it will lack the kind of features I wanted to program many things... (lisp, VB, etc.... all same species of -prehistoric - animals) to leverage the tool to the sky - and far beyond... -
but was an alternative valid by that time because it allows the implementation of some form of parametric models, had a local representative and some supposedly skilled guys in the neibourhood....
but life is hard... and none of the latter two rendered me any significant help
so I had to take the tour myself...
- mind i never regret to do things that others cant -
and finish what i start
this one was a great project for many figures... and ended with more results than the ones commited to accomplish...
... some more history here ....
then because of a customer who brought a ZHA project ! to quote..., I crossed with rhino, and then met GH again to notice to my great joy and pleasure, in what kind of animal it had developed...
since money talks I'm investing hard on getting up to the expectations, and beyond as i usually do...
and thats how we met..
2017-2018 it's the time frame to build two robots. first one is a prototype to handle the k-nano blocks in the production process, delivery AND at the construction site ( a "smart crane" we nicknamed...)
the other one is the first prototype of robot to assist in the fabrication (smart blocker we called it to be creative ! ;))
then by 2018-2019 i'll be making a "kinda contour crafter" machine to complete the pie :) (you'll be interested on this..)
i guess you already know what all this has to do with GH...
i already have all the components i can imagine to do almost all i ever wanted to do in relation to this set of projects
but in almost a single tool !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
i can design, animate, render, optimize, simulate and even robotic simulate..
so, i have to ask...
is there a chance you might be interested in helping us in some projects we are starting on march and june 2017 (8 and no more than 18 months of duration respectively) ?
sent you a friend request, for the case you might be interested to continue by e-mail...
in any case many thanks for your help and inspiration !
best regards !
long happy marriage, and large figures bank account !

The paper depicts a framework for optimizing passive performance by exploring elements such as geometry, building orientation, fenestration configurations, and shading devices in response to particular program requirements, site-specific constraints, and climate conditions.
ASHRAE 90.1 was used as compliant reference model for four different climate zones, incorporating real sites and urban overshadowing conditions. The results showed improvements within a range of 4% to 17% in Energy Use Intensity reduction, while improving daylighting within a range of 27% to 65%, depending on the location and climate.
Overall, the framework provide guidance to make more informed decisions in early-stages of design, where as many know, the impacts can be the greatest.

Intersect Shouldn't Punt When Encountering Areas of Intersection
Several posts talk about how Booleans are really just shortcut implementations of the Intersect/Trim/Split/Join (ITSJ) design pattern. Agreed. I realized this when trying to understand and resolve my first Boolean related problem. So when I broken down my characterization to the 4 component steps, I found is that it was the Intersect operation that was generating an erroneous (read: incomplete) set of intersection curves. I posted my findings along with a possible solution in an email to McNeel tech support and in this Rhino discussion an edited version of which I’ve quoted again below. But the only response I received from McNeel was that I shouldn't expect any changes in the product that improves Booleans.
The unexpected behavior I've been having with Rhino, and by extension Grasshopper, is that the current implementation of the Rhino Intersect command is generating an incomplete network of curves when given 2 surfaces having regions that are (almost) coincident. When Intersect determines that there's no single curve able to represent the intersection in those areas, but rather an area of intersection, Intersect erroneously doesn't generate any curve to represent that portion of the intersection — which is mathematically incorrect. This decision to "punt" in these situations renders the generated results to not be useful for subsequent steps of the ITSJ design pattern. Rather than not including these areas of intersection in the network of curves, Intersect should generate any non-kinky, non-looping curve(s) through a region of intersection that connects with all other intersection curves adjacent to the region. Any valid curve is far more useful — and mathematically correct — than no curve through these regions.
Informative and Detailed Error Reporting Will Save Users’ Time
A number of users feel as I do that the error information available when an operation fails is insufficient.
The Rhino Learning Curve Is Fractally Steep
While some responses have suggested that I’m just too new to Rhino, a number of long-time Rhino users have said that they are continually “learning” the product's idiosyncrasies, and expect that they will never really know what the product will do every time. What they’ve learned from their years of experience is how to hack their designs to work around Rhino’s quirks.
I conclude from these stories that, sure, I’m green, but that I, all of us, are destine to be forever “green” because the current development methodology results in a product that can never really be understood.
Wow.
In his reply above @Paul N Jeffies said…
One thing that's important to understand when using Rhino for this kind of thing is that Rhino does not have a particularly meaningful conception of a 'solid object' - solids are defined simply as a collection of (infinitely thin) NURBS surfaces joined together with no gaps between. That's part of the reason for the problems with booleans in Rhino, but it also means that you don't really need boolean operations since you can do everything by exploding the polysurface and using the Intersect/Trim/Split commands on the individual surfaces to build up the boundary surfaces you want, then rejoin into a solid afterwards.
As a software architect with ~40 years of tech experience, I would again suggest that the root cause of the product's unknowability is the lack of rigor so far exhibited in defining the layers of abstraction. If proper rigor were applied, then, from a user’s perspective, a solid really would be a solid. The proper way to reduce a solid to a set of adjacent surfaces would be to use a function like ExplodeSolid, and to get a set of curves from a surface we would have to use ExplodeSurface, and so on. So rigor doesn’t prohibit users from pulling back the curtain, but rather empowers the core development team to enforce encapsulation at the current layer of abstraction — whether point, curve, surface, solid, or whatever.
The Solution Begins With Changing The Conversation
With all this said, I don’t believe that Rhino is fatally flawed or impossible to fix. I also don't believe that the resulting loss of productivity is the users' fault. I do believe though that the first step is for all, McNeel and users, to name the condition, raise this as a high priority, work collaboratively to define a corrected abstraction stack, and add appropriate rigor to the implementation of the next major release.
About a month ago I spent about 1/2 hour searching through the Rhino discussions for topics related to The Boolean Problem. I found literally 100's of posting, with many noops like I am now saying they were giving up and going to another tool because Rhino’s learning curve was too steep. Yes, filleting and trimming are two other big Rhino problems that I believe have similar roots. Yet I wonder whether these deep-seated challenges could, in fact, be overcome — by first changing the conversation.
I’d again ask what other, more experienced users think.

rm. Im guessing this is not what is referred to as a "plug in".
I can access and retrieve an existing Rhino application object, or create a new one, from my form. However, when I try to interact with Rhino in any any way through using my own functions defined in a class library (.dll), and using fucntions stored in the RMA library, I keep hitting a brick wall. I just cant get it to work.
As a test, see code below, I have a console application that is calling a Class1 object (referenced as an extenal dll) that simply assigns a value to the x property of this object. Im usng the On3Dpoint object.
This simple instruciton causes an error message that is being duplicated in my more complicated project. I belive the Rhino_DOTNET.dll is up to date. Im targeting the .NET 2.0 frame work. Using Rhino 4, SR8. Note this is a very basic test just to see if it is the reference/compiler/other settings that are causing the probelm. Im not interacting directly with Rhino, just testing to see if I can call functions from the referenced RMA libraries etc. It appears I cant :(
This is the class1 code:
Public Class Class1
Sub test()
Dim oPt As New RMA.OpenNURBS.On3dPoint
oPt.x = 10
Dim btest As Boolean = False
End Sub
End Class
This is the console code
Module Module1
Sub Main()
Dim oClass As New Class1
oClass.test()
Dim bTest As Boolean = False
End Sub
End Module
The error message I get is
Could not load file or assembly 'Rhino_DotNet, Version=4.0.61206.14, Culture=neutral, PublicKeyToken=552281e97c755530' or one of its dependencies. An attempt was made to load a program with an incorrect format.
HELP!!!
