the river Plate is an unexplored opportunity. The grid that configures the city’s urban tissue remains oblivious to its context, imposing a constant order. Its relationship with the river is one of mutual exclusion; as soon as the grid reaches the river it stops, but never modifies its nature. There is one happy exception to this condition – the northern riverside area of Buenos Aires called ‘Tigre’, which responds to the topography of the natural delta. In this workshop, projects will embrace the boundary between river and city as a means of managing alternative metropolitan ecosystems. By challenging the traditional relationship between architectural, urban and natural forces, students will propose new territorial organisations that develop both floating and rooted structures that are responsive to the nature of the delta. In this research workshop students have the opportunity to develop a range of computational techniques in order to explore alternative design opportunities. Week 1 Organised in teams, students will work with the articulation of the grid and the river. The goal is to produce several iterations analysing the potential transformation of the grid as it reaches the riverbank. This analysis will form the basis of an urban design proposal that establishes a new relationship between the city and the river. Design tutors, including Victor Orive, Arturo Revilla and professionals from the A A and other institutions, will provide digital tutorials and lectures on their own urban design research and projects. Week 2 During this phase we will address how such conditions affect discrete objects and/or a field of objects. The goal is to design a pavilion and study how a gradual change in field conditions will affect its size, porosity and orientation. This will unfold new opportunities to redefine the relationship between form and function.

nts for Ladybug too. They are based on PVWatts v1 online calculator, supporting crystalline silicon fixed tilt photovoltaics.
You can download them from here, or use the Update Ladbybug component instead. If you take the first option, after downloading check if .ghuser files are blocked (right click -> "Properties" and select "Unblock").
You can download the example files from here.
Video tutorials will follow in the coming period.
In the very essence these components help you answer the question: "How much energy can my roof, building facade, solar parking... generate if I would populate them with PV panels"?
They allow definition of different types of losses (snow, age, shading...) which may affect your PV system:
And can find its optimal tilt and orientation:
Or analyse its performance, energy value, consumption, emissions...

The exhibition started on May 12th and will be presented until August 19th 2012.
What is the meaning of »modular«? Essentially, everything in the world consists of a com- bination of elements, thus, of modules. As the basic building block of the elements, an atom forms the smallest unit in a structure’s totality. It is part of a whole, serving as a model for decoding and making comprehensible complex systems. In many disciplines, for instance in music, the sequence of smallest common units derives from an ordering prin- ciple, a rhythmic spacing, and from an aesthetic whose modular structure has both regular and irregular proportions.
In architecture, the module and modular construction have been governing principles for thousands of years. Primates use twigs as construction components for their dwellings, si- milar to the more familiar birds’ nests. During the course of biological and cultural evolution, refined methods of connecting components have been developed. Increasingly sophisticated construction techniques have evolved parallel to the tools, construction equipment and weapons available, as well as to the construction materials and support systems that were chanced upon or invented.
Ever since the earliest settlements thousands of years ago, the module has defined construction. Its dimensions, production and assembly have developed from preindustrial craft techniques to the construction of buildings, arising with the invention of the steam engine and leading into the Industrial Era. The first computer in the 1930s marked another technological leap. So what possibilities does the computer offer today’s architects for de- sign and construction?
While industrial manufacturing methods still require a critical amount of similar elements for mass production, the use of computers increasingly facilitates construction based on customized production of short-run elements with individual formats and complex geome- tries. At least that’s the theory. Computer-controlled machines and robots cut and stack structural components according to drawings – i.e. data sets – developed by designers and producers. Thanks to these technologies, architecture in the digital age is experiencing an evolution in construction and modules. The pioneers in this area are the projects developed at academic parametric design research units.
This exhibition features various examples from the development of digital technologies, presented in their historical context and categorized according to material: wood, stone, concrete, metal and synthetics. The »Housing Modules« excursion presents a selection of special urban planning systems as a series of space modules.
The historical modules each represent a paradigm shift in the evolution of an individual material. Since modules offer a tremendous wealth of opportunity, this section does not attempt to deliver the full picture: rather it intends to serve as an inspiration for further exploration.
In keeping with the Architectural Particles theme, the exhibition’s architecture consists of a modular system of tetrahedrons and octahedrons. The resulting crystalline shapes high- light the connection to nature while recalling modular construction systems from various architectural eras.…

ices to regulate light and view while simultaneously producing both ornamental as well as material effects. The workshop will make extensive use of our Digital Fabrication equipment, coupled with Parametric Patterning techniques in Grasshopper for Rhinoceros. In a fast-paced and hands-on learning environment, participants will explore issues pertaining to the Coordination of Fabricated Parts through Unique Object Attributes, Baking Objects with User-Defined Attributes, Nesting Optimization with Rhinonest for Grasshopper, as well as the precise creation and manipulation of Computational Geometry through parametric modeling interfaces.
The workshop will begin with an examination of a set of Parametric Schemas as a means of identifying a suite of conceptual approaches to the regulation of light and view. Site-Specific Influencers such as Solar, Shading, Air Flow, and Viewing requirements will serve as Catalysts for the Parametric Articulation of a series of screening devices through shifting, perforating, and graduating Patterns. Emphasis will be placed on consistent organization of data through Lists and Data Trees and best practices for Professional Workflow Integration, File Modularity, and Data Visualization in Grasshopper.
SCREENING will focus on the Grasshopper, supplemented by the add-on Rhinonest as a means of fully integrating fabrication logics into Parametric workflows. The workshop is structured to allow each participant time to iteratively develop design prototypes, moving quickly from digital design environments to material artifacts and back again. As the next installment in the modeFab series, participants in this workshop will be introduced to and work directly with a large-format CNC Laser Cutter to develop scaled and 1:1 Component Assemblies. This workshop, particularly well suited for intermediate users, offers an in-depth and rigorous expansion on the topics of Algorithmic Design, Computational Geometry, and Parametric Modeling through the lens of Digital Fabrication and Prototyping with Grasshopper. As part of a larger online infrastructure, modeLab, this workshop provides participants with continued support and knowledge to draw upon for future learning.
Attendance will be limited to provide each participant maximum dedicated time with instructors.
Participants should be comfortable with the fundamental concepts of parametric design and general usage of Grasshopper.
Topics:- Parametric Design :: Fundamental Concepts and Essential Skills- Data Structures :: Working with Lists and Data Trees- Patterning Logics :: Shifting, Perforating, and Gradients- Pressures + Influencers :: Working with Attractors, Image Mapping, and Data Sampling Strategies- Material Strategies :: Folding, Lamming, and Lapping- Detailing :: Connection Logics and Tolerance- Coordination :: Logical Naming, Cut Order, and Sheet/Part Management- Fabrication Workflows :: Layouts and Nesting with Rhinonest…
ile but doesn't lock it, so when two people open the same file, whoever saves last, wins.- No. I think recording changes will be part of the same effort that will also involve storing the Undo data in the GH files. I designed the Undo/Redo system in such a way that it is (de)serializable, but it was never hooked up.- It would be fairly trivial to add an option for hiding all wires, long wires, wires connecting components that are not visible etc. However I think that the spaghetti effect is a result of a much deeper problem. I think we need to find ways to reduce the number of individual wires and make files more readable. Layers would be one way of solving it, but I can think of some other potentially interesting mechanisms.2) Readability- Groups are good. Panels with explanations or Scribbles can also help. Layers might be good for this as well. If people have specific ideas, I'd love to hear them.- The Remote Control Panel was dropped when I switched SDKs (from Rhino_DotNET to RhinoCommon). RhinoCommon back then didn't allow .NET plugins to create Rhino docking dialogs. By now Steve has added this functionality and the RCP is (along Cluster improvement) the #1 priority for Grasshopper 1.0. Unfortunately both are rather big projects so it's slow going.- Grasshopper2English sounds very ambitious. Especially when stuff starts to happen in parallel. What problem will such a feature solve?- In theory, yes. The GH file format is not defined, which is problematic. Each part of a GH file is read by whatever object is relevant, and each object can decide for itself how to write data to a GH file. This makes it difficult to read GH files without having access to those objects. It is however possible to do at least some partial exploration to try and extract names, nicknames, descriptions, positions and sources/recipients of objects in the file. Icons will not be possible.It sounds like a lot of this stuff would be excellent fodder for Grasshopper 2.0 Wip development, once Clusters are good enough and once the RCP is back in I'll start talking to Bob about what it means exactly to have a Grasshopper 1.0 out there and where to go next.Another big project which we've just started (i.e. hired someone for) is the writing of the Grasshopper help file(s). I'll do the coding required for the help file display/search etc. and Kaitlin will be in charge of actually writing topics and providing example files. This will certainly not be finished for GH 1.0, in fact it might not even make it into the public 1.0 releases. But Grasshopper is now a two-person project at least.…
have the latest GH 0.9.0006
2- Download and run the latest PanelingTools PT-GH installer for Rhino 5.0 (Windows 32 or 64).
Look forward to your feedback.
Enjoy!

New in this release:
-------------------
- PanelingTools rhi Installer now installs both PanelingTools plugin and PT-GH Add-On and save under (%appdata%\McNeel\Rhinoceros\5.0\Plug-ins\PanelingTools\...). Grasshopper 0.9 can now handle looking for ".gha" Add-On files in folders other than GH special components folder. You do not need to move files anywhere and it is strongly recommended to leave it where the installer puts them to handle future automatic updates and recovery.
- The release includes a major rewrite of all PT-GH components to handle multiple grid creation and paneling. Here is an example image of how it looks now with multiple grid input and paneling:

2012 Ultimate. I can open my component in Grasshopper, which has the null reference error 1. Solution exception:Object reference not set to an instance of an object,fine. Now I want to debug in Visual Studio, but my modules say no .pdb file only for any .gha,.dll's, and .rhp's found in C:\Users\Nathaniel\AppData\Roaming\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)\0.9.76.0\. The Debug only loads pdb. for symbols in servers and Grasshopper\Libraries, with one exception for Grasshopper.dll which is the only grasshopper component with a .pdb file in the \Mcneel\Rhinoceros...
Where are the .pdb files for all the other components Starling_0.2.gha, C_sawapan_media_x64.dll, Vector.gha, GH_IO.dll...? I'll run off the checklist of what I've tried:
GrasshopperDeveloperSettings turn off COF
made sure Debug Platform Target is 64, as well as Configuration Manager
add reference in Tools>Options>Symbols add reference (pdb.) to file for where the component files are found.
clicked on load symbols, but that doesn't help or save any .pdb's in my symbolcache.
added same location in ProjectProperies>ReferencePath
added same location in RhinoDeveloperSettings Add Folder
Do I not even need these symbols to debug? Is there a way to add .pdb's manually to my symbolcache? Why does my breakpoint say The debugger could not locate the source file 'C:\dev\grasshopper\1.0\root\src\GH_Component.vb'? I think I read that Grasshopper was written in .vb..Why does my callstack say Grasshopper.dll!Grasshopper.Kernel.GH_Component.New(String name, String nickname, String description, String category, String subCategory)? Why the ! after the .dll?
I am thankful for any input
