was not all there myself. Overall the night wasn't that productive so I wanted to apologize, I will do a better job in the future.
Attached to this message is the Assignment sheet for the upcoming week. Please post the picture of the models before 7:00 PM Monday 2/16.
Here is a link to the completed script from last night, as well as the Rhino file and presentation pdf.

A few notes:
- I added two separate tags to the end of the script. One set is for the 3D model of your form, locating where the pieces originally come from. The second set is for the flattened out sections, which can be etched on your pieces to actually locate them when they are physically created. Play around a bit in the script and try to understand what is going on between the different parts.
-Baking: We went over baking in last weeks class. You right click on the component you want in the physical realm and select bake. Rhino will then ask you to select a layer to place the items on. I would suggest having two layers, one will be for cutting and one will be for etching (when you bake the tags(optional)). Once the pieces are in Rhino, you can use the Make2d command and export to AutoCad where you can laser cut (if you are unsure about this process, Google it as there are numerous tutorials).
-I would recommend using chipboard as it is the cheapest and most readily available, but don't let me chain your creativity if you come up with another material.
I look forward to seeing your guys models. See you Monday!

pavilion) and from that i want to fabricate it using some paper or card bored .
for modeling the pavilion i used a simple kangaroo based algorithm to generate the desired form using mesh 3d plane faces . there was no problem with this part and i was able to get the mesh from geometry out put . then i wanted to use that output mesh to panelize it and then adding tabs and the nesting and cutting to get the parts. but the problem was every tutorial i looked up were using surfaces to panelize and nest so this was the first problem to convert the mesh into a surface and then panelazing and nesting . i tried using the mesh2nurbs but it didn't work out for me . (because i needed a single surface not some poly surfaces) . (attachment | input mesh )
so i started from the beginning and tried using a surface as an input for kangaroo and thus getting a surface as an output so i did that and tried to create a surface by the Surface from points component . and the result was not good the surface was kinda messed up and the the reason was the points were not ordered well i guess . so this was another problem for me . (attachment | input surface)(picture below)
so basically i have a few main questions :
1. is there a tutorial or any topic or book or somthing that explains from 0 to 100 from design to fabrication (as an example a pavilion) ?
2. can i use the mesh to panelize and nest and then fabricate ? and are there any tips or tricks to it ?
3. is the starting from surface for me a good idea or not ?
i am extremely sorry for talking this much and i'm grateful for the time you spent on reading this .
best wishes ; Babak.

The output of Modal Analysis (at a given frequency) is a list of point (x,y,z), each of them has the three coordinates and the maximum displacement in the direction normal to the surface (that's not flat)
Point number x y zmax1 24,007565 337,876028 -0,6545572 -28,0404705 337,947773 0,7760153 57,141457 316,757768 -0,8413914 18,667466 314,814543 -0,235288
My idea is:
-import stl surfaces of the object (violin)
-import Modal Analysis data
-deform stl (or Nurbs) surfaces using something like a customized CageEdit
-animate this deformation from zero to maximum displacement
-give a color to deformation (or first-second derivative of the interpoled deformation curves)
My wish is to have closed surfaces at any steps, and to create "natural" deformation shapes.
I just tried to import MA data. I was trying to create an array of circles with given x,y,z and radius, I could not figure how to separate information of position and radius when importing the file:
file content:
0,1,0; 5;2,1,3; 2;5,2,6; 4;
thanks for yout attention.
Looking forward to hear you soon!

hat aren’t completely there. BIM will have to continue to evolve some more if their supporters want to get to realize the promise that still is. I can’t say much about PLM, but I would say that both BIM and PLM should be considered in future developments of GH and Rhino. David has said several times that some GH limitations regarding geometry and data structures (central to interoperability) are actually Rhino limitations. So, I wouldn’t put so much pressure on David for this, or at least I would distribute the pressure also on the core Rhino development team.
Talking about Rhino vs. GH geometry, there is one (1) wish I have: support for extrusion geometry. GH already inputs extrusion elements from Rhino, but they are converted to breps. Is not a bad thing per se. The problem is when you need to bake several breps that make the Rhino file to weight several hundred MB. When these breps are actually prismatic, extrusion-like solids, is a shame that they aren’t stored as Rhino V5’s extrusion geometry in a file of just a couple of MB (I overcame this once with an inelegant RhinoScript that wasn’t good for other people). This was one of RhinoBIM’s main arguments. We can develop a structural model made of I-beams in GH using the Extrude components. We should be able to bake them as extrusions. That would also work for urban models with thousands of prismatic massing buildings (e.g. extruded footprints). Even GH’s boxes are baked as breps! Baking boxes as extrusions could be practical for voxelated or Minecraft-like models.
(2) Collaborative network support. Maybe with worksession handling, or something that aloud project team members to work on a single definition or in external references or something alike. I know there is another Rhino limitation on this, but maybe clusters are already going in that direction?
And maybe on the plug-ins domain:
(3) Remote control panel that could be really “remote”, like from other computer or device. There is an old Android App for that, but is not only a matter of updating. I mean, it would be great to control a slider with the accelerometer of an Android phone, but to have that on an iPhone will require another development team. If GH could support networks, a remote counterpart of a RCP plug-in could be developed as a cross-platform web app. I don’t know if you can access accelerometer functionality through HTML5 already, but for now, asking a client (or an spectator or any stakeholder for that matter) to control your sliders from gestures of his/her own phone would be awesome (maybe Firefly will fill that hole?).
(4) GIS support. GH already imports .shp files. Meerkat can even access the database, but what about writing to shapefiles or generating our own with databases processed/generated in GH?
(5) SketchUp support. Not only starchitects and corporations are using GH in the AEC. There are a lot of small firms, freelancers and students interested. Most of them use SketchUp for 3D modeling (not CATIA, neither Revit). Yes, you can import/export .skp from Rhino, but if GH could support nested block at bake time (also mentioned by others), it could write .skp files with complex relations of blocks (that are called components in SketchUp) and nested groups, going beyond what Rhino can export.
(6) Read/Write other formats. There are some challenges with proprietary formats that are not completely supported by Rhino, but they’re still a lot of open formats that are relevant to the fields of GH users, like stl and ply for 3D-printing. It could be nice to write mesh colors to a ply for 3D-printing a colored prototype based on GH colors. There are others, like IGES, STEP, COLLADA, etc. and 2D, like svg, odg and pdf. Some of them could offer special formatting options like custom data that the format supports but nobody uses just because is impractical to access this from direct modeling environments (but not from visual programming).

ngoing Co-de-iT research called “inFORMed matter“.
The “inFORMed matter” research project focuses on the exploration of additive fabrication processes, aiming to inform as in to produce form through the morphogenetic properties and capacities of matter by embedding further information structures during the fabrication process itself.
The goal is to go beyond the current state of prototyping, according to which the physical prototype should be as close as possible a clone of its digital counterpart, thus making fabrication a purely replicational phase. Instead, by coding and embedding additional levels of information aimed at mapping and defining material features and behaviors as well as different deployment patterns from which physical and aesthetic properties arise, the production and digital fabrication phase becomes an integral part of the design process.
The workshop it’s focused about the exploration and development of the whole process of design and digital manufacturing through additive processes of ceramic mixture materials.
[.] Workshop topics:
- Anticipate material behavior through digital simulation: test and apply different tool-based conditions and parameters (extrusion direction angle, speed of extrusion, variable layer thickness, etc … ) and evaluate the consequent material behavior in order to get useful feedback for the next iteration of the digital model. The aim is to understand how to embed material properties as code/information during the digital design phase, fine tuning it towards the desired effect-outcome. - Seamless design-to-machine pipeline: shorten the information pipeline from the design process to the constructor machine. This is achieved by acting on both factors: informing directly the machines by generating the necessary code in the design tool and build the design process around the capacities of the machines involved. - Embed morphogenetic material properties as design factors: understand and manage such properties, behaviors and their potential morphological outcomes for different materials, from clay to biologic matter, in order to map and use them as an atlas of expressive possibilities and performances of the material. - Understand constraints and opportunities determined by the chosen constructor agent/machine: learn to use and manage different machines to handle the extrusion tool for additive processes and learn to evaluate and exploit the influence, constraints and given opportunities provided by different machines and movement technologies.
During the workshop will be used as tools for handling the special ceramic extruder, a customized 3D printer, type delta, and a 6-axis Comau Robot NJ 60.
The final output will be then the result of influence, cooperation and conflict of these aspects upon, with and onto one another. Only successfully combining computational simulation, material properties and capacities and machine constraints and opportunities we can effectively evaluate and push further the design process potential and foster design and fabrication skills and sensibilities that will form the basis of a more comprehensive awareness in regard to the relations between computation and material aspects.

nteraction in the design of an enclosed volume.
Revolutions have occurred through architectural history and vary widely in terms of design methods and fabrication techniques. Focusing on inspiring natural form‐finding techniques, AA Athens VS works towards producing a large‐scale interactive prototype that alters in real‐time the perception of interior space.
Technology and architecture are coupled for the third year in Athens with a novel agenda of transforming an enclosed area and creating internal contrasting city‐life characteristics that transcend the local conditions. In collaboration with the National Technical University of Athens, Cipher City: Revolutions explores participatory design and active engagement modeling and continues building novel prototypes upon horizontal planes.
The toolset includes mainly ‐among others‐ Rhino Grasshopper, Processing and Arduino platforms. With the completion of the Programme participants receive the AA Visiting School Certificate. In 2013, the design agenda of AA Athens will connect with the agenda of AA Greece VS in the city of Patras. Participation in both Programmes will allow for a more extensive learning experience through additional tools like Autodesk Maya, Autodesk 3D Studio Max and more.
Discounts
The AA offers several discount options for participants wishing to apply as a group or participants wishing to apply for both AA Athens and AA Greece Visiting Schools:
1. Standard application
The AA Visiting School requires a fee of £600 per participant, which includes a £60 Visiting Membership. If you are already a member, the total fee will be reduced automatically by £60 by the online payment system. Fees are non-refundable.
2. Group registration
For group applications, there will be a range of discounts depending on the number of people in the group. The discounted fee will be applied to each individual in the group.
1. 3-6 people group: £60 (AA Membership fee) + 540*0.75 = £465 (25 %)
2. 6-15 people group: £60 + 540*0.70 = £438 (30%)
3. more than 15 people group: £60 + 540*0.65 = £411 (35%)
3. Participants attending AA Greece VS and AA Athens VS | 40% discount
For people wishing to attend both AA Greece VS and AA Athens VS, a discount of 40% will be made for each participant. (The participant will pay the £60 membership fee only once.)
£60 (AA Membership fee) + (540*0.60)*2 = £708
Eligibility The workshop is open to architecture and design students and professionals worldwide.

ut it locking up again.
I'm told we have to wait for Grasshopper 2 wed to Rhino 6, in months or years from now since Grasshopper isn't multithreaded. It does look for the escape key but not reliably at all.
Here is a response from the developer to my same sort of question:
http://www.grasshopper3d.com/forum/topics/emergency-top-for-solutio...
David Rutten: "if it was doable, I'd do it, but Grasshopper runs on the main UI thread which means that no key presses come through until the process is done. Right now I check for escape key state (circumventing the key-press events) at certain points during the solution, but the more I check the more I slow down the solution, and there are large areas where I can't check because it's not my code that is taking up all the processor power in the UI thread."
I solved my own problem in that case by leaving the solver disabled in the menu and then invoking it manually as a recompute menu command that works once anyway. That won't help you with a rogue script though, but will let you set things up without Grasshopper recalculating each change.
With the solver disabled, when you have to manually invoke a recompute, that necessary action can help remind you to save first.
I tried assigning the Rhino command GrasshopperUnloadPlugin to F4 in Rhino settings but in the test case of populating a box with 1000000 random points (Vector > Populate 3D), the freeze up cannot be ignored as you access Rhino, which remains grayed out as a program even when you highlight its window, and nor can you get any Grasshopper command-S in while its running forever. That's only the equivalent of 100X100X100 points yet it still locks up Rhino so long. Thinking in this very simple case clarifies things, since it it won't let go then complex scripts may have some better chance but really the problem is in the system itself.
At least the Rhino close box works, so you don't need the Windows Task Manager :-).
There are also autosave options in Grasshopper preferences that creates an autorecovery file for the next time you open the same document.…
learn, or as an alternative to your morning coffee + cross-word puzzle.
Rules:
Contributions can be posted by anyone. Either selected from a previously posted problem from the general discussion (please acknowledge original poster), a selection from one of the many grasshopper+ primers (please include credits) something you think is fun, curious about, or even something you want to learn.
We should keep the entries dated so we can track them. One new problem per day (so if you see one posted for today- there is always tomorrow).
User(you) adds post titled: date-name of problem.
Solutions will be posted with breakdowns, either in logic procedure, etc. And in the spirit of the NY Times, an explained solution will be posted as well within the following days.
Remember there are multiple ways to solve a problem- however the “official” post should include a “clean and elegant” (or simplest) solution. So that all learning can develop better scripting habits.
Rules: an explanation.
1- Submission categories are as follows:
Native
Plug In
Scripted
Each category should have a difficulty rating - 1 to 5 perhaps.
They should be included in title for clarity-
Date_NameOfProblem_Native Plugin or Script_Difficulty
2. Since we are an international community, and this is an open group- a C+G day starts at the time of 10 am local poster’s time.
3.Anyone can set the next question. However the same person cannot set two days in a row. If a question is up- then next person needs to wait until the following day to post. You can PM Danny Boyes or Myself (Monique) if you are having posting issues- (i.e.: how to post, or have been trying to post, but keep missing the opportunity)
4. Answers are presented in the typical grasshopper community response way: in the form of examples, and/or screen shots. For screen shots: make sure the nodes are legible, if you do a function inside a node make sure we can see what you did. Verbal explanation. Maybe picture of result.
The difference between this group and the general discussion is that the poster should know how to solve the problem, be able to post a solution up themselves.
5. The poster judges the answer. They should offer a sample solution as well when they declare the winner.
However overall quality control may be checked by moderators of the group.
6. Still thinking about this one. …
