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.
https://www.dropbox.com/sh/3g6fnue93dk8iub/AAB88CNVCtC64cmz_ENLlojQa?dl=0
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!

e chosen to dive into Grasshopper. I’m about 6 months in. If some of my comments are completely off, please take that to mean that a feature is too inaccessible to a newish user rather that it’s just missing, as I may have stated.
One of my primary pain points is this. Things that can be done in other programs are invariably easier in other programs. This is a big enough issue that I doubt there’s an easy solution that an armchair qb like myself can offer up.
The interface:
I’ve used a lot of 3D programs. I’ve never encountered one as difficult as grasshopper. What in other programs is a dialog box, is 8 or 10 components strung together in grasshopper. The wisdom for this I often hear among the grasshopper community is that this allows for parametric design. Yet PTC (Parametric Technology Corp.) has been doing parametric design software since 1985 and has a far cleaner and more intuitive interface. So does SolidWorks, Inventor, CATIA, NX, and a bunch of others.
In the early 2000's, when parametric design software was all the rage, McNeel stated quite strongly the Rhino would remain a direct modeler and would not become a parametric modeler. Trends come. Trends go. And the industry has been swinging back to direct modeling. So McNeel’s decision was probably ok. But I have to wonder if part of McNeel’s reluctance to incorporate some of the tried and proven ideas of other parametric packages doesn't have roots in their earlier declaration to not incorporate parametrics.
A Visual Programming Language:
I read a lot about the awesomeness and flexibility of Grasshopper being a visual programming language. Let’s be clear, this is DOS era speak. I believe GH should continue to have the ability to be extended and massaged with code, as most design programs do. But as long as this is front and center, GH will remain out of reach to the average designer.
Context sensitivity:
There is no reason a program in 2014 should allow me to make decisions that will not work. For example, if a component input is in all cases incompatible with another component's output, I shouldn't be able to connect them.
Sliders:
I hate sliders. I understand them, but I hate ‘em. I think they should be optional. Ya, I know I can r-click on the N of a component and set the integer. It’s a pain, and it gives no feedback. The “N” should turn into the number if set. AAAnd, sliders should be context sensitive. I like that the name of a slider changes when I plug it into something. But if I plug it into something that'll only accept a 1, a 2, or a 3, that slider should self set accordingly. I shouldn't be able to plug in a “50” and have everything after turn red.
Components:
Give components a little “+” or a drawer on the bottom or something that by clicking, opens the component into something akin to a dialog box. This should give access to all of the variables in the component. I shouldn't have to r-click on each thing on a component to do all of the settings.
And this item I’m guessing on. I’m not yet good enough at GH to know if this may have adverse effects. Reverse, Flatten, Graft, etc.; could these be context sensitive? Could some of these items disappear if they are contextually inappropriate or gray out if they're unlikely?
Tighter integration with Rhino:
I'm not entirely certain what this would look like. Currently my work flow entails baking, making a few Rhino edits, and reinserting into GH. I question the whole baking thing, btw. Why isn't it just live geometry? That’s how other parametric apps work. Maybe add more Rhino functionality to GH. GH has no 3D offset. I have to bake, offsetserf, and reinsert the geometry. I’m currently looking at the “Geometry Cache” and “Geometry Pipeline” components to see if they help. But I haven't been able to figure it out. Which leads me to:
Update all of the documentation:
I'm guessing this is an in process thing and you're working toward rolling GH from 0.9.00075 to 1.0. GH was being updated nearly weekly earlier this year. Then it suddenly stopped. If we're talking weeks before a full release, so be it. But if we're looking at something longer, a documentation update would help a lot. Geometry Cache and Geometry Pipeline’s help still read “This is the autogenerated help topic for this object. Developers: override the HtmlHelp_Source() function in the base class to provide custom help.” This does not help. And the Grasshopper Primer 2nd Ed. was written for GH 0.60007.
Grasshopper is fundamentally a 2D program:
I know you'll disagree completely, but I'm sticking to this. How else could an omission like offsetsurf happen? Pretty much every 3D program in existence has this. I’m sure I can probably figure out how to deconstruct the breps, join the curves, loft, trim, and so forth. But does writing an algorithm to do what all other 3D programs do with a dialog box seem reasonable? I'm sure if you go command by command you'll find a ton on such things.
If you look at the vast majority of things done in GH, you'll note that they're mostly either flat or a fundamentally 2D pattern on a warped surface.
I've been working on a part that is a 3D voronoi trimmed to a 3D model. I've been trying to turn the trimmed voronoi into legitimate geometry for over a month without success.
http://www.grasshopper3d.com/profiles/blogs/question-voronoi-3d-continued
I’ve researched it enough to have found many others have had the exact same problem and have not solved it. It’s really not that conceptually difficult. But GH lacks the tools.
Make screen organization easier:
I have a touch of OCD, and I like my GH layout to flow neatly. Allow input/output nodes to be re-ordered. This will allow a reduction in crossed wires. Make the wire positions a bit more editable. I sometimes use a geometry component as a wire anchor to clean things up. Being able to grab a wire and pull it out of the way would be kinda nice.
I think GH has some awesome abilities. I also think accessing those abilities could be significantly easier.

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.

, Engineer and Researcher from France with broad programming experience. He is the author of the City in 3D Rhinoceros plugin for creation of buildings according to geojson file and with real elevation. Guillaume already created a new component: "Address to Location". It enables getting latitude and longitude values for the given address:
2) Support of Bathymetry data: automatic creation of underwater (sea/river/lake floor) terrain. This feature is now available through new source_ input of the "Terrain generator" component. Here is an example of terrain of the Loihi underwater volcano, of the coast of Hawaii:
3) A new terrain source has been added: ALOS World 3D 30m. ALOS is a Japanese global terrain data. Gismo "Terrain Generator" component has been using SRTM 30m terrain data, which hasn't been global and was limited to -56 to +60 latitude range. With this addition, it is possible to switch between SRTM and ALOS World 3D 30m models with the use of source_ input.
4) 9 new components have been added:
"Address To Location" - finds latitude and longitude coordinates for the given address.
"XY To Location" - finds latitude and longitude coordinates for the given Rhino XY coordinates. "Location To XY" - vice versa from the previous component: finds Rhino XY coordinates for the given latitude longitude coordinates. "Z To Elevation" - finds elevation for particular Rhino point. "Rhino text to number" - convert numeric text from Rhino to grasshopper number. "Rhino unit to meters" - convert Rhino units to meters. "Deconstruct location" - deconstructs .epw location. "New Component Example" - this component explains how to make a new Gismo component, in case you are interested to make one. We welcome new developers, even if you contribute a single component to Gismo! "Support Gismo" - gives some suggestions on how to make Gismo better, how to improve it and support it.
5) Ladybug "Terrain Generator" component now supports all units, not only Meters. So any Gismo example file which uses this component, can now use Rhino units other than Meters as well. Thank you Antonello Di Nunzio for making this happen!!
Basically just forget about this yellow panel:
This panel is not valid anymore, so just use any unit you want.
6) A number of bugs have been fixed, reported in topics for the last couple of weeks. We would like to thank members in the community who invested their time in testing, finding these bugs and reporting them: Rafat Ahmed, Peter Zatko, Mathieu Venot, Abraham Yezioro, Rafael Alonso. Thank you guys!!! Apologies if we forgot to mention someone.
