Plug it² fornirà ai partecipanti un’effettiva padronanza delle più avanzate tecniche di modellazione digitale, approfondendo le metodologie della modellazione algoritmica e parametrica nel campo dell’architettura e del design del prodotto. Il corso è rivolto a studenti e professionisti dei settori della progettazione architettonica, design, moda e gioielleria, con esperienza minima nel disegno CAD bidimensionale (acquisita su qualsiasi piattaforma software) e si articolerà in lezioni teoriche frontali ed esercitazioni guidate.
INFO ED ISCRIZIONI

(Boundary Representation]. Thus a Brep is 2 things: the underlying "guide" surface and "regions" that do the massacre.
2. As delivered and if you chose the equivalent boolean some Delaunay faces are removed from the mesh IF their center (the projection in an automated made "min" plane) is contained (is inside) to a giiven hole. Now ... the anchors ARE not the white points ... they are their projections on the terrain (the red ones). Thus proper springs "pull" the white points towards the red ones.
3. Max span is a term used in that ugly part of life (the real-life) and indeed refers to some distance between mount points. For instance the Golden Gate has a max span of 1280 m. Span means money and big span ... er ... means lot's of money (even on trusses, considerably less so in tensile membranes).
5. Coding is like riding properly a proper Ducati (avoid the 999 at any cost): easy provided that you can ride it. Lethal in any other situation. But the good (or bad) news are that girls don't ride that type of bikes.
6. This makes me entirely off-topic > Oops > anything that I do/think points directly or indirectly (in most of the threads in this Forum) towards real-life AEC thingies. I never (ever) think within an Academic/Theoretical framework. BTW: Avoid social networks > or say hello to Skynet (or lobotomy).
7. You are very kind.…
to Daniel Pikers' Tutorial mesh relaxation tutorials we are already pretty far.
The Idea of our design is a hanging structure suspendend in a gap between buildings, where you can find places to rest, read or even to sleep. You can find privacy in the cocoons, that are connecting the planes with each other.
As structure we have a net in mind, that is tighter in the area of the cocoons and more transparent in the common areas, but we really don't know whats the right way to get to this point.
In the end of the project we need a printable geometry. We start our boxy design in Sketchup, and remesh it in Rhino. After that we feed it in our kangaroo definition.
1. A nurbs surface could give us more freedom (for postprocessing in tsplines) to form meshes with shorter and longer edges, representing our net. But I see now easy way to get a surface out of the relaxed kangaroo mesh.
2. Working with the kangaroo mesh could also work fine, if we'd find a way to control the edge length of the mesh (for example 20 cm in the common area and 5 in the privates) with an attractor point. Remeshing with Daniel's Plankton Plugin sadly doesn't work, I always get the "runaway faces circulator"-error.
3. It woud be great to convert the mesh to a hexagonal mesh, but I don't know any possibility to remesh an existing one...
You see, we're full of questions, but I really hope to get some help here :)

I have diagonals (bracings) which can buckle in these "non-regular" directions too, and they do. If I could add those values then in the Karamba model I could assign specific buckling scenarios..... I can see another challenge which will be at the ModifyElement component, I will not be able to choose these buckling lengths, in these directions.
Do you think this functionality can be added within short, or should I try to find another way to model these members?

I'm wondering how hard it would be to have an edit box which shows the
number the user could click inside of then type in a new number, then
hit enter. :)
2) How would I go about using one line from a table and assign each
field to a variable? Then, move a slider or something and use the values
from the next row?
background: I'm recreating elbows, Tees, and other fittings using
paramatric scripts, then baking and exporting them. Here's one source
table, http://www.wardfittings.com/Assets/PDFs/0902CatalogColorOld.pdf
page 5, the uniform elbows.
Current Setup: the attached ghx file. Create a point at 0,5,0 in a blank
document with units set to inches, then assign that point to the top
left 'Center Pnt' in the ghx file.
Current workflow:
a) Modify variables A, B, H, and Nominal Dia to match one line from the
table in the linked PDF file, page 5, table of regular elbows.
b) Select the 'Nodes' and 'Surfaces' with a drag box
c) Click 'Bake'
d) Switch to Rhino window, do the 'sellast' command.
e) Drag baked objects along Y axis so the center point is at 0,0,0
f) Run 'Join'
g) Run 'Cap'
h) set the 'node' points to a layer called 'nodes'
i) set the surface to a layer called 'fit-3d'.
j) select the surfaces and nodes
k) export selected
This elbow that I'm doing only has 12 rows, so doing it the above method
doesn't take THAT long. I'm also going to be doing a couple with larger
tables like the Tee on page 8, and in other spec files. As you can
imagine, entering in EACH value into a slider is a bit tedious.
I'd love to take the pdf table, run it through an OCR program to convert
to excel, modify the headers so the ghx script knows what they are, then
paste it into grasshopper, or save it and have grasshopper read it, and
I be able to move a slider or something to to select one line at a time.
Has anyone done something similar? ie: assigned one row in a table to a
predefined set of variables, each variable coming from one field in the row?
Thanks for taking the time to read this message. :)
I'm making a rhino script to do steps d-k, so that part will be much faster.

the other pluggins again, I doubt that problems arise and if I already have them Which are due to the autodesk pluggins that I can install on another computer or mount a virtual machine, but I doubt it, I simply had to install Grasshopper first and then the rest.)
Problem:
Good day, afternoon or night, please help I can not install the Grasshopper plugin 0.9.76.0 in Rhinoceros 5SR13, I do not know if it is because I uninstalled the version of 32 Bit of Rhinoceros and I only have installed the 64 Bit version, I have installed on Rhinoceros 64 Bit:
Autodesk Realtime Renderer 2014 x64 Autodesk Shape Modeling 2014 x64 Autodesk T-Splines 2015 x64 V-Ray 2.00.23938 for Rhinoceros 5 x64 V-Ray Express 2 for Rhinoceros 5
I would infinitely appreciate the resolution to this problem, for the moment I can not think of anything other than to uninstall everything and leave only installed the program Rhinoceros 5SR13 with Grasshopper 0.9.76.0 and nothing more.
I already tried to download another new file from Grasshopper 0.9.76.0, which ruled out that this installer is wrong, what I could do is look for another version of Rhinoceros but I have the newest one or one of the newest versions: Rhino_5.13.60913.21340_x86_x64_Multi. Exe
I understand that the Grasshoper installer is showing me a message where it says there is a Win32 exception where the system can not find the source file, what I do not know is if this exception has to do with the Windows C /: Folder: Windows, subfolder: System32 or I do not know if it refers to that as I do not have the 32 bit version of Rhinoceros maybe the installer gets confused and generates the installation error exception.
Another thing to which the exception is associated is the start process file: Start.nfo or start information.
There is also a programming argument for file upload errors of boolean operations (geometry operators) associated with the platform operating system, a process called child process.
Also appears another note that says the installed package of a plugin called inspector and I do not know what else I can not explain.
I do not know what to do, I just happen to uninstall and install everything and I do not think the Rhinoceros installer has any errors, I have Windows 10 edition of Red Stone 1 of 64 Bit.
Thanks and if anyone had this problem and solved it please tell me how to fix it or if someone knows about programming you can tell me why all those errors or exceptions are.
Greetings, have a nice day, afternoon or night wherever you step or stand or wherever you are sitting or lying down.…
tal fabrication tools. DLAB will investigate natural growth processes in relation to innovative concepts of architectural tectonics and fabrication. We will carefully interweave these concepts with interaction and participatory design to create full-scale working prototypes. The programme will be formulated as a two-phase process. During the initial phase participants will benefit from the unique atmosphere and facilities of AA’s London home. The second phase will shift to AA Hooke Park campus and revolve around the fabrication and assembly of a full-scale architectural intervention.
Some of the most prominent features which the participants will be exposed to during DLAB include:
Teaching team: Participants engage in an active learning environment where the large tutor to student ratio (5:1) allows for personalized tutorials and debates.
Facilities: The Digital Prototyping Lab (DPL) in AA London houses cutting-edge facilities for the fabrication of physical outputs through digital fabrication techniques. The facilities at AA Hooke Park allow for the fabrication of one-to-one scale prototypes with a 3-axis CNC router.
Computational skills: The toolset of DLAB includes but is not limited to Rhinoceros, Processing, Arduino, and Grasshopper.
Theoretical understanding: The dissemination of fundamental design techniques and relevant critical thinking methodologies to the participants through theoretical sessions and seminars forms one of the major goals of DLAB.
Professional awareness: Participants ranging from 2nd year students to PhD candidates and full-time professionals experience a highly-focused collaborative educational model which promotes research-based design and making.
Fabrication: According to the specific agenda of each year, a one-to-one scale prototype is fabricated and assembled by design teams.
Lecture series: Taking advantage of its unique location, London, DLAB creates a vibrant atmosphere with its intense lecture programme conveying the diverse expertise of professionals in the areas of digital design and fabrication techniques.

this occasion, but it could be converted for DT in no time). Requires some minutes more as regards ... some things, but the usual update is due to some days.
Bad news: it's C#
Good news: User's Manual :
1. That thing (the C#, not me) after sorting (in a "sequential way", so tho speak) the panels (their order was chaotic) allows you to start the massacre by locating a focus of interest (and the user controllable +/- Range derived from it).2. The Range is variable (obviously) and takes care not to exceed the indices of the panel list (OK, that's elementary).
3. If you click the right button (Sadistic Q: where is it? he he) things are deleted and a new constantly self-updating list is your new List. Thus the massacre of panels is totally controllable. An autoZoom thing is also included (free of charge, but it's a bit nerve braking). Zoom factor is variable as well.
4. Then you move over (via the index slider) and start the massacre again. Notice the change of Range.
5. If you turn begin to false (initialization) and then begin to true > start all over again.
6. The other C# thing allows you to increment the index slider in a rather more convenient way. It's a bit weird: it uses delegates (A delegate is an object that knows how to call a method) and events (An event is a construct that exposes just the subset of delegate features required for the broadcaster/subscriber model - but don't ask what this means, he he) in order to talk with your slider (with a defined NickName) and perform the required value control.
NOTE: without realizing it you've just (indirectly) asked one of the most important questions even exposed in this Noble Forum. I hear you : what question? Well ... wait some days for the mother of all threads: "Total control in collections on a per Item basis"
may the Force (the dark option) be with you (and me)
best, Peter…
Rubicon (ii.e. some programming language [I would strongly recommend C#] > the Dark Side > years of pain + tears > hell or heaven?).
Back to that pile or worms of yours (I hate "simple" cases, he he).
0. if you want rounded lips ... Styrofoam is the only solution (+ sanding [buy a mask and some decent cigars ... path is long and hilly]). if not > goto 5/6.
1. by what means you think that you can shape Styrofoam? Do you have access to some CNC foam cutter? Or the only tools that you have are ... 2 hands and a knife? (or a thermal cutter). Accuracy is a BIG issue here: chances are that panels won't "fit". Solution is available in the forthcoming V3.
2. male "protrusions" on Styrofoam is kinda 3rd marriage > AVOID at any cost > this would end up in tears.
3. female ones are safe ... thus we need a proper "insert stripe" that must be compatible with the Styrofoam adhesive and strong enough to hold the pieces until the glue cures (it takes time, there's no instant Styrofoam adhesives around). Maybe aluminum (hard to cut by hand) or balsa (very expensive) or plywood (best option).
4. Some CNC foam cutters they can't shape the female "crevices" > be prepared (a thermal tool may(?) cut the mustard).
Note: panels made with Styrofoam look miserable because reality and theory differ. They also look miserable as well (and kitsch and miserable).
5. making the panels with (marine) plywood ... well this yields far superior accuracy and therefor aesthetics but (a) yields max panel thickness constrains, (b) introduces max panel dimensions constrains (c) yields packing issues [waste material] and (d) requires a totally different "connection" approach: it doesn't make sense to do some female crevice ... unless the plywood is very thick (expensive + heavy).
Note: Designing (pro option) self supporting "rib" reinforced sandwich composite panels ... well this is a bit far and away from what you can handle at present time.
So ... I've suspended the male/female thingy until you decide the final policy: it's the material/detailing that should dictate the method(s) AND the whole design and not the other way.
This is what we call bottom-top design approach (dinosaur Architects follow the top-bottom: disastrous + naive + naive + naive + avoid).
6. Plan ZZTop: make a stand alone autonomous perimeter frame per panel (marine plywood: imagine "thickening" these abstract beams shown inwards per panel) then join these frames by means of bolts (easy) and fill the "gaps" with Styrofoam (hmm). Note: you can reinforce the frames by a variety of means (say: a secondary "beam" sub-structure) achieving a rather elegant all overall solution.
This is the best solution by roughly 666 miles.
