azione parametrica e generativa attraverso Grasshopper, plug-in di programmazione visuale per Rhinoceros 3D (uno dei più diffusi modellatori NURBS per l‘architettura e il design). Il workshop mira a gestire e sviluppare il rapporto tra informazione e geometria lavorando sui sistemi ad involucro in condizioni specifiche.La discretizzazione di superfici (pannellizazione Nurbs o Mesh), la modellazione delle geometrie attraverso informazioni (siano esse provenienti da analisi ambientali, mappe o database) e l’estrazione e la gestione di queste informazioni, richiede la comprensione di strutture di dati al fine di gestire completamente processo che va dalla progettazione alla costruzione.I partecipanti impareranno come costruire e sviluppare strutture di dati parametrici per informare geometrie ‘data-driven’ e come estrarre le informazioni rilevanti da tali modelli per il processo di costruzione.
Modulo 2 – Il workshop, volto a promuovere le nuove tecnologie digitali di supporto alla progettazione e alla fabbricazione, esplorerà l’integrazione tra design e prototipazione tramite processi di stampa 3d di materiale ceramico al fine di comprenderne allo stesso tempo sia il comportamento del materiale che i vincoli e le opportunità offerte dall’utilizzo di tali tecnologie.Infatti utilizzando grasshopper ed una macchina a controllo numerico i partecipanti apprenderanno le modalità per la generazione parametrica dei modelli e la creazione del codice per la loro prototipazione (Gcode creato direttamente in Grasshopper). Il workshop darà quindi ai partecipanti la possibilità di testare direttamente i loro elaborati digitali stampandoli in modo da comprendere come le informazioni articolate tramite tali strumenti di design producano specifici effetti sia morfologici che estetici.…

Le tecniche saranno applicate a diversa scala: dall’architettura (modellazione di superfici e coperture a semplice compressione) al design del prodotto, dove la simulazione digitale sarà integrata a tecniche di refinement (WEAVERBIRD). Il workshop e rivolto a studenti e professionisti con conoscenze base di modellazione algoritmica con Grasshopper. Maggiori Info……

2- Yes I'm considering the first eigenfrequency and deflections.
Best,
Aryan…
So here are my questions:
I read Tips for designing Statically Feasible Structures in Section A.3 and find some importart things regarding my purpose of using Karamba. First deflections are small as compared to the size of the structure. How can i assume that the deflections are small or not?
Is it the rule of thumb of Delta<L/300 which is explained later in the section?
If so, how can i know how much are the deflections happen on beams and columns in the model?
Is it the maximum displacement (output of Analyze)?
If it is, why the maximum displacement output in my formula only produce 1 result (0.552711) although my model is table-like structure? Whether i saw in the manual (section 5.6.1, picture of simply supported beams), the maximum displacement output produce 3 results.
Last, how can i assess the results (which is the delta/deflections, which is the L, can i know the delta/maximum deflections on each beam)?
Thank you
Best regards,
William S.

you post a screenshot of what the message coming from its readMe! output looks like?2) Close your Grasshopper and Rhino.3) Download "Revo Uninstaller Pro" from here. It is free for first 30 days, which is what we need.4) Right click on the RevoUninProSetup.exe and check if the file is blocked. If it is, unblock it.5) Run the RevoUninProSetup.exe file and install "Revo Uninstaller Pro".6) Uninstall "MapWinGIS" with "Revo Uninstaller Pro". It is important that "Revo Uninstaller Pro" deletes not only files from MapWinGIS installation folder, but also all other leftovers (as registry inputs). Here is a small tutorial on how to do that. Watch it from 6:10 till the end.7) Restart your PC8) When your Windows boots up, make sure that you are logged in as Administrator!9) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".10) Turn off your Windows Firewall.11) Then turn off your custom Firewall (in case you have another one, besides standard Windows Firewall).12) Completely turn off your Antivirus.13) Download again the MapWinGIS-only-v4.9.4.2-x64.exe.exe file from here.14) Right click on the MapWinGIS-only-v4.9.4.2-x64.exe file and see if it is blocked. If it is, unblock it.15) Right click on MapWinGIS-only-v4.9.4.2-x64.exe file and choose: "Run as"... Administrator.16) One the installation preparation steps start, choose "Full installation". Wait for the MapWinGIS installation to finish.17) Right-click on "Rhino 5" icon and then choose: "Run as administrator".18) Open the the ironpython_admin.gh file again, and again post a screenshot of the message coming from its readMe! output.19) Drop the "Gismo Gismo" component to Grasshopper canvas. Post a screenshot of the message coming out from its readMe! output.
So we will need in total three screenshots of the readMe! output messages.
Thank you once again for being patient, and sorry for the large number of steps.…

on the division points (see rhino screenshot below, left side is what I'm describing. there is also a note in the screenshot of the GH file)
Unfortunately it doesn't work for multiple cell inputs.
I've also tried flattening the points into one big list and re-creating the polylines with sublists but with no luck. The points are not ordered the way it would need to be to use sublists from domains created by 2 series of numbers. So this is problematic becuase each cell has a different number of vertices. That method would work if I can create unevenly spaced intervals that match the number of vertices on a given input, but I'm not sure how to do that.
Like would it be possible to create a series of numbers whos step size varies with each step? e.g. series that starts at 0, steps up in size 5, then 7, then 11, etc. ant there are x amount of values in the series?
Any ideas how to get this working? Either with this definition or a different method?
Thanks,
Brian…

N, O}. In this case it's very obvious what needs to happen. You want to create lines combining the following points {AK, BL, CM, DN, EO}.
If the second set however only contains 3 points {K, L, M}, it is no longer obvious. The default behaviour for Components is to keep on matching points until both sets are depleted. This is called Longest List Matching. It will give you 5 lines, that connect the following points: {AK, BL, CM, DM, EM}. As you can see, the last point in the second list (M) has been 'recycled' three times.
You can also change the default data matching behaviour. For example if you change it to Shortest List, then the component will stop working as soon as the smallest set is depleted: {AK, BL, CM}. In this case the points D and E are completely ignored because no 'sibling' could be found for them in the second set.
A third option is Cross Reference matching, which will create all possible combinations: {AK, AL, AM, BK, BL, BM, CK, CL, CM, DK, DL, DM, EK, EL, EM}.
However the best solution in this particular case is not to muck about with the data matching, but instead Graft your data. Grafting means that all the items in a set are moved into their own little set. Thus, if you graft {A, B, C, D, E}, you actually end up with 5 sets, each containing a single item {A}, {B}, {C}, {D} & {E}. When you combine this new data layout with your second set {K, L, M}, each grafted item will be matched with all the items in the second set, this is after all how Longest List works. So you end up with a data layout that looks like this: {AK, AL, AM}, {BK, BL, BM}, {CK, CL, CM}, {DK, DL, DM} & {EK, EL, EM}, which is very similar to the Cross Reference matching, but retains more of the original layout. I.e., it's not just a huge list of all the lines, they are still five groups of three items each, which is a far more informative layout than Cross Reference would generate.
I'm afraid at this time of night this is the best I can explain it.
