ll geometry.
The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process.
In this little model, the starting point actually is a bit obvious, the foundation.
The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters.
Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor.
You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH.
Anyways, here's a screen capture of the foundational lines:
In the first group of components, the centerlines of the rear columns are modeled:
And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly.
The same was done for the rear columns:
The above, believe it or not, took me the first 5 hours to get.
Here's a screen capture of what the model and definition looked like after 4 hours, not much:
If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really.
I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…

Il comfort visivo e la gestione dell’illuminazione naturale in relazione al risparmio energetico diventano sempre più rilevanti per una progettazione innovativa degli edifici. Ad esempio, il nuovo protocollo LEED 4 riconosce crediti per le simulazioni di daylighting e conferma l’importanza degli aspetti progettuali per “collegare gli occupanti con lo spazio esterno, rinforzare i ritmi circadiani, ridurre i consumi di energia elettrica per l’illuminazione artificiale con l’introduzione della luce naturale negli spazi”. Senza strumenti software per la simulazione della luce non è possibile ottenere risultati di qualità. Radiance è un software validato, utilizzato sia a livello di ricerca che dai progettisti ed è tra i più accurati per la simulazione professionale della luce naturale e artificiale. Non ha limiti di complessità geometrica ed è adatto a essere integrato in altri software di calcolo e interfacce grafiche. Queste ultime facilitano le procedure di programmazione. Le principali e più versatili saranno oggetto del corso (DIVA4Rhino e Ladybug+ Honeybee, plug-in per Grasshopper e Rhinoceros 3D).
Il corso è rivolto a progettisti e ricercatori che vogliano acquisire strumenti pratici per la simulazione con Radiance al fine di mettere a punto e verificare le soluzioni più adatte alle proprie esigenze. Sono previste lezioni di teoria e pratica con esempi ed esercitazioni volte a coprire in modo dimostrativo ed interattivo i concetti trattati.
Le domande di iscrizione devono essere presentate entro il 16 novembre 2016.

Meeting Agenda:
1) Discuss what the group would like to learn this term through our regular scheduled meetings. Topics include the priority and sequence of Grasshopper exercises we would like to explore during the winter term from http://www.digitaltoolbox.info/grasshopper_basic.html and Processing tutorials from the Processing Handbook I received from MIT.
2) Watch the Matt Storus Church Machine video and have a discussion about parametric and generative tools in design.
If you have a chance, please read the following article by Tim Love called Between Mission Statement and Parametric Model at:
http://places.designobserver.com/entry.html?entry=10757
3) Discuss a possible design build project over the following winter and spring terms using the skill set this group is developing. Conversation led by Chris Nielson (please see comments below for a brief backstory)
4) Discuss possible applied research and design work for the National Conference on the Beginning Design Student paper, Machine Craft and the Contemporary Designer: exploring parameters and variables through making physical artifacts. I wrote the attached abstract and submitted it for the conference the past fall and it was accepted. To continue with the research I need to assemble a team of students that will help explore the principles I set forth by making physical objects with the cnc router. In exchange for helping with the research I will show participants how to use the cnc router, how to author machine code and provide you with the cnc controller interface software necessary to simulate machine movements. Not to mention, your work will be sited in the research paper I present at the conference at UNC Charlotte in March. More tomorrow night, of course.
Thank you for your interest and I hope to see you there.
Sincerely,
Erik Hegre

All,
In response to Erik, who requested that I describe my intentions in a design-build project and to the article posted (definitely required reading for this group) I propose that we begin development of a project that spans the realm of "sustainable social" architecture and parametric design. The particulars of such a design do need to be made concrete, and it will be important to define the goals of such a project.
Therefore, I would suggest that this serve as a forum for the next few weeks for those interested in producing a built project. I agree with Nico that it may not be feasible to create the built piece, whatever it may be, this term; however we should have the groundwork and a plan in place by the end of the next 10 weeks.
Either way, I would ask that everyone who is interested to please provide as many concepts to this forum to begin a discussion. If you are indeed interested, please submit goals that this project could achieve (energy, socially, aesthetically, economically, related) and perhaps what you envision the project to physically be (shading device, public bench, water catchment, interactive thermal contraption, etc . . . )
I look forward to hearing your thoughts!
Cheers,
Christopher…

ears many bridges had been constructed and even more has collapsed or has been destroyed. Today Warsaw is connected by eight road bridges and two rail bridges, only few of them have a bike lanes. Modern cities are going through rapid changes. Hamburg has announced that in less than 20 years they are closing the center for cars, Copenhagen notes major incrementation in bike use, city bike system has been successfully introduced to many Polish cities. Warsaw bicycle net path is still very weak and probably the most urgent issue is to build a new bridge overpassing the Vistula River. This year Warsaw City Council decided to run an architectural competition for a new bridge. Architecture for Society of Knowledge and Architektura Informacyjna, Master's Programs of Architecture Faculty of Warsaw University of Technology, and Architektura Parametryczna, a digital design educational platform, invite for workshop: Outcome: The primary goal of workshops is to find the most optimal position for new bicycle bridge (or bridges) in Warsaw to enhance the global accessibility and Walkscore. During the workshop the participants will develop an interactive tool that will help to understand the accessibility changes by connecting Vistula shores with bicycle bridges. Program: Four days event will include coding part and learning how to apply digital tools into urban scale problems along with lectures of invited guests. This workshop is planned for intermediate user that understand and use Grasshopper. The workshop will be conducted in English.

sshopper for the developable surface problem. Thanks for connecting me to those discussions on it. Those images are fantastic!Andrew, I took inspiration from your approach and my ran with it! This works for my curve set: Here's what's going on. We can see the curve C as a graph above some plane P, and we'd like to find the local maxima, ie, it's critical points. We segment C into smooth, convex segments and use the Extremes component to locate the global maxima of each segment. This can include the endpoints of segments as artifacts, which we filter out. Now we have only genuine critical points of C with respect to P. We also check the endpoints that we filtered out earlier. If a tangent at one these points is perpendicular to P's normal vector, the point is in fact critical, and is included in the final point stream.
The pro of this is that it uses Extremes as the 'workhorse', and this component is likely to use an efficient and numerically robust zero/maxima finding algorithm, such as bisection, or Brent's method.The con is that it requires curves to be segmented at their inflection points, and for each segment to turn less than one full rotation around any line whatsoever that is parallel to P. Note that segmenting curves in these ways are interesting and useful problems in their own rights. Without this kind of segmentation, my approach will in general fail to extract some critical points on splines with inflection points, and on curves such as helixes or spirals. However, arc-segmented polylines naturally have these properties, and these are enough for my purposes for now.
In a different direction, I think I will try the method of bisection to extend your curve subdividision / dot product graphing approach. Essentially we'd sample the curve, use your dot product graph construction to find regions that we know will contain a zero crossing, subsample on those regions, and repeat the process until we've hit floating point precision for the result. This probably takes around 20 to 50 iterations. But it would give the highest quality results possible, and likely be far more stable than any dubious, inflection-point-splitting, wild-turn-avoiding, subtle-bug-inducing approach that I'll come up with otherwise, hah.Andrew, thanks for the code and inspiration!…
d of interpenetrating surfaces somewhere:
Now all links (except a possible single ball on the very end of odd numbered ball series) are four balls long, including the jostled ones. Without that step, those items simply don't appear in the output, leaving way too big of gaps to ignore, eventually leaving huge gaps at later stages of segment doubling:
So if I turn the jostling multiplication factor way down it should work imperceptibly:
Ta-dah! The jostling strategy WORKS! Granted, only in this special case where I know I'm dealing with adjacent pairs of worms along a curve, not generic objects arranged in space by some artist.
Now I just need to wrap the multiple Python script components I'm stringing together into one script.
How long does the full 2400 balls take, finally? It took 12 Python scripts that merge pairs, to achieve this breakdown: 2400 -> 1200 -> 600 -> 300 -> 150 -> 75 -> 38 -> 19 -> 9 -> 5 -> 3 -> 2 -> 1. Time was 2 minutes 50 seconds, so there is some extra struggle for 2X as many balls as 1200 that took 1 minute 20 seconds, but only ten more seconds.
