as the design table? I think this could be 'drawn' and constrained in Inventor in a lot less time. I know the GH model would have a lot of flexibility, but in this case, what can you do with it that wasn't provided by an Inventor model?
Only the 27 lines mentioned were modeled in Rhino, the rest is modeled with GH.
The 5 hrs involved thinking about the approach, defining vertical lines, tilts, elevations, pitch of the roof, intersections.
Once I had decided what my approach would be, and tested the logic with those first lines, points and data path arrangements, it only took one more hour to get to this:
Which is actually quite fast, compared to MCAD workflows.
If you already have components (columns, beams, etc.) modeled and ready to drop into a project, of course it is lightning fast to model simple projects like this example.
I am not as much interested in those situations, because improving efficiency is straightforward and obvious.
I'm more interested in situations where there are no pre-defined families of objects, in which case you need to start from scratch.
The GH model I'm showing is modeled from scratch, except for the 27 lines in Rhino.
Here's one obvious advantage to modeling with GH, once the definition is set-up, it's virtually effortless to change inputs and alter the overall design. Here's an example, lets say we wanted to extend the roof 3 more units, curling away from the original direction.
Plan view before:
And after:
An MCAD app will also allow you to do this, as long as the location of additional elements follows the existing geometric method of definition. What happens if you want completely change the way you locate columns, roof slope, intersection points?
In MCAD, you'll need to re-model the underlying geometry, which will take the same effort as the first round. In GH, this process is not only much faster, it's open to algorithmic approaches, galapagos, etc. and it just takes some simple re-wiring to have all down-stream elements associate themselves to this new geoemtric definition.
For instance, here's the same definition applied to two curves, which are divided in GH, the resulting points are used as a starting point for lines directed at normal from curves.
This is not so easy to do in MCAD.…

schi (Authorized Rhino Trainer) tutor: Maurizio Arturo Degni
La simulazione fisica interattiva, integrata nell’ambito della modellazione parametrica consente di indagare nuove soluzioni formali ottimizzate per l'architettura ed il design. Il workshop approfondirà le strategie e le principali tecniche di FORM FINDING utilizzando il motore fisico KANGAROO integrato a plugin di analisi strutturale (MILLIPEDE). 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 tridimensionale. Sarà rilasciato un attestato di partecipazione firmato da Arturo Tedeschi in qualità di Authorized Rhino Trainer.

s for input and the result will be always in SI! There is an internal conversion from Model Units to Meters. [Warning: I developed and tested the 'bug only in meters and I haven't tested it [intensively] for other units. I recommend you to use meters for now.]
2. Correct! If you input a mesh the component will use the initial mesh as the test grid else it will be meshed based on the gridSize which you won't have full control...
3. Correct! That's how you can minimize the time of the study to zero not calculating what you don't need to know! :)
4. Correct! [and that's why the direction of the normal of the surfaces does matter. It should face outward.]
5. You can do that but then the accuracy of the result could be questionable in some cases. As djordje said center points are the test points and probably you don't want all the glazing to be evaluated based on one single point in case the glass is partially shaded. I understand why are you doing that though and I will add the option to average the result for each test surface similar to what I show in this video 22:27 (http://www.youtube.com/watch?v=aoMy4O3vN6g), so you can subdivide the test surface and then get the average results for the surface.
Best,

HiIf you are encountering a problem with rhino 6 versions don't worryFollow these steps.1. Download SYNTACTIC from https://sites.google.com/site/pirouznourian/syntactic-design2. Install it and go to the installation folder, Drag & drop SYNTACTIC(green one) over your grasshopper canvas.3. Close your rhino and reopen it. 4. Type GrasshopperDeveloperSettings5. Tick the Memory load *.GHA assemblies using COFF byte arrays option6. Run grasshopper and enjoy plugin
I hope this helps,
Best regards,
Pirouz

re and more integrating our work into architecture. Since I am doing all this for the company I work for, its all a bit secret until ready to be shown unfortunately.
There was a version where its running on 2 computers - 1 does all the rendering and 1 is just to control it using a 27" touchscreen.
Then there was also a way you could export the animation you are creating as a Maya file for rendering, which was fun. I actually had to reverse engineer a maya animation file, but it is in plain text so it was just a bit tedious, but it worked and you could then render it properly in the incredible Octane Render Engine (http://www.seltzdesign.com/blog/octane-render-lives-again). Time constraints were a factor, so there is a lot of work that lies dormant right now, but hopefully gets resurrected at some point.
I am not so active in the vvvv forum any more, because I'm not using it so much any more, but if you are stuck or need some pointers you can always send me a message here.…

Becouse
i can't use the partition tool since for diffrent days there are
diffrent amounts of hours of sun. eg 1 januari from 8:00 to 16:00
and 1 februari from 8:00 to 18:00. Wich is making the information
in the list very hard to handle.So can anyone help me find the average yearly sunvector for every hour
for each month
for example
avg sunvector for the whole of januari1:00, avg sunvector (the avareages of all sunvectors at 1:00 in januari)2:00 , avg sunvector3:00 , avg sunvectoruntill24:00, sunvector tempavg for the whole of februari1:00, avg sunvector2:00 , avg sunvector (the avareages of all sunvectors at 2:00 in februari)3:00 , avg sunvectoruntill24:00, avg sunvectorand this for every month of the year.
I want to be able to optimize a surface wich is divided into multiple meshes (so for each part of the surface i want to relate it's normal to the vector of the sun). I'm not so much interested in the visualisations. I hope this is atleast abit understandable.ps: this question is atleast abit simular to my previous question on wich i got some really good help, wich i'm very gratefull for.
Thanks in advance!Included: gh file + the epw file i'm using…
ariations, but each seems to lack the sophistication to generate a ‘zip’ that retains its general shape over the whole curve.
Basically I’m trying to understand the process behind this: http://www.schindlersalmeron.com/index.php?option=com_content&task=view&id=27&Itemid=29
Here is an image of the latest definition.
1. I draw a curve in Rhino, and then define it in grasshopper. I also define the point as the beginning of the curve.
2. I offset the curve to a specified depth, based on structural member
3. I generate a line from the point at a tangent to the curve, then rotate it a
defined angle.
4. I find the intersection between the rotated line and the offset curve. Then generate a tangential line from this new point
5. Line is rotated at the same angle as before.
6. Process repeated.
The idea is to then generate a circle of defined diameter at each of the intersection points, then find the intersection of the circles with the curves, which are then joined up with straight lines to create the ‘zip’. This would mean a lot of copy-pasting and list management that I’m not really capable of with my limited grasshopper experience.
I had tried generating points at intervals along the curve and then eventually generating lines from one line to another with a shifted listed to form the tooth angle, but it wouldn’t retain its shape over the entirety of the curve.
Does anyone have any advice for how to tighten up this definition? I imagine that I will need to delve into vb.net scripting to address the recursive nature of the process.
I fear that I’m going about this in entirely the wrong way...
Of course the next step is to flatten out the curve for CNC manufacture.
Any help would be greatly appreciated! The potential for using grasshopper in design is amazing, and I would love to gain a deeper understanding of it!…
