al structure that might resemble the shell structure of radiolaria - www.radiolaria.org - and then I want to manufacture it via 3D printing. Do you think mesh will be up to it?
Also, whether the mesh will work or not, could you please explain me the process on how you arrived to the mesh i.e. why you used all these components that you have used in your definition? As I do not want to directly copy and paste it, I want to understand on why you used all the other components to arrive to the resulting mesh. This will be a huge favour.
Knowing that the form that i have created is very important, do you think starting with the curves was the right thing or do you have any other way in mind to achieve this form with XYZ parameters?

rsuche deine Befehle später auf mein Modell anzuwenden.
Ja du hast Recht, ich sollte meine Fragen das nächste mal isoliert hochladen. Sorry für die "wirre" Datei.
Dennoch muss ich echt sagen, dass ich es mega schade finde, dass es einige in diesem Forum gibt die einen echt "runtermachen" indem sie ständig auf Fehler hinweisen und einen für komplett bescheuert halten. Es fällt eben nicht jedem leicht ein Programm ohne zusätzliche Hilfe sondern nur durch Ausprobieren zu erlernen. (Musste ich mal kurz loswerden!) Gut, dass es auch solche wie dich gibt, die einen Mut machen.
Gruß und nochmals Danke!…
p; 3D Urban ModelingOn the topography subject I get the next message: "One or more boundaries may be outside the bounds of the topo dataset" I'm not sure if it's the .IMG file I'm loading since I found so many IMG files nearing my polyline area (Miami Lat:26 Lon:-81 aprox.) or maybe my polygon doesn't match the topo area? I have no idea why it isn't working :(On the Shapefile subject, haven't been able to find a Building Height SHP File, so far have downloaded around 8 SHP files which only contain Polylines, my solution is to meanwhile randomize Z heights, but of course this data is not "technically" correct.P.S.: I've already tried all example links and also the ones posted by you and Benjamin in this video.Been strugling last few days, hope you can help me, thanks in advance!!…
button to generate such complicated and unruled geometry. Seriously, if you don't understand a geometry, how can you solve the structural needs and the bloody fabrication. Giant fast prototyping machines doesn't exist!
In a era where ressources and energy is getting scarce, I don't understand this trend of fancy no sence look like organic buildings. They just look organic in our human perception. Nature builds things with define physical and biochemicals rules, and this is why when they grow, they look like that. You should study Frei Otto publication from the 80's.. the IL publications. They were using physical models to generate physical structures that would be build in the physical world. Computers and softwares are dangerous as we distach from reality.
We put all this effort to generate these fancy forms, but no brain is put in structural optimization, energy efficiency (for instance in relation with the sun, or other natural elements)
IT technology goes faster than the time we have to reflect about it. (not talking about the technics).
As Frei Otto told me personally in our last discussion (talking about philosophy and architecture): " We have to define the OPEN QUESTIONS. Once these questions will be defined, you'll get answers".
I think we are getting to a question here: " How to use this technology to solve problems in Architecture?" Before that " What are the real problems in architecture?"
Maybe David should make a component for that? For instance, a button that could solve the loging and infrastructure problems for these millions of people living in the slums of Mumbai...
What about that Krish Raj?…

We design sail catamarans from 40' to 80' and occasionally some other stuff.
One may know it's a quite uncertain activity so I find myself tacking upwind on other seas from time to time, such as product design and jewelry. I also have side projects with mates regarding hi-fi or RC planes.
As for "static" architecture I had a couple experiences working on large "complex" buildings. Sadly French architects are not very familiar with BIM, parametric or even precise 3d modeling so I've been hired to introduce GH in the workflow.
I'm an un-authorized rhino trainer, sorry to say, but I just love teaching and meeting new faces, although I'm not as devoted as Danny ;)
I've been using GH both for modeling and analysis for about three years now and I'll daresay I became pretty good at it... I'm not a geek at all but it's just so useful, and it's really worth it sometimes €€€!…
ke 20 samples per day, 50 days out of the year for 1000 samples) from each panel and calculate the % of occlusion. Allow that % to be the % "open" of each panel. Design the opening in each panel to be something cool and proportional. Profit.
You could even break it down by a finite number of available panel types(say 0%, 20%, 40%, 60%, 80% open) and create an efficient production. All of these things can be paramterized to allow for more samples or more panel types as needed or based on your calculation limits.
The only exception would be proper environmental analysis, say, if you were trying to reduce solar gain in summer and allow for it in winter. You would want to split this calculation between when you need to be gaining heat and where you want to be shading. Then extrapolate the percentage between the two. You may even need a gradient of heat gain through fall/spring. The possibilities depend on how much you know about the mechanical requirements of the area/building.
That would be my approach. If I have more time tonight I will try and put something together on this as its been something I'd like to have in my back pocket....
Edit: You would also need to analyze the angle of incidence as it could have an effect on the amount of solar gain.....…
pproach of estimating wind loads using design codes such as ASCE7-05.
B) Hiring a wind expert to construct a physical model and and calculate wind pressures measured directly from a wind tunnel test.
A) will allow you to derive a site specific wind design pressure based on the height of the building, surface roughness, site location etc. Typically you then multiply this pressure by an appropriate co-efficent in the code for a given building shape.
The other atypical method it to use numerical approaches such as CFD. This approach is not yet accepted due to nuances such as of surface roughness.
Building deflection is again subjective. Doing a modal analysis and getting an idea of the frequency is better. You can increase the frequency by playing about with the building stiffness.
You need to modify the stiffness of the building to get the deflection down. i.e. play about with geometry, add extra members with stiffness, reduce weight, use material with higher elastic modulus etc
If you are getting a 7m deflection for a 400m building then I can right away that is way too soft. That is equivalent to 400m/7m or H/57. You want to be at least H/500 to H/1000 so aim for 80 to 40 mm.
Your wind load seems reasonable at 87 psf for that height of building

oks like all your GH components are disabled? I just tried baking the cone from my earlier code and using that but can't see anything at all.
OH! You had 'Display | Shaded Preview' disabled - why? Now I see that you have 80 X 55 'SFrames', which will be VERY SLOW. I never understood why you abandon 'PopGeo'? But that many points will be extremely slow either way. I won't wait that long.
You're making this way too hard for me, bobbi.
I said early on that it's best to work with a very low count until everything works properly. Solid unions are one of the ragged edges of Grasshopper; slow and prone to failure, depending on the complexity of the geometry (co-planar surfaces, etc.).
Good luck!
P.S. I can see two problems here:
Surface normal is in instead of out.
You didn't 'Cap Holes' on the lofted tubes so they aren't solid "Closed Breps".
I have no clue what you're doing. Do you? :)…
