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.…

and export the geometry out to VVVV to render it LIVE! RawRRRR. In this case, a digital audio workstation Ableton Live, a leading industrial standard in contemporary music production.
the good news is that VVVV and ableton live lite is both free.
https://www.ableton.com/en/products/live-lite/
i am not trying to use ipad as a controller for grasshoppper. I wanted to work with a timeline (similar to MAYA or Ableton or any other DAW(digital audio workstation)) inside grasshopper in an intuitive way. Currently there is no way of SEQUENCING your definition the way you want to see that i know of.
no more combersome export import workflows... i dont need hyperrealistic renderings most of the time. so much time invested in googling the right way to import, export ... mesh settings...this workflow works for some, for some not ...that workflow works if ... and still you cannot render it live nor change sequence of instruction WHILE THE VIDEO is played. and I think no one wants to present rhinoceros viewport. BUT vvvv veiwport is different. it is used for VJing and many custom audio visual installation for events, done professionally. you can see an example of how sound and visuals come together from this post, using only VVVV and ableton. http://vvvv.org/documentation/meso-amstel-pulse
I propose a NEW method. make a definition, wire it to ableton, draw in some midi notes, and see it thru VVVV LIVE while you sequence the animation the WAY YOU WANT TO BE SEEN DURING YOUR PRESENTATION FROM THE BEGINNING, make a whole set of sequences in ableton, go back change some notes in ableton and the whole sequence will change RIGHT INFRONT of you. yes, you can just add some sound anywhere in the process. or take the sound waves (sqaure, saw, whateve) or take the audio and influence geometric parameters using custom patches via vvvv. I cannot even begin to tell you how sophisticated digital audio sound design technology got last ten year.. this is just one example which isn't even that advanced in todays standard in sound design ( and the famous producers would say its not about the tools at all.) http://www.youtube.com/watch?v=Iwz32bEgV8o
I just want to point out that grasshopper shares the same interface with VVVV (1998) and maxforlive, a plug in inside ableton. audio mulch is yet another one that shares this interface of plugging components to each other and allows users to create their own sound instruments. vvvv is built based on vb, i believe.
so current wish list is ...
1) grasshopper recieves a sequence of commands from ableton DONE
thanks to sebastian's OSCglue vvvv patch and this one http://vvvv.org/contribution/vvvv-and-grasshopper-demo-with-ghowl-udp
after this is done, its a matter of trimming and splitting the incoming string.
2) translate numeric oscillation from ableton to change GH values
video below shows what the controll interface of both values (numbers) and the midi notes look like.
https://vimeo.com/19743303
3) midi note in = toggle GH component (this one could be tricky)
for this... i am thinking it would be great if ...it is possible to make "midi learn" function in grasshopper where one can DROP IN A COMPONENT LIKE GALAPAGOS OR TIMER and assign the component to a signal in, in this case a midi note. there are total 128 midi notes (http://www.midimountain.com/midi/midi_note_numbers.html) and this is only for one channel. there are infinite channels in ableton. I usually use 16.
I have already figured out a way to send string into grasshopper from ableton live. but problem is, how for grasshopper to listen, not just take it in, and interpret midi and cc value changes ( usually runs from 0 to 128) and perform certain actions.
Basically what I am trying to achieve is this : some time passes then a parameter is set to change from value 0 to 50, for example. then some time passes again, then another parameter becomes "previewed", then baked. I have seen some examples of hoopsnake but I couldn't tell that you can really control the values in a clear x and y graph where x is time and y is the value. but this woud be considered a basic feature of modulation and automation in music production. NVM, its been DONE by Mr Heumann. https://vimeo.com/39730831
4) send points, lines, surfaces and meshes back out to VVVV
5) render it using VVVV and play with enormous collection of components in VVVV..its been around since 1998 for the sake of awesomeness.
this kind of a digital operation-hardware connection is usually whats done in digital music production solutions. I did look into midi controller - grasshopper work, and I know its been done, but that has obvious limitations of not being precise. and it only takes 0 o 128. I am thinking that midi can be useful for this because then I can program very precise and complex sequence with ease from music production software like ableton live.
This is an ongoing design research for a performative exhibition due in Bochum, Germany, this January. I will post definition if I get somewhere. A good place to start for me is the nesting sliders by Monique . http://www.grasshopper3d.com/forum/topics/nesting-sliders

k ecotect; and 'export mesh to ecotect' usually auto link, but my computer won't link. Please help out.
please post such request in our group so we get an request email, thx.
For your problem you have to use the newest geco v1.033 and grasshopper v09.0012 or higher.
This will solve your problem.
If you use grasshopper for rhino 5 we will release a updated version which also works for this.
currently you have to copy the files manually to the components folder
thx....
After installed the new version of grasshopper geco, here is error again
Error: solution exception: Could not load file or assembly 'Geolink, Version=2.1.563.0, Culture= neutral, Public KeyToken=bull' or one of its dependencies. The system cannot find the file specified.
Here is the error on ' Link Ecotect (EcoLink) ' in grasshopper geco.
Urgent!!! Please help!
PLEASE IDENTIFY which files copy manually from where to components folder?
thanks…
ok at the various available ways to reference geometry and data in ghPython:
ghdoc is the standard document for rhinoscriptsyntax. We can use it all the time and it is meant to be as quick as possible, in order to slow down rhinosciptsyntax in Grasshopper as little as possible.
It is also possible to just reference or create geometry in memory using RhinoCommon methods.
The third and last document is the usual Rhino document, which is also accessible in ghPython: Rhino.RhinoDoc.ActiveDoc.
All these three styles are valid and useful for certain purposes and code writing styles.
Specifically, you are asking to take data from ghdoc, obtain the geometry, and finally add it to the Rhino document. This is essentially baking in ghPython, right?
I am attaching an example.
When you have a document available and a Guid, you can use rhinoscriptsyntax.coerceXXX(guid) in order to obtain geometry, or specific types of geometry.
Similarly, scriptcontext.doc.Objects.AddXXX() allows to add geometry to the document. There are lots of variants for this. You can refer to the RhinoCommon documentation for all methods in the ObjectTable class, or all methods in the ghPython one are on GitHub.
Please let me know if you need more information. I hope this is helpful,

s lectured at my university; one of his projects is a free-form shell pavilion, based off of the finger-locking joinery of sand dollars. He has a great time-lapse video of the form finding process on his website, which is worth a watch if you haven't seen it already. It appears as if he uses Galapagos or some other evolutionary approach for his solution. When I saw that Daniel Piker replicated this using only Kangaroo, I was thrilled.
I believe that in order to get smoother, less clumsy results from the PlanarHex, it is almost necessary to ensure that your setup is conducive for the definition to work. I think this includes beginning the definition with the hexagons having the ability to be EITHER concave or convex (Lunchbox). In Daniel's script, I think he set the default value at .5, which was in the middle of the two options and resembled a square. I think also that the number of hexagon cells in the U and V direction should be setup in a way that they can lend themselves to a proportion that is used later in the definition.
Here is a quote from Piker that better explains the importance of the proportions and edge lengths in the setup:
The ratio of U/V divisions need to be chosen so that the initial edge lengths are close to equal.
When planarizing, particularly with hexagons, we need to ensure that the polygons do not become self intersecting. Here this is achieved by constraining the maximum and minimum edge lengths to some ratio of the overall average edge length. For this to work though, it helps if the initial state has them within or close to this range. [...]
Judging from the photo you provided of your results from the PlanarHex, I think some of the issues may be a result of you having a mixture of trapeziums and hexagons. This could potentially be causing the mangled appearance of the resultant shell.
Again, I do not know if this will be too much help for you as I am somewhat of a beginner with Kangaroo. But if nothing else, I hope that this can serve as a catalyst for what could be an interesting discussion about free-form vaults and shell structures... Also, check out the work of Philippe Block if you haven't. Here's a picture of a hexagonal vault model that he designed that is quite lovely.

component that let you modify an existent .EPW file as you want, also just few hours or days or months of it.
This is a preview of it.
This new potential component creates a copy of Epw file automatically starting from an existing EPW file. In this case I modified dry bulb temperature from June to September, I added 5 °C to the original values.
or you can create your own values, for example here I plugged random values.
Or you can copy and paste your values from .xls column of a weather data into a panel component.
All your modified files are stored into a folder that you want.
I think should be useful a component like this. Anyway, I'll try to finish it as soon as possible.
Best
