e to constrains, I HAVE to do it like this (I can't 3D print everything or opposite).
First
I have no idea how to make the panels, without so many duplicate Edges, Faces etc.
Second
I can't figure out how to align the triangle panels to fit in the construction, so it can be assembled ideally without glue. This problem is both conceptual (I can't figure out how to do it fiscally) and grasshoper-wise - I don't know how to organize data list and produce a global movement, so that the triangle parts do not intersect with each other, BUT intersect the 3d printed construction part (where they fit fix in or just fit and can be glued).
Triangles will be milled out from 3mm Plexiglas, BUT I will not have an option to mill at an angle, so only 90° edges.
3D printed parts will be executed by a high level production powder printer, so it should hold good.
Any ideas?
best,
cuki

File) 2. I have designed a curved Trichordal-Truss from one curve in Rhino.
The Truss is lying in the XY direction and the footer is placed on the zero point.
3. And now my problem:
I want to put the Truss-object on the feet, move 90°
(from the XY axis to Z axis, see sketch 1).
4. Then copy / move the truss to all 36-points of ellipse (see sketch 1).
5. Align the 36 trusses with the center of the triangle .
pointing at the center of the ellipse (see sketch 2).
6. Using a slider to change the position of the 36-Trusses at der ellipse.
Variable distance between Truss and ellipse (see sketch 3).
Thanks for you Answer.
Best regards

multiply of variants from Galapagos, to have a chance for better analysis and comparability after. I also would like to use more then one solution in my design after.
In old topics i found kind of 3 solutions.
1.Change Galapagos to octopus ( what don t really want to do, i am kind of happy with Galapagos)
2. Use Slingshot! and MySQL Database ( it s look a little bit too complicated from the first view)
3. Use Colibri and Design Explorer Platform (looks kind of pretty way to solve my problem)
So i tried to add Colibri components to my definition , but have some mistake in the Colibri Aggregator after adding the Genome "An item with the same key already been added". I think it comes because for some steps i am using the "Gen Pool" and not a normal slider. Is it a way to connect Gen Pool and Colibri (i really prefer to have it, then a lot of sliders in some cases)?
And the second question (if i will get it solved with gen pool), could i somehow controll the recording process? For example i would likte to record only variants wit fitness over 90% or start recording just after 20. generation and record till the end?
I also opend for all other possibilities to reach the same goal (record/save/bake multiply variants from galapagos)

The measure Entropy is newer. I hereby explain it (from my PhD dissertation):
Entropy values, as described in (Hillier & Hanson, The Social Logic of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

is useful to replace values (even if I cannot replace the same value for example "fraction radiant" in two different internal gains), but not to add new stuff, as in our case.
As you may recall, we were able to add our internal gains through the additional strings, but we have the problem of the default ones that we can not change or remove.
We've noticed that People, Lights and ElectricEquipment Internal gains are located inside the "runEnergySimulation" honeybee command inside the Python script.
We were thinking of two possible quick alternatives while waiting to be able to fully customize the internal gains with honeybee.
For the first one, if it is possible, you could make a "modified" "runEnergySimulation" command for us in which you cut off the Internal Gain parts, so that we can add them as text in the additional strings part. Alternatively you could show us where to add the additional strings we need inside the runEnergySimulation command so that we can add the values we need to run the simulation.
For clarity, these are the internal gains in idf file we need (that are inside de gh file in the panel just below the additional strings command)

thought that architect's love for drawing comes from the necessity of translate abstract ideas into built 3D reality, and the technology behind that 2D representation has not evolve so much until some decades ago. Our teachers come from that times: times when computers try to find their place in the reality representation world. If you try to imagine that people that have always drawn with pencils adapting to this new tools...some become fan of new methods, other just keep the old fashion workflow (like Andrew said in the article, Schumacher VS Graves)
We've bear (at least Andrew and me :P) in 80's with first video games, computers (I still remember my old x286 with 1Mb RAM and 20Mb of HD and that MS-DOS interface)...New technology was natural for us...But there is a big difference between traditional drawing and new computer aided tools: the learning curve. To draw you only need to take a pen and put over a paper (that interface is understood by children easily) , but traditional computational tools (new touch interfaces are out of this group) are based in a complex logic and environment that is not easy to understand for some people.
In the workshops I'm teaching in, I try to put all that tools (new and old one) in my students hands and motivate them to mix and use them together (Andrew knows a little bit about that :P). Why not to make a lines sketch with GH and then print it and render with some markers?; the last step could be scan the result and enhance it in Photoshop adding textures, vegetation, some background...There are no rules, only a bunch of tools to explore and use to develop your ideas, evolve and finally represent them.
I bet to the touch interfaces (with some augmented reality sauce) like that one that will be able to blend both worlds, analog and digital, offering that fluidity and natural interaction that Grave miss in digital tools. And our generation attached to this "not natural" interfaces will need to change its mind and adapt to that new and amazing interface that our children will love.

e volume. The yellow line above.
This volume, green on the above image
So with this there was an intersection with the Brep volume of the chair and the lattice.
After that I used cocoon. Here the parameters I used for the Brep and curve. So The Brep was offsetted.
The model is 80 unit height and cell size is 0.2 so roughly there are 400 divisions in Z. If cubic it will give 6.4 millions of cells. To my point of view it is important to choose well the cell size in order to have not hundred of million of cells. Here 6 millions was usable. The general thing with Cocoon is alwas to test it on small objects first.
A close view of mesh. Edge length is 0.1 unit. There are 6 millions of triangles.

not seem to manage to download the data... (see picture attached).Djordje, do you have any idea about what I can I do or check to fix this?
I just tried to run the component for a couple of locations and it successfully downloaded the data from opentopography.org:
When did you try to run the component? An hour ago?Can you try again?
Other question, just to be sure, regarding the "origin_", is it the central point that you to get out of the output mesh/surface? And does it need to be the point at the actual point elevation or does it need to be the point projected on the ground floor (as I do in my definition)?
Yes, you are correct about both things: it's the central point and it will lie on the actual terrain (it will be projected to the terrain).The latitude and longitude information from the _location input will be taken to find the origin_ point. Elevation will always be ignored, as elevation is calculated from the elevation of the point laying on the terrain at those particular latitude-longitude coordinates.Please let me know if I did not precisely gave the answer to your questions. Or if I misunderstood your question.We are here to help with any issue.…
