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,

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.

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)

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.

r "virtual partitions" as follows:
What I mean "air walls" here, is derived from the description of the E+ documentation with the header of "Air wall, Open air connection between zones". (Page 17, http://apps1.eere.energy.gov/buildings/energyplus/pdfs/tips_and_tricks_using_energyplus.pdf)
As I understand, the term "air wall" used in E+ here refers to a description of something like "boundary condition" between adjacent interzone heat transfer surfaces, but not a kind of "construction or material" (like air space resistance or air gaps within a wall/double glazing window).
The main purpose of introducing the "air wall", is to simulate or approximate the airflow/convection/natural ventilation effect between multiple thermal zones which are connected by a large opening.
In my previous tests, using HBzones and GB, I managed to create the gbXML file which can be successfully imported to DB (without assigning any constructions within HB). And the adjacency condition can be recognized automatically by DB, even when I did not use the "Solve adjacencies" component in HB - shared surfaces between multiple thermal zones are recognized automatically by BD as "internal - partition"(which are standard partitions, but not virtual partitions).
In order to create/approximate "virtual partition", I need to manually draw a "hole" in the standard partition surface (fig.1&2). Again, the reason why we want to use "virtual partitions"(or "air wall") is that it allows airflow between multiple thermal zones which are connected by large openings and we could get different temperature of the each subdivided thermal zone which compose a large thermal zone.
My question is, if there is a possible way to simulate/approximate this kind of "virtual partitions"(or "air wall") in HBzones or in GB? If so, I would like to test if DB recognizes it or not. Actually, we expect that there is no need to involve any manual operations (like drawing a "hole" in the standard partition surface) in DB, due to an automatic optimization loop.
Thank you!
Best,

50 and reduced the 'cell size' slider to 0.5. When the 'Azimuth' angle is changed to 180 +- 90 (dawn or dusk), the points are widely dispersed, reducing the density and increasing the number of cells in the "sparse grid". Under these conditions, the number of cells was ~2000 and the Profiler time for 'Boundary' went up to a full minute or more each time 'Altitude' or 'Azimuth' was changed.
So I created this code to benchmark some alternatives and found two interesting things:
'Boundary' surface performance (v.1) is not linear. As the number of surfaces goes from 1000 to 2000, the time per surface goes up dramatically.
I tried three alternatives for creating a rectangular surface at a given point that are all substantially faster: v.2, v.3 and v.4. For 2000 points, v.4 is 150 times faster than v.1 !!!
Performance of v.2, v.3 and v.4 are similar and all scale up very well. To benchmark beyond 2000 points, I recommend disabling the VERY SLOW v.1. At 5000 points the 'Pop2D' component takes ~11.3 seconds but v.3 and v.4 take less than one second to generate 5000 surfaces!
See boundary_2015Nov19a.gh attached.
So I replaced the 'Rectangle' and 'Boundary' components in my sun reflection model with v.4 in focus_2015Nov19b.gh (also attached) and the performance is amazing.
I'm sure someone has mentioned this performance issue with 'Boundary' on the forum before but as with many things, I didn't realize what a major obstacle it can be until I discovered this for myself.…

grout lines, a tile surface and tile perimeter poly line). I then use that as a Mesh (from Rhino) in the second definition.
2. I can tile out the mesh surface and rotate all the tiles in 90 deg. increments.
To get what I wanted. I took the Mesh and have copied it in series to make a grid. I can then control the dimensions of the grid. X and Y extents. I can also rotate the tiles around their centers.
The spacing of the grid is set from an edge curve of the tile (or mesh). This sets the size of the squares in the grid themselves.
See definition, images and Rhino 4 File, to give the definitions a shot. I have labeled how to use them.
My question -- how can I randomly rotate squares in my grid? I would like the deg of rotation to be random and also which tiles they are.
Also how might I rotate (every other tile) for example? So that I can control the pattern more?
Thoughts?
Thanks!
