hen 6 triangles meet at a vertex. You can create double curvature by having a valence 5 (positive curvature, like a sphere), or 7 (negative curvature "saddle shape").
Such meshes were studied by Alain Lobel in the 1980's (maybe even before that). There is a paper mentioning them in the proceedings of AAG2014. Repetition of panels is also studied here, with the use of clustering, which can be very efficient.
You can look at the SMART Clustering plug-in developped by Buro Happold, I've never tried it, but it looks interesting and maybe suited for what you're aiming for.
Best,
Romain
P.S: If you are interested in repetition, you can also look at repetition of members (e.g. constant length) or repetition of nodes. Most of the research deals with repetition of panels, but repetition of nodes could be also interesting because they are much more difficult to fabricate than panels. Two references about node repetition: one for a specific family of shapes with high node congruence , and the other on the use of hyperbolic geometry for 3-valent meshes.

tects to overcome the imposition of prefixed architectural forms in order to enhance performance-driven design and responsive kinetic solutions that interact with humans and environment. Lectures on parametric design simulation, generative and form finding as well as environmental optimization, analyzing and digital fabrication prototyping, are integrated together in 2 main modules. Students from the beginning of the school will be divided into groups to compete on a case project increasing their ability to define project parameters, design factors, solving problems, understanding factors relationships, involving environmental and human sensors, and optimizing their projects solutions in smart and inelegance way. In the beginning of the school, parametric modelling will be introduced (Rhino3d and Grasshopper) to build the necessary skills of parametric generative form methods to students. In this module will be dedicated to digital design methods and physical model making by various fabrication techniques, including laser cutting and 3D printing. Students will focus on the idea of creating algorithmic architectural form inspired by nature and their research will be supported by a series of lectures. Also they will be split into groups in order to develop projects assigned by the professors. This Module also adds Form Finding techniques to the parametric design strategies. Students will learn how material system behaviors, physical forces and responsive structure system can be digitally simulated into parametric models in order to explore complex forms that optimized and adapted to its natural behaviors, initial forces, material, particles, and structure systems. Series of lectures on form finding, natural structural algorithms, material behaviors, and physical forces will lead student to optimize their project forms. It is experimental laboratory in which kinetic interactive Architectural models are tested and designed. Students will develop novel solutions, building upon learning responsive kinetic systems. They will design Architectural responsive robotic systems inspired by nature. Projects will transform by adapting to environmental conditions and human behaviors happening at real and virtual levels.

Amuse yourself by trying to figure what kind of series logic could deploy (or not) these room unit combos across the blue space grid shown.
2. Let's assume that surgery etc etc departments are sited in some ground floor and their requirement for rooms is variable ... meaning that some kind of heuristic GH approach must be applied here (for instance : fill the first level with rooms required by all departments with min distance from a given core and if more are required go to next floor etc etc).
The real room unit cluster looks like that (all units are prefab)
3. Voids in the whole cluster deployment (avoid Soviet type of bloc aesthetics) mean that culling could be challenge here (we need ...er..."visual" culling , so to speak)
4. After finishing some solution create custom preview(s) in order to visualize what dept owns what rooms.
5. If in trouble with Architectural things > relax > be cool > open 3d PDF > be a great Architect in just 10 easy steps.
PS: of course I know GH clusters...but as they are they violate my rule N1: never walk the walk if no return is possible, he he. But assuming that David could resolve the return issue (sure he can) this is NOT the answer for my "proposal" for multiple Canvas - again like multiple Views in any CAD stuff these days. Just imagine clusters with some serious hierarchy depth > where am I ? what input comes from what output?
I'll be back with a chaotic case (Series in complete anarchy) in order to demonstrate the critical necessity for a visual Tree Manager/Viewer (a visual thing within the GH visual thing). For manager read : decomposer, composer, visual identifier (per data item/branch) tree re-mapper, anything actually.
more soon (and a in depth analysis about what a Tree Manager/Viewer should do - in an ideal world, that is)
Cheers, Peter

for this purpose. So, without paying attention to the video, this time, this is the synthesis of the process:1. generate 3d network from points and applying tensegrity physics via kangaroo:
2. option 1: generate surfaces from network using network fillet/patch tools from GeometryGym:
3. option 2: same as option 1, but this time the network is affected by the wooly paths script in order to create the 'tensioned' curves via attraction and then creating the surfaces with GeometryGym:
4. close-up:
The goal is to achieve "option 2" without using wooly paths so that the minimal surfaces are generated as the curve network is affected by kangaroo-driven tensegrity. I want the model to be a more 'real-time' simulation instead of generating the tensioned network and doing the surfaces as a post-process. I hope that explains my intention a bit more!
the wooly paths script I'm using is the "woolier paths" one or #2, I believe.
Thanks again! I hope you can help me, and sorry for any confusions!…
m, mind). These 2 are (a) the advent of large scale 3d printing and (b) the adoption of a totally new way to fabricate carbon fiber items (I mean big things like load bearing structural members - blame Volkswagen and Boeing for that).
For instance and in a very small scale see this CF chair:
Or that:
All these mean that you/we could consider possible to design large scale things (like a "monoblock" modular hangar where the roof is fused with the columns - exactly like the chair as above and/or your initial requirement - minus the ugly basement formation).
In the mean time get the new "divine" version (2 choices : either you or God decides things concerning the "bridges").
Until next update
1. TSplines 3.4. they don't give any preview (and pipe is EXTREMELY slow) whilst 3.5 they turn components red. Karma without any doubt. Beta 4 has more bugs than Madonna had lovers.
2. Choose "God" as the placement mode and observe that the main issue here is to "fuse" properly "bridges" that potentially clash (easy for TSplines).
3. Although random is the new trend in Architecture/Design (but trends come and go) ... controlling randomly AND properly geometry is more fuzzy than it appears on first sight ( for doing something that could(?) stand(?) any future critic, he he).
4. Rhino is actually a surface modeler ... meaning that stuff that CATIA/NX do are rather unthinkable especially concerning the "frozen" state of a polysurface (Smart Surface for those in the Microstation bandwagon). You'll see why I'm saying this when this definition starts to find the right route (for instance filleting complex stitched surfaces etc etc) . On the other hand various Rhino tools are not exposed to GH (VBA/C is needed).
More this weekend.

May the Force (the dark option) be with us, best, Peter …
to do once I figured out how you use only a small portion of each of my generated curves to make the 360 degree Loft surface. I had a huge AHA! moment when I realized the complete Loft surface really only needs a small portion of the generated curves rotated around to form a closed (except for top & bottom) surface. That is a major new insight for me and I appreciate you pointing it out.
I also tweaked the Twist angle parameter a bit so the resulting positive and negative Twist surfaces, when combined, yielded a result that was closer to my original shape. This is when I discovered something very interesting.
When I baked/exported the result using just one of the 2 twisted surfaces I got an STL file that had no errors, that 3D Builder was able to simplify from a 37 MB file to a 3 MB file, and that sliced A-OK. But, when I combined the left and right twisted surfaces, I was back with my same set of problems: the exported STL file had many errors, could not be fixed, and did not slice properly.
I went back to my original layout that uses the complete set of generated curves to create the Loft surface and found I got exactly the same results - using only one twisted surface worked fine, but nothing worked when the left and right twisted surfaces were combined. By nothing I mean I tried all the standard methods (GH Join and Sunion, Rhino Solid/Union, Join, etc.) What I think this means is that the Loft surface behaves the same, and apparently is the same, regardless if it is generated by rotating strips or by using complete closed curves.
Furthermore, I am guessing the problems with the combined/exported STL file made from both left and right twisted surfaces has to do with overlapping/coincident parts of each one - like the top & bottom planar surfaces and some of the wiggly parts.
If I am correct about this then it suggests to me that there is some sort of glitch in Rhino's STL Export function. This is surprising to me since I though an STL file only paid attention to the external shape of thngs,and did not know or care about any inside stuff. Of course this is all conjecture on my part, but at least for now seems it will be impossible for me to actually print the double-twisted geometry.…
