ion of surfaces and/or "solids" : it's a very complex assembly of "components" either bespoke or widely available in the market. This demo combo summarizes the "common" cases (but the insulation for the opaque parts is WRONG 100%):
2. Contemporary trends (a bit of nonsense) point towards "liquid" forms. These ARE NOT made via "classic" linear systems. Very few actually can do it (I mean: do it yielding a building that doesn't leak]). Here's a totally wrong take on that matter from a very reputable Swiss facade maker:
And er ... hmm ... this :
3. Facade systems (curtain walls, that is) are classified in 4 classes: (a) the good old known humble stuff like the one shown in the first image (b) semi structural [yes], (c) structural [NO] and (d) planar frame-less systems.
4. Designing any proper facade is impossible with Rhino/GH: you'll need totally different software apps to do it - in real life - despite what most people believe/hope/wish.
5. Designing anything without a proper bottom-top approach (I.e. : first do the pistons then the engine) is the best recipe for not becoming (ever) a pro .…
ts connectors and slots that allow CNC machining the facets and connectors for assembly.

We developed this construction methodology earlier this year while working on a large scale parametric structure for Midburn, the Israeli Burning Man. While doing so I used grasshopper to generate the facets for the geometry, while a friend on the team (Matan Zohar) wrote a javascript app that translated the mesh into connectors and slots for CNC manufacturing. You can see more about the project here:

I wrote this component as an exercise in learning rhinoscript and python, with the purpose of bringing the functionality into the grasshopper workflow. It's now to the point where it is working for triangle and square welded meshes while outputting the connectors and slots as an unorganized list.
Questions and To Do List
1. I'm new to object oriented coding and functions, and basically just wrote the whole thing as a series of conditional loops with two dimensional arrays holding the data. Planning on restructuring this better, would love any tips.
2. Right now outputting the connectors and slots on the input mesh itself in 3D, planning on setting this up layed out on one plane to organize for cutting. I was wondering if there are any existing tools for this or if I need to do this manually.
3. Labeling connectors and slots. Is there anyway to output text from python that can be later baked into the rhino for labeling?…
tly light vehicles such as bicycles and variations thereof. Although frame design is mostly of a structural nature, there are a number of elements that interact mechanically. Also, as you may be aware, bicycle and high grade tubing is not of constant section so shelling method in FEA is out of the question, but even so, because the joint needs to be modeled very accurately, that means different geometry and properties for welded area, heat affected area and base material; like so a simpler FEA package may not suffice.
I don't know karamba extensively, rather superficially, actually, but I'm under the impression it mostly deals with beam analysis. Pls correct me if I am under the wrong impression. I must say it would be very nice to have a complete FEA package inside GH really!!
Typical workflow for me would be to model everything in Solidworks, and then export to Ansys Mechanical. Although Ansys needs to read every input and naturally remesh back again, integration within Solidworks, Catia, Inventor, Creo, Solidthinking... and the sort, works reasonably well.
Now, I don't remember Ansys having a Rhinoceros plugin so that you could bridge the 2 together, but maybe I should go check again.
3) Great work with that fractal tree. It's nice to know it is a possibility at least. I have tried Apophysis and others, but to my knowledge there's not an application that could deliver 3D fractal designs in a way that you could further manipulate with conventional modelling techniques, maybe apply textures and render, or export to CAM, 3D printing... etc.
P.S.: I have tried all the apps mentioned above and then some more. All of them have serious limitations when it comes to parametric design. For complex models they crash plenty upon rebuilding... a number of time consuming errors appear, and general work flow isn't very efficient for purely parametric work. Speaking for myself, I'd rather spend the time on a definition that enables me to have full control and then generate a new result within seconds, than model everything very quickly and then taking a long time with each new result.
(Thanks for the replies and sorry for the long text, you asked to elaborate).…
igned by this software may be terrible, this is how the future is being shaped, so an understanding of the technology is important.

-Projects are due May 8th at the WAAC Final Gallery (I think at 5:30 PM). You will have your board(s) pinned up and your physical model complete underneath. The location is still being worked out, so I will let you know when I know. After the physical submission, a digital submission is required as well. There should be at minimum -
A board with the discussed drawings and images below, named LastName_FirstName_FinalProject.pdf
A photo of your physical model (if not included on the board), named
LastName_FirstName_FinalModel.pdf.
These should be posted on the dropbox sometime before the last day of the semester. Your project will not be graded if you do not physically submit on May 8th and digitally submit sometime before the semester is over.
-Project brief is below
Project Brief: Up until now, you have been using grasshopper to develop, analyze, and fabricate architectural ideas in a very controlled format. The final project is a chance to combine this knowledge with your own design intent and aspirations. The project will use specific deliverables to spur growth, but also allow for you, the designer, to do what you please within the following boundaries.
Requirements:
# open project# must be a design project # story of what you are designing and why you are using grasshopper - specific design intent# must have physical scale model # must have 24” x 36” board - made in Adobe InDesign or Photoshop # grasshopper definition image # 1 artistic rendering - any format - with scale figures # 5 iterations of your project must be presented # 1 diagram to visually describe your project # text describing project # process drawings - photos/sketches/models/other iterations# this is the bare minimum - to have an excellent project, one must go above and beyond these requirements# talk to me if you have out of the box ideas of presenting/ teams / etc...
That is all, there are no assignments due this week, just keep working on those projects. I am available for help during the week, just email or post in the forum. USE THE GRASSHOPPER FORUM IF YOU ARE STUCK. There are many people on here that are way smarter than I that can help you.
See you all next week!…
mpression bending test apparatus has been developed to measure the flexural properties of plywood-fiberglass composite slender beams. The number of fiberglass layers and the orientation of the fibres along the strip have been examined, in order to calibrate the bending behaviour of each strip segment, aiming to encode complex 3d form into flat 2d strips, which bent and anchored at both ends, form non-symmetrical arch shapes of variable curvature. The results show that the proposed method enables a unified materially informed form finding process, where the geometry is approximated according to local material specifications at macro, meso and micro scale. Informing physics based simulations with material properties data derived from the proposed mechanical testing scheme, allowed for fairly accurate material behaviour simulations, with deviations attributed, besides the non-standardized apparatus measurements, mainly to the manual fiberglass layup and the number of mechanical tests conducted for the calculation of the mechanical properties of each fiberglass layout variation.

st shortest path. The guiding splines would work like a forcefield so that paths are "drawn" towards them with a user defined strength and radius of influence.Since each path is basically independent, it should be relatively straight forward to multithread. I downloaded the C# code for the pathfinding node and have to see if I'm up to it.
Would also be interesting to know how far away the first beta of a multithreaded GH 2 is.
I also had some hopes when "Fabric Engine" showed a demo of a Rhino exporter, since its "Canvas" is an extremely optimized node system that's fully multithreaded and optionally uses the GPU, which could be interesting to explore for some heavy lifting if they for instance would attach it to GH. But I guess it does not make much sense for them as a target.
Above image uses 20000 random points. In Softimage XSI ICE this would not be much, since it's nodes are fully multithreaded and optimized for huge numbers of particles and point deformation. In GH, with anything above 500 points, things get rather "meditative".
Illustrator takes up to half an hour after each and every change to colour, line style, blending mode etc. I have one even more complex file with over 3 GB size and there Illustrator (CS6 x64) goes into some kind of trance and after some hours of thinking moves on to some advanced psychotic, catatonic state to never fully return... ;-)So usually I run it in the background while doing something else...
I recently tried different other vector graphics apps (Inkscape, Affinity Designer, Xara) but they were even worse if they were able to open the files at all. Maybe I should give Corel a try too.
Cheers and thanks for your offer! Your work is a major inspiration for me while learning Grasshopper!

if you can't resolve the details ... well ... they do that as well. For Europe contact my good friend Peter Stevens. (BirdAir).
In general: PRIOR designing ANYTHING (at all) you must formulate some kind of collaboration with a specialized manufacturer. Problem is that ... er ... if they don't know you they don't give much attention (this is a rather "closed" AEC sector).
On the other hand if your membrane is bespoke designing the components (anchor plates, masts, tensioners etc etc) and/or using bespoke ones available in the market (not many around. mind)... well ... this IS the core of the matter. Rhino is NOT suitable for that kind of stuff by any means.
Kangaroo 1/2 is the way to go when inside GH. Other apps especially the "pro" ones are very expensive. BirdAir has the best software for that matter but is mostly an internal product available as well only for few "strategic" partners as they call Architects who can design that kind of stuff.
Other than that have some fun:

And this ... well ...is about NOT doing it:

chitecture for quite a while. I've been through all versions of 3DS Max and I've used Maya and Softimage as well. In the last 3 years though, I started using the 3D apps as an architectural design tool, but you must already know that this it not the main purpose of them.
That's when a friend of mine introduced me to GH and I was blown away by it. This is like THE perfect thing for design. I'm currently designing a high-rise for a city here in China where I live and it has a very intricate twisting, thus I took the leap and started learning GH, but I think they time it'll take me to learn it will far exceed the time of this deadline so I did the whole model in 3Ds Max, but it was a real pain in the ass moving every individual row of vertices manually, and leading myself but nothing but rudimentary techniques to make it look right, and still, it doesn't look as I want and when having to modify it, it's just another full exhausting day at work.
Anyway, that's briefly the reason. I'm hoping to learn a lot from here. If you have any essential sources (preferably updated) from where I can push my knowledge do let me know please!
Thanks!!…
ple and/or easy.
I use GH/Rhino (really GH almost exclusively) for design. I find the parametric capabilities of GH simply spectacular. The Autocad apps are all quite good (and free) so I would have no problem recommending any of them. Meshmixer is a common starter for people new to 3D printing; it is targeted at more "free form"/artistic designs that is Tinkercad, which is more oriented for geometric/engineering/architectural designs. Sketchup is also a good place to start with 3D design; it used to be owned by Google but is now owned by a 3rd party company.
For slicers I've tried them all and have settled on Craftware. It's free and available at https://www.craftunique.com/craftware. For backup to that (it is still a beta product) I use Simplify3D (very seldom) but it costs $150.
If anyone cares I have uploaded an updated version of the Stepwell GH file; I tweaked it a bit to make it a little simpler and to make the base thicker so it would be more robust when printed. The dimensions of the part are large so it has to be scaled down to fit a particular printer. This is easily done with any slicer. The STL file from Rhino still has to be fixed; as exported it would print with no bottom - and I haven't figured out why that happens.…
