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.…

subsequently able to retain a higher level of flexibility.
In Rhino however a rectangle is defined as only a plane and two numeric intervals (one for x, one for y). The possible solutions to this would be:
Extend the Rhino SDK Rectangle3d type to include constant radius fillet corners. This can be done, but is a lot of work and will break the SDK.
Create a new type in Grasshopper which is smarter than Rectangle3d. This complicates developing for Grasshopper because now you have to keep two different types in mind whereas before only one was needed.
Remove the Fillet Radius input from Rectangle components. I like this solution because it results in cleaner, simpler code, but it does mean people may need to use two components where before one was sufficient.
Make the Rectangle type smart enough so that it can recognise filleted rectangles and undo the filleting. This is something I can do right now for Grasshopper 1.0 and it in all likelihood would not break actual existing files even though it is technically a behavioural change.
I'll try and get (4) done for Rhino 6 SR1, I might decide to do (3) for Grasshopper 2.0. I sincerely doubt that (1) will ever get done and I dislike (2).…

(http://www.food4rhino.com/app/quelea-agent-based-design-grasshopper) take like 40 seconds when the toggle activates to go from one end of the ramp to another.
With proximity 3d i'm analyzing each instance the agents are closer than x units. In picture 3 we can see that in 212 instances the agent are closer than those x units.
Finally all the genes that controll the ramps are connected to the G of octopus component and one of the conflicting objectives connected to the O of octopus component is the number of instance quelea agents get close.
So the thing I need is to iterate the ramps controling the genes with octopus but activating the boolean toggle (quelea run) each time the ramps are modified so the agents take 40 seconds to perambulate the environment, analyze the instance they get close and let octopus iterate again searching for a optimized environment.
…
quite know where I'm going wrong. I can say that I have successfully put together a separate file which will send data directly to the Arduino (switch on a boolean toggle and watch an LED light up... how fun:) but receiving the data is a bit more complicated. For a long time, I was getting a continuous loop error, which would freeze my app. I've changed around the code (see attached file), but I'm still not receiving any data from my COM port (which I know is definitely working because I can turn on the Serial Monitor from the Arduino IDE and see the data coming in). I did have one question: Can you call different routines inside the script class (from Grasshopper), or do you have to always call the run script subroutine? If you guys have any suggestions I would greatly appreciate it. I understand it's a bit tricky to trouble shoot this issue since you may or may not have an Arduino handy to stream the data to your computer... but let me know if you see any glaring issues with the code.
Cheers,

cy of design communication and the control of information-flow are as important as the creativity of ideas. In response to the concurrent digital evolution emerging in the architectural industry world-wide, the Faculty of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.對於高品質的建築專案,創意之外,專案過程中高效的設計資訊管理和交流成為項目設計深化和實施必不可少的環節。今天,數字化技術不但改變了建築師的繪圖工具,影響了設計的過程,而且提供了工程建造和管理實施的更有效、更高效的手段。針對建築的數位化演進,香港大學建築學院將於2011年暑假期間,在香港大學建築學院舉辦“數位化實踐”國際研習班。在香港大學建築學院教授及有著相關豐富經驗的外聘實踐建築師的指導下,學員將有機會體驗在專案的不同階段(如概念設計、設計形式的生成、優化,設計資訊的管理和交流),如何有效地應用各種運算智慧化技術(從設計的數位化生成和建築資訊類比到物理模型),提升設計實施的品質,增加設計團隊對於方案的控制。我們將挑戰對於“技術”的傳統認知,即相對於使用者它不僅是工具,更是與使用者互動的媒介,二者形成一個有機的合體。研習班期間會安排系列講座,展現數位化技術在實踐工程中的廣泛應用。…
next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

-life fabrication issues ... then ... well ... that's the reason for the Skype.
2. In general I would say that exploiting parametric "arrangements" (in the broad sense) is less than 5% of the whole ... given the fact that in real-life there's a lot of other constrains. Again using Kim's IKEA note: for instance packaging (at least for the magnitude of IKEA's business) is rather more important than ANY smart of stupid design.
3. Reliable components VS Design/Manufacturing cost IS the ultimate "fitness" challenge: this involves bottom-top design disciplines (not doable with Rhino/GH by any means) and ... well... some top dog feature driven MCAD app. Most makers/designers use the cheapo alternatives (SolidWorks/Creo etc etc) and the results ... well .. you get what you've paid for, he he.
4. Why bottom-top may you ask? (and what means this anyway?) Well ... one "connecting node" that would been made 1Z times at the minimum cost possible is a 100 times more challenging task than designing a shelve system that uses that node. See for instance A LOT of IKEA solutions (i.e. the nuts and bolts of them) that are exceptionally flimsy, very badly designed and ... well ... suitable for 1 week's usage (but there's some others that are less faulty). On the other hand IKEA actually serves the ephemeral ... thus ... this MAY be intentional (recycle > buy > recycle > buy > ...).
I buy therefor I exist.
For instance a certain IKEA mold injected "multi join node" for a given series of shelves ... it would sustain less than 5 minutes "abuse" (in case that someone would attempt to "rearrange" things). Moral: reality and theory ARE not the same thing.
I could continue until the end of Time listing "aspects" of the whole puzzle related with production issues ... but for the moment I would conclude by the following:
GH is a good "general" purpose graphic editor and Rhino IS NOT a feature driven solid modelling app. If you combine these 2 ... you can easily outline what you can and what you can't (or shouldn't) do on that subject.…
logic in the script body. Now it works OK. Feeding all the right data required to Kangaroo is entirely trivial.
Happens now : create some "filters" about if a given cone is a classic one (suspended from a triad of high points == make triads of cables etc etc) or an inverted one (pulled from the ground == do something about that, anyway). This means find some interactive way to alter the cones data tree on a per branch basis (a slider access branches > the offset is altered > cone "type" > ...).
Just checked the P thing : it's all clear now (DeBrep).
That said I work in a smoke build on some MCAD app that does the following : when you hoover over a tool ... the underlying method is exposed and ... you can find what is where in nanoseconds.
Anders: I've looked at the Brep.Trim before posting this ... but .. well I can't get the gist of it (anyway the split loop did the job).
... If the Cutter is closed, then a connected component of the Brep that does not intersect the cutter is kept if and only if it is contained in the inside of cutter....
…
ee. That said these things (masterminded by a certain David R) are not bad at all ... but if you write code that is "supposedly" transferable (kinda) to other CAD apps ... well ... I would strongly recommend the other classic nested C# collections.
2. The HLP method is one out of many: for instance for a better approximation of the required fitted plane we can use the divide Curve method etc etc.
3. GH components use (in most of cases) methods exposed in Rhino SDK > get the thingy and start digging into the rabbit hole. Of course David did some other components as well that use "less" classic SDK methods (if at all).
4. HLP is a classic approach to count the beans in nurbs curves. Of course I could use PolyCurves and recursive explosion blah, blah ... but here we are not after segments (at least at present time). On the other hand if that was a Faceted Dome (planar Polylines) ... well getting the nodes that way it could be an overkill (this means business for V2).
5. Mastermind some plane orientation policies in order to finish(?) the @$%@$ thing. For instance: Given Plane plane, define a Plane.WorldXY at plane.Origin and section these 2 > then get the cross product (sectionVector, plane.ZAxis) for the new orientedPlane Y axis etc etc (this presupposes that any plane Z axis points "outwards": use Dot Product and a center point as apex etc etc).…
