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).…
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,

as the design table? I think this could be 'drawn' and constrained in Inventor in a lot less time. I know the GH model would have a lot of flexibility, but in this case, what can you do with it that wasn't provided by an Inventor model?
Only the 27 lines mentioned were modeled in Rhino, the rest is modeled with GH.
The 5 hrs involved thinking about the approach, defining vertical lines, tilts, elevations, pitch of the roof, intersections.
Once I had decided what my approach would be, and tested the logic with those first lines, points and data path arrangements, it only took one more hour to get to this:
Which is actually quite fast, compared to MCAD workflows.
If you already have components (columns, beams, etc.) modeled and ready to drop into a project, of course it is lightning fast to model simple projects like this example.
I am not as much interested in those situations, because improving efficiency is straightforward and obvious.
I'm more interested in situations where there are no pre-defined families of objects, in which case you need to start from scratch.
The GH model I'm showing is modeled from scratch, except for the 27 lines in Rhino.
Here's one obvious advantage to modeling with GH, once the definition is set-up, it's virtually effortless to change inputs and alter the overall design. Here's an example, lets say we wanted to extend the roof 3 more units, curling away from the original direction.
Plan view before:
And after:
An MCAD app will also allow you to do this, as long as the location of additional elements follows the existing geometric method of definition. What happens if you want completely change the way you locate columns, roof slope, intersection points?
In MCAD, you'll need to re-model the underlying geometry, which will take the same effort as the first round. In GH, this process is not only much faster, it's open to algorithmic approaches, galapagos, etc. and it just takes some simple re-wiring to have all down-stream elements associate themselves to this new geoemtric definition.
For instance, here's the same definition applied to two curves, which are divided in GH, the resulting points are used as a starting point for lines directed at normal from curves.
This is not so easy to do in MCAD.…

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

ject that involves the design of an app that allows people to interact with a 3d model through some sliders.)
Ok, imagine you have a symmetrical shape like the one i drew:
What I intend to do is to have different 3 sliders that allow me to adjust the 3 distances (x, y, z) independently of one another.
-1st question: my idea is to draw the curves in rhino, then use the "divide" and "list item" components to extract the points I need. Is it correct? :D
-2nd question: the "move away from" component can be used in a symmetric way?
(I try to be more specific: with only one slider, can I move both points 5 and 6 simultaneously about the axis i drew?)
-3rd question: is there a way that allows the curves to reshape themselves as I move the slider related to the distance between a couple of points?
I hope I have been clear ;) I would greatly appreciate any help you can give me!

dro). The quality of the driver is also critical: hard to imagine NVidia working overnight to fix "some" driver bugs due to requests from gamers. Game cards are notoriously bad in dual monitor configurations.
3. A zillion of cores (triumph of marketing VS common sense) divided by the given clock rate ... gives you just ONE poor old core (Rhino/gh are single-threaded apps) that tries to do the job.
4. Single Xeon E5 2xxx V3 (the higher the clock the LESS the cores = better) would be my recommendation. ECC fast memory is also a must.
PS: Find a friend who operates a "loaded" H/P Z840 and test your defs.

nd me to kill him but give him my regards anyway) is still around in BirdAir Italy ... talk with him.
3. Hope that you understand that designing the "details" means some decent MCAD app + FEA + this + that. "Fusing" this with some abstract graphic editor like GH ... is ... er ... impossible (in real-life, you know, he he ). Generative Components on the other hand may qualify but requires a lot of time in order to fully master it (approx 2-4 years).
4. FormFinder ... well ... that's utterly Academic but on the other hand ... (good luck).

My realistic (low cost) advise:
use K1/2 (especially if you are after "parametric" exploitation(s)) ... and then diversify tasks: stuff for the structural department, stuff for whom claims that he can(?) design the "details" ... whilst be in a constant contact with the membrane provider (and in fact: the contractor for doing the real thing as well)

which almost works...
I have 5 integer values in one string:
- When my input is the string "(25,0,0,0,175)" it is not assigned at all
- when my input is the string "25,0,0,0,175" it is assigned as 25000175 :)
- when my input is the string "25|0|0|0|175" it is assigned as 191 which is completely confusing :)
Can anyone point me into correct syntax of input string to be correctly parsed as a set of integers? I'm accessing Rhino+GH from external app so I can format the input in any appropriate way, yet I cannot directly modify the GH script that uses these Integer Parameters as a way to handle input.
Regards,
Boris…
