ectly in grasshopper (drawing a curve on top of a line with different angles), i did the curve shape in rhino and import it into grasshopper.
i'm having a problem where some of the sine curve shape can orient or map onto the triangle surfaces nicely, but some of them do not. whenever i try to orient the shape onto the bottom portion of the icosahedron, the shape becomes 'negative', forcing me to flip the lines before offsetting and patch (i am using loft method) or else it will become a weird loft (image 3).
i have tried several different ways to orient the ones that worked (orient 3d in rhino, rotate 3d etc.) and still could not get them to work.
the reason that i want them to face in the same direction is so that i can use WB thicken and make sure they extrude in the same direction. i have tried to unify the normal faces in grasshopper and still it is not working.
does anyone have any idea why or how can i do this? your help will be greatly appreciated. i am fairly a beginner in GH so if there is any other easier method to do this will also be great :)

o be used for the subsequent energy simulation by using customized csvSchedule, as shown in Fig.1.
For each lighting group, there is a separate lighting Power Density (i.e. 14.57, 14.57, 9.7619 W/m2 respectively), as show in Fig.2.
Fig.1
Fig.2
Fig.3
My question is:
What is the correct way to plug the "three lighting schedules and lighting Power Densities" to the "setEPZoneLoads" and "setEPZoneSchedules" components, making sure Energy+ can recognize and use these schedules and LPDs for calculation correctly?
As indicated by the panel in Fig.1, three csv files should be generated, but I can only see one csv file (in attachment) generated in the indicated path. It was generated based on the third branch data (i.e. the third 8760 list) of the input "tree" data, instead of the data in all three branches.
As indicated by the panel in Fig.2 and 3, there is only one LPD value (i.e. 14.57) or lighting schedule shown in the yellow panels, instead of three. Is that normal?
Thank you in advance for your kind help!

via MIDI controllers.
my idea is to link PureData to GH via UDP. why pure data? cause' i can relate data like GH to generate numeric relations (and link it to audio generation)
so far i got PD and Processing to talk, but i can't get to grasshopper.
i use this definitions to make pd and processing to talk http://ubaa.net/shared/processing/udp/ and this GHX to get the data to GH http://www.grasshopper3d.com/forum/attachment/download?id=2985220%3...
i got this data from this post but the GH definition doesn't work for me. i have tried LAN definitions and "the engine" as well but they both freeze, even if i send data thru processing or PD.
i have a lot of questions at this time
1.- why processing tells me that i am getting the data from diferent ports, while i'm using 6000?
2.- why in the UDP definition i get no data out, even if it should say something like "waiting fordata/port/etc.." that's defined in the C# capsule
3.- is there a direct way to get midi data (key and CC) to GH
i also tried to use firefly to get the data via COM port. i know you can do this trick in processing but i just don't know how.
well. if anyone could help me i would share the results here (since it's a magister, results shoud be very interesting)
UDP has allways been a unsolved issue on other posts. maybe we could work it out ;)
Thanks…

This year's Challenge is entitled:BUILDING THE INVISIBLEInforming Digital Design with Real World Data
THE PREMISEVast streams of data offer a rich resource for designers. By incorporating external information into our design processes the autonomy of the design is challenged. User data, energy calculations, embedded sensing, material and structural simulation, human behaviour and perception, particle flows and force fields allows design to be situated and responsive. From the simulation of megacities to the solid modelling of material systems, design has the potential to be informed by the real. Design sits not separate from is environment but inhabits an ecological system, open, dynamic and interdependent, diverse, partially self-organising, adaptive, and fragile. Across scale and within time we now have the chance to instil architecture with an immanent intelligence creating new relationships between the user, the built and its ecosphere.THE OPPORTUNITYSystems theorists suggest that data is only a raw material. It can be differentiated from information, knowledge and wisdom. Understanding is multi-levelled: understanding of relations, understanding of patterns, understanding of principles. As digital designers our challenge is in harnessing the power of computation to assist us in informing our design process. Computers help us collect, manage and analyse the environment and inform us about an abundance of data. Our challenge is to use these inputs in a meaningful way to help us make better informed design decisions.THE AIMSG 2011 explores how the incorporation of real world data challenges existing design thinking. The SG 2011 workshop aim is to create physical prototypes of design systems to be exhibited in the SG2011 exhibition.
The SmartGeometry Group is a not-for-profit educational organization dedicated to the use of computational tools in architecture and engineering. SG brings professionals, academics, and industry together to explore the next generation of digital design. SG Workshops are non-platform specific, believing it is the methodology, not the tool, that matters.

what they really mean by that, as in what buttons to push, so I assume it's a Windows Path entry?
2.) Modify PATH
Add the install location on the path, this is usually: C:\Program File\IronPython 2.7
But on 64-bit Windows systems it is: C:\Program File (x86)\IronPython 2.7
As a check, open a Windows command prompt and go to a directory (which is not the above) and type:
> ipy -V PythonContext 2.7.0.40 on .NET 4.0.30319.225
Tutorial on setting a Windows environmental variable (path):
http://www.computerhope.com/issues/ch000549.htm
But this fails to point out that path contains many entries already separated by semicolons so if I merely add a new variable called "path" it's likely that I will destroy existing program function. There's no info on how to just tack on another entry, and the Windows 7 edit box doesn't even show the whole collection, but one item (!), so I copied the existing path into a text editor to see the whole collection successfully and added the C:\Program Files (x86)\IronPython 2.7 entry after an added semicolon, correcting for an Enthought page typo of no 's' on the end of "Program Files". I also checked the others and many pointed to old missing directories so I deleted those entries.
...and the test fails and "ipy" is not recognized as a command, even though the path now shows up using "path" in the Windows CMD window, that is if I copy all by right clicking and pasting the stuff into a text editor to really view it all. I can run it from the source directory just fine.
The rabbit hole was indeed deep. Using the Task Manager (control-alt-delete) to kill Explorer and then Run in the menu to restart "Explorer," along with restarting the Windows CMD window however, worked. I can now invoke Iron Python ("ipy") via command line from any directory. For the "path" I edited path in the System Variables and not the User Variables. No, you don't have to type that whole crazy line above just to test the path variable, just "ipy" (and control-Z to quite IronPython) in the CMD window invoked by typing "cmd" into the Start menu search box.
From the CMD line this step did work fine:
3.) ironpkg
Bootstrap ironpkg, which is a package install manager for binary (egg based) Python packages. Download ironpkg-1.0.0.py and type:
> ipy ironpkg-1.0.0.py --install
Now the ironpkg command should be available:
> ironpkg -h(some useful help text is displayed here)
But of course Step 4 fails, giving pages of what seem to be error messages;
C:\Users\Nik>ironpkg scipy
Traceback (most recent call last):
File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\enstaller\utils.
py", line 92, in write_data_from_url
File "C:\Program Files (x86)\IronPython 2.7\Lib\urllib2.py", line 126, in urlo
pen
File "C:\Program Files (x86)\IronPython 2.7\Lib\urllib2.py", line 397, in open
File "C:\Program Files (x86)\IronPython 2.7\Lib\urllib2.py", line 509, in http
_response
...
Why can't I just download Numpy as a normal file and thus also have it easy for other users to install it when they use my scripts? This is just crazy and lazy. The Enthought developer has turned this into a computer game, with a missing registration link and then the last step spits out errors with utterly no information on how to fix it manually.
This Step 4 error is covered here:

make quad mesh usable with Kangaroo and with limited inputs parameters in order to simulate funicular structures like "Vaulted Willow" or "Pleated Inflation" from Marc Fornes and the Verymany.
Here is a first attempt script.
As inputs there are :
Lines_in, just lines, no duplicates, on XY plane could have Z values, but the algorithm works on a , on XY plane could have Z values, but the algorithm works on a flat representation.
Tolerance is used to glue lines when points are closer than tolerance
Width is the half width of the “roads” going through the network
Angle is the shape of the ends of the roads, 0° means flat end, 180° a totally rounded end
Deviation is the shift generating spikes or enabling to generate pleated geometry
N_u is the number of subdivision along the “roads”, image above with 3 subdivisions on the roads
N_u is the number of subdivision across the “roads”
Zbool if false everything is flat, if true the mesh is in 3d, best with angle = 180° or -180°
For the outputs there is the topology of the network (like Sandbox)
As outputs geometry are put on datatree, each branch represent a path on the road, above 3 paths, which are brep output.
Adding a diagonal there are now 4 paths so 4 branches
The mesh M goes with F which are fixed points, anchor in Kangaroo.
U and V are lines in datatree, there will be used as spring in Kangaroo, U above
This script could be used to draw sort of roads, like in here https://codequotidien.wordpress.com/2013/03/22/hemfunction/
But the primary purpose is to do that.

curve or locus] of a segment AB, in English. The set of all the points from which a segment, AB, is seen under a fixed given angle.
When you construct l'arc capable —by using compass— you obviously need to find the centre of this arc. This can be easily done in GH in many ways by using some trigonometry (e.g. see previous —great— solutions). Whole circles instead of arcs provide supplementary isoptics —β-isoptic and (180º-β)-isoptic—. Coherent normals let you work in any plane.
Or you could just construct β-isoptics of AB by using tangent at A (or B). I mean [Arc SED] component.
If you want the true β-isoptic —the set of all the points— you should use {+β, -β} degrees (2 sides; 2 solutions; 2 arcs), but slider in [-180, +180] degrees provides full range of signed solutions. Orthoptic is provided by ±90º. Notice that ±180º isoptic is just AB segment itself, and 0º isoptic should be the segment outside AB —(-∞, A] U [B, +∞)—. [Radians] component is avoidable.
More compact versions can be achieved by using [F3] component. You can choose among different expressions the one you like the most as long as performs counter clockwise rotation of vector AB, by 180-β degrees, around A; or equivalent. [Panel] is totally avoidable.
Solutions in XY plane —projection; z = 0—, no matter A or B, are easy too. Just be sure about the curve you want to find the intersection with —Curve; your wall— being contained in XY plane.
A few self-explanatory examples showing features.
1 & 5 1st ver. (Supplementary isoptics) (ArcCapableTrigNormals_def_Bel.png)
2 & 6 2nd ver. (SED) (ArcCapableSED_def_Bel.png)
3 & 7 3rd ver. (SED + F3) (ArcCapableSEDF3_def_Bel.png)
4 & 8 4th ver. (SED + F3, Projection) (ArcCapableSEDProjInt_def_Bel.png)
If you want to be compact, 7 could be your best choice. If you prefer orientation robustness, 5. Etcetera.
I hope these versions will help you to compact/visualize; let me know any feedback.
Calculate where 2 points [A & B] meet at a specific angle is just find the geometrical locus called arco capaz in Spanish, arc capable in French (l'isoptique d'un segment de droite) or isoptic [curve or locus]
of a segment AB, in English. The set of all the points from which a segment,
AB, is seen under a fixed given angle.…
