your surface in order to do it with more control points, these new points will be attracted by curves and moved on z by a factor depending on distance from curve, changed by graph mapper and by a constant thickness. This will give you 2 surfaces, one unchanged an another on the top. These surfaces will be closed by lofting their edges and joined.
The closed surface will be meshed and send to bowerbird waffle.

pper, it appears that half of the surfaces are now flipped (normals now pointing to the inside of the polysurface). I've tried to use a guide surface, I tried offsetting points along the normal to test for inclusion and then flip. I've even tried to flip normals manually by mutliplying the normal by -1.0...no matter what I try, can't seem to get all surfaces to be in the same orientation. Any insight would be appreciated...

here's an image of what i get when i do the dir command in rhino:
here's what i see when i display normal vectors in grasshopper:

akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

intersection-elements (01/AA etc)
To get a result from RInt i do have to flatten the first set and do have to graft the second. Therefore i can only retrieve the parent-information from the second set.
I hope i could explain my problem and somebody has an easy solution on hand...
Best regards,
Heiko

by arch.tualize and AWARE in partnership with the Städelschule Architecture Class (SAC), Frankfurt and will be held at the campus of SAC from 21 July – 1 August 2014. The lab engages students, architects, designers and game developers with four techniques of prototyping: designer-informed, analytics-driven, crowd-operated and sensor-actuated. Participants learn to use digital and parametric design tools and engage with feedback collected from simulation algorithms, online users and real-world sensors. The acquired knowledge will be applied to designing interactive prototypes ultimately exhibited at an open public exhibition at the Städelschule

ty lots as extrusions with their height depending on perimeter length. Then I added a 'Cull Duplicates' group to avoid properties that had duplicate 'Area' centroid points. That reduced the number of properties from 364 down to 331, though five of those have 'Area' values between 88 and 205, ten have values less than 500 while the average is ~1.3 million!
So the data is still suspect. Some appear to be nested inside of others? But using those 331 properties, I now find 32 that intersect the 'Zoning Districts'. But that's not the same as a list of properties that span two or more 'Zoning Districts'... Not having fun anymore. :)

ts. Ideally, I'd like to set the exact number of points populating the region, ie 211 in GH = 211 visible in rhino.
(I was able to achieve the exact number of points using populate2d instead of sdivide, but could only get this to work with a simple rectangular region)
2) After I have exactly 211 points, I'd like to populate each of the points with a block made in rhino (for example: the stick figure man seen in the view)
(One idea is that I build a dummy geometry and replace later with my block in rhino. But how do I make this change universally over the 211 points?)

stepper motors with an arduino DUE ( 84 MHz clock) so would be faster than an UNO (16 MHz).
The problem : The DUE is selectionned, detected and I can open the port in grasshopper, but when I try to send any mouvement with the stepper component.. isn't moving at all.
Also when I try to read the serial monitor with the generic serial read component is also not reading anything coming from the due card (I tried the programming port and the USB communon port from the DUE).
To now : Sending mouvement with the Accel Stepper library directly with the Arduino IDE works, Wich means that the problem is directly coming from the communication between the Firefly's Grasshopper component and the arduino Due
The due : www.arduino.cc/en/Main/arduinoBoardDueThanks for your time :-)…
