s the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?
Secondly:
Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.
1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.
The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...
I do not understand where the mistake is in this definition...
Thx in advance1

l use Rhino 4.0 and corresponding GH version, as a result i could not open your Rhino file.
Hence in your definition as i see,
1) Spring Force-1 -Connection has 11 'inter' components. The inter components do not have any input data and hence 'orange'. What are the inputs for 'inter'?
2) Spring Force - 2 -'Connection'has 1 point component. Rest length & Cut off has 'mass addition' data. This force is also orange, could u throw a light on this please?
3) Pull to surface - both forces has no point input, hence it is orange too. could u throw a light on this too please?
4) There are 2 x Cartesian product components not connected to anything.
I realise that partially it could be because i'm using lower version of Rhino. However, ur input will be highly appreciated.
Kind Regards,

each circle's border, let us say 1.0
3) So, the curve will end up with 5 points, in each point will have a circle, each circle will have a different Radius, but the distance in between the borders of each circle is always the same = 1.0 in this case.
4) The end result list here would be like this to evaluate a curve with these values and find the points on the curve:
List = 1, 5, 11, 19 etc If I use these values to eval a line, I will get the perfect points where I can draw the circles.

e now contains (40x3x11=)1320 points with a branch structure of {0-39,0-2} i.e
{0;0}
{0;1}
{0;2}
{1;0}
...
{39;2}
with each branch containing 11 points.
I now want to create lines from the points on line {x;0} to {x;1}, {x;1} to {x;2}, and {x;2} to {x;0}, which will give me a triangular grid on each triangle. How do i do this? I think I need to split the tree 40 times to give me 40 single layered trees but I imagine there's a cleverer way of doing this!
This feel like it should be simple, but I;m having trouble working with the double-layered branch structure. Any help would be greatly appreciated!
Thanks,
Matt…
keep the same number of branches.
The way I'm doing it now has the inconvenience of only working for this particular number of branches, and I would like a more general way. Do I need a script or can I solve it with components, path mapper, etc?
-Also, and this one is probably simple but I can't seem to figure it out: I have a tree structure as in fig B, and I want to pick out certain series of branches from it, for example {1;0} to {2;11}. (PathGen seems to only go from {0;0} to a specified item?) So I want to be able to plug in a choice of numbers, and dispatch those branches into separate trees/cull them somehow. What am I missing? In general, I've failed to find a way to pick out all of the "uppermost" level of branches, eg {3;x}.
Any help greatly appreciated!…
r-workshop programme will focus on the design and 1:1 fabrication of an interactive pavilion for the 2012 International Festival of Electronic Language (FILE). Located on Avenida Paulista, the pavilion will react to light sensors and human activity, so as to transform and create a range of different lighting and spatial effects, triggering further movement and producing an interactive feedback loop of behaviour and response. To accommodate this responsiveness, the design should be developed using recursive scripting, associative modelling and digital fabrication.
Each workshop will focus on a different phase of the pavilion’s design and construction. Instruction will be led by Rob Stuart-Smith of Kokuggia and Tristan Simmonds of Simmonds Studio, with Lawrence Friesen of Generative Geometry, Anne Save de Beaurecueil and Franklin Lee of SUBdV, together withand other AA tutors, as well as local structural engineers and set-designers. Each workshop will offer introductory instruction in computational design - Grasshopper, (GECO, Firefly) and Arduino, and digital fabrication, while advanced instruction will be offered to participants undertaking multiple workshops.
Workshop 1 will develop design variations in small models, as well as material and structural scale modeling, testing and initial 1:1 prototyping, following computational and digital fabrication instruction. Workshop 2 will produce 1:1 prototyping. Following computational and digital fabrication instruction, it will explore the mechanics and electronics of the light-sensors and motors that generate the transformations of the pavilion. Workshop 3 will fabricate the final elements, working directly with manufacturers, testing partial assemblies. Advanced development of all circuits and Arduino scripts will take place following computational and digital fabrication instruction. Workshop 4 will focus on the final assemblage of the pavilion on site.

Target group The workshop is fully funded and is addressed to students of architecture and civil engineering faculties at master level from Estonia (11 seats), Latvia (3 seats), Lithuania (3 seats) and Sweden (3 seats). The selected students will have full scholarship that will include travel, board and lodging in Tallinn for 10 days (arrival on Sunday 03.07.2016 departure on Wednesday 13.07.2016). The workshop is funded by the NORDPLUS programme of the Nordic Council of Ministers (NCM) - Higher Education objective.
Description The use of digital and computational design tools is increasingly important for the activity of design and research for architects and engineers. It permits to integrate environmental and energy aspects from the very early stages of the design and planning process to achieve more performative, efficient and integrated buildings and urban environments. The workshop attendants will broaden their design and technical knowledge with solar design, daylighting and energy efficiency topics and will learn how to integrate environmental analysis and building performance analysis tools with parametric and generative methodologies in architecture and planning.

ay be other issues with your geometry, but this is usually the issue people run into.)
Rays will lose energy much more slowly when a room is very reflective, but such conditions only really exist with polished painted concrete. I don't know how many such rooms you've ever been in. I can count them on one hand - and I've been to acoustic reverberation chambers on 3 continents.
Pachyderm works with a ray decimation algorithm. This means that a ray will be traced out to the cutoff time, unless it has lost enough energy that its further contribution to the impulse response is negligible. At this time, the ray is discontinued. So, the more absorption in the room, the less time it will take to run the simulation. So, more realistic absorption coefficients will allow a model to run in a more reasonable amount of time.
Gypsum board/Plasterboard will typically be between 8 and 11 percent at mid and high frequencies, and higher at low frequencies, for example. Concrete, unless polished and painted, is still a little porous, so you can probably make it 3 to 5 percent.
Regarding sources and receivers, adding more receivers adds almost nothing to calculation time (until the every end, when it extrapolates a pressure response, anyway). This is because the receivers are entered into a spatial partition system, which allows it to be done in an optimized way. Adding multiple sources will effectively multiply the calculation time by the number of sources, because the simulation needs to be repeated for each source individually.
Hopefully this helps you figure out how to run simulations with reasonable run times.
