ormation;
In fact, my plan is to try to make fabric flattening by transform 3D to 2D. I want to use VB to get shortest lines from one point to the other points in other 3 edges, for instance, there are 4 edges --> Edge1,2,3,4. Each edge to be divided to get points ie., 2a,2b, 3a, 3b...... Each point of one edge will only draw one shortest line to those points of other edges. (From picture below shortest line from 1a is 1a to 4i) and this will be repeated for all points.
Thank you,

rface and convert to mesh
2- grab the naked edges of the mesh and use the end points of those edges for my points(just the start points of the edges for this example)
3a- apply a generic unary force to those points in the positive z direction.
3b- also use the "Constrain to mesh" component to pull those points to the mesh as they travel upward.
4- start the kangaroo simulation, (boolean toggle to true)
5-use the "trails" component on the "particles out" to trace the points trajectories.
I think there is also a point trail component in firefly, but I'm not sure, I don't have it installed right now.
EDIT: I guess part of the question should also be how you are defining the movement of the point?…

* integer:
if I have three numbers, example: 3.36, 4.30, 6.87 applying an Integer filter will give me as result: 3, 4, 7. Instead I want the lowest of the two closest integers to the. In this case: 3, 4, 6.
2. make into positive numbers:
If I have a single number or a list of numbers such as "3.5, -1.2, 4, -5" I'd like to turn it into: "3.5, 1.2, 4, 5"
3. Single out specified item from grid:
If I have a grid of say 5 rows in U by 4 columns in V, like this:
ooooo
ooooo
ooooo
ooooo
I'd like to extract from the list:
3A: the first item such as this (replaced with the x):
ooooo
ooooo
ooooo
xoooo
using the filter for 1st item gives me this [undesired] result (replaced with the x):
ooooo
ooooo
ooooo
xxxxx
3B: Then I'd like to say, give me first item of last row (replaced with the x):
xoooo
ooooo
ooooo
ooooo
I'd appreciate any help with these questions.

ig0) becomes more efficient if beams are added (fig1).
The load condition on the initial T shape component is rather special: I have to generate eccentric loading in order to have the correct section forces in the component's beams. I solved this by using Eccentricity on Beam and the results is shown in fig2. This manipulation is just to have the correct section forces, in reality the beams lie in the same plane where the lines of fig0 are the center axes.
The question is how I have to model the additional beams? In reality, the additional beams lie in the same plane as the beams of the T shape (without any eccentricity).
I was wondering if I have to add some eccentricities as well in these additional beams to structurally model the whole component in a correct way. Or can I just add them with no eccentricity (like shown in fig3a and 3b)?
This is not really a technical Karamba problem, but more a question concerning a method of modelling.
I hope someone can give me some information on this.
Kind regards

x way). Why may you ask? Well ... in order to control what "module" (triangle) is where my dear Watson, that's why.
2. Your data set is wrong in the sense that you provide a single dimension list of already "ready" Breps (triangles) and then instruct the C# ... er ... to subdivide each triangle (that's like dating 123,45 girls at once: not recommended unless you are some Sheik of some sort).
3. There's several solutions to that problem:
3a: The right way is to subdivide a surface AND THEN individually modify any desired module BEFORE the C# continues post processing the modules. Any why this is a bit complex? (although achievable) Well .. the explanation is ... er ... complex, he he (GH is not designed for doing this: GH operates in a fire and forget mode, so to speak, as regards collections of things).
3b: The other way is to mastermind some (rather inefficient) way to influence modules BEFORE the C# continues ... blah blah. In plain English: using the so called attractors and the likes (I dislike that: I'm an engineer and that's not engineering by any means, but is OK for artists).
3c: The other way is to create a Plan B in the C# : don't subdivide > just get these things (as Lists/DataTrees of Breps) and compute things/whatever/US (not the land of free). But ... we need to supply the modules in an U/V indexed way (obviously we can do that automatically with "some" lines of code more - but is a very stupid way to address the issue).
PS: a DataTree IS NOT a List of List of List of ... it's an indexed collection of single dimension Lists.

ported to Rhino and "set" in Grasshopper, i trim both surfaces from their rectangular bases so that when sDivide is used it creates and distributes the same number of points on each surface.But heres the problems: a) if i use the "trimmed" surfaces with SrfGrid it errors warning: "A point in the grid is null. fitting operation aborted".I'd learned this was caused by "nulls" replacing position Data Items when the rectangular grid(surface base) was trimmed away. So i used Clean Tree which worked removing all nulls, then Shift Paths\Flip Matrix to create line-endpoint pairs for Polyline\Evaluate Curve. I Flattened the last Flip Matrix placing all data items in one source for SrfGrid, like in the working Untrim\CopyTrim definition.This time,.b) SrfGrid errored with: "The UCount value is not valid for this amount of points",.So, i substituted a 356 value, numeric Slider in the Addition B param., and tested its range until a valid UCount was found. Then SrfGrid fitted a surface thru the points, BUT,d) those SrfGrid surfaces are extremely deformed even thought the points preceding it from Evaluate Curve are accurate,SEE: def: "3b-RGH_SurfaceBlend.gh",AND,.a2) if i use Untrim with CopyTrim then SrfGrid works, but since the Jokers limbs WILL be in different surface positions then the blends between the Arm (for example) will rise from its relative FLAT position on the untrimmed Source surface to the Arm on the Target surface, rather than morphing from the Corresponding Arm position on the Source surface,. ..see def.: "4-RGH_SurfaceBlend.gh"So please let me know,..1) how to produce accurate surfaces from SrfGrid in def.: "3b-RGH_SurfaceBlend.gh",. ..(NOTE: BOTH these def's contain 2 indentical, "internalized" surfaces, but if def. 3b can be made to work it will also work with Dis-similar surfaces)2) which component to use or how else to determine the correct UCount value for a specified amount of points(ie:155), re: SrfGrid error: "The UCount value is not valid for this amount of points",.3) how else to force SrfGrid to work with Trimmed surfaces?, AND,..4) how to force intersurface, point-blend correspondence lines: Polylines(PLine) to be connected between correctly! correponding positions (Limbs) on the surfaces?,
Really! appreciate all help, definitions and kind generosity common to this knowledgable membership,
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。…
