anually update the definition for the changes to have an effect. Also, it's not very user friendly to change data using commands (you can add them to the toolbar).
I recently did a definition that required custom attribute data per object. Since objects could vary in number it was easier to have the data attached to the object rather than in a spreadsheet. I only needed 3 or 4 values per object, so i just added them to the name of the object in the form of "a;3;500". I have the object properties window open all the time so this way it's easy to quickly change the values.
It would be great if rhino's GUI allowed to add and change custom attribute data easily. Cinema 4D does this very well. I think David was working on a plugin that did this but i doubt it's still in development.…

almost 60 seconds to compute, 50x50 points x 35 samples each x 3 rectangles = more than a quarter million curve|curve intersections), but at least not fossilised dog slow.
The inputs of the component are:
P = Plane in which to shoot the isovist sample rays, plane origin equals sample point
N = Number of rays per sample point
R = Maximum radius of sample rays. Any obstacles beyond the radius are ignored
O = List of obstacles (curves only). They will not be projected onto the sample plane, so you can have curves that are only partially 'active'.
Outputs:
P = Point at end of ray (at distance R from sample point) or point at closest obstacle along ray view direction.
D = Distance from sample point to P
H = Boolean indicating whether the ray hit an obstacle or not

orithm is very smart and elegant, many solution (like the "modulus" comand to adjust numbers bigger than 1 i suppose) will be very usefull for my next Grasshopper challenges...
Anyway i tried it and i think it's all very clear thanks also to your explanations, the only thing i didn't get is why you test the majority of the parameters of the curve with "0.5" and then you dispatch them...
What do you want to achieve in that way?
Anyway the rest it's, in my opinion, well understood and very helpfull too!
Thanks again and again!!!
Kind regards,

re are two new lines inside the code that let you deal this issue. However, the results for that type of geometry will be something like this:
I think the issue is because of some curves in crvList.. and to solve it you have to play around the start number as Michael told you.
Anyway, If you want, you can try the attached file where there is a method which should be fine for both geometries in your file: with holes or not.
The principle is to set the first number of the series component to half of height of floor (e.g. floor = 3 meters => start = 1.5 meters) and you can create a piece of workflow to do this operation automatically.

hing not acceptable. To build up the final results I tried to summarize some steps and script them but I got stuck.
1) Voronoi subdivision
2) Voronoi vertices connected to the center
3) Tween curves between center and boundary
4) Control of U and V parameters
Point 4 is really important because it will allow me to control the strength of the springs in the two directions in kangaroo. Voronoi curve is going to be an anchor and the point is going to pull the mesh.

mmed triangular NURBS surface. However, please notice that the parametrization will be small in the area of the two coincident vertices.
I'm attaching a very simple example (Gh 0.6.0059)
I hope this is helpful,

speed.
Iam using a Q6600 Quad (2.4) and 6 gb Ram with a Nvidia 460 GTX (1024) GH runs well on it but with really complex Data it takes a few minutes until u get an result.
U should get a machine with this Hardware for less than 500 Euro. But i would get a faster prozessor.

ectural project, the efficiency 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。…

ction) and apply symmetry at some point. The question is when. I would like to operate a "loft with rails", or a "sweep3". It is really important for me to stay perfectly close to the rails (outlines apex), avoiding having a polysurface or more control points. I need advises and help about the logic and order of construction. How should I tackle the problem ? I can't merge a simple symmetry into a single surface. Is it a question of degree (curves or surface) ? Thank you very much. Best Laurent
