rves that "intersect" a plane placed on Z=6 above the first circle. I did this to have a collection of points from which to choose 3 and make a 3pt-circle.
[this second circle "fits" the catenary at a certain height, that's what I wanted to do]
Maybe it's obtuse but anyway that's the way I managed it.. I then used the "intersection" of the top circle with the original catenary curve to "split" the catenary into 2 parts, I then "Rail Revolution" the first part of it around the axis of the original circle, using the circle as a "rail", and I get a Brep surface.
It is a "open brep" surface, so now i'm having the problem of managing it if I want to subdivide it with Isotrim or other commands to control the number of subdivisions.
Is there a better way to go about this?
I am attaching the file.
About the image, I checked my code about 10 times to understand why it has those "lines" every 1 meter in the Z, and they already appear in the "rail revolution" component when it is visible, but in the "brep components" I can see the individual points along the rail curve.
I think this is what might be causing the brep to surface problem, but for the life of me I can't understand why the rail is not smooth and is "divided" into the 7 points instead of just one smooth revolution...
Thanks! :)

I said to myself : post (again) something in the errors/bugs category. But then I said (also to myself) : why ? everybody knows that ... post something fun(?) in the examples that can(?) guide(??) people out of the rabbit hole.
And here we are : 4 test surfaces, 4 paneling methods, 2 profile "classes", 2 orientation options, 3 methods to skin a cat, 2 methods to find intact panels (in "any" surface - trimmed or not with or without holes), 2 presentation alternatives, 7 gates, 2 filters, 1 Branch controller(?), 1 secret component (related with sardines) = let me make the maths : about 123,45 Loft examples (a bit primitive to indicate the main issue).
NOTE: GH quite frequently (a) fails to internalize data (b) internalizes them and reports the data as "null". Use Rhino file if this is your lucky day.
NOTE: Lunchbox is required
NOTE: Proper Named Views were defined ... but then components are moved ... blah blah: make your own.

思った感じになりません。
balls の代わりにplanarカーブを直接入れてみましたがエラーが出ます。
ファンクションにしてみたところ、forループので作った数値が反映されていません。
ファンクションのインスタンス?を出力していないと思い上記のようにしましたがエラーが出てしまいます。
以上の事から自分の認識が正しいのかよくわからなくなりました・・・
python自体の深いところをわかっているわけではないので余計こんがらがりました。
そこで、for b in ballsはどのような条件または使い方であれば使えるのでしょうか?
そして、上記のように別のオブジェクトに対しての使い方はどのようにすればできるのでしょうか?
2:同じファンクション内のdist = rs.Distance(self.pos,b.pos)についてですが
この文章も for b in balls によってbはBallのインスタンスであると定義?されたためb.posがbの位置であると分かるのでしょうか?
pythonは定義しなくても動いてしまうのでどのような時に使えるのか文章見ただけではよくわかりません・・・
大変細かいことかもしれませんが、よりpythonをしっかりと理解するためにも、どなたかわかる方ご教授いただけると幸いです。…
not sure why it broke down again).
I have a the following code written in C#:
namespace blahblah.Extensions{
public static class TransformMethods{
public static AxisAngle ToAxisAngleRepresentation (this Transform m){
//Implemented code here
}
}
}
I have several methods to extend Transform struct, in order to convert 4x4 matrices into different formats e.g. axis-angle representation. In this case the return AxisAngle is one of my custom structs. My desire is to script completely in Python from Grasshopper. However I cannot seem to access these extension methods from there.
I have done the following:
1) I compile "blahblah.dll" and place it in my Grasshopper components directory.
2) To test it I use a C# component and reference the dll from "manage assemblies". The C# component automatically adds "using blahblah.Extensions". I feed in a Transform struct called m and am able to call m.ToAxisAngleRepresentation() without errors. Everything is good. (except maybe intellisense doesn't pick it up the method)
3) Next I wish to do the same thing in a Python component. (Here I am still confused about referencing external libraries). I first add my bin/release folder (where blahblah.dll is located) to my sys.path.
4) Next I add clr.AddReference("blahblah.dll")
5) I add the following line:
from blahblah.Extensions import *
which I would assume is equivalent to "using blahblah.Extensions" in the C# component
6) I then test with the following code:
m = Transform()
m.ToAxisAngleRepresentation()
7) I get the following error: Runtime error (MissingMemberException): 'Transform' object has no attribute 'ToAxisAngleRepresentation'
A further question I have with Python components. If I copy my dlls into the Grasshopper component folders. Do I still need to perform steps 3 and 4?
Thanks!

Architectural Animation_ Designing National Cyber Games Center in Tehran by Using Digital Architecture Findings
Game is one of the oldest human behaviors and it is specifically related to the culture and region in every society. Considering the change and growth in societies, they –the games- coordinate themselves with these changes. Inventing digital tools, games entered a new arena and quickly changed to a remarkable area in industry and economic market and they also attract more time and audience towards themselves, not requiring big and special spaces, being accessible to public. Regarding the extensive effects of computer games on economic, cultural, educational, physical and mental health arenas, every country has done a deal with content control, supporting producers, increasing public awareness and etc within its special background. Iran computer and video games foundation as a non-profit organization takes charge of different domain support and control in this effective industry under the supervision of Ministry of Guidance. Architecture and computer games in different domains have influenced each other and are interconnected. And since games are played in one space, they require game space designing together with type of the game. So game designers need knowledge and studies in architecture design. Architecture, inventing digital tool, used its features to advance its goals, as games did. Although at first it used them for drawings and visual expressions of ideas, extending these features, they were used in design process. Meanwhile, using digital technics produced specifically for animation making and computer games leaded to their more proximity. In the design of Iran computer and video games center, we tried to use digital features in all steps. Therefore extracting main parameters from the designing process steps and changing them to computer codes (using algorithm), we tried to make its various states producible and to provide the possibility of optimizing the required area, maximum vision to key spaces around the site and also the amount of received light. Also in designing the project facade, after research on various technics of exfoliation and façade design, Media façade was used for a better compatibility with video games. With an approach to creating mobility for the audience and the computer game producers in the greenbelt near the project, physical playgrounds were created for them.…

(4)Then I made the edges rigid (like in your model):
(5) The paper deals with this in two ways, one is crumpling:
(6) The other way is curved edges:
(7) The curved edges allow for a developable shape that consits of two cone sections (joined by the green line, which is also the location of your extra fold.) Centre points are A and C.
I guess crumpling is tricky to do in Grasshopper (perhaps something for Kangaroo?),
so I would use the two cone sections to create an accurate model in GH.
Or, actually, stick with the extra fold! (A folded surface is also developable, and you've already made lots of other folds).
Good luck!…
