s up to one closed surface at top How could I possibly do that?
2) I also tried to divide the surface into two parts then I could set up two different UV grid, in this case I used hexagon, for the further development. Splitting them was fine but when I tried to create the grid individually, it seemed created a grid across the original surface before splitting which it leads to lots of clear up job in ther furture. Can anyone help me with that? Thank you

achieve this. If any one knows of an examples please let me know.
As my current understanding of the maths behind controlling a curve is limited I'm not particularly confident in referring to such things as control point weights and knot vectors without causing confusion. However what I had envisioned was a solution where certain parameters were fixed, such as the start/end point, length, control point weights and degree of the curve. With enough of these parameters fixed you would define an area of possible manipulation for the control polygon of the curve and the curve itself. Possibly you could play with a couple of the variables to further increase the area of manipulation.
Sorry for the poor quality of the sketch and photo, hopefully it goes some way to showing my intentions.
If A and B are fixed to the same position in both 1 and 2 and the curve between them is the same length in both instances I wish to restrict the editability of the control polygon to preserve these characteristics.
My current thinking is that I'm going to need to rebalance the nurbs curve definition so the set parameters are one side of the equation and the available ranges on the other side. I had also considered a scenario where you set control points and iterate to a specified tolerance for the length of the curve. I've not made much progress in either direction but i thought it would be interesting to hear some other views on the best way to go about solving this or have someone highlight on obvious or simple solution I've overlooked.
Cheers for any input, as/if i make any progress ill add to the post.

that, I have a few more comments on what you are trying to do:
1. It is not possible to divide the surface of a sphere with regular hexagons [the most efficient way includes pentagons as well (classic soccer ball)].
So I believe that in the image you posted there is some serious twisting taking place at the back side (you can actually see this starting on the right side of the picture).
Lunchbox's [hexagon cells] component divides the surface in U and V (orange slices for a sphere) and draws hexagons on it. The result is some serious deformation on the 2 poles and many non-planar cells. If you are ok with this, then my only tip would be to use an even number for the U divisions in order to have a clean seam:
instead of:
2. The hexagons you have defined in 2d are wrong as they are overlapping and also leaving gaps between them:
You should define your hexagons so that they form a honeycomb pattern. It could be something like this:
3. There is no direct way for hexagonal mapping, so your best bet would be to draw your pattern inside each cell (good GH data structure understanding is crucial for this). Also, the non-planar cells will probably give you a hard time there...
Hope I cleared some things and didn't cause more confusion!

division Points) is the first, the intermediate or the last and then they add the vectors (v1 for the first adjacent face, v2 for the other) depending on the even/odd index. As you may know: point + vector = a new "shifted" point. Flipping the v2 vector (the last boolean in the C#) allows you to viz the angle between the 2 adjacent faces (per edge).
To tell you the truth ... for me ... well .. the above few lines are far easier (and way faster) to write than the "equivalent" thing with components. Blame the Dark Side I guess (and ~500+K lines of code).
Jokes apart:
Thicken a given freaky crenelated Brep Face is not that easy: a teeth needs some space for the glue AND the sides need to be "tapered" in order to fit perfectly each other. Meaning: an offset for the crenelated closed Curve AND an other crenelated Curve (at the bottom). Then you join the Lofted Brep between the 2 Curves with the 2 planar Breps (top-bottom).
Additionally: well ... try to imagine "inserting" pieces into an already assembled combo > glue would do what glue does AND if the vault is made, say, from plywood ... well... an aesthetic disaster is asured
If the plywood is treated with some proper penetrating oil (AVOID varnish AT any cost) ... then the oil would "contaminate" the sides and glue won't work.
Other than that, I predict lot's of broken teeth (in the "sensitive" areas) not to mention broken nerves.
Here's me admiring a "similar" experimental vault that I made a million years ago:

er the facade panels of the residential building showing how private or not private is the overall shape. All the views will come from the office tower to the residential tower
My inputs on the view analysis component are 10 points for each of the office floors/facade perimeter (50 floors) for a total of 500 points. An aproximate panelization of the residential building facade (2220 panels) to perform the analysis on. And the center points of each residential building facade panel
The problem that I am having right know is that when I start the calculation the computer stops responding, but I dont know what I am doing wrong. Also I dont know the criteria in how to set a proper "_gridSize_" and _disFromBase for the scale of my analysis and my rhino units which are in milimeters in correspondence with the logic of how the view analysis component was made.
Attached is the grasshopper file, with data internalised.
Thank you in advance!!

2. It will be wrong if lines go through inside of the circles and obstacles.
You can replace circles and obstacles with points and lines.
3. Take the Distances into consideration.

pavilion) and from that i want to fabricate it using some paper or card bored .
for modeling the pavilion i used a simple kangaroo based algorithm to generate the desired form using mesh 3d plane faces . there was no problem with this part and i was able to get the mesh from geometry out put . then i wanted to use that output mesh to panelize it and then adding tabs and the nesting and cutting to get the parts. but the problem was every tutorial i looked up were using surfaces to panelize and nest so this was the first problem to convert the mesh into a surface and then panelazing and nesting . i tried using the mesh2nurbs but it didn't work out for me . (because i needed a single surface not some poly surfaces) . (attachment | input mesh )
so i started from the beginning and tried using a surface as an input for kangaroo and thus getting a surface as an output so i did that and tried to create a surface by the Surface from points component . and the result was not good the surface was kinda messed up and the the reason was the points were not ordered well i guess . so this was another problem for me . (attachment | input surface)(picture below)
so basically i have a few main questions :
1. is there a tutorial or any topic or book or somthing that explains from 0 to 100 from design to fabrication (as an example a pavilion) ?
2. can i use the mesh to panelize and nest and then fabricate ? and are there any tips or tricks to it ?
3. is the starting from surface for me a good idea or not ?
i am extremely sorry for talking this much and i'm grateful for the time you spent on reading this .
best wishes ; Babak.

This program can determine the quantity of energy which passes through a Radiance geometry, using the ray tracing method. (quite powerful program !!)
Unfortunately, when I want to run the program it says "can't load the Radiance input"
(Windows 7 & Radiance version : 5.0.a.8)
My batch file is :
@REM DIVA for Grasshopper Illuminance Batch FileSET RAYPATH=.;C:\DIVA\Radiance\lib;C:\DIVA\Radiance\bin;C:\DIVA\DaysimBinaries;$RAYPATHSET PATH=.;C:\DIVA\Radiance\lib;C:\DIVA\Radiance\bin;C:\DIVA\DaysimBinaries;$PATHc:cd C:\Users\shuet\Desktop\Test_fonctions_Radiance\batch04

C:\Radiance\bin\genBSDF.exe +f +b -c 500 -geom inch blinds.rad > blinds.xmlpause
Do you have any idea about what is wrong with my batch file (or the program ?) ?
Thank you in advance to help me,
