when i type the equations for z,y,z it says a syntax error so i obviously do not understand how to construct an expression. (screen capture attached)
Any help/explanation of using this function would be greatly appreciated
thanks so much

2d grid from
grasshopper but in 3d, fully controllable of course. I want to do something
like the image in this web

I figured that connecting points and lines kind of works (point and line input AB command) but the line length changes when I move a
point. What I want to be able to do is to move a point and drag others but keep
the line segments constant, just as a real net.

ehow acquire different settings/are calculated differently. Appears at random “rows” of points, sometimes it all works fine, so I need to do a series for the error to show. See images below.
In the Ladybug fly run the VT of the window changes.
It’s taken me a day and a half to track this error down. Phew.
I get the same error on two different comps.
What is causing this? Does anyone get the same error? Images below created with RADquality set to 2, and 7 cores. Fiddling with Radsettings dont help, I think, except error goes away with very low ab.

ules and provide suggestions. It comes with some goodies useful along with SYNTACTIC tools, such as Spectral Graph Drawing and Matrix Plots. Simple connectors are also provided for SYNTACTIC and SpiderWeb. This new toolkit is in some ways fundamentally different from the version you have been using so far. For more info please check my dissertation:

if you don't have the time to read this, check this one out:
https://www.researchgate.net/publication/303944600_Spectral_Modelli...
If you want to try this version you need to install two libraries in your Grasshopper/Special Folders/Components Folder
* Math.NET (MathNet.Numerics.dll): http://www.mathdotnet.com/
* Configraphics_CS.dll (the library to be completed by me)
Please note that because this package uses Math.NET their licencing terms apply as well as those of mine. Please read the Read-Me panel in the file.
If you want to write a C#/VB snippet to do something in connection to this package we'd be happy to help you with that (as much as the schedules and other things allow us) and eventually involve you as a developer in the next versions.
Our vision for the next versions is to connect/integrate this package with SYNTACTIC and SpiderWeb.
I will replace some of the groups with better/newer modules in the coming days. Stay tuned.

50 and reduced the 'cell size' slider to 0.5. When the 'Azimuth' angle is changed to 180 +- 90 (dawn or dusk), the points are widely dispersed, reducing the density and increasing the number of cells in the "sparse grid". Under these conditions, the number of cells was ~2000 and the Profiler time for 'Boundary' went up to a full minute or more each time 'Altitude' or 'Azimuth' was changed.
So I created this code to benchmark some alternatives and found two interesting things:
'Boundary' surface performance (v.1) is not linear. As the number of surfaces goes from 1000 to 2000, the time per surface goes up dramatically.
I tried three alternatives for creating a rectangular surface at a given point that are all substantially faster: v.2, v.3 and v.4. For 2000 points, v.4 is 150 times faster than v.1 !!!
Performance of v.2, v.3 and v.4 are similar and all scale up very well. To benchmark beyond 2000 points, I recommend disabling the VERY SLOW v.1. At 5000 points the 'Pop2D' component takes ~11.3 seconds but v.3 and v.4 take less than one second to generate 5000 surfaces!
See boundary_2015Nov19a.gh attached.
So I replaced the 'Rectangle' and 'Boundary' components in my sun reflection model with v.4 in focus_2015Nov19b.gh (also attached) and the performance is amazing.
I'm sure someone has mentioned this performance issue with 'Boundary' on the forum before but as with many things, I didn't realize what a major obstacle it can be until I discovered this for myself.…

grout lines, a tile surface and tile perimeter poly line). I then use that as a Mesh (from Rhino) in the second definition.
2. I can tile out the mesh surface and rotate all the tiles in 90 deg. increments.
To get what I wanted. I took the Mesh and have copied it in series to make a grid. I can then control the dimensions of the grid. X and Y extents. I can also rotate the tiles around their centers.
The spacing of the grid is set from an edge curve of the tile (or mesh). This sets the size of the squares in the grid themselves.
See definition, images and Rhino 4 File, to give the definitions a shot. I have labeled how to use them.
My question -- how can I randomly rotate squares in my grid? I would like the deg of rotation to be random and also which tiles they are.
Also how might I rotate (every other tile) for example? So that I can control the pattern more?
Thoughts?
Thanks!

ror when it comes to points on edges of the surface.I guess it is because normal vectors at a few of points are invalid. After all, because of these invalid points, an error message comes out which is saying " Runtime error (PythonException) : Unable to add polyline to document " and it results in no output. Please give me some help if you know how to handle this problem. I post a code below.Thanks in advance.

g from a list of 12 items I would find all the combinations taking just 4 at time.
I'd use a Stream gate that takes the indexes of the items and pass them to a list item in order to select just the items of the combination. Doing so I can choose a single combination of index at time to pass to the list item.
In this moment all the data come out from the first gate, all the others are empty.
If I pass these index to the list item it gives me an error (probably because of the data structure).
*long version*
I start from a list of 12 segments, all of them with the starting point in common and the ending point distributed regularly in the space. It's a quite simple starting point.
What I'm trying to achieve is to find all the possible spatial configurations made of 2, 3, 4 segments. I started with 2 segments so I've 12^2=144 possible configurations but just 4 different configurations that can intuitivelly be recognized (60°, 90°, 120°, 180°).
Doing the same with 3 segments generates 12^3=1728 configurations and I don't know how many different ones. With 4 segments I've got 12^4=20736 possible configurations.
As you can imagine many configurations are identical but just with a different orientation so at the end I'll have to parse geometrically the output to delete duplicates (I'll address this later on).
Please could you help me to figure out how to mix these segments in different configurations?
Thank you in advance.…
