Cheetah, the CONFIGURBANIST

Hi Amir, thanks for your messages. Sorry for responding late, I'm busy with a deadline on Wednesday now. Does it work for you now?

In case of difficulties with installing MathNet.Numerics, may I suggest the following steps:

• Please install the MathNet on your system and make sure you find a file called “MathNet.Numerics.dll”
• Copy & Paste this file into your “Grasshopper/File/SpecialFolders/Components” Folder
• Make sure this dll is not blocked by your system. To do so, hover on this file and right click; go to its properties and see at the bottom of the message if it is blocked. If blocked, you will see an “Unblock” button. Push that button.
• Close Rhino & Grasshopper
• Open Rhino & Grasshopper again.

Enabling the "Memory load" from Grasshopper Developer Settings fixed the Syntactic error problem which made it not show up in the GH ribbon.

This is great Pirouz, thank you for sharing! I get this error: (I have the Syntactic 2.7 and the latest SpiderWeb installed which includes MathNet.Numerics.dll)

Hi all, is it working?

Hi, we are going to release the latest version of CONFIGURBANIST as a dll library (API) that can be accessed through C# and VB.NET components. In the meantime, I thought you could try and test the modules 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.

Hi Nadine, based on my experience, that error has most probably to do with the network being disconnected at some street junctions, so that effectively one or more streets end up being kind of an island. This is most likely invisible to eyes unless you zoom in and out to find where such problems are. Please check my posts below about potential cases (duplicate lines, lines not exactly touching each other etc.) I hope this helps. The next version underway might be better at dealing with this indicating where such problems are but in general these problems are difficult to tackle.

Hi everyone! I am trying to use the NetworkDistanceCalculator and I connected the point parameter to the attraction points as list (AttP), but when I choose the points in Rhino I'm getting the following error message  "Solution exception:Value was either too large or too small for an Int32". Can someone help me fixing that?

Hi John, happy to hear that. I could send you the individual tool but it will need adaptations to work with the old version. I will be defending my PhD (on Aula's agenda if you are in Delft) by the end of the week and hopefully soon after I will share the next version of Cheetah, which includes local between-ness and several other new stuff.

Dear Pirouz,

Thanks a lot!!!

Yes, it worked ...

Would you let me know how I can run "local betweenness" you explained in your paper " Configurbanist: Urban Configuration Analysis for Walking and Cycling via Easiest Paths"
