Dear Pirouz, congrats for your great job.

I taked these graphs from your google site and your SSS9 paper, and...

@ Gabriel Bremer:

Additionally, I could also suggest using a genes generator from GH to change the areas of the bubbles so as to deal with the issue of big coins.

BTW, please note that if you don't get a beautiful graph drawing, it does not mean that you cannot use the Space Syntax analyses. the drawing of a graph and the graph itself are not the same thing.

Hi Gabriel, 

Thanks for your compliments! 

Regarding the bubble diagram:

The issue could be one of the followings or a combination of them:

1. The configuration graph might be non-planar, that is, a graph that cannot be possibly drawn on  a piece of paper without its edges crossing one another. Please check this Wikipedia article: 

https://en.wikipedia.org/wiki/Planar_graph 

2. It could be that you are trying to fit a big bubble in the middle of small bubbles, imagine trying to fit a 2 euros coin in the middle of 4 5 cents coins. This is a coin-graph (alias kissing disks algorithm)

The remedy that I can suggest right now is to lower both the attraction and the repulsion coefficients in the Force-Directed graph drawing component. that way you should be able to get a 'better' drawing. 

For the next version, we have made a series of new components that ensure arriving at a planar configuration graph. Stay tuned for updates. 

I hope this helps for the time being.

Hello! Congratulations on the beautiful work. I would like to ask some basic questions that came up in my first contact with Syntactic.

1-I started with a complex organization in my first test and could not generate the bubble diagram. It turns red with an error alert. I tried to break it up into smaller pieces and it worked again. Is there a limit on connections?The sequence that binds the points interfere with the result? Why do bubbles overlap? View files: scheme with many connections.gh and scheme with many connections.3dm

Rhino file

Gh file

2-Some areas have priority of connection. How can I configure this?

3-When I move the dots and the curves the bubble diagram changes. Why does it happen?

MOVE CURVES AND POINTS CHANGED THE GRAPHIC

Hi Esteban, I believe the mistake is copying the exe file into the components folder instead of the extracted GHA file. Please redo the installation, specify a location for the containing folder, then find the green .gha file, make sure it is unblocked, copy it, and then paste it into your GH components folder. After that Restart your Rhino and GH. I hope this solves the problem. Happy 2018!

Hi Pirouz, I have the same problem mentioned by Francesco. I followed the installation procedure step by step with no success.

Comment by Pirouz Nourian on December 27, 2017 at 3:14am

Hi Francesco, the exe file is only to extract and make a folder containing a GHA file and example files on your computer. During the installation process, you can specify a location you know (e.g. you desktop) and then copy the GHA file from that location and paste it into your GH/Components Folder. Could you please verify that an unblocked GHA file is present in your Components folder?

Best wishes for 2018!

Hello Pirouz,

thank you for the reply.

When I run the downloaded SYNTACTIC_V_2.7.exe the files have been extracted in a folder in C:\Program Files (x86)\SYNTACTIC from there I copied the file SYNTACTIC.EXE in the GH libraries folder. After, yes the computer Rhino and Gh have been restarted. 

When I open the sample file  SYNTACTIC_NewVersion_sample_2.7.3dm Rhino tells me it can be open only in read only mode and when I open the  SYNTAZTIC_NewVersion_PublicRelease_0.2.7.gh I see an alert telling the plug-in SpaceSyntaxDesign_GH is missing and when the file is opened all the Space Syntax components are (obviously) missing.

Hi Francesco, 

Thanks for your compliments. I suppose you have already restarted your computer, Rh & GH? Was the folder containing the GHA file zipped? then I would suggest to unzip it before copying. Could you please try loading the included example files?

I hope this helps but if the error persists please let me know.

Hello Pirouz,

thank you for your work.

I placed the file SYNTACTIC.GHA in the Grasshopper Components Folder but there is no SpaceSyntax tab when I open Grasshopper. The gha file is unblocked and Rhino was not running when I placed the file. 

Any known issue? Thank you.

Francesco
