algorithmic modeling for Rhino


Space Syntax

Space Syntax is a theory of architecture and built environment that seeks to explain the effect of spatial configurations on behavioral patterns of people. SYNTACTIC tools bring Space Syntax theory into parametric design workflows. More information on syntactic design methodology:

My PhD dissertation (see chapters 3 & 4)

Designing with Space Syntax

The plugin is available for download here:

This plugin is completely compatible with SpiderWeb for Grasshopper and we hereby thank Richard Schaffranek for all we have learned from this extremely useful plugin


UPDATE: Genesis Lab [webpage][website] is to modernize, open-source, and develop the toolkit starting in December 2021. Stay tuned for updates through my YouTube Channel and ResearchGate

Hi, All components are ready. We are just wrapping all our VB codes into a GHA.

Hello Leen, apologies for responding so late; I have been overloaded with education these months. The error sounds to be related to a mismatch between the number of attributes provided (tags, colours, areas, etc). If it is a bug caused by something else, we can perhaps replace the module with a custom-made python module. Please let me know if there is an update on this issue.

Hello guys

Im having a problem that after almost the 12th space is added the diskograph component that produces the bubble diagram stops working! always after this number of spaces it starts giving the error "object reference not set to an instance of an object" 

It only works if I turn the boolean toggle to false for the forcedirecteddrawing component but then again the bubbles are not adjacent anymore! any comment please?

Thank you :)

Dear group members, I hope all is going well with you.

Our plan for the future is to share all algorithms open source in Python. You can find one of the most wanted ones in one of our GitHub repos (graph relaxation in 3D and more). There is much more already in our GitHub repos and more to be added. For getting an idea of our future direction check this lecture out. For getting a better understanding of graphs and graph theory watch this lecture and this lecture on a gamified spatial configuration process. Stay tuned for more and do not hesitate to post Python questions in the meantime.

ps. If you are having installation problems, please check the remedy suggested below:

If you are encountering a problem with rhino 6 versions don't worry
Follow these steps.
1. Download SYNTACTIC from
2. Install it and go to the installation folder, Drag & drop SYNTACTIC(green one) over your grasshopper canvas.
3. Close your rhino and reopen it. 
4. Type GrasshopperDeveloperSettings
5. Tick the Memory load *.GHA assemblies using COFF byte arrays option
6. Run grasshopper and enjoy plugin

Dear Pirouz Nourian

Thank you for your kind reply. I really appreciate your syntactic. The ‘triangulate mesh in all ways’ component doesn’t work. I followed the procedure of your PD paper and watched your video ‘SSS9 Parallel Session 1 Pirouz Nourian’ on YouTube over and over again. But I fail to find the solution. Please help me.

I found that there are many people have the same problem with me in space syntax group. I know you have heavy education load. It is more better that you record a video of your own operation to guide the steps in detail in ‘syntactic exploration’ when you have some time.

Best wishes.

Hello 王海涛, 

The version on Food4Rhino is unfortunately incomplete. I shouldn't have put it there perhaps. Please use the old version from my website and refer to the instructions of Iman Sheikhansari for getting it to work. 

I hope this helps.

Hi YUAN SHENG LIN , thanks for your compliments. For a detailed explanation on the force directed graph drawing algorithm please see page 100 of my dissertation. 'Str_att' is the strength of attraction and 'Stre-rep' is the strength of repulsion. For very complex bubble charts or situations that do not result in a convergent diagram you can first try lowering the repulsion and then the attraction to get a near optimal layout. 

I hope this helps.

Hello, thank you very much for developing such a useful plugin!
I have some questions about the parameters in the process of using this plug-in. In the "force directed drawing" component, is there a more detailed description of the two parameters "St_Atr" and "St_Rep" and the impact of the parameters? Thank you very much!!
