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:

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!!

If you are encountering a problem with rhino 6 versions don't worry
Follow these steps.
1. Download SYNTACTIC from

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

Hi Pirouz,

I am using Rhino 5 x64 version actually.

Comment by Pirouz Nourian on May 14, 2019 at 2:14am

Hi Shameem Ashraf, it could be that you are using it in Rhino 6; which might be incompatible with our last release. We are working on an update to resolve the issue. 

Hope this helps.
