Hi Pirouz.

Your Syntactic is very exciting!

I'm having a trouble with a component 'Triangulate Mesh In All Ways'.

The error message is:  '1. Solution exception: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

The goal of my project is to allocate room boxes at points generated by space syntax without overlapping each box.  The boxes don't need to kiss each other because I'll connect them with corridors using edges generated by SYNTACTIC (Does a component 'Graph Edges' work for this?).

I'm also looking forward to updates which enable point generation in 3D volume!

Hello Pirouz

Thank you so much for this tool I believe its going to be of great help for me in my research.

However, I have so problems in starting it, the version on this website doesn't seem to work on my Rhino 6. Even after trying to unblock it and pasting it to the components folder.

I downloaded the one on food4rhino, it worked, but its missing many components

any suggestions please?

Thank you so much

hello , Mr Nourian
According to the upgrade of your new plug.
It 's possible to renew a teaching video to get acquainted with the functions version for us.
Thank you.

Hello Maryam, we are working on an update for Rhino 6, ensuring compatibility with the new library. I cannot promise a new video anytime soon, but will be happy to answer short questions here. 

Hello Leen Hiasat, 

thanks for your compliments. The error you are mentioning might be because the NEWS graph you are putting in is not 3-connected (has more than 3 vertices and remains connected after removing any 3 vertices), or because you are trying to find a triangulation that does not exist (referring to a high index). 

The package released on Food4Rhino is indeed incomplete. We are working on it. Cannot promise an exact date but doing our best to release before the end of the year. 

Hellow Yuki Wada , 

I checked your file and noticed there were quite a few errors caused by empty entries in your lists (I guess that is because I am opening your file in GH for Rhino 6 and that you have made it in GH for Rhino 5). Apart from that, I see that your graph is not 3-connected (has more than 3 vertices and remains connected after removing any 3 vertices). That is an issue. I saw at least one (Yodo r) node that is only connected to north and west. That is a breach of 3-connectivity. In your Tutte Diagram I also see that there are a few nodes connected to nowhere. That is also a serious problem with the graph drawings ahead. 

Hello Nourian,

I'm having a problem with the tool "DiskoGraph" 

It sometimes gives me this error

"Solution exception: object reference not set to an instance of an object" and refuses to produce the graph.

What might be the problem please?

Thank you

Hello, Pirouz

How can I bake the graphs? I don't know if this question has already been made. 

Thank you for your time and effort

I found a little script that my help me in baking the graphs from the component "GraphsfromNodesAndLinks". This is already great and very helpful. 

Is there a way to bake the other output graphs? 

Thank you

Your research is very helpful

I want how to download space syntax inside rhino

Hi shimaa elsayed, the last working version (which might only work on Rhino 5) is available on my website: https://sites.google.com/site/pirouznourian/syntactic-design?authus... (download button at the bottom of the page). 

At this moment we are working on a much delayed new release but due to my bust academic schedule I cannot promise a release date. I might gradually post here some components as user objects.

Pirouz. Hello. 

Just wondering if there is a way to edit graph attributes like text size, colour, etc. 

I'm using the LOL component, but I can't find a concrete way to do it. 

Thnank you for your answer.

Hi! Sorry for the noob question, but I have installed the SYNTACTIC_V_2.7.exe downloaded from your website. Opened up grasshopper, found no tabs or tools, I'm missing something big, what am I missing here though?

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.

Hi Pirouz,

I am using Rhino 5 x64 version actually.

Hi
If you are encountering a problem with rhino 6 versions don't worry
Follow these steps.
1. Download SYNTACTIC from https://sites.google.com/site/pirouznourian/syntactic-design
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

Hi Iman Sheikhansari, 

Many thanks for sharing your solution!

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!!

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 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. 

Pirouz 

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.

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:

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 :) 

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, not all tools are available

How could i solve this issue

Hello gaston, you seem to have downloaded an incomplete new version from Food4Rhino. You can get the last complete version from here:

Stay tuned for more updates on Genesis Lab

I hope this helps!

Hi there, here is a new book chapter about going beyond analyses towards syntactic evaluations, containing some tutorials: https://www.researchgate.net/publication/354683441_Reuse_On_Evaluat...

Hello!I am using  Rhino7 and the .exe file I have ran does not appear in my GH canvas. Is there another location I can download a normal .gh component file? 

If the plugin does not appear in your canvas, try the following:

Hi Guys! I would like to use the idea of adjacency, closeness, betweenness of areas in order to decide on some dimensional parameters of my design. So, potentially I would feed the average shortest paths of each design topology as fitness measure into a genetic algorithm, and maybe Biomorpher. So let's say I subdivide the surfaces which occur below as iterations in Biomorpher and create a graph representation as routes and nodes. Do you know any heuristic which I can calculate the average shortest paths in such way? cheers!

Hi.... I am using  Rhino7.14.22010.17001 and the .exe file I have run does not appear in my GH canvas. Is there another location I can download a normal .gh component file? the one I downloaded from food4rhino is incomplete.

also, I did the way Samane explained but it doesn't work.

Hi Eman Baadullah,

While running the exe installer file you need to specify a location in which the gha component will be placed. Please run it again and specify a location that you can recognise. Then you can follow the instructions of Sama to ensure that the plugin appears in your GH canvas. I hope this resolves the issue. The download link is here: https://genesis-lab.dev/products/syntactic/

Hi  asyimut, 

Interesting question! I would try to build a face-to-face adjacency graph of the meshes in question (e.g. using Ivy or Python) then you can use GH CPython to access NetworkX and compute all shortest paths (or centrality indicators) and do the rest in Python or GH. If you start the Python codes I can help you by giving hints on how to finish them. 

Dear Pirouz, 

Thank you for the great suggestions. 

1. Can I create a 3D graph representation of the topologies? Can you quickly see the figure1 in the attached paper? 

2. Then, NetworkX would recognise and compute the SP s in the 3D graph? 

3. In the meantime, I made a very heavy model in which I can calculate a limited amount of shortest paths. See the attached image. 

This is a beehive design. The combs which are inhabitable on both sides are radially distributed around a central core. There is a corridor around the inner core, as well as a peripheral gallery. Bees can also move above and below the combs. So I need the 3D dimensions in my model, or my mathematical imagination is not capable of thinking this planarly? I used the library from this link https://github.com/danilnagy/gd_tools but my model is very heavy. I made a triangulated mesh in order to define all the paths that the bees can take and defined random 20 points as start and end points to find the SPs. I guess with your system this would be faster. This image represents how I would like to think of the nest spaces and connectivity but in the honeybee nest case- which is a designed one not a natural one-

Hi Asya, sure, happy to help, I find the Termite nests very inspiring; thanks for sharing the picture! Re your questions:

1. The notion of a 3D graph is somewhat confusing because the graph itself is not a 3D space but yes, sure, if the vertices are "embedded" (mathematical term for 'drawn'/placed) in a 3D space you can colloquially call it a discrete model of the 3D space... Bottom line is that you need to produce the topology of the graph as a set of edges connecting those vertices. Since you have the models as meshes, you kind of implicitly have the graph data in the mesh as face to face adjacency graphs. If you are familiar with Python I can help you write that. Or I might even find it as I have written it before and share it. In the meantime, have a look at Ivy, it has a tool that can produce such graphs (as far as I remember).

2. once you have your graph data as a set of edges, practically a set of tuples of two integeres, referring to the vertex indices, then you can initiate an NX graph and then you are all set for computing geodesic distances

3. I suspect that NX would be/could be faster in running some analyses but I must say I did not quite fully understand what is the goal/process. If you have a publication or a proposal or a description of the process please feel free to send me through email p.nourian at tudelft.nl. I would appreciate it if you could summarise the idea in a workflow diagram (even if drawn by hand)

2. 

Hi.. Where can I find more videos and tutorials about syntax?

Is there any way to convert the bubble diagram to a floor plan and control the shape of the rooms or areas?

Hi I'm a student from Thailand I want to download this but I can't download 
it because my Gmail doesn't have access. And I have asked for permission many times. 
please help me

thank you.

Hi  Eman Baadullah, good question! The answer is rather long; you can have a look at our new open-source approach in the course Spatial Computing : we are using a Multi Agent System to grow the parts of the building in 3D based on voxels. We also have a new open source process in Python for forming bubble diagrams in 3D that matches this process in VectoRelax (Graph Relaxation). I hope this helps. 

Hello everyone!

I just have a question on NodeLinkGraph component. Just wondering if anyone knows how to reduce the size of the text of the points? I worked fine on the first diagram, but now it's too big to even be legible. 

I need it quite urgently.

Thanks a lot!

Cheers,

Kim

Hello Kim, this component guesses an average size for the presentation of the labels; I can see that the size is too big so the smart procedure is over-engineered. Anyhow, you can turn off the preview of this component and use a controllable tex3D component to draw labels with an arbitrary size, but for doing that you need to create the labels, e.g. by using a Series component (provide the number of nodes by using a List Length component to the Series).
