Hi again,..
I´m still having the same troubles with the syntactic.gha !
I don´t know what to do, i copied it into components folder, checked the properties,, checked my rhino which is up to date, tried with various versions of grasshopper... the plug-in just doesn´t work/appear.

Enclosed i upload some screenshots which appear when opening the tutorial file... !
Is it anyhow possible that the problem could be windows8 !?

Hi Lois, Sounds confusing... did you extract the zip folder before copying the GHA file? Is your Rhino up to date? You can go to your rhino options and check whether it is or not. If the problem persists, please take a screen shot of the message which shows up when you try to open the tutorial file.

Hi Pirouz,

First, thanks for your response. I´ve been busy with other stuff in the meantime so i couldn´t come back to your message!

I installed the plug-in, copied the syntactic.gha into components folder & also checked if anythin is blocked. Additionally i set a all user properties to full access for the application/plug-in.
Still it doesn´t work & i have no glimpse why... sad story !

I opened the tut-file.gha & grasshopper reminded me that i don´t have the plug-in installed.

I´m running grasshopper version 0.9.0076 currently.
A fellow of mine is having the same troubles.

Looking forward to hear from you, Best Lois

Hi, we (I, Richard) are at 10th Space Syntax Symposium in London. Will have demos of new features on Tuesday (Richard) Thursday (me).

izaka: a quick answer to your questions. Just checked the files. 

In the first series: your graph might not be planar or otherwise the set of areas you desire make it impossible for disks of those sizes to fit together nicely. a simple definition of a planar graph is a graph that can be drawn on a piece of paper without its connections crossing each other. If you can do that on a paper for your case please post your drawing. Checking planarity using algorithms is not trivial and the algorithm for kissing-disk drawing is not guaranteed to work. You can lower attraction coefficient to see something but if it is impossible to put coins of those sizes touching each other the way you want (according to the graph) then the algorithm fails. This is not a bug.

In the second set of files: you have not shown any connections (lines) towards North, East, West and South. Therefore you cannot expect the algorithms to work. The graph needs to be pinned to a perimeter otherwise the Tutte algorithm cannot possibly work.

Hi all, sorry for late reactions. I'm having tough paper deadlines and many small matters to pursue these days. I'll just shortly respond and try to get back after June 1. Please help each other whenever you can!

Alois: I cannot imagine what is the problem... didn't you find a Space Syntax/Syntactic menu in your GH? Did you try opening the example files from the folder installed? You can double check the GHA to see in its properties if it is blocked. 

Oleksii Dorozhkin: Thanks for your compliments! Good point. We had made such a video with Sama but seem to have lost it!? I'll do my best to find it and put it on youtube. It will most probably be somewhat outdated though!

izaka: I will do my best to check your files but unfortunately cannot promise anything until June 1. If anybody can help I will be very grateful!

Hi i´ve problems installing the space syntax plug-in !
i downloaded the plug-in, installed it & copied the .gha into components folder...
also checked the properties of it & it should actually be fine ?!
anybody a few helpful suggestions / advices ?!
Best Alois

I´m runnig Rhino5 + latest Grasshopper version

Hi, great work here!

I could not find anywhere video tutorial for SS 2.7 but I definetly whatched something like this in february (with room orientations). Could you please help me with this link?

Food4rhino site has no SS/Syntactic page but I suppose it was exactly the place I find this plugin. Does anything happened?

Thanks for great work anyway.

Thanks for your response Pirouz. 3D spatial layout!!! wow...can't wait for that to be released. Good Luck!!!

Kind regards & Many thanks

Hi Agneesh, from what you've written I understand that you have tried to use a bubble (kissing-disk) drawing for a graph that includes NEWS vertices. I would only use the original/spatial vertices inside. I think I have added a solution for this in the new example file. 

Re anchor points, it would be indeed interesting to add more anchor points; but note that in any case they need to correspond to the sides of a convex polygon for the Tutte algorithm to work. Anyhow, I am currently working on a new algorithm for 3D spatial layout that would not require this approach at all; just a Brep as the spatial constraint.

Re arbitrary repulsion forces, I find the idea interesting but I won't be able to add such a feature in near future. I'll keep it in mind. Perhaps a whole new set of links as unwanted adjacencies would do. If you are curious, you can find some models that fellows had shared earlier on re-making the graph drawing algorithm using Kangaroo physics.
