algorithmic modeling for Rhino



SpiderWeb is a .NET library providing functionality for preforming calculations on graphs. The library is created with a special focuse on the integration of graphs and graph related theroies (e.g. SpaceSyntax) in parametric design envoirnments. Therefore special Versions are avalible for:

DesignScript (planned)

Dear Richard, Dear group,

I am working on a masterplan using a space syntax approach to investigate a performed distribution.

I would like to connect the points (rapresented as function program) with specific rules, with one vertex liked or not to other..basically i have a matrix and excel spreadsheet for that.

The space syntax plug-in needs a manual link among verteces that for a great number of points or functions, the mistake is behind the door!

i love to do some more flexible definition, where any time the matrix can change and describe different environment.

I tried with a " Graph represented as list of vertices" component but doesnt seem my case.

Any suggestion is welcomed.

thanks in advance

Hallo Frano,

Have updated the specific file. Do know, for two other samples the link goes to no where...

Comment by Frano Bazalo on October 27, 2014 at 13:37

Thanks Richard,

That would be great thank you.

FYI, many of the other links don't have a download attached.

Looking forward to the examples.



Comment by Richard Schaffranek on October 27, 2014 at 13:34

A okay, this explains it. Have forgotten to update the example to the current version of SpiderWeb. So the example will not work with the new release. Sorry.

Will look into it by the end of the week

Thanks for your quick response Richard,

The new version of SpiderWeb seems to be installed properly.

The example is from here.

Does that still load properly for you?



Comment by Richard Schaffranek on October 27, 2014 at 13:25

Hallo Frano,

Hmm hard to tell.

Do the SpiderWeb Icons appear under the "Extra"-Ribbon?
If not did you follow the installation Instructions:

Where did you find the The current version of SpiderWeb comes without any examples. Some examples can be found under the link above.

There is also an old Version of SpiderWeb with more examples which will only work with the old Version.

Best Richard

Hi Richard,

I am having trouble loading many of the example files. 

For example the "graph definition"


Any suggestions or further examples would be extremely helpful.

Thanks mate, that solved the issue. thank you.

I am doing my final project for master of architecture at the University of Adelaide. I am analysing a town with space syntax theory to come up with a best solution for a city centre master plan. Spiderweb will help me. Thank you to share this interesting add-on

Hallo Azad,

Did you copy the dll files as well?
An instruction on how to install and further samples can be found here:
