Hi  Jonathan Wiederin,

The WIP version was developed for the latest GH and Rhino5. 

Any installation challenge?

Comment by Jonathan Wiederin on December 11, 2017 at 7:09am

Hey Pirouz

Could yo please tell which version of Grasshopper and Rhino you are using?

Hi Michael, We have switched to Accord.NET for the new version (to be released hopefully before Christmas). I know it can be difficult to find Math.NET without going through installations. For the time being, I don't know if the licence allows me to share the dll publicly here. Could you please send me an email to

Best regards,

I am trying to install this as the GSI / FSI functions look interesting.

I am stuck on the stuff as they seem only to provide the libraries in some Microsoft Visual Studio compressed format from which I cannot extract the required dlls. Am I missing something?

Thank You for the advice. I will try qgis.

I`m using the WIP Version from your website.

If your new version of Cheetah is ready i would be glad to test it.

Comment by Pirouz Nourian on November 30, 2017 at 9:23am

BTW,  Jonathan Wiederin, are you using the WIP version from my website or the last GHA version?

Comment by Pirouz Nourian on November 30, 2017 at 9:20am

Hi Jonothan, thanks for your compliments! I have a completely new process for cleaning networks and I have also rewritten half of the plugin. theoretically I could release a new version in a few days but I cannot promise a date actually because of our very heavy education workload at this moment. I know that it is possible to do network cleansing with QGIS. If you can code in Python or C# I can also help you snap all line end points to a grid, so that they really connect to one another. However, this business of cleaning networks is quite tricky in general. If it is only one study, then a visual inspection also helps (zoom in/zoom-out, clean/replace the problematic parts). I hope this helps a little for now.

Hi Pirouz 

Thank you for the great Plugin.

Are you still working on Cheetah?

I get the same error when using it.

"Solution exception: Value was either too large or too small for an int32".

Can you recommend some Plugins or tool to clean up streetnetworks to avoid this error? 

I had some success with the Plugin Vipers. But still get the same error.


Comment by Pirouz Nourian on March 27, 2017 at 1:52am

Hi Tom, I can see that the tolerance for error (tol) is quite small compared to the scale of your network segments, please try raising the tolerance and check the "out" content of the L2L graph component.
