Mapping a hexagonal grid on a surface + Karamba for beam sizes

"Arthur, I'm working on a project involving hexagonal geometry in karamba, and saw this posting yesterday.  I rebuilt the script based on your attached image, however when I set a surface to the definition, cplanes explode all over the…"

David Rutten replied to Arthur Mamou-Mani's discussion Is there a Grasshopper to Rhino Toolbar convertor?
"No it's really difficult to use Grasshopper files while circumventing the Grasshopper window. I don't think there's any plug-in that automates the loading, assigning, solving, harvesting, and baking of specific GH files."

Is there a Grasshopper to Rhino Toolbar convertor?

Hi Guys,Crazy question / moonshot - Is there a Grasshopper-to-Stand-Alone-Rhino-Toolbar Converter out there? A client has asked for a custom toolbar but it would be much faster for us to do it in Grasshopper than script so any guidance would help.Many thanks,ArthurSee More

"Yup, when this discussion started that component didn't exist yet, but these days the best way to remove the last item is to use Cull Index with index = -1."

Save the Rhinos

Hi guys,

This post has nothing to do with the software but with the animal !
The Eastern Black Rhino is getting dangerously close to extinction, with only around 500 left in the wild.

Please help support the conservation effort by donating to this website:

Many thanks,

Parametric Biodome in Chester

Hi everyone,

Here is the project i have been working on for the past 10 months at Proctor and Matthews Architects, we have just submitted the planning application:

Once completed it will be the largest freeform gridshell in the world.

Most of the roof structure has been worked out using Grasshopper.

Thanks a lot to everyone who helped on this… Continue

Sorry for being late, Arthur.

I had not noticed your request ...

Thanks for your friendship !

Hi Arthur,


I have manage to adapt this definition that Daniel Piker worked on(circle packing), o an image-field that defines the radii of the circles, but my main target is to optimize the radii for a better arrangement and population within the image-field allowing the radii to change and adapt during the simulation... some one posted in you tube a great video where they show this plus other interesting packing logic's....

here is the link:

any suggestions about to achieve similar results as image base/fighting for space....?

Hi again,

I have solved the problem this morning with 'surfacesplit' (since I was dealing with splines creating surfaces, and those needed trimming there where they were overlapping) + some 'list' and 'tree' paths that where not correctly setup.

Hi Arthur,

hope thiongs are well. - Not yet, I have done some trials with the 'region' and/or some of the 'surface' and 'intersect' tab utilities but with no luck. - The real issue is to delete overlapping surfaces...

In any case, thanx and let you know if I get a solution.

hi Arthur, nice to see you here, best. Affonso Orciuoli, if you planning to come to Barcelona, write me.

Arthur, thank you for your comment, in fact I used to have but now  I doesn't have it now and I don't know  who seizes it now..

Thanks Mani, well, the method is very simple: we first need to create a rectangle based in a loft operation of some curves with control points, subdividing the surface, then we need a  surfacebox operation later the boxmorph with some geometry. We could  move the control points on one vector, and presto!,one organic flow.
