Testing similarities does not retrieve the expected boolean count?

Testing similarity between two sets of decimal numbers (x and y coordinate of pt1 and pt2 attached). I do not get the expected count of boolean values (15,682). Could it be a decimal to binary conversion issue? Changing the threshold does not always help, especially with many more numbers. Any help would be greatly appreciated!…See More

Change tolerance for one component and not the whole file?

Hi Guys,Is there a way to change the Rhino tolerance specifically for one Grasshopper component? For example a "curve curve intersect" component could use a tolerance of 0.1mm when the overall Rhino tolerance is still 0.01mm.If that's not possible it might be good to add a "tolerance" input to all the intersect components?Many thanks,ArthurSee More

"Hi  Dedackelzucht, thanks a lot for the tip, works well :) One question though, isn't the modulo of n by the path_count always equal to the n value? What happens if you only use n? "

"Very helpful tools David! Is there a text/discussion on why David chose to introduce trees as opposed to describing it as "nested collections"? Are trees used in any other language?"

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

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.

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.
