dy stuck.
The basic concept is to create a 3D boundary(a box),
by generating random differnt values(length) and vectors(xyz),
such as (0,0,2), (-3,0,0), (0,1,0), then connect these points in order,
so there will be a snake(polyline) running in the boundary and
keeps growing longer through looping.
However, I can't quite understand how to use hoopsnake to achieve such action.I tried many times but all of them doesn't work.
About the 2 gh files below,
Gourmet Snake 3D.gh is before I use Hoopsnake,I tried to run it without boundary.
Test snake.gh is that I tried to generate a random number for every loop, then save them all and sum them up every loop, so I can check if the result is out of boundary,
if true, then I can mutiply -1 to let it decrease till it's in the boundary.But I can't achieve it through Hoopsnake.
Sorry for the poor english expression,if you understand my problem,any suggestion will be appreciated.

metrically along a given surface or curve, creating sort of a mesh or swarm. Each swarm element should attach to previous and next one in a specific fashion.
Here's what I've come up with so far:
The red lines are mountain folds. The folds shouldn't be static, but vary according to the position that they need to be in, to make the swarm structure possible. The gray hatches are contact areas, where the the swarm elements are attached to each other (but don't need to be in the 3D modell):
The quick sketch above shows how the different swarm elements should attach to each other. Furthermore, they should be able to vary in size. Is this even possible?
How do I start?
Can anybody please point me in the right direction? Thanks. :)

ude a solid with sharp edges, and then I try to fillet the edges.
The problem is that the process is very time consuming because there's a lot of guess work as to what radius you can apply. Also the result isn't very good.
I'm looking for a fast way to do this, and I was wondering if there isn't a simpler and faster way to do this with Grasshopper.
Here below are 2 images to illustrate and I attach a file if anyone would be kind enough to give it a try with Grasshopper.
Thanks in advance for your advice
Seb
1. This is what I have when I open the Illustrator file:
2. This is what I'm trying to get, even thought the result isn't great, and it takes way too long to do with Rhino's fillet edge function
Thank you,

ons, variations, and "cross-breeds" of consumer electronics product designs, for example, telephones:
Or for example, to generate and populate control panels with parametric variations of knobs, dials, etc.:
I've been reading up a bit on procedural/generative modelling, shape grammars, etc. But the first basic problem I've run into, is that all the devices I'm interested in generating have filleted edges, and I've read that Grasshopper can't do that, because the FilletEdge command is not exposed in the SDK. I did read however that in Rhino 6, fillets will have history - so I wonder if that opens it up to Grasshopper at some point in the (hopefully not too far) future? Or is there some other approach that would help in generating these kind of forms in Grasshopper?
I guess most people doing this kind of generative modelling for CG/games would use Houdini or 3DS Max, but I want to be able to actually build some of these things with 3D printing/CNC, so I think I would be better off in the NURBS/solids world? I also looked at Solidworks/Inventor, which do very well with parametric fillets, but it seems like it would be difficult to get them to do the kind of generative stuff that Grasshopper can do, fooling around with Excel spreadsheets and formulas. Unless I missed some kind of Grasshopper-like plugin or scripting system for them?
Anyway, comments appreciated. I can imagine Grasshopper being quite useful for industrial design concept exploration, surprised that I haven't seen more of it...

ng and algorithmic design for furniture production. Ideally I would like to be able to import a network of curves into this definition to automate the node creation process. Unfortunately as it stand it will only work for one of them.
My question is, how can I present a list of the connection points & vectors from a network of curves for this to work?
Below you can find the definition along with a few pictures of the concept and development. The white parts were modeled in Solidworks and printed on my Ultimaker 2.
If you're interested in following this project I'll be posting regular updates on my twitter: @pencil_stroke
Thanks in advance,

ning the simulation looks great(see figure 1). However, I find some question(see figure 2), the red wire frame on the right should be symmetry like the physical lamp, but it has a extend distance now.
I should like to keep the wire frame structure with same length after simulation.
maybe I miss some setting in Kangaroo, can any one fix it? thanks in advance.
I put this ghx file under the attach.

ing so I am trying to code it.
I am trying to extract the points within the blocks, I have successfully done so, the output is rhino.docobject.pointobject but as soon as I try to use that grasshopper recognizes it as a goo object.
I have tried converting it inside the script but then the vb throws a conversion error
it can convert a rhinoobject into a 3d point.
This is the code:
Private Sub RunScript(ByVal T As Boolean, ByRef A As Object)
If t Then
Dim objlist As New List(Of Rhino.DocObjects.RhinoObject)
For Each rhobj As Rhino.DocObjects.RhinoObject In doc.Objects
' this selects only the blocks
If rhObj.ObjectType = ObjectType.InstanceReference Then
' this gets the objects in the block
Dim obarr() As Rhino.DocObjects.RhinoObject = rhobj.GetSubObjects
'here I put them in a list
For Each blockobj As Rhino.DocObjects.RhinoObject In obarr
objlist.add(blockobj) Next
End If
Next
a = objlist
End If
I'm pretty stuck, any ideas would be much appreciated.
Thanks to everyone, and long live the grasshopper community.…
n elements in grasshopper.
So, I found myself rather blocked, not being able to do certain operations which I need:
1. I can't close the tubes, leaving the center circle open, when I try to input the cap holes, it takes all the tree and it closes, and I am still confused about how to edit trees and items. It would be rectangular shaped holes, rather small (it is intended for bicycle wheels, thus rather thin and long). I wish to be able to change the amount of these holes, since I am not certain yet.
2.In the same time, I have no idea how I would create a slope joining the 2 vertical boards ( floors).
Here is a small drawing explaining what I am looking to draw
In the same time, is there a way to create a slope, joining the same floors, but build on a different principle.
A slope revolving around the long vertical tubes ( trees). As in the image below
Thank you beforehand for your help, if halfway, you see the there is a faster way, or that would be more of a grasshopper way, of creating or changing an object, please do tell me, it would help me understand GH better.
I wouldn't have asked, if I wasn't this tight in terms of time, and if I had the slighest idea on how to do it. So pls help, and thank you.

ittle weave-ready ribbons appeared:
Though the Mesh+ plug-in has a few "weave" components, they only make local loops between adjacent mesh faces.
So I did the bookeeping required to create little construction ellipses and little stubby start and end lines offset in and out from each mesh edge to allow a curve blend and then rail sweep of locally rescaled ellipses along those curves, with lots of control.
There are occasional tube self overlaps due to kinks that would require fixing in other software to 3D print the output.
Interestingly, the result is sometimes a single knot curve, more often a mere handful.
