Hi, I have been researching how to apply Tara Donovan pattern on different surface from this thread Create such a this pattern in grasshopper , but currently I have experienced the problem that the curves are crossing over after generated by kangaroo.

Issue with GetGroups component of MetaHopper

Hallo mr. Heumann,
thanks for your work.

I have a question about the GetGroups component of Metahopper.

It is a fundamental component of my scripts, but unfortunately I think it has a bad fault, because every time a new group is created, switch the value into the “nickname list”.


Having more GetGrups components in the same script, I have to go and fix them all manually.

I wanted to ask if there was a way to block the value, even if a new group is created.

Thanks in advance Andrew.

Shell Structure for Stability

Hi Karamba-users,

Currently I’m struggling with creating a shell to make my structure stable.

I don’t want to calculate the shell structure, but I only want to use this shell to bring the horizontal windforce to the columns on the structure on the side.

Does anyone know if this is possible?

Hello Guys

Please tell me how you can customize the display of the name of each node on top of the message

in the picture below yellow, all the nodes that are added from the menu already with such captions on top

Shortest Walk Branching on 3 sided brep

I am attempting to create a branching pattern on 3 sides of a brep rectangle with a few supporting points on the interior (columns) so the space can be occupied. The Script I have seems to be working but I do not have endpoints within the pattern. Here all the branches are continuous. I have been going through the forums have have been using this thread to start. I’d like it to look like this just on the box. It would also be useful if it worked on other surfaces as well and not just this box.

A little help with the taper would be appreciated as well. Cocoon is interesting but is very computationally heavy. I have been looking at pipe variables as well. Is there a better way to produce the branches? This file likes to lock up and has crashed a few times when I try to run cocoon.
Current GH file:

BRANCHING.gh (16.6 KB)

It doesn’t seem like the two point populations I have are acting as one single population which would be necessary to branch between them. I am primarly interested in creating the branches on the brep surface itself than on the interior but when I just use populate 3D there isn’t enough points near the perimeter.

Imagine looking up at a silhouetted tree canopy. That is what I am trying to create as a facade. Can anyone help get me moving again?

DIVA for Rhino/Grasshopper

I would like to do an daylight/thermal analysis for a initial architectural massing model. The shape is made up of a few different spaces creating a slightly angular polygon. As DIVA needs to use a grid I have broken up the space into several rectangular areas to use as my grid spaces for DIVA. I want to run the simulation and see the results on all grids at once. Right now when I run it only one daylight grid will show. What can I do to get all simulations to be visible at once? (It is not a matter of turning the preview on, I have tried this!)
Also, I am running this script through Grasshopper but my geometry is created in Rhino (if that helps)
Thank you so much (in advance)

Checking for Circles within Circles, c#

Hello,

Beginning grasshopper question here, couldn’t find the answer through googling, etc…

I’d like to randomly populate a plane with non-overlapping circles of random diameter, using the c# component on the latest Mac release (not WIP). I can successfully check for intersection using the attached, but this still permits circles within circles, as seen in the image. If someone were able to point me to the easiest c# way to get a bool value indicating whether one circle is within another (with the assumption that they are co-planar), I’d be most appreciative and grateful!

Many thanks!, Michael

Hi,
I calculated multiple ray intersection on several surfaces.
Now i want to identify the surfaces/faces where those intersections happened and cull the others that don’t intersect.
For that purpose I’m trying to find the equivalent of rs.isPointOnSurface in Rhinocommon … with no success quite several hours,
I’ll appreciate any help to find this command or other options to achieve the goal.
Thanks,

Treehelpers with weird runtime error

When doing the quite normal

output = ghpythonlib.treehelpers.list_to_tree( nestedList )

I get the weird runtime error:

Runtime error (MissingMemberException): ‘type’ object has no attribute ‘__index__’
Traceback:
line 32, in list_to_tree, […]

I’m not really sure why this comes up. Maybe @DavidRutten knows something?
Or somebody else ever had this error?

Using output = nestedList does “work” (you’ll get “IronPython.Runtime.List” of course).
output = nestedList[0] also works fine, you get what you’d expect.

Contour along curve

Hello,
I’m trying to use a Contour command where the direction would be specified by the normal of the curve.


Here magenta contours are representing what I want to achieve. I managed to did that all the way around but essencially I would like to be able to modify the number/distance of those ribs.

I defined all of the normals of the curve tho I don’t know how to apply it to the Contour command (simply connecting the results doesn’t do the trick).

Hello,
I am trying to create a mesh for topological optimization and am running into trouble with my domain (mesh) not working.
The shape of the mesh that I’m trying to create is shown below:

This shape has different number sliders that determine the overall dimensions. The mesh that I’m getting isn’t working, I think because the meshes don’t really connect.

Maybe it would help If I could just create unique surfaces that form a single connected surface?
Any help would be greatly appreciated.
