It’s been awhile since I used Kangaroo and cannot seem to find the Reciprocal Structures component in Kangaroo2. I also opened an old script and it says that component is missing.
Thanks.

Shapefile geometry too small
@shoshana wrote:
Hi,
I am new to GH and am following a tutorial for importing a shapefile geometry and extruding the surfaces along the z axis with excel data: http://duspviz.mit.edu/tutorials/importing-gis-data-to-grasshopper/
Everything seemed to work OK, except that the shapefile geometry is coming in extremely tiny. The surfaces are also coming in distorted, but most likely it is because the curves are scaled so small.
I think it may have something to do with the CRS. The .shp CRS is epsg:4326. Does anyone know why the geometry of the shapefile may be so small?
Thank you!

Hello Everyone,
I would like to ask for small help about applying an uniform load on the upper ring / or support (boundary conditions on the bottom of the structure in Grasshopper using Karamba 3D.
The Structure is a lattice cylinder which will be very similar to this

Hello people!!
I’m trying to make the curve - rectangle - that will follow the sweep command but the fillet edge keeps giving me the following message: “naked edges can’t b filleted”I didn’t quite understand how to solve this program message, has anyone ever experienced this problem and could help me solve it?

Double curved surface form finding using strips

Good afternoon,
I am trying to do a double curved surface using joined strips like this picture:
I already have the curves (strip edges) on a curved mesh, and I would like to use Kangaroo 2 to prove that the strips would stand.
Can anyone help me with this problem?

Can't install ladybug and honeybee
@natalietai.m wrote:
Hi guys, I really need this so I really appreciate your help.
I’ve been trying to install ladybug and honeybee but i can’t seem to drag and drop the file components onto the canvas. I have GH_Cpython, ghpython2 and GhPython. Eventually I dragged and dropped the file components into the GH libraries folder and restarted by rhino but ladybug and honeybee tabs were still not on there.
Any ideas?
Much appreciated!

Generate/ Re-mesh from closed segments

Hi all,
I could make a mesh from closed same-length segments by using Delaunay Mesh/ K1: Remesh
However, what I try to achieve is a mesh like in the right image which is constructed from same-length segments as many as possible.

Any instruction to get this form would be appreciated.

Grasshopper Component Dictionary (Where can I find this component?)
@archjahzzy wrote:
Dear All,
I am following a Tutorial from Mosquito Plugin. They used a node that is not part of their package (I assume it’s from the OOTB Grasshopper components). I am specifically looking for this right now:
Do you have any idea what component it is?
Also, is there a site listing all the OOTB components & their explanations?
Thank so much!

How to offset this 3D curve with fixed start end points on axis?

You can see a circle that is non planar and subdivided into several segments. I would like to “scale” the circle but I need the start and end points of each segment onto specfic axis, that i draw with the black arrows. The green curves gives an example, what I am looking for.
Thanks a lot for your help and time!

tOpos (multiple solvers in one program)
@poulliebmann wrote:
Hey all,
Does anyone know if there is a way to have several tOpos Optimus engines (the model solver) in one GH file? Whenever I insert multiple Optimus engines I get the error “Solution Exception: Object reference not set to an instance of an object.”.
The reason I want several engines is to have the program run iterations that change the volume fraction until an acceptable Von Mises value is reached.
Any help would be greatly appreciated!
Best Regards,
Poul Liebmann

Animating with Python in Grasshopper
@Ryan_Whitby wrote:
I’m looking for a general method to animate loops with python in grasshopper. Attached is a basic example of what I mean. In this example I have 3 points chasing each other. I am animating by using and internal timer that increases the range of the for loop incrementally and continuously. The problem is this method is that each “frame” it has to run through the entire loop which gets longer and longer as time passes.
Would there be some method that could bypass running though the entire loop? For example would there be someway to overwrite the intial variable with an operation store that value and then update the compnenent again using the new values without creating an ever increasing range? Does this make sense?

Conflicting plugin files
@rcmcdougle wrote:
I just updated Human.gha to the most recent version and this started popping up. I appreciate that there appears to be a different folder for GH in Rhino version 5 & 6. I currently must run both versions of Rhino and I am developing GH docs for different clients targeted to those different versions of Rhino.
Is there a way to tell GH/Rhino5 to look in this folder and GH/Rhino6 to only look in that other folder?
TIA,
Robb

Grasshopper tree path with null item
@cshea wrote:
Hi
I lofted a series of curves to form surfaces - some of them were unsuccessful and the path in the tree data showed null.
when I unrolled these surfaces, the tree data with the unrolled surfaces no longer had the paths with the null items.
in the example, surface index 49 was an unsuccessful attempt and branch path 49 is missing.
How can I reinsert a branch with nothing or null or an empty branch at branch path 49 so it forms a placeholder path?
Thanks
