Move points on a curve
@adcarldg wrote:
Hi everyone,
Does anyone knows if it is possible to move some points on a curve.
I have some ellipse that i have rescaled, moved in z and divided to obtain some points and link them thanks to an interpolate curve.
the thing is i would want the interpolate curve draw a spiral on my shape and not draw a “straight” line
I have tried to rotate or use a serie component but of course it moves the point everywhere and not on the curve i have also tried to use the evaluate curve component but i don t know well how to use it.
Here is what i aim:

Honeybee transferring field-points in light direction
@jan.d.keller wrote:
Hey there!
I have a question concerning honeybee. I hope someone has an idea or can give me a hint. At the moment I’m working on the idea for a parametric facade while using honeybee data to provide a field on which the facade will be generated (with Wasp). I’m able to get points with values inside a room. The problem is I would need those points and values at the point of entrance into the room (windows) to be able to run Wasp to generate the facade. Is it possible to get certain values on the way between the light source and when it hits the ground inside the room?
I hope the attached picture explains it a little bit better. The Grasshopper file is also attached.honeybee_daylight.gh (507.2 KB)

Color of selected groups

Hi,
Do any of you know if it’s possible to edit the default color of selected groups on the canvas. I haven’t been able to find it in the SDK (I would expect it under GH_skin members)

Complex boolean

hi all,
this is a topic that always hurts…
I am trying to make a complex boolean operation in 2d as you see in the image. I have tried many ways and I haven’t had any success. (the only way was with consecutive solid union and Merge faces but it becomes extreeeemely slow)
The purpose is to produce just a 2d design to be used for cnc.

Honeybee GH - How to extract Lux?
@jcmv_design wrote:
Honeybee Basic.gh (497.5 KB)Hi Guys,
I’m currently trying to show Lux levels using honeybee with a simple daylight setup.
My problem is that the toolbar / legend that shows illuminance levels doesn’t appear when I run the simulation.Legend can be seen in the video above.
Has anyone run into similar problems? Or does anyone know what might be causing this i.e. falsecolor, missing honeybee component etc.
Any help would be greatly appreciated,
Thank you

Lunchox paneling on multiple surfaces
@niander wrote:
Hi everyone!
I’m new to using grasshopper and have been going some tutorials for the lunchbox plugin.
I’m having difficulty placing a paneling grid onto multiple surfaces. Whenever I create a group of surfaces, the panels never match. Some of them are oriented differently, depending on the surface. I can try and get them to match using a slider, but they are never a perfect match.
Is there any way of making sure that all of the surfaces have matching UV panel settings?
Thanks

Remove Spikes of a Mesh
@Benjamin4 wrote:
Hi everyone,
I am looking for a way to remove spikes of a mesh which do not fit in at all to the total mesh geometry. I created an example here:SphereSpike.3dm (968.6 KB)Is there any possibility in Grasshopper/Pythonscripting to remove such a spike?
Thanks a lot!

Rectangular Point Grid - removed?
@Emma wrote:
Quite new to Grasshopper, so now having a look into components. Has the Rectangular Point Grid been removed from the software? I see it mentioned in a learning material, but the only thing similar to it that I can create in Grasshopper by using only one component is the RecGrid - and that generates a grid of cells instead.
Curious if that exists or otherwise - what is your best/fastest way to create one?

Bezier Curve and Isotrim (Subsurface is invalid because the trimming V-domain is singular)
@andrea.basso.13 wrote:
Hi,
I am trying to trim a surface in both direction in uneven spaces, using a bezier curve. But since I am planning to use Galapagos to optimize the geometry, I found a script that simulates that geometry by using number slider instead of a graph mapper. When I adapt the geometry to the y direction everything seems to work fine, but when trying to divide the surfaces in the x direction in the isotrim component i have the error:
- Subsurface is invalid because the trimming V-domain is singular.
I have no idea what might be the problem and I already have a reparametrized surface.
Can anyone help me?
Thanks in advance

Mesh Colours problem
@Francesco_De_Luca wrote:
Hello,
recently Grasshopper Mesh Colours component is not working.
Meshes get totally black.
Any known issue? (maybe in the latest GH releases - Rhino 6 SR6).
When using Construct Mesh then meshes get colored (though not nicely as with Mesh Colours).
Also with other components that output colored meshes the result is total black.As an example I show three images, the original mesh, the mesh colored with Mesh Colours (totally black) and the mesh colored with Construct Mesh.
Thank you in advance.

Get off the Bike - Lazy Zombie Sliders Desperately Needed!
@RIL wrote:
OK so, so you have a huge GH definition downstreams your Number Slider and you don’t dare touching the Slider.
Because the Slider fires on every “resolution tick” while dragging.
Therefore, if @DavidRutten would consider taking a breake from his MT Bike and join the forces again, I suggest adding a state or mode to the Number Slider activated with RMB which opens the Component menu presenting an option reading “Lazy Output”, meaning that the Slider now fires its output value only after the LM button is released, and not while dragging.
Made available for GH1/Rhino6.
In short, I’m in desperate need of realtime performance for moving reference planes and points for further complex calculations of geometry (example pictured below).
Slider De Luxe available tomorrow? Cough, cough, cough.

Diagonal on a triangular grid (lunchbox)
@camillarozario wrote:
hello guys, sorry this might be a very simple question but still learning the basics for GH and having some dumb issues.
So I used a lunchbox plugin to grate a triangular grid… I wanted to get the diagonals and select one of them. As far as I was able to accomplish i could get all the diagonals of the grid with the mesh edges component (also from lunchbox). but when I try to select one of the diagonals with the list item I get only a piece of the diagonal. Tried to join the curves but still get only a part of the diagonal. I want to select the entire line of only one diagonal… is that possible?

Component Icons in toolbar not displaying?
@ekihm wrote:
Grasshopper suddenly decided to not show the icons of the component tabs anymore. I can’t find if it was a random hotkey that did it or a setting switched, nothing seems to reset or bring back the icons. I’ve tried toggling the “Show obscure components”, toggling the component toolbar tabs, and toggling “Show tab icons” but nothing brings back the icons.
Is this a Mac bug? I can’t find any solutions or even anyone else having this problem. Any help would be appreciated!

Selecting "visible" points and not ones that are in shadow of geometry
@chris.pm wrote:
Hello
I have a geometry and a Point P
I have populated the Geometry with multiply points MI would like to conect point P with all points M that are “vissible” to P
The best way i know to discribe this is a refrence:
In maya there is a way to select vertesies with “camera based selection” meaning you can only select vertesies seen by camera (If you have a sphere and do rectangular selection and CBS is on you only select vertesies on the side you can see)does anybody know a way to do this in grasshopper
i thought about connecting all M’s with P and then intersect all MP’s with the sphere and if there is a intersection i tried to cull them. but i am very new to GH and i didn’t manage
I would appriciate any help
thanks!
