Hi all,
Please help!
I don’t know how to make it work but here’s the idea:
I have 3 lists that has different list lengths and values and what I wanted to achieve is to specifically select the name of a list through a value list and it will output the assigned list according to its list name.
Any solutions are welcome!
Thanks!

Hi, Is there anyway in GH 0.9 to search based on explanation for a component. This will be helpful because sometimes you do not know the name of the component you are after. however, you can write few words to explain it. Any idea? Thanks

Hello, does anybody know what method is used in Rhino.Geometry.Matrix.Invert and in BackSolve? I’m guessing it’s a conjugate gradient method but am not sure.
Thank you.

It makes no sense to me why revolution would not accept vectors as axis of the revolution. Is this bug or it’s just being overlooked?

Hi there, recently I was learning how to use KangarooSolver.dll, I try using the examples(Dan Piker) on github but they all seem to give the same error, Error : Unable to cast “x GoalObject” to IGoal. Wearly the examples where the goal is created inside the script work perfectly but the examples where the goals are created using the kangaroo Goal Components give the error. I have no idea why the type casting fails. So I was wondering if this is common error and if there’s any solution. Thanks

Hello,
I have been studying some of the projects of Peter Eisenman and I have been trying to replicate his design process with Grasshopper.
He usually creates a simple geometric shape or grid and then applies a series of deformations to this. I’ve read that for deformation they apply vector forces and morphing to the shape.
When they developed the project above I noted that it is highly unlikely that they used Grasshopper because if I’m not wrong the project was made in 1996; however, I think that the process could most likely be replicated with Grasshopper.
For this reason, I had been looking at the vector fields components to enter in the mentality of vectors deformation, but now I’m less sure that with this method would make it possible to deform a shape.
In conclusion, I was hoping to kindly ask what kind of process or strategies could be studied in order to replicate the process of deformation used in the project above with the Grasshopper tools.
I thank you for your time and look forward to your response.

Hey everyone,
this might be an easy one (maybe with the PathMapper component or an Expression?) I tried whatever I knew how to operate, however I have no idea what to do, so -
I have a Data Tree with 33 Branches (each of those contains a varying amount of lines). Now I want to merge the Branches so that there are only 11. They won’t be the same size, since the amount of lines varies. I really only want it likes this:
{0}, {1}, {2} => {0}
{3}, {4}, {5} => {1}
…
{30}, {31}, {32} => {10}It would need to be correct not only for this combination, so I can use it for different situations like for from 66 to 11 Branches or 120 to 6 Branches… My problem is that I cannot flatten the original Data Tree without losing the structure… Thanks in advance

hey guys,
at the end of this code, is an attempt to extrude four closed curves in their x vector. for some reason, they are refusing to extrude that way, and instead, go in a weird direction,
ill post some pics and the code, hope you guys can help.
p.s. the starting curve is 9200cm long.
if you have any q’s, feel free.Thank you!

Hi!!!
I’m Hisashi from Japan.I’m trying to Create a Spline Curve from coordinate data output from digitizer.
I got the following data from the digitizer.
The data contained coordinate values and some words.
・NAME/C → This is unnecessary.
・PIN → This is crease of curve.
・TAN → This is end of curve.

Hello guys!
I try to make an amphitheatre so I started to make a definition. However, I have a query. I divide 2 curves and i created a number of lines between them so now I want to create some steps but when i try to loft the curves I take a single surface. So I would like to know how can I create separate surfaces from lines in order to extrude them to create boxes. I tried to split the surface with the lines I have but I take an error.
Thanks in advance!

Is there a way to code in C# like,
if (I just changed the name of a function) {
Now disconnect all the output lines from this function;
}or something like,
if (the last operation in grasshopper is CURVE) {
I’ll update how many curve functions are present in current grasshopper page;
}Hope I described it clear, I hope to find a attribute in C# to detect the last operation in grasshopper, so that can help me to create some kind of work flow.
Thanks

Is there any way Rhino6 can automatically detect the minimum radius for a curve and correct it to fit a tolerance? See illustration below. This would be a huge time saver for drawing things that have to be machined with a cutter that has a limited minimum diameter. I can compensate for this when I generate a toolpath in CAM but I am looking for a way to do this to the drawing.

Hey guys,
I have a Mesh that I’ve drawn on in Paint3D, now I want to read the Texture in relation to the Mesh. So that I’ll get the Texture and the unrolled Mesh on top of it.
In the end I’m interested in the brightness on certain parts of the Mesh.
It that possible? I just want to read the mapping information.

Hello everyone!
I’m trying to create a hexagonal pattern on an irregular surface and I’m using lunchbox’s hexagon cells component. However, in order to obtain the result I want, I need the values in the v direction to decrease along the surface. I’ve tried different things, but nothing seems to work. Does anyone have an idea on how to solve this?
Thank you!

Dear all,
I am new to the GH world and although I scanned the forum I couldn´t find a solution yet to this:
- I want to have a friendly User Interface on our homepage to enter the data we need for GH
- this should be transmitted in real time to GH on a cloud service (ideally via Excel data entry mode).
- Grashopper should then be connected (in the cloud) to Dynamo for the visualization ( evtl. with specklr)
- Data renderings should run in the cloud and results shall be displayed in the User Interface again.
The idea is to have a solution for non GH & Dynamo savvy people who need a first quick analysis.
Any ideas on this?
Best, Charly

Hi guys, I’m having a lot of trouble to achieve that result. I was able to make the panels but know I want to make those little bump wave patterns inside.
I actually don’t know the best approach for this. I was trying to subdivide the little surfaces, but they keep the radial subdivide scheme of the spheres. I know this has to do with the trimmed surface problem.
Anyway, do you guys have some idea?
