uick answers. Below you will find some suggestions, but don't think of them as rules and especially don't think of them as guarantees.
1. Choose a descriptive title for your post
Don't call your question "Help!" or "I have a problem" or "Deadline tonight!", but actually describe the problem you are having.
2. Be succinct but clear in your wording
People need to know some details about your problem in order to understand what sort of answers would satisfy you, but nobody cares about how angry your boss or how bad your teacher or how tight your deadline is. Talk about the problem and only the problem. If you don't speak English well, you should probably post in your native language as well as providing a Google Translation of your question.
3. Attach minimal versions of all the relevant files
If you have a GH/GHX file you have a question about, attach it to the post. Don't expect that people will recreate a file based on a screen-shot because that's a lot of pointless work. It's also a good idea to remove everything non-essential from a GH file. You can use the 'Internalise Data' menu option to cut everything to the left of a parameter:
If you're importing curves or Breps or meshes from Rhino, you can also internalise them so you won't have to post a 3DM file as well as a GH file. If you do attach large files, consider zipping them first. Do not use RAR, Ning doesn't handle it.
It is especially a good idea to post files that don't require any non-standard components if at all possible. Not everyone has Kangaroo or Hoopsnake or Geco installed so if your file relies on those components, it might not open correctly elsewhere.
4. Include a detailed image of the GH file if it makes sense
If your question is about a specific (group of) components, consider adding a screenshot of the file in the text of the post. You can use the Ctrl+Shift+Q feature in Grasshopper to quickly create nice screenshots with focus rectangles such as this:
5. Include links to online resources if possible
If you have a question about Schwarz Minimal surfaces, please link to a website which talks about these.
6. Create new topics rather than continuing old ones
It's usually better to start a fresh question, even if there's already a discussion that kinda sorta tangentially touches upon the same issue. Please link to that discussion, but start anew.
7. This is not a 'do my work for me' group
Many of us like to help, but it's good to see effort on our part being matched by effort on your part. Questions in the form of 'I need to do X but cannot be bothered to try and learn the software' will (and should) go unanswered.
7b. Similarly, questions in the form of 'How do I quickly recreate this facade that took a team of skilled professionals four months to figure out?' have a very low success rate.

The webinars are divided into four groups: Essential, Advanced, Iterative and Architectural. If you are a Rhinoceros 3D or Grasshopper® newcomer, you are advised to take all the Essential sessions before proceeding to the next level. If none of the proposed topics suit your needs or if you require special treatment, you can request a custom-tailored 1on1 session. All sessions are held entirely in English.The webinars are series of on-line live courses for people all over the world. The tutor broadcasts the screen of his computer along with his voice to the connected spectators who can ask questions and comment in real time. This makes webinars similar to live workshops and superior to tutorials.…

er from moltiple curves the represent the area of floor plans,
but the problem is, I cant fine a way to intelligently divide the curves - responsively to the radiation analysis color (for example - that yelow area on of the building will have more division on each floor plan)
do you have any ideas on how to do that?
i tried to use attractors be failed miserably..
THANKS,
Limor.…
write a definition that represents the following surface that I have created out of paper.
This is essentially a squared surface subdivided into triangular segments. For that reason I was hoping I could use Zubin's example about triangles in chapter 3 of his book.
I'm sure, you guys know these kind of folding technique, but to clarify the pattern of the surface, here's a quick diagram:
My approach was to use the point cloud out of Zubani's example and select points with the Cull Nth component according to the pattern shown in the diagram. These points I would then offset with a z-vector component while keeping the distance between the points fixed.
However, after spending now several days trying to figure this out, I definitely ran into a wall..
As I see it, the example generates multiple points for the same coordinates, meaning there are occasions where there 6 points on top of each other.
Further, the Cull Nth component doesn't work exactly as I've hoped, the problem lies in the transition from one row to another..
I was also thinking instead of creating a series of points and then trying to filter specific points out to create (a) the surfaces and (b) the offset, maybe I should start creating these separate lists from the beginning?
Or, instead of point cloud series, using a surface and the sDivide component?
As you see, I am pretty confused/lost in the problem... any help would be greatly appreciated!
Thanks!

aching my skill set here, but bare with me.
I want to create an animated facade of squares which rotate depending on a sequence of grey-scale images. I've got pretty far thanks to many discussions here, but have hit a blank with exporting my animated model to 3ds max.
Here's my GH script - it's a botch of 3 or 4 various things incorporating centipede at the start and end to get the animation.
All good and it works! It produces animations which I can sequence for presentations too thanks to it's bmp export, which is sort of a side-product.
What I have a problem is that the OBJs it produces error wildly when imported to max. eg in rhino it looks like
But when I've imported them to max it looks like
and as it animates it just gets longer and smaller.
NOW I reckon it might be because my model in grasshopper is 100 separate geometries and it'd like it to be a single one - but I've not achieved that.
Does anyone have any ideas how to solve this? My end result I would like to look like this rendered still from max, but animated.
Thankyou all! This also uses Firefly, so you might need that installed to see how my file works.

t ''Morph'' turns Red saying ''Cannot morph from a degenerate box'' (image 2),
that's because every curve generates a box (image 3).
After what i check the Option ''Union'' box to make only one box for all the curves (image 4).
However, the result is aleatory and not accurate at all ... :/ (see image 6).I know you are developing Pufferfish and not ''Morph'' component, but recently you publish on instagram a video where i believe you could morph and Twist with success a collection of curves (please see image 7 and 8)...If you could give me a hint how that can be achieved, it would be awesome.(Piping/Meshing the curves with very small diameter will perhaps work and help for visualisation purposes, but i actually just need morphing Raw curves for fabrication purposes).Hope to read you very soon...Ghali,…
