s not imported in the workflow, there is no problem for the intersectMass component, no matter how we change the random seed to generate different groups of breps with overlapping surfaces:
2. However, once we add the mass2Zone component into the workflow, we have this problem as posted here.
3. As you pointed out, the warning is given when "Hzones == True" which only happens when one of the objects in _bldgMassesBefore is recognized as a zone already stored in HB Hive. So, I added one line after line257 to print out the zone name:
4. It seems for the cases that the intersecMass component shows warning, there is a zone name printed:
5. Whereas for those cases that the intersecMass component shows no warning, there is no zone name printed:
6. Even if the zone creation is turned off, there is still zone name printed for cases that intersectMass is unable to process:
So, I agree with you that this might be related to the HoneyBeeHive which stores honeybee zones.
Maybe whenever upstream geometries change that are connected to either intersectMass or Masses2Zones, the HoneyBeeHive has to be cleaned up and zone objects inside need to be recreated.
Hope Chris and Mostapha can kindly take a look and advise if this is the source of the issue.
Thanks.

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,

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.

and Grasshopper. Recently I tried doing some test project just to see what can I do. My target is to design a small house for an atom family. Though as you might think - it'll be a parametric one. And I encountered exactly what's in the title. So here it goes: 1. Something is wrong with the measuring units in the complex profiles. I met this problem while making I-beam. In ArchiCAD it had 127/76 mm while in Grasshopper i had 127000/76200mm so a little bigger. 2. I'm unable to turn off the preview. I mean when I delete something in Grasshopper/Rhino it still exists in ArchiCAD. I have to unlock it and then delete it. 3. Coordinates for points seem broken. They have to be multiplied 1000 times to match. 4. Now one of the most important. Is it possible to somehow SHOW Grasshopper where are already made in ArchiCAD objects. Even if they'll remain still. For example I want to make a parametrical roof. Do I have to model whole building from scratch in Grasshopper or is there some fast way to "import" existing scene so I can limit my work with Grasshopper only to parametrical one. 5. Is it possible to make "points" as controlling points in AC? Like, if I'd like to make a beam in a desired place which I will mark by that point and then I will "show" Grasshopper that point and tell it to make an object in there so I can control it within grasshopper. I tried ti do this using AC Control Point but when I click "Send changes" button, Grasshopper and Rhino crush immediately. It only happens then, with control points. 6. It seems that "move" component won't work with "2D curve" component connected directly. It is possible that some of those problems are outdated. I was playing around in Grasshopper a few months ago, before summer break, but now I plan to try something new and it would be nice to know what to do. I appreciate any answer to any of those questions. Please help, you guys, are my only hope. Thanks in advance! Karol…
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,…
ut it locking up again.
I'm told we have to wait for Grasshopper 2 wed to Rhino 6, in months or years from now since Grasshopper isn't multithreaded. It does look for the escape key but not reliably at all.
Here is a response from the developer to my same sort of question:
http://www.grasshopper3d.com/forum/topics/emergency-top-for-solutio...
David Rutten: "if it was doable, I'd do it, but Grasshopper runs on the main UI thread which means that no key presses come through until the process is done. Right now I check for escape key state (circumventing the key-press events) at certain points during the solution, but the more I check the more I slow down the solution, and there are large areas where I can't check because it's not my code that is taking up all the processor power in the UI thread."
I solved my own problem in that case by leaving the solver disabled in the menu and then invoking it manually as a recompute menu command that works once anyway. That won't help you with a rogue script though, but will let you set things up without Grasshopper recalculating each change.
With the solver disabled, when you have to manually invoke a recompute, that necessary action can help remind you to save first.
I tried assigning the Rhino command GrasshopperUnloadPlugin to F4 in Rhino settings but in the test case of populating a box with 1000000 random points (Vector > Populate 3D), the freeze up cannot be ignored as you access Rhino, which remains grayed out as a program even when you highlight its window, and nor can you get any Grasshopper command-S in while its running forever. That's only the equivalent of 100X100X100 points yet it still locks up Rhino so long. Thinking in this very simple case clarifies things, since it it won't let go then complex scripts may have some better chance but really the problem is in the system itself.
At least the Rhino close box works, so you don't need the Windows Task Manager :-).
There are also autosave options in Grasshopper preferences that creates an autorecovery file for the next time you open the same document.…
learn, or as an alternative to your morning coffee + cross-word puzzle.
Rules:
Contributions can be posted by anyone. Either selected from a previously posted problem from the general discussion (please acknowledge original poster), a selection from one of the many grasshopper+ primers (please include credits) something you think is fun, curious about, or even something you want to learn.
We should keep the entries dated so we can track them. One new problem per day (so if you see one posted for today- there is always tomorrow).
User(you) adds post titled: date-name of problem.
Solutions will be posted with breakdowns, either in logic procedure, etc. And in the spirit of the NY Times, an explained solution will be posted as well within the following days.
Remember there are multiple ways to solve a problem- however the “official” post should include a “clean and elegant” (or simplest) solution. So that all learning can develop better scripting habits.
Rules: an explanation.
1- Submission categories are as follows:
Native
Plug In
Scripted
Each category should have a difficulty rating - 1 to 5 perhaps.
They should be included in title for clarity-
Date_NameOfProblem_Native Plugin or Script_Difficulty
2. Since we are an international community, and this is an open group- a C+G day starts at the time of 10 am local poster’s time.
3.Anyone can set the next question. However the same person cannot set two days in a row. If a question is up- then next person needs to wait until the following day to post. You can PM Danny Boyes or Myself (Monique) if you are having posting issues- (i.e.: how to post, or have been trying to post, but keep missing the opportunity)
4. Answers are presented in the typical grasshopper community response way: in the form of examples, and/or screen shots. For screen shots: make sure the nodes are legible, if you do a function inside a node make sure we can see what you did. Verbal explanation. Maybe picture of result.
The difference between this group and the general discussion is that the poster should know how to solve the problem, be able to post a solution up themselves.
5. The poster judges the answer. They should offer a sample solution as well when they declare the winner.
However overall quality control may be checked by moderators of the group.
6. Still thinking about this one. …
