rid that works on the left and/or right edge of the components, so that it's easier to align them (similarly to the align functions that show up when multiple objects are selected)
Overall, I think we'd just need a basic grid for alignment, so whatever is easy/quick to implement might be good enough.
4) great, I didn't know about aliases - that pretty much answers my question.
Related to this, when I press F4 and search for a component, if the mouse/pen pointer is above the list, when I press enter Grasshopper will insert the component under the pointer, and not the one I have found with the keyboard. Am I missing something? In case could it be fixed?
As a side note, at the moment the keyboard focus is always on the Rhino Command Line. Would it be possible to optionally change the focus when the Grasshopper window is active so that we can insert new components just by typing, without pressing F4 or doubleclicking? I just find myself constantly using the keyboard to insert components, so that'd be a very nice timesaving.
5) Your idea would be great to manage complex panels and I think would be very nice to have.
However I was thinking of a different workflow, that could be useful - for instance - when working with several objects in Rhino that are referenced in Grasshopper as basis to create more complex objects.
For example: I have three different surfaces that are used to create framed grille elements. It would make sense to select these surfaces in Rhino and access to a panel that shows the element properties (for example frame dimensions, type of grille, etc.) - similarly to the property panel in Rhino.
Additionally, If I need to create a new grille element from another Rhino surface, I could just duplicate the RPC component along with the definition without the need of manually publishing all the parameters to a new RPC group. I hope this makes sense.
I understand this may not be an "urgent" feature, however I find that working with RPCs is very pleasant so I'd really like to see this feature expanded in some way :-)
6) Just perfect :-)
Thanks again David!

rder in which these polylines are drawn is not important (correct me if this is not the case).
2. We explode the polylines. This outputs all the line segments and all the endpoints (both groups with duplicates inside them). So we have 204 lines (including duplicates) and 246 points (including duplicates). We flatten both outputs in order to get 2 simple lists.
3. We use [dupPt] to remove all duplicates from the points list. So we get a list of all the nodes with each node contained one time, so we have 108 points.
3a. We can use [pointList] to display the index of each node on screen.
4. For each line segment we find the 2 endpoints and put them together in a list. So we have 204 lists with 2 points each. (We graft the list of lines so that the endpoints of each one will be in a different branch/list)
5. We use [closestPoint] and so for each endpoint we get the index number of the corresponding node. So we have 204 lists with 2 indices each.
6. We get each couple of indices and join them as text with a comma separator. (We flatten the data so that we have a single list with 204 texts)
7. BUT some of these 204 texts are duplicates (because they originate from duplicate lines), so we use [cSet] which returns the unique values from a list. So we end up with a list of 180 texts (one for each unique line). Instead of using [cSet] you could also eliminate duplicate lines using kangaroo's [dupLn] (which is the equivalent of [dupPt] but for lines) before step 4.
Hope it is more clear like this. I am not sure I understand what you mean by "But they are not connected in the order to form the tessellation.". If you still have problems with the definition please explain this a little better.
cheers, Nikos

truss right?
2. Trusses are NOT made via lines ... they are made by real-life components like balls, rods and other mysterious (and maybe ominous, he he) paraphernalia.Good news for you: lot's of C# stuff around me that do that (but they are not exactly "entry-level").
3. PRIOR talking to ANY FEA/FIM thingy you need to address clash situations: I mean IF a given node is doable or not (because lines they don't rise clash issues ... but rods/struts/tubes/cones do). Good news for you: lot's of C# stuff around me that do that (but they are not exactly "entry-level").
4. Then you have to use some real-life (or at least some "realistic") components like the ones found in, say, a classic MERO "ball" system (and especially the adapter cones between the balls and the tubes). Or at least "some" of them that outline a "realistic" truss.Good news for you: see above.
5. Then you could validate the whole structure AND the parts VS structural loads: I mean there's absolutely no meaning "doing the whole" without taking into account the load bearing capability of the parts. For instance, say, what happens if the geometry (i.e. the topology) is "capable" but a given bolt is weak? That sort of stuff.
6. Now ... this is Academic ... but following the "abstract" way (I don't care about bolts because I'm a student)... this could teach you the entirely wrong way to use FEA/FIM for validating any structural ability of ... anything. And besides FEA/FIM is used for making the damn thing in the real-world ... and that involves (unfortunately) "some" bolts and nuts.
I can arrange a (rather long) Skype session for a demo of all the above ... but first I strongly advise to post here a finished thing (in terms of 3d component geometry) ... and THEN we can examine the whole strategy: what to export, how and especially what could be an "interactive" (both ways) protocol/strategy in order to give the green light for that truss.
BTW: Kangaroo is a physics engine and as such it's used as an abstract "shape" finder. I have no idea what Karamba does ... but always have in mind: BIM things ... are BIM things (meaning that without a serious BIM umbrella ... don't go out when it rains).…
ate):
1) go to: https://github.com/mostaphaRoudsari/ladybug/2) click on "clone or download"/Download ZIP
3) Download and extract the folder wherever you want on your machine
4) Open the folder and open "userObjects"
5) you'll see something like this
6) open Grasshopper/File/Special Folders/User Object Folder
7) Select and delete all Ladybug components
8) Drag all components of the point 5) into the canvas of Grasshopper wherever you want or inside the "User Object Folder"... it is the same thing.
And it should be fine.
Let me know if it works.

requiredKeys_ input of the "OSM Shapes" component. This is not the source of your problem though, but still I mentioned it in case you solve your issue, and afterwards want to use the "OSM Shapes" component.
The current (Win32Exception): WindowsError is the very same error message that you reported back in February.For some reason, your Windows is not allowing the Gismo "OSM Shapes" component to delete C:\MapWinGIS_installation_folder\gdal-data\osmconf.ini file.
You previously solved it by allowing the full access control to it, so I am not sure why it is not working now.Windows 10 seems to be the most overprotected operating system among other Windows versions, at least judging by the questions people asked so far.
Maybe you can try to turn off all the services which prevent users from changing certain files, like UAC or maybe even your antivirus?
Try this:
1) Close your Grasshopper and Rhino.2) Restart your PC3) When it boots up again, in your Start menu's search box type: "UAC". Click on it, and a new User Account Control Settings window will open. Set the bar on the left to "Never notify".4) Completely turn off your Antivirus.5) Check once again if your access control to the C:\MapWinGIS_installation_folder\gdal-data\osmconf.ini file is still set to the values you previously reported in this post.6) Right-click on "Rhino 5" icon and then choose: "Run as administrator".7) When Rhino boots up, run Grasshopper, and open the newest create_3dbuildings_trees_streets.gh file from here.If none of this helps, maybe you have some other application which deals with access to files on your system? Malware removal application or similar? Try turning it off too.…

gns. There were a few issues with your case. I will try to list them, hoping that this can also be helpful to you but also other users in the forum.
1. The Rhino model contained a lot of open polysurfaces. This is a big enemy of meshing and CFD. The way meshing works is that every single open area, that can be reached from your locationInMesh with a polyline, will be included in meshing. Some of your lanscape volumes were open. I have rectified this in the .gh file attached and now they should be ok to mesh.
2. It is strongly suggested to rotate the geometry and not the incoming wind when creating the wind tunnel. This might as well have been the reason for meshing awkwardly, although can't be sure. I have rotated the geometry by 45 degrees to allow your original wind to have a Y+ direction.
3. I could see a decomposition component in your case study although I cannot be sure if this could be the reason of your problems. It was not connected to anything, but perhaps it might have been the culprit for the paralle issues you were having. I have disabled the component so the case would run in single processor, but you can freely enable it and your case will be run in parallel (4 cores).
4. Your post-processing surfaces have large parts inside the building volumes and under the landscape (if included). You will probably get some issues with visualizing some probes, although this will not affect your study in any way. I recommend to only pass probes that you know to be sure will be inside the mesh to OF.
5. If you decide to include the landscape (I have it disabled in the attached .gh file) I strongly recommend to allow for more cells than 2m. 10m would be a good start imo for this case.
6. I did not check, as it will not make your case break, but your grading was a bit imbalanced at first glance. Try and keep some balance, especially in the X-direction, and make sure to visualize the blockMesh and make sure you achieved what you had in mind.
I did not actually run the case btw, I leave that to you. I believe it will run without problems, although I cannot be sure it will not diverge (this is something that is very educational for you to deal with).
Good luck!

len , I lost all of my work (at least the 3d modeling)
And I frankly if I want to participate I´ll need to finnish up the board and i cant do the renders on my own I need more time , but I only have until 11:59 pm of July 6 to finnish up one render, if you feel up to the challenge, whoever completes it will receive 290 dollars (its all I can give) to any account you want. I basically need one single image.
It consists on 3 towers, with an organic facade, I'm including the competition board I had saved on in my dropbox, I want more or less the same perspective shown on the left of the board.
Sorry, but i'm desperate, I had it all done but well cant control everything in life i guess, only do it if you feel you can pull off a professional render.
Thanks. (contact me and I´ll give you more info on the towers, I was able to save some limited sections and floor plans .... but yeah.. limited, so you´ll have to base your work on the images I provide here.
I can give some files now, including images of the physical model.
Board: http://i.minus.com/idYpFK844DWns.jpg
Physical model: http://imgur.com/a/PywJa
Hope its enough, I'm also including one image i had where I explored the footprints of all the buildings, but its just for reference.
I know theres barely enough time to finnish it... but I dont know what else to do, do you guys think i should probably just take a good photograph of the model and run with that? I feel that would probably look very unprofessional :l but I really dont have a choice here

e curve and uses the resulting surface/subdivisions to:
1. Smooth wall surface, varied via the Image Mapper
2. Segmented wall surface, varied via the Image Mapper
3. Populate the surface with spheres (with or without the "wall" surface)
4. Ribbed wall surface (Horizontal and / or Vertical)
5. Protrussions from the surface, driven by Image Sampler
6. Wall of Tubes, driven by Image Sampler
7. Gridded Web Surface
The options have to be enabled/disabled to achieve various results, but the idea is that this script permits a variety of looks, all in one script. See attachments at bottom.
I think this is a decent example file showing a variety of things that can be done using the Image Sampler Component in Grasshopper. This is a working version, so I am sure there are a lot better ways to achieve some of these effects. Hopefully, this will help some of you out and / or inspire some ew idea.
In the script, there is a User Object I downloaded from digitalsubstance. It is a self contained point attractor cluster, super cool, super fun. Link to the site is below.

If there is interest, I will update this post with an annotated version.

oks like the design in the following images:
Concept Images:
Shape:
Design_Request.pdf CR_tower_shape.ghdiagrid.gh
Shape Routine:
Diagrid Routine:
Example and Inspiration:http://www.solaripedia.com/images/large/4226.jpg
Goals:
The goal is to create a grasshopper routine that recreates a modifiable design concept as shown in the concept images. The following parameters should be modifiable
1) The size and elevation of all the basic triangles, circles and the ellipse.
2) The elevation and shape of the opening and the shape and size of the three legs.
3) The shape of the crown. The angle of the tilted ellipse.
4) The loft shape between the edges.
5) The grid size (U,V) of the diagrid.
6) The size of the 2 pipes used for the structure.
Rhino Grasshopper Workflow:
I attempted Boolean difference of a solid (Brep) and the surface in question to create the opening in the surface as shown above but that did not work. What should i do to recreate the concept in grasshopper ? I would appreciate any feedback and advice. Thank you very much !

I followed these instructions, succeeded to build Tetgen, placed the built files in C drive directory and tried to run the definition. Then some WindowsError came out as follows which I don't know how to fix.
My working environment is;
OS is Windows 7 Ultimate 64 bit.
Rhino is version 5, 64 bit.
Grashoppper is version 0.9.0076, the latest version at this moment.
It would be great if I can have some help advice / comment.
I appreciate for your attention.
