hat aren’t completely there. BIM will have to continue to evolve some more if their supporters want to get to realize the promise that still is. I can’t say much about PLM, but I would say that both BIM and PLM should be considered in future developments of GH and Rhino. David has said several times that some GH limitations regarding geometry and data structures (central to interoperability) are actually Rhino limitations. So, I wouldn’t put so much pressure on David for this, or at least I would distribute the pressure also on the core Rhino development team.
Talking about Rhino vs. GH geometry, there is one (1) wish I have: support for extrusion geometry. GH already inputs extrusion elements from Rhino, but they are converted to breps. Is not a bad thing per se. The problem is when you need to bake several breps that make the Rhino file to weight several hundred MB. When these breps are actually prismatic, extrusion-like solids, is a shame that they aren’t stored as Rhino V5’s extrusion geometry in a file of just a couple of MB (I overcame this once with an inelegant RhinoScript that wasn’t good for other people). This was one of RhinoBIM’s main arguments. We can develop a structural model made of I-beams in GH using the Extrude components. We should be able to bake them as extrusions. That would also work for urban models with thousands of prismatic massing buildings (e.g. extruded footprints). Even GH’s boxes are baked as breps! Baking boxes as extrusions could be practical for voxelated or Minecraft-like models.
(2) Collaborative network support. Maybe with worksession handling, or something that aloud project team members to work on a single definition or in external references or something alike. I know there is another Rhino limitation on this, but maybe clusters are already going in that direction?
And maybe on the plug-ins domain:
(3) Remote control panel that could be really “remote”, like from other computer or device. There is an old Android App for that, but is not only a matter of updating. I mean, it would be great to control a slider with the accelerometer of an Android phone, but to have that on an iPhone will require another development team. If GH could support networks, a remote counterpart of a RCP plug-in could be developed as a cross-platform web app. I don’t know if you can access accelerometer functionality through HTML5 already, but for now, asking a client (or an spectator or any stakeholder for that matter) to control your sliders from gestures of his/her own phone would be awesome (maybe Firefly will fill that hole?).
(4) GIS support. GH already imports .shp files. Meerkat can even access the database, but what about writing to shapefiles or generating our own with databases processed/generated in GH?
(5) SketchUp support. Not only starchitects and corporations are using GH in the AEC. There are a lot of small firms, freelancers and students interested. Most of them use SketchUp for 3D modeling (not CATIA, neither Revit). Yes, you can import/export .skp from Rhino, but if GH could support nested block at bake time (also mentioned by others), it could write .skp files with complex relations of blocks (that are called components in SketchUp) and nested groups, going beyond what Rhino can export.
(6) Read/Write other formats. There are some challenges with proprietary formats that are not completely supported by Rhino, but they’re still a lot of open formats that are relevant to the fields of GH users, like stl and ply for 3D-printing. It could be nice to write mesh colors to a ply for 3D-printing a colored prototype based on GH colors. There are others, like IGES, STEP, COLLADA, etc. and 2D, like svg, odg and pdf. Some of them could offer special formatting options like custom data that the format supports but nobody uses just because is impractical to access this from direct modeling environments (but not from visual programming).

nteraction in the design of an enclosed volume.
Revolutions have occurred through architectural history and vary widely in terms of design methods and fabrication techniques. Focusing on inspiring natural form‐finding techniques, AA Athens VS works towards producing a large‐scale interactive prototype that alters in real‐time the perception of interior space.
Technology and architecture are coupled for the third year in Athens with a novel agenda of transforming an enclosed area and creating internal contrasting city‐life characteristics that transcend the local conditions. In collaboration with the National Technical University of Athens, Cipher City: Revolutions explores participatory design and active engagement modeling and continues building novel prototypes upon horizontal planes.
The toolset includes mainly ‐among others‐ Rhino Grasshopper, Processing and Arduino platforms. With the completion of the Programme participants receive the AA Visiting School Certificate. In 2013, the design agenda of AA Athens will connect with the agenda of AA Greece VS in the city of Patras. Participation in both Programmes will allow for a more extensive learning experience through additional tools like Autodesk Maya, Autodesk 3D Studio Max and more.
Discounts
The AA offers several discount options for participants wishing to apply as a group or participants wishing to apply for both AA Athens and AA Greece Visiting Schools:
1. Standard application
The AA Visiting School requires a fee of £600 per participant, which includes a £60 Visiting Membership. If you are already a member, the total fee will be reduced automatically by £60 by the online payment system. Fees are non-refundable.
2. Group registration
For group applications, there will be a range of discounts depending on the number of people in the group. The discounted fee will be applied to each individual in the group.
1. 3-6 people group: £60 (AA Membership fee) + 540*0.75 = £465 (25 %)
2. 6-15 people group: £60 + 540*0.70 = £438 (30%)
3. more than 15 people group: £60 + 540*0.65 = £411 (35%)
3. Participants attending AA Greece VS and AA Athens VS | 40% discount
For people wishing to attend both AA Greece VS and AA Athens VS, a discount of 40% will be made for each participant. (The participant will pay the £60 membership fee only once.)
£60 (AA Membership fee) + (540*0.60)*2 = £708
Eligibility The workshop is open to architecture and design students and professionals worldwide.

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. …
cremental release is available for download. It fixes several bugs reported in the 0.9.0005 & 0.9.0006 versions. To wit:
Computer mice with smooth scrolling would not zoom well, this is fixed.
Previewable parameters with a lot of consecutive null items would crash, this is fixed.
Identical GHA files would collide during the loading process, this is handled.
GHA files with identical names would collide during the loading process, this is handled.
Solver Undo setting was not persistent, this is fixed.
Widget ZUI Zoom setting was not persistent, this is fixed.
Markov Widget Corner setting was not persistent, this is fixed.
Markov Widget Suggestion Count setting was not persistent, this is fixed.
Drag and Drop on Document and Template preview materials wasn't recorded, this is fixed.
AssignDataToParameter() COM-Access method was broken, this is fixed.
Geometry and Generic parameters with persistent data would not deserialize correctly, this is fixed.
Operator shortcuts via the Canvas popup instantiation menu no longer assigned data to the second parameter, this is fixed.
Cull Duplicates component did not always show the correct label upon deserialization, this is fixed.
Legacy VB/C# components would not correctly deserialize List access on input parameters, this is fixed.
Cloud Display component would still display old sprites on disconnect, this is fixed.
Minor changes to a document would trigger lengthy preview cache updates, slowing Grasshopper down. This is fixed.
Sphere 4Pt did not work correctly, this it fixed.
Failed data conversions in parameters would result in missing entries, this is fixed.
Text Tag components (2D & 3D) would not bake via the component menu, this is fixed.
There are also some new features:
Added Jump object for quickly navigating across a Canvas (Params.Util dropdown).
Added Relative Differences component which is basically the inverse of Mass Addition (Math.Operators dropdown).
Added tooltip wiggle controls to the Preferences window, Interface section.
'Draw Full Names' now also attempts to change the display of existing components, but only in the active document.
Drag+Dropping GHA, GHPY and GHUSER files onto the canvas now puts the original file into the bin.
Replaced Set Union component with a new one that has variable input parameters.
Replaced Set Intersection component with a new one that has variable input parameters.
Replaced And and Ternary And components with a single new one that has variable input parameters.
Replaced Or and Ternary Or components with a single new one that has variable input parameters.
Replaced Concatenate component with a new one that has variable input parameters.
Concatenate component now has a segment join option available via the component menu.
Added Digit options to the Transform Matrix Display object.
Integer parameters which represent options now have more informative context menus.

Amuse yourself by trying to figure what kind of series logic could deploy (or not) these room unit combos across the blue space grid shown.
2. Let's assume that surgery etc etc departments are sited in some ground floor and their requirement for rooms is variable ... meaning that some kind of heuristic GH approach must be applied here (for instance : fill the first level with rooms required by all departments with min distance from a given core and if more are required go to next floor etc etc).
The real room unit cluster looks like that (all units are prefab)
3. Voids in the whole cluster deployment (avoid Soviet type of bloc aesthetics) mean that culling could be challenge here (we need ...er..."visual" culling , so to speak)
4. After finishing some solution create custom preview(s) in order to visualize what dept owns what rooms.
5. If in trouble with Architectural things > relax > be cool > open 3d PDF > be a great Architect in just 10 easy steps.
PS: of course I know GH clusters...but as they are they violate my rule N1: never walk the walk if no return is possible, he he. But assuming that David could resolve the return issue (sure he can) this is NOT the answer for my "proposal" for multiple Canvas - again like multiple Views in any CAD stuff these days. Just imagine clusters with some serious hierarchy depth > where am I ? what input comes from what output?
I'll be back with a chaotic case (Series in complete anarchy) in order to demonstrate the critical necessity for a visual Tree Manager/Viewer (a visual thing within the GH visual thing). For manager read : decomposer, composer, visual identifier (per data item/branch) tree re-mapper, anything actually.
more soon (and a in depth analysis about what a Tree Manager/Viewer should do - in an ideal world, that is)
Cheers, Peter
…
for this purpose. So, without paying attention to the video, this time, this is the synthesis of the process:1. generate 3d network from points and applying tensegrity physics via kangaroo:
2. option 1: generate surfaces from network using network fillet/patch tools from GeometryGym:
3. option 2: same as option 1, but this time the network is affected by the wooly paths script in order to create the 'tensioned' curves via attraction and then creating the surfaces with GeometryGym:
4. close-up:
The goal is to achieve "option 2" without using wooly paths so that the minimal surfaces are generated as the curve network is affected by kangaroo-driven tensegrity. I want the model to be a more 'real-time' simulation instead of generating the tensioned network and doing the surfaces as a post-process. I hope that explains my intention a bit more!
the wooly paths script I'm using is the "woolier paths" one or #2, I believe.
Thanks again! I hope you can help me, and sorry for any confusions!…
