oxes in the most efficient way within boundaries of object and follow the following constraints. The Goal: To fit 125 boxes in the most efficient way inside the total area. Starting Variables: (1) 40% of the Boxes need to be between 60 and 85MSQ. (2) 40% of the boxes need to be between 86 and 110MSQ.
(3) 20% of the boxes need to be between 111 and 125mSQ. The breakdown doesn’t have to be exact to give the script some flexibility. Meaning you can have 41% +39% +20% = 100%.
Constraints:
1. A total MAXIMUM area of approximately 1600M per layer.
2. A maximum of 8 layers for a total of 12,800M per layer. Optimization can make as little or as many as 8 layers vertical to accommodate all boxes. So if script can achieve with 3 levels great. If needed all 8 levels, that's fine too. However, pay attention to next constraint (#3).
3. Approximately 15% of that space on each layer is off limits. (internal area) (blue area in example script) and the shape of the boundary cannot be modified to accommodate box design resulting in jagged lines for the internal area.
4. All generated squares/rectangles must have at least 3m touching an outside border (The Green lines).
5. All boxes must also be touching minimum 1M of border of the blue line.
6. If the boxes generated go outside the green boundary, they must be fillet to maintain the straight lines of the green boundaries.
7. Get as many of the boxes as possible a view towards the dots.
Could any one provide me a method or a way to start, if there are any useful links, please share with me. Thank you!…

ey eventually recover and you can continue to working normally. This however is not very practical...
(Additional information: We have a virtualized Windows SPS environment, might this be the problem? Locally - on my hard drive - it works fine.)
Futhermore we've discovered the following bug/feature:
We export a cluster and reference it back into our .gh file, then copy the .ghcluster file to a different location and rename the copy (without opening or changing it), then also reference the copied version back into the .gh file. Now Grasshopper shows two clusters with two different file paths, but claims that they both are the same ("this cluster occurs twice in this document"). If I double click one of them, make a change and save, both clusters get changed, even though they are separate .ghcluster files.
This would follow the logic that David laid out in this entry (http://www.grasshopper3d.com/page/clusters09), that GH identifies a cluster not by its file name or location but by its internal ID.
An addition we would very much appreciate for the next GH update, would be the option to right click a referenced cluster and then not only be able to "update" it but to also to "relink" it to a new or different source.
Right now you have to rename or delete the .ghcluster file in order to relink a cluster via the update option. You can also overwrite the old cluster und update. However, sometimes we want to keep the old version or disentangle one of a clusters many instances and relink just one, with out loosing its various inputs and outputs by referencing the new version and reconnecting it.
Thanks, BB.…

2. Trad AEC BIM apps (AECOSim - my favorite, Revit - no thanks, Allplan - no thanks) use RPC cells for similar tasks (an RPC cell is in fact a "DataTree" of images). In the past I did several figure animations (I'm not doing this any more: boring to the max):

3. Maya of course does everything (it's a unique amalgam of mesh and nurbs tools), but is totally unsuitable for AEC work.

So, assuming that you are in the AEC bandwagon, your options are:
a. AECOSim as the total "umbrella" for AEC matters.
b. MODO as the most innovative app out there.
c. Quest3D as the best VR app out there.…
cy of design communication and the control of information-flow are as important as the creativity of ideas. In response to the concurrent digital evolution emerging in the architectural industry world-wide, the Faculty of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.對於高品質的建築專案,創意之外,專案過程中高效的設計資訊管理和交流成為項目設計深化和實施必不可少的環節。今天,數字化技術不但改變了建築師的繪圖工具,影響了設計的過程,而且提供了工程建造和管理實施的更有效、更高效的手段。針對建築的數位化演進,香港大學建築學院將於2011年暑假期間,在香港大學建築學院舉辦“數位化實踐”國際研習班。在香港大學建築學院教授及有著相關豐富經驗的外聘實踐建築師的指導下,學員將有機會體驗在專案的不同階段(如概念設計、設計形式的生成、優化,設計資訊的管理和交流),如何有效地應用各種運算智慧化技術(從設計的數位化生成和建築資訊類比到物理模型),提升設計實施的品質,增加設計團隊對於方案的控制。我們將挑戰對於“技術”的傳統認知,即相對於使用者它不僅是工具,更是與使用者互動的媒介,二者形成一個有機的合體。研習班期間會安排系列講座,展現數位化技術在實踐工程中的廣泛應用。…
oCommonSDK, I modified a working C# component that does something similar (ReduceMesh, written by Andrew Heumann). Both scripts are attached.
Aside from changing the component name and eliminating the P parameter, I made two modifications to the script:1) changed line 87 from private void RunScript(Mesh M, double P, ref object A) to: private void RunScript(Mesh M, ref object A)2) changed line 93 from: Rhino.RhinoApp.RunScript("_-ReduceMesh _ReductionPercentage " + Convert.ToString(P) + " _Enter", false); to: Rhino.RhinoApp.RunScript("_-MatchMeshEdge " + " _Enter", false);When I run the ReduceMesh component, the mesh object I feed it gets baked, the ReduceMesh command is run, the temporary object is deleted, and the reduced mesh result is returned. (Thanks, Andrew).When I run the MatchMeshEdge component, the mesh object I feed it is baked, the MatchMeshEdge command is run, but the temporary object is not deleted and no result is returned. The runtime error reads: "Sequence contains no elements (line 0)". I have a feeling that the command line string I am handing to RunScript is incomplete. When I enter it manually on the Rhino command line I see that it wants a mesh and three parameters. Of course I can hit Enter to accept the default values, but when you invoke a command through RunScript do you have to supply all parameters regardless? Also, where would I find details on the argument types that the command wants? For example, the last parameter reads "RatchetMode=On" or "RatchetMode=Off". How do I know if the type is Bool or the literal string "On" or "Off"?I am a complete novice at this so any help you can provide would be greatly appreciated! …
m

Can anyone help me?…
mplex the models are. If we are running multi-room E+ studies, that will take far longer to calculate.
Rhino/Grasshopper = <1%
Generating Radiance .ill files = 88%
Processing .ill files into DA, etc. = ~2%
E+ = 10%
Parallelizing Grasshopper:
My first instinct is to avoid this problem by running GH on one computer only. Creating the batch files is very fast. The trick will be sending the radiance and E+ batch files to multiple computers. Perhaps a “round-robin” approach could send each iteration to another node on the network until all iterations are assigned. I have no idea how to do that but hope that it is something that can be executed within grasshopper, perhaps a custom code module. I think GH can set a directory for Radiance and E+ to save all final files to. We can set this to a local server location so all runs output to the same location. It will likely run slower than it would on the C:drive, but those losses are acceptable if we can get parallelization to work.
I’m concerned about post-processing of the Radiance/E+ runs. For starters, Honeybee calculates DA after it runs the .ill files. This doesn’t take very long, but it is a separate process that is not included in the original Radiance batch file. Any other data manipulation we intend to automatically run in GH will be left out of the batch file as well. Consolidating the results into a format that Design Explorer or Pollination can read also takes a bit of post-processing. So, it seems to me that we may want to split up the GH automation as follows:
Initiate
Parametrically generate geometry
Assign input values, material, etc.
Generate radiance/ E+ batch files for all iterations
Calculate
Calc separate runs of Radiance/E+ in parallel via network clusters. Each run will be a unique iteration.
Save all temp files to single server location on server
Post Processing
Run a GH script from a single computer. Translate .ill files or .idf files into custom metrics or graphics (DA, ASE, %shade down, net solar gain, etc.)
Collect final data in single location (excel document) to be read by Design Explorer or Pollination.
The above workflow avoids having to parallelize GH. The consequence is that we can’t parallelize any post-processing routines. This may be easier to implement in the short term, but long term we should try to parallelize everything.
Parallelizing EnergyPlus/Radiance:
I agree that the best way to enable large numbers of iterations is to set up multiple unique runs of radiance and E+ on separate computers. I don’t see the incentive to split individual runs between multiple processors because the modular nature of the iterative parametric models does this for us. Multiple unique runs will simplify the post-processing as well.
It seems that the advantages of optimizing matrix based calculations (3-5 phase methods) are most beneficial when iterations are run in series. Is it possible for multiple iterations running on different CPUs to reference the same matrices stored in a common location? Will that enable parallel computation to also benefit from reusing pre-calculated information?
Clustering computers and GPU based calculations:
Clustering unused computers seems like a natural next step for us. Our IT guru told me that we need come kind of software to make this happen, but that he didn’t know what that would be. Do you know what Penn State uses? You mentioned it is a text-only Linux based system. Can you please elaborate so I can explain to our IT department?
Accelerad is a very exciting development, especially for rpict and annual glare analysis. I’m concerned that the high quality GPU’s required might limit our ability to implement it on a large scale within our office. Does it still work well on standard GPU’s? The computer cluster method can tap into resources we already have, which is a big advantage. Our current workflow uses image-based calcs sparingly, because grid-based simulations gather the critical information much faster. The major exception is glare. Accelerad would enable luminance-based glare metrics, especially annual glare metrics, to be more feasible within fast-paced projects. All of that is a good thing.
So, both clusters and GPU-based calcs are great steps forward. Combining both methods would be amazing, especially if it is further optimized by the computational methods you are working on.
Moving forward, I think I need to explore if/how GH can send iterations across a cluster network of some kind and see what it will take to implement Accelerad. I assume some custom scripting will be necessary.…
even (0, 2, 4) then that means the point either never hit it, or went in and out again, meaning it's outside. If it hits an odd number of times, then it must have come from within originally.
The method implements this approach using the mesh bounding box, and then striking a polyline from your test point along a vector that is defined by the upper right corner of the bounding box + a vector of (100,100,100). In the case of your failing points, this is a result of their striking an edge very precisely, which gets counted as 2 hits instead of 1 (as it should be getting captured) and passing false:
Your best bet is probably to roll your own implementation, that tests for multiple vectors:
private void RunScript(List<Point3d> P, Mesh M, ref object A, ref object B, ref object C) {
BoundingBox bb = M.GetBoundingBox(false);
List<bool> inside = new List<bool>();
for (int i = 0; i < P.Count; i++) {
Polyline a = new Polyline(); Polyline b = new Polyline();
a.Add(P[i]); b.Add(P[i]);
a.Add(bb.Max + new Vector3d(100, 100, 100)); b.Add(bb.Max + new Vector3d(100, 150, 150));
int[] fa; int[] fb;
Point3d[] xa = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(a), out fa); Point3d[] xb = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(b), out fb);
inside.Add(xa.Length % 2 == 1 || xb.Length % 2 == 1);
checkA.AddRange(xa, new GH_Path(i)); checkB.AddRange(xb, new GH_Path(i));
}
A = inside;
}
