can try playing around with that.
The other reasons were pretty much covered by Mostapha and Chris. Usually you want AB (the ambient bounces) to be greater or equal to 5 no matter the quality, as it is one of the most important variables for a dependable simulation. Of course it depends on the nature of your geometry but 5 min. is a safe bet.
Btw, I couldn't see which geometry you are plugging where as one pipeline was empty in the file you posted when I opened it. Could it be that you forgot a surface?
Another point is the unit range you are using. Is that really 10 lux as maximum in your picture? Because in that case it makes sense for everything to be yellow (inside and outside) as you most likely will have more than 10 lux everywhere.
P.S.: Selecting medium/high quality sets all the variables for you, no need for additional sliders. In your case you are actually overwriting the quality settings.
Kind regards,

X, Y & Z parameters. At the moment 'Z' parameter is set to 0.
Now when i use a planar surface components it works well. But because i have Z parameter i need Edge surface component to work well. Edge surface gives me a funny shape, not like planar surface.
Essentially with Z parameter as 0, edge surface should look like planar surface, or not?
When i try edge surface with simple 4 points it works. The moment it gets relatively complex i do not get desired result.
All the points 1-26 in the curve were formed progressively in order i.e. 1, 2, 2...26 in GH not in Rhino.
What m'i doing wrong?
cheers

e.
i have come as far as creating a mesh entirely in GH to my desired form. Could any-1 please help me with creating fenestrations / holes into this mesh in GH?...
I have been stuck with this since a week now...not able to find any solution to move ahead!
i have Tried Voronoi by converting this mesh in to surface...it doesn't really work on the mesh that i have created...
any-1 with some suggestions?
cheers

The comand prompt window (see attached image) seems to put -ad 1000 as default even if it seems to be set to 512 in grasshopper. In contrast to -ad, the modification of -ab to 3 has been taken into account. Have you set minimum values for RADparameters? If yes, would it be possible to force them to custom values?
Thanks in advance for your help

troducción a su plugin de modelado paramétrico, Grasshopper.
Con este tipo de herramientas podemos pensar formas más allá de las cajas para diseñar, porque seremos capaces controlar con total rigor geometrías muy complejas.
En el siguiente video, podemos ver un ejemplo realizado durante un curso impartido anteriormente en Madrid por el profesor, Francisco Tabanera, en el que se realiza una interpretación del proyecto de BIG para la Biblioteca Nacional de Kazajstán.

next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

ll geometry.
The difference with programs like Inventor is that they are made for production, regardless of the fabrication method. I won't go into detail about that, and instead focus on the modeling process.
In this little model, the starting point actually is a bit obvious, the foundation.
The only contents in the 3dm file are 27 lines. These indicate the location of each footing, and the direction of the tilt of each column. Everything else is defined in GH with the use of numbers as input parameters.
Needless to say, instead of those lines you could obviously generate lines and control the number of columns and panels, hence establish their layout, with any algorithmic or non-algorithmic criteria you please. That marks a major difference between GH and Inventor.
You can generate geometry with Inventor via scripting/customization (beyond iLogic), with transient graphics for visual feedback similar to GH's red-default previews. However Inventor's modeling functions are not set to input and output data trees. I won't go into detail on that, but suffice to say that the data tree associativity of GH was for me the first major difference I noticed. I've used other apps with node diagram interfaces like digital fusion for non-linear video editing since the late 90's, so the canvas did not call my attention when I first started using GH.
Anyways, here's a screen capture of the foundational lines:
In the first group of components, the centerlines of the rear columns are modeled:
And the locations in elevation for connection points are set. Those elevations were just numbers I copied from Excel, but you can obviously control that any way you please. I was just trying to model this quickly.
The same was done for the rear columns:
The above, believe it or not, took me the first 5 hours to get.
Here's a screen capture of what the model and definition looked like after 4 hours, not much:
If you're interested, next post I can get into the sketching part you mentioned, which is a bit cumbersome with GH, but not really.
I wouldn't say that using GH to do this little model was cumbersome, it just needed some thinking at the beginning. You do similar initial thinking when working with a feature-based modeler.…

ce issue with Rhino and shouldn't make an issue with EnergyPlus but just to have cleaner geometries, I untrimmed base surfaces so zones are closed brep now.
I also noticed that when you are adding multiple openings to a surface, the surface doesn't show-up in the output of createHBZoneFromHBSurfaces. The surfaces are there though and show up once you explode the zone! Again should be a tolerance issue for join. I need to take a closer look to both of these.
Also, in a number of the zones you had wall surfaces connected to createZoneFromHBSurfaces both before and after adding glazing. I removed parent surfaces so you don't end up having duplicate surfaces.
Back to adjacency which was your question, the issue happens since you have couple of zones with the same name so component was assuming them to be the same zone so it wouldn't solve the adjacency (Yes! it shouldn't. That was a bug which is fixed now). I changed the names and now it should find the surfaces that you are looking for.
Moreover, once you solve the adjacency, next solveAdjacency won't overwrite the BC unless you set remCurrentAdj to True.

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! …
