DP ($$$ aside), GC, and Grasshopper. Arthur’s original question is very important
and the exact question (and hopefully answer) I was hoping to find on a
forum.
“How to take intelligent 3D parametric generative design models (scripting, etc.) into 2D documents?" Or, deliver the 3D design for evaluation, bid, construction, etc.
I am intrigued by Jon’s comments in the same thread and would like to know how I can learn more about the process (and
pitfalls) of turning over a 3D digital generative models to a contractor/fabricator.
Are there any industry guidelines established I could use as a reference to guide our firm through this type of uncharted territory?
Arthur’s question is very reminiscent of 10 years ago when I was frustrated with the amount of time spent on the development of a 3D model design (physical and/or virtual) only to have to wipe the table clean and start the process all over again in 2D in order to document the project for delivery. From this I jumped head first into BIM and Revit, vowing never to go back to unintelligent 2D line work. I am now working on Bentley software (v8i: Microstation and Bentley Architecture) with the access and desire to venture into Generative Components. I am very intrigued by Rhino/Grasshopper primarily with the apparent ease of use and available resources assisting in the learning process – something not really available with Bentley.
In hindsight, as I am doing my software research I think the current use of Revit and BA (Bentley Architecture) are more of a “bridge”
between the past (decades of digital 2D work, i.e. AutoCAD) and where hopefully
we all will be someday in the near future (100% 3D modeling, i.e. Digital
Project??). Without having the experience
it would appear that DP/CATIA (PLM software) are closer to this than any other
type of software. As complicated as the
industry standards are for the automobile and airline industry, I feel we
(architectural industry and others) are heading in a similar direction with
total understanding (PLM/ Evidence Based Design) of a design (a whole other topic). If anything I think the market will begin to
demand it sooner or later.
Gehry (DP) article NY Times:

I know these type of broad discussions (software vs. software) can be blown out of proportion on forums, but I am would like to read
the pulse of those who are already in the trenches (using Grasshopper, CATIA, Digital Project, Generative Components, others??) and hear your thoughts. Just as valuable would be other threads,
industry articles/reviews of 3D parametric generative design software.

work with color to fit it into this logic (porous structure)?the range of colors: from white to yellow, orange, red. to blackis not so nice, saying, does not match to the design of the house.So there for it should only show the material what carries this pattern.So my question in yours case:i think that the picture of you must be thought as invert, so that it's become functional as well. if you thought this as invert,than you musst icrease the surface division,so that the rays of the sun can be disturbed to penetrate the house.that is a good the example:http://www.detail.de/inspiration/fuenf-hoefe-in-muenchen-100701.htmlin your case, the function of the patterns would get parametric significance. where more sunlight, consequently a denser pattern, and of course vice versa.therefore, the attractor should be the solar/sun system.http://digitalsubstance.wordpress.com/2011/12/07/facade-porosity-ad...What do you mean, i still see a version of you?http://www.youtube.com/watch?v=JoqDYcCDOTgThanks…
roduced the same error.
I tried to run them again with the file already open and I got this (I imagine predictable) error:
Sorry! But the number of available CPUs on your machine is 4.
Honeybee set the number of CPUs to 4.

@Mostapha, if it is indeed a different issue, what do you think it could be?
Thanks again,

them can be addressed before winter.
Bugs:
. Vector preview is great, but it doesn't refresh (clear) when you disconnect components. You must delete the component or reconnect to refresh the vector previews.
. When passing values through a note pad, note pad fails to update continuously. Moving the notepad updates the display.
. Cannot pass a notepad integer into an fx1
. Point preview in RH5 appears as large red blocks, not as red crosses. (This is an old bug, may have been fixed with RH5 update in the meantime.)
. After adjusting Graph in dialog box, graph appears to be a solid grey object until moved.
. After copying and pasting, a lot of components are broken, return nulls. Requires reconnect to recompute (haven't had this problem in a while, will see if I can find a file that recreates it)
. BIG ONE: Loading a graph mapper with a file not found creates broken file... graph mapper disappears off canvas and the output wire appears turns orange and appears to be coming from the 0,0 pixel of the canvas. This happens any time you try to port a .ghx file to another system with different drive letters/paths, etc.
Wish list:
Mass addition for vectors
Interactive domain control for Image Sampler (like with Gradient Mapper)
Allow Addition Component to handle String values (A + B = AB)
BIG ONE: Request Override for Icon display for Parameters, Wireless receiver, and script components if you change the name
BIG ONE: Add new behavior for Stream Filter and Stream Gate: Allow multiple index numbers. The Index number picks the value/object in the corresponding index position in the selected list.
For instance:
List 0: A, B, C, D, E
List 1: 1, 2, 3, 4, 5
List 2: .1, .2, .3, .4, .5
Index Stream: 0, 2, 2, 1, 1, 2, 1, 0, 1
Results: A, .2, .3, 4, 5 (This is new behaviour and more useful than Weaving)
I have attached a GHX that includes VB components that do this, but it would be better to have GH components with I/O manager options and data matching behavior, etc.

curves A and B.
For each point pA on curve A,
you need the corresponding tangent vector tA on curve A, and the lists of "cone" vectors pB(j)-pA and tangent vectors tB(j) on curve B. so you have three vectors tA, tB(j) and AB(j)
these three vectors define a parallelogram thas varies along j
3d determinant of the three vectors above gives you the volume of this parallelogram. When 3dDet = 0 then it means it's flat, the vectors are coplanar. Thats what we're looking for.
So you just need to plot the curve 3Ddet = f(pB) , still for each point on A
'pB is the parameter here'
graphically solve these cuves to find the zeros and you feed back the resulting parameter in curve B. draw te line, done.
You can manage double solutions or cusps directly on the plot by using clostest point and >= conditions to kill unwanted results.
I do it twice, from crv A to crrv B and from B to A to make sure I catch start and end generatrices each time.
The videos you posted are interesting. I don't understand how it works with just 2 slider to tune the curves.
…
as passing this extra check and because of that it was running faster. It doesn't mean that the first analysis is totally wrong as it depends on the analysis case and should be checked and optimized before running the final analysis.
You can read more about radiance parameters here (http://radsite.lbl.gov/radiance/refer/Notes/rpict_options.html), and here (http://radiance-online.org/community/workshops/2011-berkeley-ca/pre...). Since you have a light-shelf I suggest you to add to the number of ambient bounces (ab).
Now back to your wish to have the analysis run faster you can comment the line hb_writeRADAUX.checkInputParametersForGridBasedAnalysis() inside Honeybee_runDaylightSimulation and it won't overwrite the initial values but make sure that you run a number of test cases and compare the results between the runs.
Back to your definition, it looks good to me. You could have saved yourself some time by using MassToZone component and then just adding the ceiling separately but there's nothing wrong with your approach.
The main place in the definition that can change is how you're generating the vertical fins. I imagine you can use a single set of components to generate every group of the fins but again your definition will work.
I updated your file to the latest version, which means you also need to update Honeybee and Ladybug in case you're looking to modify the file.
Hope it helps,

ace when I start running Galapagos/Octopus (below is "room orientation optimization" shared at http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Room_Orientation_Optimization&slide=0&scale=1&offset=0,0) It may take quite some time to see some results. That's fine for the above simulation. But my real challenge is, when I am going to optimize room dimension with respect to ASE and sDA calculations, either Galapagos or Octopus goes wildly and never come up with a solution. I believe the time-consuming calculation, especially sDA with higher -ab numbers, trigger the lag a lot? Any suggestion/trick to improve it?
Most importantly, based on your experience, for example to optimize window/exterior shades sizes and achieve ASE<10% and sDA>55% (LEED v.4 requirements), Octopus (due to its capacity of multiple objectives) is the only choice? Any other approaches within grasshopper?
The alternative approach in my mind as a GH beginner is as follows. But I am not sure whether it is doable. Again, your comments will be greatly appreciated.
Since all my room/window/shades dimension are controlled by number sliders, I am thinking whether a component from GH will trigger these number sliders (not necessary to be all of them but one by one) automatically. If this is possible, I can do "data recorder" to record outputs from ASE and sDA. Eventually I will have a database of the input parameters and sDA/ASE results.
Does it make sense? Is there a component which can trigger number slider output at certain step?
Many thank!
