and perpframes
3) Ellipse on perframes
4) Series + Move + Series + Scale + Series + rotate (to create generations)
5) Divide curve (ellipse) + Dispatch only seleced points + join those points on ellipse using Intercurve + Divide the resulting intercurve
6) List items (I used list items 4 times, you could do as many). For 'i' parameter in list item i used slider to create generations. depending upon your definition, at this stage you might have to flatten your list output
7) joint the points you get from list output to form another intercurve + repeat that for all items.
8) Loft the curve
9) to form fenestrations, i again used rhino closed curves.
8) Project curve onto surface + copy trim + surface to mesh + mesh thickening from WB.
Hope this helps
Cheers

his project. Attached is my latest script. It seems to work for all points & directions of gravity except when the points are at equal height (in the reference plane the script creates, not in the world space). In other words, when the vector from A to B is perpendicular to the gravity vector, it doesn't work. It's totally due to the formulas used to solve for distance (see script), but I haven't found a way to fix it to make it work. Kudos to anyone that can help me figure it out!
Other notes: Required input: Point A, Point B, Gravity vector, and desired Height and/or desired chain/arch Length. Cool trick: when inputting both Height and Length, it recalculates the end point (point B) with those desired parameters, and the end point lies along the AB vector. Also, the "x" output shows either the found height, length, or distance (when both height & length are input), and "newPl" just shows the reference plane used to make calculations easier.

med that a 1000 lux measurement for a particular hour on a workplane grid point will indicate a illuminance from direct sun at that point. If I remember correctly, these simulations are to be run without the presence of any shading devices.
From an ASE calculation perspective, there are several shortcomings within Daysim (as it exists right now). The daylight coefficient method, which Daysim employs, calculates illuminance by dividing the sky into discrete patches. (http://naturalfrequency.com/wiki/sky-subdivision) For a clear sky with sun, the luminance from sun is accounted for by approximating the position of sun into 3 (as far as I know) patches. That in turn leads to an incorrect estimation of both position and luminance contribution of the sun.
Anyways, as I wrote in the begining, in my opinion the closest you'd get to calculating ASE from daysim right now would be running an annual daylighting calculation with Honeybee by setting ambient bounces as zero. A better approach, in case you are not trying to comply with something like leed v4, would be to do a DGP analysis as Chris mentioned in his post.

i projected my surface on XY plane, created voronoi curves on the planar surface and re-project / map the curves onto the subject model.
However, i'm not getting a desired result.
can any-1 please help me. or even show me a different way to model it via GH? I donot want to use rhino objects.
I have attached my initial sketch, GH and Rhino files.
Hope to find some solution so I could move forward :-(
Moreover, I could not convert the initial non-planar curves into surface hence I converted them into Mesh (thanks to 'Brian Harms' for helping me out). However, the protruding edges of the mesh is not a smooth NURB curve, it forms kind of vertices of a polygon. Any way to smoothen / fillet it? Will it affect when i commence 3D printing?

/ interest to some of you. I'm attempting to generate "bricks" along an arc, the span of the arc is known (Line AB), as is the desired brick edge length (shown as chords on the dotted circle). Im am essentially trying to solve for the diameter of the dotted circle and its center point (C). The variables within the grasshopper script would be span (X), chord Length (Y) and number of segments to the arch (N). Lacking the radius or central angle means that Im unable to solve this using my limited knowledge of Trig.
I guess the key issue here is that chord length and number is driving the radius of the arc / circle. Hence why Im not simply using the divide curve tool.
Any input members might have would be fantastic and I'd be very happy to share the resulting file.
Thank you!

join site boundary curves with voronoi curves so that voronoi curves at the edges becomes a closed polygon?
2)I want to create a line between voronoi curve control points and voronoi cell centroid points, such that each 2D voronoi cell is broken down into a sets of triangles. Please refer attached sketch.
3) Then How do i project voronoi curves along with triangl curves onto a vaulted roof?.
4) lastly, i want to give some thickness to those curve. i.e. the curves basically are structural beams of the roof. with my definition pipe command does not work very well i.e. pipes intersect and crossover at each vertices, which is not my intention.
attached is a sketch and my definition.
Can any1 help me with any of the 4 problems?
Thank you very much

g a problem though when trying to set a daylight simulation with some determined radiance parameters. Here's the problem: After many tries I think I found out that setting -ab = 6 and at the same time -aa = .05 creates some sort of problem, because when I try to do so My PC blocks for several minutes, without letting me manually end processes from taskmanager, and when I'm able again to enter grasshopper, i get the following error:
"Solution exception:index out of range: 0"
Does this really depends on the parameters and values I found out or is it related to something else? Is the problem relative to the structure of HoneyBee or is it just relative to my specific case (and maybe PC)? Is it possible to solve it, and if yes, how?
Atteched you find my rhino model and my grasshopper file.
Thanks in advance for your help and again many compliments!

he concept, moving on to decision making and continuing with digital and generative design tools TO GET THE BEST SOLUTION for each problem.
WHY? The world is complex and ever-changing and we need to be able to handle the volume of information we receive and, of course, to find and choose the best solution. Therefore, we direct our ATTENTION TO THE CAUSE, and not only on the effects/solutions.
We will learn from NATURE, the only “company” that has not gone bankrupt in over 4000M years, and it’s GENERATIVE SOLUTIONS.
> OBJECTIVES <
The participants will work in multidisciplinary groups (ex. architect + designer + business manager + constructor + communication specialist etc.) applying knowledge management tools, different approaches and nature-based optimization methods.
Listed objectives:
1. Improving the generative way of TURNING AN IDEA INTO A PROJECT through problem-solving thinking
2. Discovering nature’s ways of shaping evolutionary solutions
3. Getting out from our comfort zone and working together with other professionals in groups in order to achieve better solutions: Multidisciplinary Design Optimization
4. Learning to use technology to manage information in the decision making process

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! …
es has guided me in a - what I once thought - specific path within architecture, but recent discoveries (like the Grasshopper-community etc.) have learned me that the field of digital and parametric architecture is so-to-speak alive and kicking. This is also the main subject I would like to write my thesis about. It is however mainly the subject and defining its boundaries – what do I really want to explore and research? – which is the most difficult factor at this time.
A concrete idea is non-existant, and my current visions will probably be redirected when I have a first meeting with the promotors in February. Moreover there is the knowledge that it is impossible to make a thesis at the institute in Antwerp on no matter what subject in the world of digital architecture. Understandably too, it’s a small world and does not always result in realised projects, but in impressive imagery. At this moment however, I am thinking of two possible research fields to focus on.
In a first option the focus might lie on how digital design tools can be used to bring a certain aspect of interactivity to building facades. Such interactivity can occur both in the design phase and throughout the use of the building. The first scenario, in which the interactivity occurs when designing, I would focus on how the designer can shape a building’s outer perspective in function of environmental parameters: obstacles, elements that block sunlight from entering the building, visually important landmarks, etc. It should be noted however that focus will mostly lie on the design element, and less on the energy-efficiency and sustainability. Tools that will be researched would include Grasshopper, Rhino Scripting, Processing and ParaCloud.
A second possible approach could be categorized under both Swarm Intelligence and Generative Design and might study how the aforementioned digital techniques might be implemented in the new urbanism. We notably see more (innovative) interventions in which the design and planning is heavily influenced by movement patterns and morphogenetic parameters and functions. Based on the outcome of these scripted techniques, designers tend to work towards a proposal which answers a certain urbanistic issue.
All additional insights, guidelines, tips, comments are more than welcome in order to help me define the scope of my thesis subject. I must admit I am pretty new to this digital design world (it is not actively promoted at my home university, but it is promoted at the university where I am studying for one year now) and thus have limited experience at the time of writing.
Please also feel free to check out the blog post concerning this topic, which is a little more elaborate: http://nielswouters.be/thesis-digital-design-english/
Thanks for all your help!
