control point edit from a sphere.
Since it is the first time I try Exoskeleton, I checked the lists of input geometry in the exemple and got the same in my definition, but the component turned red, giving this error message:
1. Solution exception:Index was outside the bounds of the array.
For the Radius at Start and End values, I tried using the same principle applied inside the Exo-vase exemple, which links the radius to the Z values, remapping them from .3 to 8.
Is there the problem or elsewhere?
Could someone give me a hint about what I am missing ? Many thanks!!!
Below a screenshot., and I attach the definition.

ay be other issues with your geometry, but this is usually the issue people run into.)
Rays will lose energy much more slowly when a room is very reflective, but such conditions only really exist with polished painted concrete. I don't know how many such rooms you've ever been in. I can count them on one hand - and I've been to acoustic reverberation chambers on 3 continents.
Pachyderm works with a ray decimation algorithm. This means that a ray will be traced out to the cutoff time, unless it has lost enough energy that its further contribution to the impulse response is negligible. At this time, the ray is discontinued. So, the more absorption in the room, the less time it will take to run the simulation. So, more realistic absorption coefficients will allow a model to run in a more reasonable amount of time.
Gypsum board/Plasterboard will typically be between 8 and 11 percent at mid and high frequencies, and higher at low frequencies, for example. Concrete, unless polished and painted, is still a little porous, so you can probably make it 3 to 5 percent.
Regarding sources and receivers, adding more receivers adds almost nothing to calculation time (until the every end, when it extrapolates a pressure response, anyway). This is because the receivers are entered into a spatial partition system, which allows it to be done in an optimized way. Adding multiple sources will effectively multiply the calculation time by the number of sources, because the simulation needs to be repeated for each source individually.
Hopefully this helps you figure out how to run simulations with reasonable run times.

I'm wondering how hard it would be to have an edit box which shows the
number the user could click inside of then type in a new number, then
hit enter. :)
2) How would I go about using one line from a table and assign each
field to a variable? Then, move a slider or something and use the values
from the next row?
background: I'm recreating elbows, Tees, and other fittings using
paramatric scripts, then baking and exporting them. Here's one source
table, http://www.wardfittings.com/Assets/PDFs/0902CatalogColorOld.pdf
page 5, the uniform elbows.
Current Setup: the attached ghx file. Create a point at 0,5,0 in a blank
document with units set to inches, then assign that point to the top
left 'Center Pnt' in the ghx file.
Current workflow:
a) Modify variables A, B, H, and Nominal Dia to match one line from the
table in the linked PDF file, page 5, table of regular elbows.
b) Select the 'Nodes' and 'Surfaces' with a drag box
c) Click 'Bake'
d) Switch to Rhino window, do the 'sellast' command.
e) Drag baked objects along Y axis so the center point is at 0,0,0
f) Run 'Join'
g) Run 'Cap'
h) set the 'node' points to a layer called 'nodes'
i) set the surface to a layer called 'fit-3d'.
j) select the surfaces and nodes
k) export selected
This elbow that I'm doing only has 12 rows, so doing it the above method
doesn't take THAT long. I'm also going to be doing a couple with larger
tables like the Tee on page 8, and in other spec files. As you can
imagine, entering in EACH value into a slider is a bit tedious.
I'd love to take the pdf table, run it through an OCR program to convert
to excel, modify the headers so the ghx script knows what they are, then
paste it into grasshopper, or save it and have grasshopper read it, and
I be able to move a slider or something to to select one line at a time.
Has anyone done something similar? ie: assigned one row in a table to a
predefined set of variables, each variable coming from one field in the row?
Thanks for taking the time to read this message. :)
I'm making a rhino script to do steps d-k, so that part will be much faster.

tal fabrication tools. DLAB will investigate natural growth processes in relation to innovative concepts of architectural tectonics and fabrication. We will carefully interweave these concepts with interaction and participatory design to create full-scale working prototypes. The programme will be formulated as a two-phase process. During the initial phase participants will benefit from the unique atmosphere and facilities of AA’s London home. The second phase will shift to AA Hooke Park campus and revolve around the fabrication and assembly of a full-scale architectural intervention.
Some of the most prominent features which the participants will be exposed to during DLAB include:
Teaching team: Participants engage in an active learning environment where the large tutor to student ratio (5:1) allows for personalized tutorials and debates.
Facilities: The Digital Prototyping Lab (DPL) in AA London houses cutting-edge facilities for the fabrication of physical outputs through digital fabrication techniques. The facilities at AA Hooke Park allow for the fabrication of one-to-one scale prototypes with a 3-axis CNC router.
Computational skills: The toolset of DLAB includes but is not limited to Rhinoceros, Processing, Arduino, and Grasshopper.
Theoretical understanding: The dissemination of fundamental design techniques and relevant critical thinking methodologies to the participants through theoretical sessions and seminars forms one of the major goals of DLAB.
Professional awareness: Participants ranging from 2nd year students to PhD candidates and full-time professionals experience a highly-focused collaborative educational model which promotes research-based design and making.
Fabrication: According to the specific agenda of each year, a one-to-one scale prototype is fabricated and assembled by design teams.
Lecture series: Taking advantage of its unique location, London, DLAB creates a vibrant atmosphere with its intense lecture programme conveying the diverse expertise of professionals in the areas of digital design and fabrication techniques.
Applications
The deadline for applications is 8 July 2013.
An application can be made by completing the online application form or completing the PDF application form and emailing it to visitingschool@aaschool.ac.uk.
Fees
The AA Visiting School requires a total fee of £1,660 per participant, which includes a £700 deposit and a £60 Visiting Membership.
Fees are non-refundable. Fees do not include flights. Train tickets between London-Hooke Park, accommodation, food in Hooke Park, and materials are included in the fees.
Students need to bring their own laptops, digital equipment and model making tools.…
his comes in the form of an HTML page with links to every component, so you will need to view it in your web browser. (I use Chrome and it doesn't seem to be working correctly, but when opened in IE its fine.)
2) Included in each help topic for each component is the Inputs and Outputs descriptions and data types.
3) You supply the data. What you supply and how you supply it is for you to decide. There are umpteen different ways. Are you asking for a list of those ways for each input?
4) Points can either be Rhino objects or 3D co-ordinates. To create a point you can use any of these methods, but it mostly comes down to user preference. I like using Panels as this displays outside of the component.
5) Because of the nature of vectors they represent magnitude and direction but they don't have an independent location, so there is a component that will display vectors in Rhino.
6) The user.
7) There is a Primer on the front page. Here you find the Basics, but because GH is ever evolving in its current beta state you might find things that aren't relevant any more or simply don't work the same. And here is the reason why nobody is writing an update because it could be soon out of date.
8) Importing images by either dragging them from explorer onto the canvas or right click context menu Image...
9) Single line = Single Item of Data. Double line = Multiple items of data on the same Branch. Dashed Double Line = Multiple Data on Multiple Branches.
10) User preference
11) Toolbar management is probably the bane of David's life. Most things are logically placed. For example the Curve Tab, Primitives are any simple curve types that you are creating from scratch. Similarly Splines is for more complex curve types created from scratch. Analysis is where you find components that are finding answers supplied by curves, control points, curvature, parameters, end points etc. Division is a subset of this category but has a group of its own. And Utilities is where you find curve related actions that you want to perform, offsetting, rebuilding projecting, exploding etc.
12) I would image it would have been the Point On Curve component in Curve>Analysis. Why that group? You are not putting a point on a curve you are analysing a curve for the location of a point based on some parameters that you are supplying. For example "what is the mid point?"
I hope this goes some way towards answering you questions. No doubt this will have generated more so don't be afraid to ask, it took me several releases of Explicit History (aka Grasshopper) before I realised what the egg did, it never occurred to me that I could put my objects into Rhino when I was finished. Or the fact that I could use panels to 'see' data outputs.
Al the best,
Danny…

should follow the instruction which mostapha has wrote in https://github.com/mostaphaRoudsari/ladybug/blob/master/resources/I...
Instructions for Installing Ladybug + Honeybee: (Follow steps 1-6 for basic functionality and 1-11 for full functionality) 0. If you have an old version of LB+HB, download the file here (https://app.box.com/s/ds96em9l6stxpcw8kgtf) and open it in Grasshopper to remove your old Ladybug and Honeybee version. 1. Make sure that you have a working copy of both Rhino and Grasshopper installed. 2. Open Rhino and type "Grasshopper" into the command line (without quotations). Wait for grasshopper to load. 3. Install GHPython by downloading the file at this link (http://www.food4rhino.com/project/ghpython?ufh) and drag the .gha file onto the Grasshopper canvas. 4. Select and drag all of the files in the "userObjects" folder (downloaded with this instructions file) onto your Grasshopper canvas. You should see Ladybug and Honeybee appear as tabs on the grasshopper tool bar. (If you are reading this instruction on github you can download them from http://www.food4rhino.com/project/ladybug-honeybee) 5. Download the files at this link (https://app.box.com/s/bh9sbpgajdtmmystv3n4), unzip them and copy the contents to both C:\ladybug and C:\Users\[yourUsername]\AppData\Roaming\Ladybug. 6. Restart Rhino and Grasshopper. You now have a fully-functioning Ladybug. For Honeybee, continue to the following: 7. Install Radiance to C:\Radiance by downloading it from this link (https://github.com/NREL/Radiance/releases/download/4.2.2/radiance-4...) and running the exe. 6. Install Daysim to C:\DAYSIM by downloading it at this link (http://daysim.ning.com/page/download) and running the exe. 8. Install Energy Plus 8.1 to C:\EnergyPlusV8-1-0 by going to the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/energyplus_downlo...), making an account, going to "download older versions of EnergyPlus, selecting 8.1 and running the exe. 9. Copy falsecolor2.exe (http://pyrat.googlecode.com/files/falsecolor2.exe) and evalglare.exe (http://www.ise.fraunhofer.de/en/downloads-englisch/software/evalgla...) to C:\Radiance\bin 10. Download the OpenStudio Libraries (https://app.box.com/s/y2sx16k98g1lfd3r47zi) and unzip them to C:\ladybug\OpenStudio. 11. You now have a fully-working version of Ladybug + Honeybee. Get started visualizing weather data with these video tutorials (https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDX...).
It works for me..

WIP Anemone loop that builds gradually variable membrane modules) as a generic guideline related with the hot spot N1: how to feed Kangaroo with a proper "minimum" mesh.
By "minimum" I mean a mesh that "approximates" what are you doing PRIOR the kangaroo engagement. I'll post in some days the real case (a very complex one I confess) in order to understand why this is urgently required.
Add ons used: Starling, Paneling tools, MinSurf (Cerver.org), LunchBox, Weaverbird, Anemone, Kangaroo
Notes::
1. Use Stored Views.
2. A variety of gates is used in order to exploit all available (I believe) ways in order to deal with a mesh. The fact that the reduce mesh is not exposed in SDK ... well you understand.
3. Kangaroo is deactivated. Prior activation (see equivalent Stored View) choose some mesh "method" that you rate best for feeding Kangaroo. Of course real-time design is out of the question (see FormFinder).
4. LunchBox can't operate with trimmed nurbs .... thus the "equal" tri/quad mesh dream is a wishful thinking.
5. MinSurf (dealing with nurbs instead of meshes) can't work in a 1:1 basis (we have one membrane "base" and 2 rings or more).
6.For comparison the Rhino file has 2 outputs (depending on the fabric stress conditions) from FormFinder. Notice the way that FF builds up the mesh (MUCH simpler and this is the reason that FF is real-time).
7. Anemone loop is not complete yet (not all data tress required for creating a series of membrane variations are linked). Anemone is temperamental as well (lot's of crashes).
8. Plan Z is WIP.
All in all : a far better way is urgently required in order to feed Kangaroo with some reasonably minimum mesh (like a mini Evolute Tools pro preparing the mesh)..
