es. What I'd like to do is setup a GH definition for each step, so all I have to do is:
1 - import the flat line art of the design.
2 - "Set" the left/right eyeholes
3 - "Set" the outside profile
Then, GH would export (or sendToLayer) the appropriate curve & mounting hole combinations for each template. I have attached a sample layout where "EHT" and "OPT" are the desired geometry to export.
My main question:
Can I set up GH to "run" a whole sequence of a definition upon my pressing "run" or something? For instance: press "run", GH says "select eye holes", I click them, GH says "Select outside profile", I click it, and GH spits out all the templates I have defined (preferably in a format such as "design1_EHT", "deign1_OPT" etc.)
Thanks so much in advance for any help!!!!!

The problem is to place the "cloud" of surveyed points in a position which minimises the sum of offsets between theory and reality.
I set up a simple definition which finds the "pairs" of points, gets the distance between them, and adds up these distances : that's the value I need to minimize.
Then I set 3 "genes" which are 3 sliders :
One for a global translation of the survey ponts in "X" direction, one for a translation in "Y", and one for a global rotation around the centerpoint of my project.
The evolutionary solver was able to minimise the summ of distances by 30% !
This means that the fittings I design to connect my steel structure to the existing buildings will need less allowance for adjustments.
Cheers,

ne – power of the many è un corso advanced level che studia la produzione di effetti complessi a partire dalla modellazione di comportamenti semplici su un insieme strutturato con un numero alto di elementi. Attraverso un approccio generico e scaleless sarà possibile affrontare la tematica generale su più fronti e in una molteplicità di declinazioni possibili. Il corso è rivolto a chi,indipendentemente dal proprio background (urbanistica, architettura, ingegneria, design, arte o altro) già possiede una esperienza di base con Rhinoceros e Grasshopper, e desidera sviluppare aspetti di gestione avanzata del flusso di articolato di informazioni attraverso una strategia guidata basata su esempi pratici e sull’implementazione di un progetto personale sul tema generale del “field behaviour”. Sarà trattato anche l’utilizzo di alcuni plug-ins quali gHowl e WeaverBird. Il numero dei partecipanti è fissato a un massimo di 20 per offrire un tutoraggio proficuo ed una effettiva esperienza di learning ad ogni iscritto.
[.] Temi:
teoria
. complessità, emergence, effetti di campo (field behaviour), sensibilità, efficienza multiperformance

ies a step further towards informative models, how to extract data through a parametric process and design analysis which leads to performance based schema.The workshop will cover some advanced modeling techniques in grasshopper along with some useful grasshopper plugins "GECO,WEAVERBIRD,KANGAROO and more". An introductory to ecotect analysis will also be inculded.The workshop is dedicated to intermediate Grasshopper users " knowledge of GRASSHOPPER equivalent to which gained in Parametricisim WS or higher is preferred".Knowledge of ECOTECT is a plus but not necessary".

p to 32, not 30. I didn't see anything about the pattern that inspired me to generate the sequence parameterically, so I moved on to dividing the curve.
I entered the sequence of numbers in a 'Panel', parsed them using 'Text Split (Split on comma)', divided the length of the curve by their sum (32 from 'Mass Addition').
Multiply each number in the list by that result. This gives the length of each sub-curve/segment.
'Remap Numbers (ReMap)' lengths from '0 to curve length' to '0..1'.
Use 'Series' and 'Sub List (SubSet)' to sum up ('MA') the segment lengths preceding each curve point (0..0, 0..1, 0..2, 0..3, etc.). These are the 't' values needed for 'Shatter'.
'Flip' the output of 'MA' before passing the list of 't' values to 'Shatter'. "Flatten' would work here too but experience shows that 'Flip' works better if you want to handle multiple curves.
This works with any sequence of numbers as inputs - integers or floating points.
…
frequency in Hz, however I am a bit confused on some of these other inputs and outputs, such as "NModes" for example.
Essentially, what we are trying to do is take a floor slab and:
1) Assign zones, such as corridors to the slab (presumably subdivided meshes)
2) Give that slab/zones a walking criteria (footfall in steps/minute) - corridors have a greater walking criteria for instance
3) Output the Mips (micro-inches per second) value for particular affected areas/zones on the slab - can be represented in some color range for the respective values accross the mesh.
4) Assign slab thickness based on optimized zones of vibration
So, to summarize - based on an input slab, we would like to calculate the mips produced on a floor-slab based on pedestrian footfall in steps/minute, then use this data to determine specific slab thicknesses. I am not sure if this can be achieved using the natural vibrations component or not, or if there are other tools that can achieve this calculation in Karamba.
Unfortunately I don't think I can provide an image at this moment, but it is basically a simple 30'x30' column grid in a 6x6 matrix, and more speculative at this point.
Either way, amazing tool! Cheers!…
ntainers and a list of items to be packed. Only rectangular items are recognized, so if the input consists of arbitrarily shaped BReps, their bounding boxes will be considered. It outputs a GH_Structure of items per container, and a supplementary list of items that did not fit in any container.
There is an option to choose whether sorting of elements and containers should be performed before packing. While sorting usually yields better results, disabling allows the user to perform their own sorting before inputing the elements to PackRat. There is an input for obstacles within the volume, as well as an option to select whether the objects to be packed may be rotated or not.
PackRat comes in two flavors: - A limited Evaluation version, available at non cost. - A full-functioning commercial version.
In addition to those two, version 0.4 of Packrat will remain available for free (non-commercial) use.
The evaluation version has the following limitations: Maximum number of elements to be packed cannot exceed 30. Maximum number of containers cannot exceed 3. The component will notify if any of the two limitations is in effect.
…
onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.
